174065-YIM-A-0206

CLEARANCES

FILTERS

All units require certain clearances for proper operation and

service. Refer to Figure 3 for the clearances required for com-

bustion, construction, servicing and proper unit operation.

Single phase units are shipped without a filter and is the responsi-

bility of the installer to secure a filter in the return air ductwork or

install a Filter/Frame Kit (1FF0114).

WARNING:Do not permit overhanging structures or shrubs to

obstruct the condenser air discharge outlet.

A filter rack and a filters are standard on three phase units.

Filters must always be used and must be kept clean. When fil-

ters become dirt laden, insufficient air will be delivered by the

blower, decreasing your units efficiency and increasing operat-

ing costs and wear-and-tear on the unit and controls.

DUCT WORK

These units are adaptable to downflow use as well as rear sup-

ply and return air duct openings. To convert to downflow, use

the following steps:

Filters should be checked monthly especially since this unit

may be used for both heating and cooling.

1. Remove the duct covers found in the bottom return and

supply air duct openings. There are four (4) screws secur-

ing each duct cover (save these screws to use later).

CONDENSATE DRAIN

2. Install the duct covers, removed in step one, to the rear sup-

ply and return air duct openings. Secure with the four (4)

screws used in step one.

A condensate trap is required to be installed in the condensate

drain. The plumbing must conform to local codes. Use a seal-

ing compound on male pipe threads. Install the condensate

3. Seal the duct covers with silicone caulking.

drain line ( “ NPTF) to spill into an open drain.

Downflow units must have an L-shaped supply duct without

any outlets or registers located directly below the supply outlet

of the unit.

SERVICE ACCESS

Access to all serviceable components is provided by the follow-

ing removable panels:

Duct work should be designed and sized according to the

methods of the Air Conditioning Contractors of America

(ACCA), as set forth in their Manual D.

• Blower service access

• Electrical/filter access

• Compressor service access

A closed return duct system shall be used. This shall not pre-

clude use of economizers or ventilation air intake. Flexible

joints may be used in the supply and return duct work to mini-

mize the transmission of noise.

Refer to Figure 3 for location of these access panels and mini-

mum clearance.

THERMOSTAT

CAUTION: When fastening duct work to the side duct flanges on

the unit, insert the screws through the duct flanges only.

DO NOT insert the screws through the casing. Outdoor

duct work must be insulated and waterproofed.

The room thermostat should be located on an inside wall ap-

proximately 56" above the floor where it will not be subject to

drafts, sun exposure or heat from electrical fixtures or appli-

ances. Follow manufacturer's instructions enclosed with the

thermostat for general installation procedure. Four or five color

coded insulated wires (minimum #18 AWG) should be used to

connect thermostat to unit. See Figure 2.

NOTE: Be sure to note supply and return openings.

Refer to Figure 3 for information concerning rear and bottom

supply and return air duct openings.

Checking Supply Air CFM

a dry coil, the compressors should be deactivated while the test

is being run.

To check the supply air CFM after the initial balancing has been

completed:

4.Knowing the pressure drop across a dry coil, the actual CFM

through the unit can be determined from the curve in Coil Delta

P vs. Supply Air CFM figure.

1.Remove the two ¼ inch dot plugs in the duct panel.

2.Insert at least 8 inches of ¼ inch tubing into each of these

holes for sufficient penetration into the airflow on both sides of

the indoor coil.

WARNING! Failure to properly adjust the total system air quan-

tity can result in extensive system damage.

After readings have been obtained, remove the tubes and rein-

stall the two ¼ inch plugs removed in Step 1.

3.Using an inclined manometer, determine the pressure drop

across the dry evaporator coil. Since the moisture on an evapo-

rator coil may vary greatly, measuring the pressure drop across

a wet coil under field conditions would be inaccurate. To ensure

NOTE: De-energize the compressors before taking any test

measurements to ensure a dry indoor coil.

SEQUENCE OF OPERATION

Heating

Cooling

The following sequences of operation are based on using a

standard single-stage cooling thermostat.

WITH POWER TO UNIT AND THERMOSTAT IN HEATING

MODE.

WITH POWER TO UNIT AND THERMOSTAT IN COOLING

MODE.

1. If the fan switch on the thermostat is in the “ON” position,

the 24 volts at “G” will energize the “K1" relay contacts, and

energize the indoor blower motor. If the fan switch on the

thermostat is in the ”AUTO" position, the blower will oper-

ate only when there is a call for heating by the thermostat.

1. If the fan switch on the thermostat is in the “ON” position,

the 24 volts at “G” will energize the “K1" relay on the fan

control board, close the ”K1" relay contacts, and energize

the indoor blower motor. If the fan switch is in the “AUTO”

position, the blower will operate only when there is a call for

cooling by the thermostat.

2. On a call for heating, the thermostat will send 24 volts to

“W1" on the fan control board. The 24 volts signal will ener-

gize relay ”K2" on the fan control board, and the first stage

of electric heat will be energized.

2. On a call for cooling, the thermostat will send 24 volts to “Y”

on the fan control board. The 24 volt signal will energize

contactor “M1", and power will be supplied to the compres-

sor and outdoor fan motor. If the fan switch on the thermo-

stat is on the ”AUTO" position, the thermostat will also send

a 24 volt signal to “G” on the fan control board and the in-

door blower will operate as indicated in step 1.

3. When the heating demand is satisfied, the electric heat will

be de-energized when the 24 volt “W1" and ”W2" signals

are removed. If the fan switch on the thermostat is in the

“ON” position, the indoor blower will continue to run. If the

fan switch is in the “AUTO” position, the “K1" relay will open

and de-energize the indoor blower motor after the appropri-

ate time delay.

3. When the demand for cooling has been satisfied, the “M1"

contactor will be de-energized when the 24 volt ”Y" signal is

removed. If the fan switch on the thermostat is energized

when the 24 volt “Y” signal is removed. If the fan switch on

the thermostat is in the “ON” position, the indoor blower will

continue to run. If the fan switch is in the “AUTO” posi-

tion, the 24 volt “G” signal will be removed, and after a

60 second delay, the “K1" relay will open and de-

energize the indoor blower motor,

settings within the limitations of the system.

MAINTENANCE

NORMAL MAINTENANCE

WARNING:Prior to any of the following maintenance proce-

dures, shut off all power to the unit, to avoid per-

sonal injury.

OUTDOOR COIL- Dirt should not be allowed to accumulate on

the outdoor coil surface or other parts in the air circuit. Cleaning

should be as often as necessary to keep the coil clean. Use a

brush, vacuum cleaner attachment, or other suitable means. If

water is used to clean the coil, be sure that the power to the unit

is shut off prior to cleaning.

Periodic maintenance consists of changing or cleaning filters

and general cleaning of the outdoor coil.

FILTERS - Inspect once a month. Replace Disposable or clean

Permanent Type as necessary. DO NOT replace Permanent

Type with Disposable.

CAUTION: Exercise care when cleaning the coil so that the

coil fins are not damaged.

Do not permit the hot condenser air discharge to be

obstructed by overhanging structures or shrubs.

MOTORS - Indoor and outdoor fan motors are permanently lu-

bricated and require no maintenance.
