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 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
℃
Compressor: Compresses the vapor refrigerant sucked from the evaporator and discharges it to condenser
℃
Condenser: Changes the compressed vapor refrigerant into the liquid refrigerant by cooling.
℃
Drier: Removes moisture and dirt inside pipes
℃
Capillary tube: Reduces the pressure of liquid refrigerant and evaporates it in the evaporator under
constant pressure.
℃
Evaporator: Absorbs the surrounding heats while evaporating the liquid refrigerant, cools down water inside
of cold water tank.
℃
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.
℃
Over Load Protector (OLP): Protects the compressor and operates when rising up to abnormal temperature
or energizing over current.
℃
PTC Starter: Starts up the motor of compressor.
℃
Cold water baffle: Separates the supplied water from cold water, hot water, or room temperature water
respectively.
℃
Hot tank heater: Heats the supplied room temperature water to hot water.
℃
Hot control: Controls the temperature of hot water at a proper automatically.
℃
Heat limiter: Cuts off the electric power to the heater in case of overheating.
℃
Hot water switch: Supplies or cuts off the electric power to the heater by setting it ON/OFF.
℃
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.
