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
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

2. OPERATION & FUNCTION OF PARTS
5
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
The electric heater inside of the hot water tank heats the supplied water. The temperature of hot
6
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
①
Compressor: Compresses the vapor refrigerant sucked from the evaporator and discharges it to
condenser
②
Condenser: Changes the compressed vapor refrigerant into the liquid refrigerant by cooling.
③
Drier: Removes moisture and dirt inside pipes
④
Capillary tube: Reduces the pressure of liquid refrigerant and evaporates it in the evaporator
under constant pressure.
⑤
Evaporator: Absorbs the surrounding heats while evaporating the liquid refrigerant, cools down
water inside of cold water tank.
⑥
Cold 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.
⑦
Over Load Protector (OLP): Protects the compressor and operates when rising up to abnormal
temperature or energizing over current.
⑧
PTC Starter: Starts up the motor of compressor.
⑨
Cold water baffle: Separates the supplied water from cold water, hot water, or room temperature
water respectively.
⑩
Hot tank heater: Heats the supplied room temperature water to hot water.
⑪
Hot control: Controls the temperature of hot water at a proper automatically.
⑫
Heat limiter: Cuts off the electric power to the heater in case of overheating.
⑬
Hot water switch: Supplies or cuts off the electric power to the heater by setting it ON/OFF.
⑭
Drain 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.
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.
4. INSTALLATION PROCEDURES
A.
Install drip tray below faucet.
B.
Thoroughly clean the cooling tank and baffle. Baffle must be in exact place for proper cooling
operation.
CAUTION: IF THE COLD WATER BAFFLE IS REMOVED, COLD WATER WILL NOT BE FORMED NOR
7
DISCHARGED.
C.
Put standardized bottle filled with water on top of the product.
Use drinking water only. Filling the unit with any other type of beverages may cause significant
problems.
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.)
CAUTION: FAILURE TO FILL HOT TANK WITH WATER BEFORE SWITCH ON HOT WATER CAN CAUSE
PHYSICAL DAMAGE TO THE COOLER.
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.
5. STORAGE
A.
Switch off hot water switch. Unplug power cord.
B.
Drain hot water by opening faucet. Then, do the same on cold water faucet.
C.
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 the end of drain
pipe. Close draining pipe with cap.
D.
When storing, ensure it stands on its erect position on the flat and even ground. (Do not lay the
product on its sides down or upside down.)
E.
When not use for a long period of time, conduct product cleaning before you put in storage.
CAUTION: FAILURE TO ABIDE BY ABOVE PROCEDURE MAY INCUR PHYSICAL DAMAGE ON THE
COOLER.
CAUTION: WATER FROM HOT FAUCET IS EXTREMELY HOT AND MAY SCALD.
