Caution
When using the product
When installing a new domestic hot water tank
● Put an anticorrosive agent at the time of installation, and fill or replace the anticorrosive agent
annually.
- Failure to use an anticorrosive agent may accelerate pipe corrosion.
- Pipe corrosion may be accelerated due to the supply of dissolved oxygen resulting from
leakage on the pipe fittings, circulation pump leakage, overflow from expansion tank, even
if an anticorrosive agent is filled into the tank.
● Please make sure there is no pipe leakage, overflow from expansion tank.
- Pipe leakage, overflow from tank expansion may result in the supply of dissolved oxygen,
which will lead to acceleration of pipe corrosion.
● Use a professional service provider when disposing of the boiler after replacement.
- Illegal or arbitrary disposal may cause safety accidents, affecting the elderly or children.
Be careful not to let your skin touch the outlet of the heating section.
- It may cause a burn.
You must install a water softener when using a groundwater with minerals
such as limestone or calcium, or when using saline water near the beach.
- Failure to use soft water may cause or accelerate the corrosion of the
product or its parts.
Put or replace anticorrosive agent annually.
- Failure to use an anticorrosive agent may accelerate the pipe corrosion.
Be careful not to cause pipe leakage, overow from expansion tank.
- Pipe leakage, overow from expansion tank may result in the supply of
dissolved oxygen, which will lead to acceleration of pipe corrosion.
Use a professional service provider when disposing of the boiler after
replacement.
- Illegal or arbitrary disposal may cause safety accidents, affecting the elderly
or children.

②If the product operates in an environment out of the temperature limits for an
extended period of time, the system may detect an error and stop operation.
Time delay
● When restarting the system, the compressor starts 3 minutes after the power is restored.
(however, the time delay is 5 minutes in the event of a shutdown through self diagnosis)
Minimum operating time
● It takes 7 minutes for the compressor to stop its operation once it is activated in
normal conditions.
Heating features
● A warm-up time is required prior to the start of heating operation when the outdoor
temperature is 10℃or less.
● The heating performance may be deteriorated if the outdoor temperature is very low.
We recommend that you use an auxiliary heating source if the room temperature is
insufficient in the winter season.
Defrost operation
● If the heat exchanger of outdoor unit becomes frosted during the heating operation,
the fan of outdoor unit will stop while defrosting heat exchanger of outdoor unit.
● When the heat exchanger of outdoor unit is completely defrosted, the heating
operation is put back on track automatically.
Power outage recovery function
● When the power is cut during the operation, the product will remember the last operating
conditions and automatically apply these conditions when the power is restored.
Normal operation
● You can hear the sound of refrigerant flowing in the product when the product is in
operation or stops operation.
● The outdoor unit fan may not operate during the heating operation, which may be
observed in the defrost mode.
