FOR YOUR SAFETY
Please read the following safety precaution before servicing the watercooler.
1) Check if an electric leakage occurs in the appliance.
2) To prevent electric shock, unplug prior to servicing.
3) In case of testing with power on, wear rubber gloves to prevent electric shock.
4) When using an instrument or replacing a part for repairing, check it is applied to rated voltage
current and capacity.
5) Prevent water from flowing into electric elements in mechanical parts.
6) When carrying or tilting the appliance, remove all the objects on it.
7) If the cooling cycle is out of order, contact nearest authorized service center for maintenance,

2. OPERATION & FUNCTION OF PARTS
A. Cooling Operation
The vapor refrigerants that compressed to high temperature & high pressure conditions in the compressor, turn
into liquid refrigerant of high temperature and high pressure passing through the condenser, and then turn into
the liquid refrigerants of low temperature and low pressure conditions by passing through the capillary tubes.
The liquid refrigerant of low temperature & low pressure absorbs the surrounding heat while evaporating in the
evaporator. Then, it is sucked in the compressor by turning into saturated vapor.
B. Heating Operation

Updated on 18 March, 2010
- 5 -
The electric heater inside of the hot water tank heats the supplied water. The temperature of hot water is
controlled by the hot control at a proper temperature. In case of overheating, the heat limiter will operate
automatically.
C. Function of Parts
①Compressor: Compresses the vapor refrigerant sucked from the evaporator and discharges it to condenser
②Condenser: Changes the compressed vapor refrigerant into the liquid refrigerant by cooling.
③Drier: Removes moisture and dirt inside pipes
④Capillary tube: Reduces the pressure of liquid refrigerant and evaporates it in the evaporator under
constant pressure.
⑤Evaporator: Absorbs the surrounding heats while evaporating the liquid refrigerant, cools down water inside
of cold water tank.
⑥Cold water thermostat: Senses the temperature of cold water tank and controls the electric power supply to
the compressor automatically in order to keep the constant temperature of cold water.
⑦Over Load Protector (OLP): Protects the compressor and operates when rising up to abnormal temperature
or energizing over current.
⑧PTC Starter: Starts up the motor of compressor.
⑨Cold water baffle: Separates the supplied water from cold water, hot water, or room temperature water
respectively.
⑩Hot tank heater: Heats the supplied room temperature water to hot water.
⑪Hot control: Controls the temperature of hot water at a proper automatically.
⑫Heat limiter: Cuts off the electric power to the heater in case of overheating.
⑬Hot water switch: Supplies or cuts off the electric power to the heater by setting it ON/OFF.
⑭Drain cap: By opening this, you may drain out remaining water in hot water tank when cleaning or not using
cooler for a long period of time.
⑮Dual float valve assembly: Controls the water level of cold water tank. When the primary valve malfunctions,
secondary float activates and close the water inflows, preventing damage caused by water leakage.
3. LOCATION REQUIREMENTS
A. Locate cooler in a well ventilated space where temperature is never below 0℃.
B. Maintain a minimum clearance of 4 inches on sides and rear of cooler for proper ventilation.
C. Make sure installation ground is flat and even. - Unbalanced placement may cause excessive noise and
trembling of the cooler.
D. Coolers are for indoor use only. Keep away from direct sunlight and excessive moisture.
E. Avoid harmful gas or excessive heat.

exact place for proper cooling operation.
CAUTION: IF THE COLD WATER BAFFLE IS REMOVED, COLD WATER WILL NOT BE FORMED NOR DISCHARGED.
C. Connect the supply water hose to cold water piping of the
back of the product.
-Connect the supply water pipe to water inlet at the back
of the product.
-Use potable water only.
-Acceptable supply water pressure is 20 ~ 100psi.
-Press reset button if cold water does not flow.
-Once all the requirements above are met, open the tap
water valve.
CAUTION: TO PREVENT PROPERTY DAMAGE DUE TO WATER LEAKAGE, SEEK INSPECTION BY PLUMBERS TO
SEE THE WATER PRESSURE IS LESS THAN 100PSI (690KPA) BEFORE YOU CONNECT THE SUPPLY WATER
HOSE.
D. For hot water activation, stay holding down hot faucet handle until water flow is continuous and clear.
E. Place the hot water switch on the "ON" position.
(Check the available power supply against the cooler specification plate to ensure correct electrical service.)
F. Cooler will be ready to serve you Cold & Hot water in 30 minute after installation.
G. Hot Water Safety Faucet: A safety faucet deters accidental dispensing of water by toddlers. (Korea, US
patented)
CAUTION: WATER FROM HOT FAUCET IS EXTREMELY HOT AND MAY SCALD.
CAUTION: FAILURE TO ABIDE BY ABOVE PROCEDURE CAN CAUSE PHYSICAL DAMAGE ON THE COOLER.
5. STORAGE
A. Close off the adapter valve to cut flow from main water pipe.
B. Switch off hot water switch.
C. Unplug power cord.
D. Disconnect the water pipe from the product.
E. Drain hot water by opening faucet. Then, do the same on cold water faucet.
F. Place a bucket behind the drain pipe. By unscrewing the drain cap counter clockwise, drain the remaining
water in the hot water tank. When tank is emptied, dry drain cap and end of drain pipe. Close draining pipe
with cap.
