When install or relocate Tank Unit, do not let any substance other than the speciﬁ ed refrigerant, eg. air etc mix into refrigerant cycle (piping). Mixing of air etc. will

cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.

Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or ﬁ re.

Install at a strong and ﬁ rm location which is able to withstand the set's weight. If the strength is not enough or installation is not properly done, the set will drop

and cause injury.

This equipment is strongly recommended to be installed with Residual Current Device (RCD) on-site according to the respective national wiring rules or country–

speciﬁ c safety measures in terms of residual current.

During installation, install the refrigerant piping properly before run the compressor. Operation of compressor without ﬁ xing refrigeration piping and valves at

opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc.

During pump down operation, stop the compressor before remove the refrigeration piping. Removal of refrigerant piping while compressor is operating and valves

are opened will cause suck-in of air, abnormal high pressure in refrigerant cycle and result in explosion, injury etc.

Tighten the ﬂ are nut with torque wrench according to speciﬁ ed method. If the ﬂ are nut is over tightened, after a long period, the ﬂ are may break and cause

refrigerant gas leakage.

After completion of installation, conﬁ rm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant contacts with ﬁ re.

Ventilate the room if there is refrigerant gas leakage during operation. Extinguish all ﬁ re sources if present. It may cause toxic gas when the refrigerant contacts

with ﬁ re.

Only use the supplied or speciﬁ ed installation parts, else, it may causes unit vibrate loose, water leakage, electrical shock or ﬁ re.

If there is any doubt about the installation procedure or operation, always contact the authorized dealer for advice and information.

Select a location where in case of water leakage, the leakage will not cause damage to other properties.

When installing electrical equipment at wooden building of metal lath or wire lath, in accordance with electrical facility standard, no electrical contact between

equipment and building is allowed. Insulator must be installed in between.

Any work carried out on the Tank Unit after removing any panels which is secured by screws, must be carried out under the supervision of authorized dealer and

licensed installation contractor.

This system is multi supply appliance. All circuits must be disconnected before accessing the unit terminals.

For cold water supply has a backﬂ ow regulator, check valve or water meter with check valve, provisions for thermal expansion of water in the hot water system

must be provided. Otherwise it will cause water leakage.

The piping installation work must be ﬂ ushed before Tank Unit is connected to remove contaminants. Contaminants may damage the Tank Unit components.

This installation may be subjected to building regulation approval applicable to respective country that may require to notify the local authority before installation.

The Tank Unit must be shipped and stored in upright condition and dry environment. It may laid on its back when being moved into the building.

Work done to the Tank Unit after remove the front plate cover that secured by screws, must be carried out under the supervision of authorized dealer, licensed

installation contractor, skilled person and instructed person.

This unit must be properly earthed. The electrical earth must not be connected to a gas pipe, water pipe, the earth of lightening rod or a telephone. Otherwise

there is a danger of electrical shock in the event of an insulation breakdown or electrical earth fault in the Tank Unit.

Do not install the Tank Unit at place where leakage of ﬂ ammable gas may occur. In case gas leaks and accumulates at surrounding of the unit, it may cause ﬁ re.

Do not release refrigerant during piping work for installation, re-installation and during repairing a refrigeration parts. Take care of the liquid refrigerant, it may

cause frostbite.

Do not install this appliance in a laundry room or other high humidity location. This condition will cause rust and damage to the unit.

Make sure the insulation of power supply cord does not contact hot part (i.e. refrigerant piping, water piping) to prevent from insulation failure (melt).

Do not apply excessive force to water pipes that may damage the pipes. If water leakage occurs, it will cause ﬂ ooding and damage to other properties.

Do not transport the Tank Unit with water inside the unit. It may cause damage to the unit.

Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the furniture.

Select an installation location which is easy for maintenance.

Power supply connection to Tank Unit.

•

Power supply point should be in easily accessible place for power disconnection in case of emergency.

•

Must follow local national wiring standard, regulation and this installation instruction.

•

Strongly recommended to make permanent connection to a circuit breaker.

- Power Supply 1: Use approved 20A 4-poles circuit breaker with a minimum contact gap of 3.0mm.

- Power Supply 2: Use approved 20A 4-poles circuit breaker with a minimum contact gap of 3.0mm.

Ensure the correct polarity is maintained throughout all wiring. Otherwise, it will cause electrical shock or ﬁ re.

After installation, check the water leakage condition in connection area during test run. If leakage occurs, it will cause damage to other properties.

If the Tank Unit not operates for long time, the water inside the Tank Unit should be drained.

Installation work.

It may need three or more people to carry out the installation work. The weight of Tank Unit might cause injury if carried by one person.
