Precautions for installation of domestic hot water tank
Warning
Installation
Mandatory
Check leakage of the tank itself before installation if existing tank is used.
Be careful not to let your body touch the heating pipe directly.
(It may cause a burn.)
An expansion tank with insufcient capacity may provide poor heating performance.
The structure should be able to withstand the tank load when installing the boiler.
(including the load of water in the tank)
The domestic hot water tank should be level.
Piping should be arranged horizontal or vertical simply and accurately.
Do not allow foreign substances to enter the domestic hot water tank
Do not use eye bolts for transportation as materials for piping connection.
Clean the pipes before starting the plumbing work.
Make sure the sizes of the hot water suppy and return piping are identical.
If the room to be heated is located higher than the domestic hot water tank, use
a circulation pump with a check valve or a lifting check valve to prevent natural
convection.
As the maximum use pressure of the domestic hot water tank is 1kgf/㎠, the
expansin tank may be installed at elevations up to 10m.
Insulation should be applied to all exposed pipes to prevent freezing and bursting and heat loss.
(Without heat retaining treatment, damages to the insulation, electric short or freezing and
bursting may occur by dew condensation, which may result in human or property damages.)

Precautions for installation of domestic hot water tank
Warning
Installation
Make sure there is no leakage on piping or overow from the expansion tank.
(Pipe leakage or overow of expansion tank may cause the supply of dissolved
oxygen, which will accelerate the corrosion of pipe.)
Relling water in the domestic hot water tank should be carried out through the
expansion tank.
You must put anticorrosive agent to prevent the corrosion of domestic hot water
tank and pipes.
Make sure the domestic hot water tank is grounded.
Use a professional service provider when disposing of the boiler after replacement.
(Illegal or arbitrary disposal may cause safety accidents, injuring the elderly or
children)
You must install a water softener when using groundwater with minerals, such
as limestone or calcium, or when using saline water near the beach.
(Failure to do so may cause or accelerate a corrosion of the product or its parts.)

When using anticorrosive agent, please observe the following:
How to use anticorrosive agent
①Do not mix with oxidizing agent.
②Keep away from heat, flame, spark or other ignition sources.
③A person who is not aware of the hazardousness of anticorrosive agent must not
handle or distribute anticorrosive agent.
④Keep out of reach of children or the elderly.
⑤Do not use the empty container of anticorrosive agent for other purposes.
⑥ Dispose of or return the empty container or vessel of anticorrosive agent to your
nearest dealer.
⑦Rinse the empty container 3 times or more with water.
⑧Be careful not to inhale, consume or allow your eyes or body to come into contact with
anticorrosive agent as it has hazardous and dangerous characteristics as specified in
the Article 41 of the Industrial Safety and Health Act.
①After installing the boiler, shake and fill the anticorrosive agent into the boiler before
filling water.
②Rinse the anticorrosive agent container with water.
③The use life of anticorrosive agent is 1 year (refill it once a year).
④Fill anticorrosive agent after installing the domestic hot water tank. When refilling
anticorrosive agent, close the water supply valve and open the drainage valve to
discharge the water in the tank, fill anticorrosive agent and then open the water supply
valve to fill with water.
①You must call the authorized service center or a professional installation agency for
installation.
- Poor installation may cause a fire, electric shock, explosion or damage.
②Contact the authorized service center or a professional installation agency to reinstall
the installed product.
- Poor installation may cause a fire, electric shock, explosion or damage.
③Do not disassemble, repair or modify the product arbitrarily.
- This may cause a fire or electric shock.

Domestic hot water tank
● The domestic hot water tank stores thermal heat generated by heat pump.
Expansion tank
● The expansion tank is a device that absorbs the volume expansion of water
consistent with the increase of water temperature.
● Valves should not be used when installing an expansion tank, and insulation
should be provided to prevent freezing and bursting.
Freeze and burst protection
● When the flow temperature goes below 6℃, the circulation pump (heating
pump, domestic hot water pump) is automatically activated and circulates
water in the piping to prevent damage to the boiler caused by freezing.

is as follows:
Ambient temperature of the outdoor unit: -20
℃
~ 40
℃
Ambient temperature of the hydro unit 5
℃
~ 40
℃
environment out of the temperature limits for a long 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)
Heating features
● A warm-up time is required prior to the start of heating operation when the outdoor
temperature is 10℃or below.
● 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 is completely defrosted, the heating operation is put back
on track automatically.
Power outage recovery function
● When the power is cut during operation, the product recalls the most recent operating
conditions and automatically applies these 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.
Minimum operating time
● It takes 7 minutes for the compressor to stop its operation once it is activated in a
normal condition.
