Portable Chiller Cooling Unit
Model: COMP-PCCU-24400S
Description:
Compcooler Portable Chiller Cooling Unit (PCCU) was designed for indoor and outdoor cooling
application. PCCU uses 24V DC rotary compressor refrigeration system to cool the liquid, pump
circulates the cold liquid to cooling vest or cooling channel, then flow back to reservoir after heat
exchanged. PCCU delivers 400W cooling capacity, powered by 110/220V AC wall plug or 24V DC
battery, temp control -5℃to 30℃(23℉to 86℉), accuracy +/-1℃(2℉), once circulation liquid
reaches to set point temperature, system intellectually control the cooling capacity to that
temperature. User may pre-cool the unit and get the coldest liquid as he needs, iceless cooling
unit, maintain free. This model is good for body cooling by connect with cooling garment or
cooling pad.

System Operation Control: Chiller unit will intellectually control the cooling capacity (compressor
speed) to setting temperature. Power consumption or operation current may be changed for
different ambient.
Chiller Unit Performance Curves
Operation ambient for chiller unit is -10 to 60℃
Cooling capacity could be difference based on ambient and liquid temp setting.

Dimension of Chiller Unit
Operation Instruction
Preparation
Chiller Unit Installation:
Unit could be installed on the flat surface, make sure it is a well-ventilated area, no blocks for fresh
air inlet and outlet.
Power Connection
AC Wall Plug
One AC power cord was provided with chiller, user may connect it with wall inlet plug 110V or
220V.
Please make sure the unit voltage 110V or 220V before operation!
DC Battery Connection
One DC power cord with female aero connector was provided with chiller, user may connect it
with battery or vehicle power 24-28V DC.
Power Switch
User need to press the switch to AC or DC before operation.

7
Cooling Garment Connection
User may connect the chiller with Compcooler Cooling Vest or Cooling pad by quick release
fittings. One extension tubing was provided with chiller.
Chiller unit is compatible with all Compcooler garment, if you want to try other brand garment,
please remove the quick fitting from extension hose and replace the new fittings to compatible
with other cooling garment.
Circulation Liquid
User needs to fill circulation liquid by twice.
The first time, remove the filler cap from top side, add liquid to full by funnel, connect the cooling
garment, turn on the pump and circulates the liquid from reservoir to cooling garment.
The second time, keep running and allow the liquid cooling garment fill with water for 30-60
seconds (without cooling), refill again to full (maybe couple times, be patient), then tight the filler
cap.
Clean or distilled water is fine if ambient more than 1℃
Deionized water for isolation request.
Anti-freeze liquid for ambient below 0℃.
DO NOT use salt water, caustic, corrosive or flammable fluids!
Refrigeration or Pre-cool Testing
User may turn on the system and start refrigeration, no pump circulation, temperature will down
in minutes. Cooling unit will be in standby mode once liquid temperature reaches to setting point.

Compcooler, keep your body cool and comfortable in harsh conditions.

Operation Processes
1. Garment or Pad connection: Connect the extension tubing with liquid heating unit. Connect the
liquid cooling garment or pad at the other end.
Once you hear a click, it’s in position.
2. Power connection: turn on power switch and light the front panel.
The cooling unit will be in standby mode.
3. Start cooling: user may press ON/OFF to start chiller, liquid temperature will go down to set
point in minutes.
pump is not working at this time.
4. Temp setting: user may press up and down to set up the temp for circulation liquid as need.
5. Start circulation:
User may press the pump to start or stop circulation. Please make sure the tubing is connected
(no kinks) before circulation.

Clean and Maintenance
Chiller Unit:
Unplugged the power, use a clean damp cloth to clean the outside of chiller unit.
Use compressed air to remove dust and debris.
Reservoir cleaning
Please disconnect the extension tubing from chiller unit.
Empty the remain water or liquid from drain cap on the bottom, and open for dry.
Condenser clean
To keep the system at optimum cooling capacity, the condenser should be kept free of dust and
dirt, user may check and clean it if necessary.
Open the side panel and remove the fans, use 50-100psi compressed air to clean the
contamination.
Charging Refrigerant
(not recommend for uncertified operator)
If cooling capacity was decreased because of lack of refrigerant, user may vacuum the unit and
recharge 150g R134a refrigerant.
Liquid Heating & Cooling Pad or garment:
Machine wash, wash liquid heating and cooling pad using a front-loading wash machine with cold
water on a gentle/delicate cycle, secure the connection tubes to minimize risk of it flailing in the
spin cycle and damaging connector and tubing sewing.
Note: DO NOT BLEACH, NO IRON, NO DRYER, TUMBLE DRY ON LOW
Chiller Unit Storage:
1. Turn off chiller unit, disconnect the power cord.
2. Disconnect the extension tubing.
3. Empty the circulation water from chiller unit by open bottom drain cap, then clean and
disinfect the reservoir, then tight the cap after open dry.
4. Pack the unit for storage.
Restart: after long term storage, please fill in clean water with less degerming agent, run system
over 10 minutes with cooling vest connection. Then empty the system and re-fill in the liquid as
need.

Code
Description
1
E1
Wrong Polarity or reverse connection from power input
2
E2
Low voltage protection, less than 18V
3
E3
High voltage protection, more than 32V
4
P1
No liquid temp signal from sensor
Cautions:
1. Please confirm chiller voltage is 110V or 220V before connect AC power.
2. Please make sure battery output 20A for DC operation, or 400W for vehicle operation.
3. Please do not turn ON/OFF to run to stops system frequently within a short period, it may
affect the refrigeration system, and significant enhance power consumption.
4. Please do not block air inlet and outlet, it may cause the problem of compressor overheat or
less cooling capacity.
5. Please make sure cooling garments or vest be connected before start pump circulation, it may
cause unit leak because of pump pressure.
6. Please use anti-freeze liquid if temperature setting lower than 0℃
7. Please do not run the system close to fire or under water.
8. Max operation temp is 60℃, unit could be overheated protection in hot ambient.
9. Please stop operation and disconnect the power if high vibration or abnormal noise.
