STANDARD FEATURES SERVICEABILITY All AquaCooler Series units are designed with removable panels to provide full service accessibility. Turn to page 11 “Part Replacement Procedure” for removal of the correct panel when replacing a part. AUTOMATIC WATER VALVE All units are equipped with a direct-acting, refrigeration system head pressure actuated water regulating valve.
STATE-OF-THE-ART CONTROLS The AquaCooler units maintain the desired temperature by setting the 24 volt State-Of-The-Art programmable electronic controller. Turn to page 10 for simplified operating instructions. The thermostat has a setting range from 55° F to 85° F ± 1° F and also has a Celsius readout. A six speed push-button regulates the evaporator motor if manual control is desired. In automatic mode, fan speed is automatically reduced as temperature approaches set point.
OPTIONAL FEATURES HOSE KIT 10, 25, and 40 foot hose kits with flare connectors to match fittings on units, banded 3-in-one design for easy and convenient installation, are available. When using these hoses in applications with water pressures exceeding 50 PSIG, a water pressure reducing valve must be installed in the water supply line prior to the hose kit; otherwise warranty on the hose kits will be void.

INSTALLATION INSTRUCTIONS ELECTRICAL REQUIREMENTS Adhere to the data plate on the back of the unit and make certain that the proper power is used. Refer to the "Specifications" section for voltage and fuse requirements. Make sure that proper wall outlets and receptacles are used as described in "Standard Features" section of this manual. Operating the unit on improper voltage will void the warranty.
PRACTICAL INSTALLATION Proper installation can be achieved by following these simple steps: 1. Turn off cold water supply. 2. Install “T” between faucet of cold water line and supply valve. 3. Connect shut-off valve to “T” branch. 4. Insert a 3/8 pipe nipple in discharge end of water shut-off valve. 5. Thread coupling onto 3/8 pipe nipple and secure. An alternate installation method: Drill a 5/16 diameter hole in the cold water line and attach a saddle valve to the line.
CHECKOUT OF UNIT OPERATION POWER BUTTON: Press the power button once to toggle the unit to the on mode. Press the power button again to toggle the unit to the off mode. FAN BUTTON: Press and release the fan button to advance from auto to manual fan. Press and release to increase the manual fan speeds, 1 through 6. Press and release again returns to the auto fan mode. The selected fan mode is indicated by the Auto and Manual fan LED’s.
REPLACEMENT PROCEDURE FOR PARTS A. FAN MOTOR 1. Remove cabinet's left-hand (when looking at the front of the unit) side panel. 2. Disconnect motor wires from evaporator contactor and fan speed rocker switch. 3. Remove screws securing motor and O-ring to blower housing. All screws are external and visible. 4. Loosen clamp around motor and remove motor. 5. Install new motor, reversing the removal procedure. B. THERMOSTAT 1. Remove the two screws securing the thermostat to the front panel. 2.
E. HIGH PRESSURE CONTROL 1. Follow the first two steps in "D". 2. Remove two screws that retain switch to right side panel. 3. Disconnect wire leads from compressor contactor and condensate pump safety switch. 4. Install new High Pressure Control, reversing the procedure. To gain access to compressor and compressor run capacitor, remove left hand side panel. TROUBLESHOOTING GUIDE The following steps and procedures are recommended for correcting the problems indicated.
2. (CAUSE) Thermostat (REMEDY) Examine the control unit for loose wires. Tighten any loose connections. Wait 4-minutes before re-start. 3. (REASON) High Pressure Control cutting (turning) unit off (FIXING) Check for loose wire connections, broken or burned contacts. If switch is defective, replace. 4. (CAUSE) Defective Power Module. (CURE) Replace 5. (REASON) Refrigerant leak-no freon. (REMEDY) Locate leak and repair. Evacuate unit and recharge. 6. (CAUSE) Loose or defective wires.
PROBLEM: INSUFFICIENT COOLING 1. (CAUSE) Insufficient air flow through evaporator coil due to: A. Dirty air filter in unit B. Dirty evaporator coil C. Ice on evaporator coil D. Obstructed air intake (REMEDY) Correct as noted: A. Clean filter (see "Preventive Maintenance" section of this manual) B. Clean filter with a vacuum cleaner & hose. C. Defrost; turn on fan only. D. Remove obstruction 2. (REASON) IMPROPER SIZING OF UNIT (FIXING) Check to make sure unit is properly sized for load.
PROBLEM: WATER LEAKING FROM PAN 1. (CAUSE) Leaky drain pan (REMEDY) Locate leak and repair pan. 2. (CAUSE) Loose evaporator, drain or condensate pump hose (REMEDY) Tighten connections. 3. (CAUSE) Defective condensate pump or excessive lift on pump (REMEDY) Examine to see if elevation exceeds 20 ft. (if it does, a larger pump will be required). Otherwise, change pump if defective. Pump will operate properly against 20 ft. of water total head pressure on pump.
2. FILTER A clogged filter will cause the unit to operate at greatly reduced efficiencies. We recommend that the filter be inspected on a regular bases every six weeks or more often depending on the environment. The throw away filter is located behind the return air grille and can be easily removed by pulling the grille out. 3. CONDENSATE PUMP When servicing pump follow these steps; 1. Make certain that the unit is disconnected from the power source before attempting to service or remove any component. 2.
