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.

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
ꢀꢀCooling load
Choose a portable chiller that has 20% more capacity than
the process load.
ꢀꢀLocation
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.
ꢀꢀTemperature
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.

1 Turn on main power source.
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.
5
If the chiller is not working properly at any time, press the red
Stop button to turn off the chiller.

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.
