IMPORTANT SAFETY FEATURE  
Power Cord With Integral Safety Protection  
All PTACs rated 250V or less that are cord connected  
to the power supply are equipped with a power cord  
with integral safety protection as standard. Providing  
personal shock protection as well as arcing and  
fire prevention, the device is designed to sense  
any damage in the line cord and disconnect power  
before a fire can occur. Tested in accordance with  
Underwriters Laboratories, the cord set also offers a  
unique passive operation, meaning the unit does not  
require resetting if main power is interrupted.  
INSTALLER RESPONSIBILITIES  
WARNING - A DAMAGED POWER SUPPLY CORD  
MUST BE REPLACED WITH A NEW CORD FROM  
THE MANUFACTURER, AND NOT REPAIRED.  
This manual has been prepared to acquaint you with the

The Right Fit For Comfort  
The RetroAire Dual Motor PTAC is available in nominal  
sizes of 9,000 Btuh, 12,000 Btuh, 15,000 Btuh, and 18,000  
Btuh.* With energy efciency ratings as high as 10, the  
replacement of worn out and inefcient units is a very at-  
tractive option.  
THE DUAL MOTOR PTAC FAMILY  
The RetroAire Dual Motor PTAC is available as a cooling-  
only model or, for those who wish to up-grade to a heat  
pump, the RH10, 20, 35, 45, 80, and 90 heat pump chassis  
will fit the existing wall sleeve. The heat pump version will  
reduce energy costs during periods of outdoor temperature  
ranging down to as low as 40° F.  
* The RC12 PTAC, however, is only available in nominal  
sizes of 12,000 Btuh and 15,000 Btuh.  
All Retroaire products are backed by Enviromaster  
International LLC and are rated in accordance with ARI  
Standards 310 and 380 and UL Standard 484.  
The Dual Motor PTAC uses a high-efciency rotary com-  
pressor protected under a 5-year warranty and an enhanced  
high-efciency heat exchanger to make the replacement of  
worn out and inefcient units a very attractive option.  
PRE-INSTALLATION  
The RetroAire Dual Motor PTAC offers two fan speeds  
– three in the RC12 – and has an optional motorized fresh  
air feature with a positive pressure seal, override switch, and  
positive condensate re-evaporation to improve efciency.  
Test run the Dual Motor PTAC prior to installation. Connect  
the line cord to a proper power supply (such as the one the  
old unit is plugged into) and check all controls for proper  
operation. Disconnect the chassis before installing.  
Whisper quiet operation improves the room ambience and  
the 20 gauge galvanized steel construction of the chassis  
ensures long service life.  
Review baffle and foam tape installation to ensure proper  
air seal and unit operation.

WARNING  
WARNING  
!
!
!
!
Moving parts can cause personal injury. Exercise  
all due caution when test running the chassis.  
The correct condenser air baffles must be properly  
installed or performance will be impaired and/or the  
warranty will be voided!!  
See individual unit installation instructions for more  
information.  
PREPARATION FOR INSTALLATION  
IMPORTANT: RetroAire Dual Motor PTACs are to be used  
with metal wallsleeves. The sleeves must employ front  
panels secured by screws that prevent contact with all parts  
with minor dimensions of openings not exceeding 1/2. The  
nal assembly must employ an indoor air discharge grill  
having dimensions not less than 26” x 4, separating the top  
surface of the chassis from the top surface of the discharge  
grill by a minimum of 1. For all models, the outdoor  
openings must prevent contact of all moving parts by means  
of louvers or grills with minor dimension not exceeding 1.  
All cord connected 265 Volt units must be plugged into  
receptacles within the unit subbase or chassis.  
ELECTRICAL WIRING  
All wiring should be in accordance with the National Electric  
Code (NEC) and the local building codes.  
WARNING  
!
!
To avoid possible injury or death due to electrical  
shock, open the power supply disconnect switch  
and secure it in an open position during installation.  
On a plug and receptacle connection, keep the unit  
unplugged until installation is complete.  
1. Remove the front of the existing room enclosure. This  
will expose the old chassis.  
2. Disconnect the power supply. If a line cord and plug  
were used, remove it from the receptacle. If the chassis  
is hard wired, locate the circuit breaker, place it in the  
OFF” position, and tag it, announcing work is being  
done. DO NOT TURN ON.  
1. Inspect the existing wiring for any deciencies such as  
cut or frayed wires. Replace such wiring if found.  
2. Check the unit rating plate for circuit ampacity and  
breaker or fuse size. Use only HACR type breakers.  
Select the proper wire for the ampacity rating.  
3. Loosen any tie down bolts or screws and remove the  
old chassis.  
3. If plug and receptacle are used, check the compatibility.  
The chassis can be hard wired or direct connected as  
well.  
IMPORTANT: Dispose of old chassis per present state  
and federal regulations.  
4. Each unit must have a separate branch ciruit protected  
by a fuse or breaker. Refer to the unit rating plate for the  
proper wire and breaker or fuse size. Use of extension  
cords is prohibited.  
4. Inspect the wall sleeve/cabinet for rust, holes, and dam-  
age. Clean the wall sleeve of any dirt, repair any damage,  
and ensure proper drainage of condensate or rainwater  
to exterior of building.  
5. Remove or repair old weather seals and note location  
for installation of any new seals.  
DANGER  
!
!
The RetroAire Dual Motor PTAC must:  
6. Check the wall sleeve/cabinet to assure all drain holes  
are open and that (A) the unit is level left to right and (B)  
the back is pitched to the outside by 1/2” maximum.  
Be connected to a properly grounded electrical  
supply with the proper voltage as stated on the  
rating plate.  
7. Check the present voltage to verify the new chassis is a  
matching voltage and that the line cord and receptacle  
match.  
Use the proper maximum over current protection  
device stated on the rating plate.  
The use of extension cords is prohibited.  
8. Before installing the new chassis, inspect the outdoor  
louver for a minimum free area of 70% and remove  
any obstructions. Any variation will restrict air flow over  
the condenser coil and cause serious damage to the  
chassis. It will also void the warranty.  
Failure to follow these instructions can result in a fire,  
explosion or electrical shock causing property damage,  
personal injury or death.

or drapes that obstruct the air flow or plush carpeting  
that can obstruct the return air (see below)). Items like  
these can cause serious damage to the chassis and  
can void the warranty.  
When the unit is first powered up, high humidity condi-  
tions can cause condensation to form on the discharge  
grill. Keep doors and windows closed to reduce humidity  
and condensation will evaporate.  
The pos ition of curta ins or dra pe s  
over supply air grille may cause air to  
recirculate without cooling the room.  
The unit will short cycle and may cause  
premature compressor failure.  
1. Make sure the chassis is level. Check by pouring water  
into the drain pan and making certain it flows through  
the drain hoses to the condenser side of the unit.  
2. Plug or hard wire line voltage to unit.  
IMPORTANT: Follow the information provided on the rat-  
ing plate for voltage and amperage/fuse size for proper  
supply.  
3. Attach the front panel to the existing cabinet enclo-  
sure.  
NOTE: Any obstruction of supply air  
including the use of deflector baffles,  
may cause condensate to form on the  
louver or cabinet.  
4. Turn the power on.  
5. Check for proper operation (i.e., cooling, optional fresh  
air, and heating if supplied).  
To ensure optimum performance of your PTAC,  
avoid restricting the air flow.  
6. Check to be sure nothing will interfere with the room

RC12 SAFETY NOTE: When turning the selector switch on  
the RC12 for mode of operation, it is very important to make  
sure the switch position is SEATED” directly on a mode of  
operation (clicks into position). Do not mistakenly place  
between two positions. This can result in a potential fan  
failure while the system is in a cooling or heating operation.  
A fan failure could result in the unit overheating (smoke) in  
an electric heating mode, or freezing coil in a cooling mode.  
COOLING CYCLE:  
1. Place system switch in the COOL position.  
CAUTION  
2. Rotate thermostat knob (below) clockwise until the com-  
pressor fans start running and cold air begins to flow  
from the unit. For a colder room temperature, continue  
turning the thermostat knob clockwise and let the unit  
continue operating to cool the room and remove humid-  
ity. If a warmer room temperature is desired, rotate the  
thermostat knob counter-clockwise until the compressor  
cycles off.  
!
!
Avoid rotating the thermostat knob back and forth from  
heating to cooling. This causes the compressor to cycle  
on and off rapidly and WILL cause damage to the com-  
pressor. Allow the compressor to remain off for at least  
three minutes prior to restarting the unit.

2. Rotate thermostat knob counter-clockwise until the  
indoor fans start running and the electric coil starts  
emitting heat. The condenser fans do not run during  
the heating cycle unless the chassis is a heat pump.  
After the unit starts running and the area gets warmer,  
turn the thermostat knob clockwise until a slight click  
is heard and the electric heater turns off. If a warmer  
room temperature is desired, continue turning the knob  
counter-clockwise and let the unit continue operating. If  
a cooler room temperature is desired, rotate the thermo-  
stat knob clockwise until the electric heater cycles off.  
A. Place system switch in the HEAT position.  
B. Turn thermostat knob counter-clockwise. Motorized valve  
should open and allowhotwaterto run through the coil. The  
indoor fans will run, blowing air through the hydronic coil.  
C. Check room comfort level as outlined under Heating

MOTORIZED FRESH AIR DAMPER (Optional): The  
optional motorized fresh air damper allows the operator  
to move fresh air into the space to be conditioned. This is  
done by placing the damper door switch in the YES” posi-  
tion, opening the damper door and allowing fresh air to be  
moved into the space. To stop the flow of fresh air, simply  
place the switch in the NO” position.  
IMPORTANT: Room temperature must be below 85º F  
to energize the heater.  
3. Place system switch in the OFF” position. All operation  
should stop.  
CHANGEOVERT-STATS(HeatPumpOnly):On units with a  
changeover thermostat, the compressor can run to an outdoor  
temperature of 40° F and then shut off. Electric heat will then  
energize and assume the heating demand until the tempera-  
ture of the outdoor air rises to approximately 5F.

• Locate the limit switch.  
Push in the reset button on  
the face of the switch. (Refer to illustration above)  
CONDENSATE REMOVAL: The Dual Motor PTAC has a  
drain connection at each end of the condensate drain pan.  
This allows the condensate to drain through the bulkhead  
to the area near the condenser fan. The condenser fan has  
a slinger ring that picks up the condensate and slings it on  
the hot condenser coil where it evaporates. On heat pump  
models condensate can form on the outdoor coil during  
the heat pump cycle. A temperature sensitive valve in the  
base pan will allow condensate to ow to an internal piping  
system or external drain kit (supplied by others).  
HYDRONIC COIL: The coil with the old unit can be located  
in the subbase, under the chassis in a special attachment,  
or above the chassis in a special attachment. It is neces-  
sary to know where the coil is to be located and the physical  
size of the coil so the right coil can be supplied if ordered for  
replacement. The coil is shipped loose for eld installation.  
It should be installed in the same manner as the coil it is  
replacing. When the hydronic coil is not replaced, installation  
of the chassis should follow the instructions in this manual.  
HEATING CYCLE - Hydronic: All straight cool Dual Motor  
PTACs are equipped with a field supplied hydronic heat op-  
tion. The unit is provided with a two-position molex plug for  
motor valve connection. To wire this option, take the molex  
plug connector with (2) yellow wires from the kit and plug  
it into the molex on the unit. Then wire the opposite end of  
the molex to the motorized valve in the hydronic circuit.  
AQUASTAT CONNECTION (Optional): All straight cool  
Dual Motor PTACs are supplied with a standard high volt  
aquastat connection. The connection is located on the bot-  
tom or side with a black jumper wire installed in molex. To  
wire option take jumper wire and cut in half. Then connect  
2 field supplied wires to the cut ends of jumper and wire  
to aquastat (see wiring diagram for more information). If  
option is not being used simply leave jumper wire con-  
nected to unit.  
IMPORTANT: Make sure the motor valve is rated for the  
correct voltage. Most RetroAire units with unit mount

CHOOSING A THERMOSTAT: EMI offers a thermostat  
NOTE: The start of the compressor will not take place until  
that is compatible with your PTAC/PTHP unit. Select EMI  
part number 240-2960 from the latest Retroaire price list  
for this option. This is a single stage, cool/heat, mercury  
bulb thermostat that can be used in all Retroaire cooling,  
heating or heat pump applications. The thermostat has  
an adjustable set-point range of between 55°F and 95°F.  
There are two independent, adjustable stops that can limit the  
heating or cooling range of the thermostat. If a non-mercury,  
electronic thermostatis needed, then choose EMIpartnumber  
240-3926.  
the anti-short/random start time period has elapsed.  
ELECTRIC HEAT OPERATION: Place the thermostat  
s ys te m s witch in he a t mode . Adjus t the s e t-point  
temperature above the room temperature. The electric  
heat will energize along with the indoor fan motor. Heating  
will continue so long as the set-point remains above room  
temperature. Next place the set-point temperature below  
room temperature. The Electric heater will switch off and the  
indoor fan will remain on for an additional sixty seconds.  
HYDRONIC HEAT OPERATION (Optional): An optional  
hydronic heat package may be selected in lieu of electric  
heat. Heating operation is essentially the same as that of  
units with electric heat. With the thermostat system switch  
set to heat and the set-point temperature above room  
temperature, the hydronic valve will open allowing water  
to flow through the coil. The indoor fan will also switch on  
and warm air will flow from the unit. Heating will continue  
so long as the set-point remains above room temperature.  
Place the set-point temperature below room temperature.  
The hydronic valve will close and indoor fan will switch off  
after the sixty-second purge time has elapsed. The hydronic  
valve is a 24Vac normally open valve. Should power be lost  
to the unit, the valve will default to the open position.  
SELECTING A THERMOSTAT “By Others”: Whe n  
selecting a thermostat other than those offered by EMI,  
it is important to choose a single stage heat/cool, 24V  
thermostat. For models 09-17, do NOT select a thermostat  
that requires connection to a C terminal since these units  
do not have provisions for connecting to a C terminal.  
Only models 19 and 24 have provisions for connecting a  
C” terminal to the unit.  
If a thermostat without a C” terminal is used in a models 19  
or 24, then it is important to insulate the unused BROWN C”  
low volt wire to prevent it from shorting at the thermostat.  
COOLING ONLY WITH ELECTRIC HEAT OR HYDRONIC  
HEAT (RC- PTAC’s):Select a thermostat that is compatible  
with a cooling - electric heat system. The thermostat should  
have R, “Y”, “W and G terminals  
HEAT PUMP (Cooling Mode): Cooling operation in a heat  
pump unit is described in “Cooling operation” above. The  
unit is equipped with a reversing valve that is energized for  
cooling and de-energized in heating mode.  
HEAT PUMP WITH ELECTRIC HEAT (RH - PTHP’S):  
Select a thermostat that is compatible with a cooling - single  
stage heat - heat pump system. The thermostat should have  
R, “Y”, “O” and G” terminals. Retroaire units are single  
stage heating only. The electric heat and heat pump will  
not operate simultaneously.  
HEAT PUMP(Heating Mode): Heat pump units are Limited  
Range” equipped with back-up electric resistance heat.  
Limited Range heat pumps are designed to operate when  
outdoor temperatures are between 75°F and 40°F and with  
a maximum indoor temperature of 80°F. When the outdoor  
temperature falls below approximately 40°F the unit will  
switch from heat pump to electric resistance heat. Electric  
heat will then remain as the heat source until the outdoor  
temperatures rise above 50°F. Retroaire heat pumps (RH  
PTHP) are single-stage heating units. The electric heat  
and heat pump will NOT operate simultaneously.  
FAN OPERATION: Some thermostats are equipped with  
an auto/on fan switch. When this switch is placed in the  
on position the indoor fan will run continuous. When the  
switch is in the auto position the indoor fan will cycle with  
the call for heating or cooling.  
FAN PURGE (Optional): After the room thermostat has  
been satised, the purge feature allows the indoor fan to  
remain on for an additional 60 seconds. This increases  
efciency by pulling the remaining energy from the unit.  
To operate the unit in heating mode, it must rst be connected  
to an appropriate heat pump thermostat. (See choosing a  
thermostat). Select heat on the thermostat system switch.  
Then, adjust the set-point temperature above the room  
temperature. The compressor and fan motors will start  
and heating will begin. If the outdoor temperature is below  
approximately 40°F the heat pump system will not operate.  
Electric heat will then take over the heating demand.  
Heating will continue so long as the set-point temperature  
remains above the room temperature. Place the set-point  
COOLING OPERATION: After connecting the thermostat  
to the unit place the system switch in cool mode. Adjust the  
set-point temperature below the room temperature. The  
compressor and fan motors will start and cooling will begin.  
Place the set-point temperature above the room temperature.

HEAT PUMP (Emergency Heat)  
WARNING  
!
!
Before accessing the control compartment, disconnect  
power to the unit. Failure to do so could result in  
serious injury or electrical shock.  
Should the heat pump system fail, it is possible to force the  
control board into electric heat mode. This is a temporary  
solution until the heat pump system can be repaired.  
Locate the circuit board in the control section of the unit.  
Locate the terminals where the outdoor sensor connects  
to the circuit board. Using a small needle nose type pliers,  
disconnect one side of the sensor from the circuit board.  
This will appear to the circuit board as an outdoor coil freeze  
condition there-by energizing the electric resistance heater  
on the call for heat.  
The second is a set of two pins labeled TEST. When these  
two pins are jumped together, all timers are eliminated (i.e.  
anti-short, purge, ect.). This is mainly used for production  
line testing however it may also be useful for eld-testing  
as well. The units are shipped with the TEST” jumper on  
only one of the pins. Please, do not leave a unit with the  
test jumper in the test mode (see Firure #2).  
Figure #1  
STRAIGHT COOL/HEAT PUMP JUMER  
HEAT PUMP (Thermostatic Drain Pan Valve): Heat pump  
units are equipped with a thermostatic drain valve that will  
open when outdoor temperatures fall below 50°F. This  
keeps the base pan free of condensate water where it may  
otherwise freeze during colder outdoor temperatures. As  
part of its normal operation, the unit will produce condensate  
and collect it in the base pan of the unit. There it will be  
picked up by the condenser fan slinger ring and deposited  
onto the condenser coil. During the cooling season, this  
improves the units efciency by maintaining adequate  
refrigeration system pressures.

CLEANING THE EXTERIOR  
Before servicing the RetroAire Dual Motor PTAC, be  
sure to turn off electrical power to the unit. Failure to  
do so can result in a fire, explosion or electrical shock  
causing property damage, personal injury or death.  
1. Clean the air filter at least once a month by removing  
it from the unit and washing or vacuuming any dust  
from its surface. Allowing dust to collect on the lter  
will cause the PTAC to lose efciency and eventually  
malfunction.  
1. Disconnect power from unit.  
2. Remove access panels and do a visual inspection of  
the unit, making sure to check for obvious problems  
such as damaged coils or evidence of extended wear  
on any moving part.  
2. When cleaning the lter, be sure to vacuum any dust  
from the return air grille surface as well.  
3. Clean exterior of the cabinet as desired with a mild soap  
or household cleaner.  
3. Check for unusual odors, oil leaks, or stains on or  
around the coil and refrigerant lines. The presence of  
oil here may indicate a potentially serious problem such  
as a refrigerant leak.  
IMPORTANT: If a new air filter is needed for your  
RetroAire Dual Motor PTAC, consult factory for avail-  
ability and/or proper sizing.  
4. Inspect all electrical connections. Look for frayed wires  
and poor connections. Terminal ends that are loose will  
eventually fail, causing a loss of performance or worse.  
TROUBLESHOOTING  
5. Check fan motors and blower assemblies. Some units  
may require a drop of light oil to motors and/or bearing  
assemblies (look for oil cups). Check setscrews and  
motor mounting hardware, making sure they are tight.  
NO HEAT OR COOLING: Check to see if the unit has  
power and if the thermostat is satised. If the thermostat is  
not satised, refer to the wiring diagram and check control  
components for continuity.  
6. Brush and/or vacuum the centrifugal fan blades and  
blower cage assemblies. These parts must be clean to  
operate efciently.

WARNING  
!
!
It is illegal to discharge refrigerant into the atmo-  
sphere. Use proper reclaiming methods and equip-  
ment when servicing a RetroAire Dual Motor PTAC.  
10. Check the pitch of the unit. Over time the building and  
equipment may settle, causing a shift in the direction  
of the condensate ows. Ideally the unit should pitch  
a minimum of 5° (at least ½) to the outside to allow for  
proper drainage.
