2-1  
The Conair Series 1 Portable Chillers provide self-contained  
sources of chilled water and are available in either water- or  
air-cooled models, ranging in sizes from 3.5 Hp to 40 Hp  
(approximate capacities of 3.5 tons of refrigeration to 40 tons  
of refrigeration). Pump selections are available to match most  
process flow and pressure requirements.  
WHAT IS THE  
PORTABLE  
CHILLER?  
The normal temperature range of discharge chilled water is  
20 °F to 70 °F. For applications requiring 40 °F and lower  
mix glycol with the water to the correct percentage.  
The Air-cooled Portable Chiller A1 Models and Water-cooled  
Portable Chiller W1 Models are designed to provide chilled  
water for industrial applications requiring 24-hour-a-day per-  
formance. Units are totally self-contained for easy, economical  
installation. All parts wetted by the process are non-ferrous.  
To operate, simply connect the power source, process piping  
and fill with water or ethylene or propylene glycol (but not  
automotive antifreeze).  
These chillers are ideal for machine-side cooling to maintain  
process temperatures in an injection molding machine or  
extruder and wherever you need a small, moveable cooling  
unit. Nominal capacities range from 1.44 to 14.68 tons for the  
water-cooled models and from 1.18 to 10.95 tons for the air-  
cooled models. Capacities are based on standard pump sizes  
and delivering 50 °F water.  
Operation of these units differ only in the medium used to  
remove heat from the refrigerant in the condensers. Water-  
cooled models use 85 °F (29 °C) or lower cooling water from  
a tower, well, or city service; air-cooled models use 95 °F  
(35 °C) maximum ambient air.  
Choose water-cooled portable chillers where tower water or  
another inexpensive water source is available. Choose air-  
cooled models for maximum portability of the unit. Water-  
cooled models are equipped with brazed plate or tube-in-tube  
condensers. Air-cooled models use aluminum-fin, copper-tube  
condensers.  
All standard voltages are available.

DESCRIPTION  
The Conair A1 and W1 Portable Chillers can be used any-  
where a reliable source of process cooling water - with stable  
temperature control - is required.  
TYPICAL  
APPLICATIONS  
These portable chillers are available for cooling injection  
molding, blow molding, thermoforming, extrusion, air com-  
pressors, metal plating, anodizing, degreasing, heatset/web  
offset printing presses, and dryer after-coolers.  
Roll the air-cooled condenser models next to the heat source  
connect it and plug it in. They can operate almost anywhere.  
The water-cooled condenser models require a source of con-  
denser water. Normally used in conjunction with a recirculat-  
ing evaporative cooling tower system, the units have slightly  
better operating energy efficiencies.  
Conair Series 1 Portable Chillers are designed to provide  
chilled water for industrial applications requiring 24-hour-a-  
day performance. Units are self-contained and easy to install  
and maintain. Choose the Conair Series 1 Portable Chillers  
based on the cooling load and the capacity of the unit. Pick  
your Conair Series 1 Portable Chillers based on:  
LIMITATIONS  
GGCooling load  
Choose a portable chiller that has 20% more capacity than  
the process load.  
GGLocation  
Choose a water-cooled model if the unit will be located in  
an air-conditioned area. Choose the water-cooled model if  
a source of condenser water is readily available (i.e. cool-  
ing tower water). Do not locate the portable chiller out-  
side unless the unit is specially modified.  
GGTemperature  
The portable chiller needs to provide a cooling tempera-  
ture less than 70 °F (21°C).  
Use this information as a general guide. Consult your Conair  
representative for assistance when choosing a Conair Portable  
Chiller.

of total refrigerant charge required.  
CHECKING  
REFRIGERANT  
CHARGE  
Check refrigerant charge while the chiller is running. Check  
the refrigerant charge through the sight glass. Open the side  
door of the Chiller. Use a flashlight, if necessary, and check  
the liquid-line sight glass:  
GGUnder normal load conditions, the refrigerant should  
be clear.  
GGUnder low load conditions, when the hot-gas bypass  
valves are operating, bubbles may be visible in the  
sight glass. This is normal.  
If the charge is low contact Conair service or have a local, cer-  
tified refrigeration technician add refrigerant to the system.

Check the short-to-ground with an ohm meter.  
Connect the ohm meter to each of the three terminal  
screws and to the grounding lug. Test all three for resis-  
tance. The minimum resistance to ground should be  
1megohm. If it resistance is less that 1 megohm, there is a  
leak in the system.

INITIALLY  
STARTING THE  
CHILLER  
The control boots up and the screen displays the tempera-  
ture of the fluid going to the process.  
WARNING: Initial startup  
Do not press any buttons after initially applying  
power to the Chiller. Let the Chiller set, undis-  
turbed, for a minimum of 8 hours before starting  
the Chiller. This is necessary to allow the  
crankcase heater to warm properly, and to pre-  
vent the refrigerant from pooling in the com-  
pressor.  
After the initial 8-hour minimum warmup, continue with start-  
up:  
Press the Start Chiller button.  
2
Check the Pump and Compressor lights on the control  
panel; they should turn on and off as the pump and com-  
pressor cycle on and off. The To Process temperature dis-  
plays on the control. The To Process temperature is real-  
time temperature. It should change as the chiller runs and  
cools the fluid.  
Check the rotation of the pump.  
3
4
If pump is not turning, disconnect main power to chiller,  
swap any two incoming power wires; reapply main power.  
Check for leaks inside the chiller cabinet; fix any leaks  
and dry the inside of the chiller before proceeding.  
Check the compressor.  
If the compressor is running backwards, disconnect the  
Chiller from the main power supply, switch any two  
incoming main power leads, and reapply main power sup-  
ply. Wait three minutes. The compressor should now be  
running in the proper direction.  
When the compressor is shut  
off it cannot be turned on  
again for three minutes. This  
allows temperatures and  
pressure in the chiller to  
equalize, making restart easi-  
er, and prolonging the life of  
the chiller.  
Check the sight glass on the back of the chiller.  
If the fluid level is low, follow the steps to add fluid. See  
Filling the Chiller in the Installation section.

If the chiller is not working properly at any time, press the red  
Stop button to turn off the chiller.  
UGH016/1200  
Series 1 Portable Chillers, TIC Control  
INSTALLATION 3-11  
To stop the chiller, press the Stop Chiller button on the control  
panel.  
STOPPING THE  
CHILLER  
NOTE: When you press the Stop Chiller button, the pump and  
compressor both stop. If you want to restart immediately by  
pressing the Start Chiller button, the pump will turn on but the  
compressor will not turn on for three minutes. The Process  
Pump light on the control panel will light immediately. After  
three minutes the compressor turns on and the Compressor  
light on the control panel lights. This allows temperatures and  
pressure to equalize, making restart easier, and prolonging the  
life of the chiller.  
If the chiller is not working properly at any time, stop the  
chiller and refer to the Troubleshooting section. If you do not  
encounter any problems, proceed to the Operation section.
