Do not add or replace refrigerant other than specifi ed type. It may cause product damage, burst and injury etc.
Do not place containers with liquids on top of the Tank Unit. It may cause Tank Unit damage and/or fi re could occurs if they leak or spill onto the
Tank Unit.
Do not use joint cable for Tank Unit / Outdoor Unit connection cable. Use specifi ed Tank Unit / Outdoor Unit connection cable, refer to instruction
4
CONNECT THE CABLE TO THE TANK UNIT
and connect tightly for Tank Unit / Outdoor Unit connection. Clamp the cable so that no external
force will be acted on the terminal. If connection or fi xing is not perfect, it will cause heat up or fi re at the connection.
For electrical work, follow the national regulation, legislation and this installation instructions. An independent circuit and single outlet must be
used. If electrical circuit capacity is not enough or defect found in the electrical work, it will cause electrical shock or fi re.
For water circuit installation work, follow to relevant European and national regulations (including EN61770) and local plumbing and building
regulation codes.
Engage authorized dealer or specialist for installation. If installation done by the user is incorrect, it will cause water leakage, electrical shock
or fi re.
Install at a strong and fi rm location which is able to withstand weight of the set. 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.
Use the attached accessories parts and specifi ed parts for installation. Otherwise, it will cause the set to fall, water leakage, fi re or electrical shock.
Only use the supplied or specifi ed installation parts. Else, it may causes unit vibrate, fall, water leakage, electrical shock or fi re.
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.
Be aware that refrigerants may not contain an odour.
This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod and telephone.
Otherwise, it may cause electrical shock in case of equipment breakdown or insulation breakdown.
CAUTION
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.
Prevent liquid or vapor from entering sumps or sewers since vapor is heavier than air and may form suffocating atmospheres.
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. 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.
Incorrect installation, service or repair of this Tank Unit may increase the risk of rupture and this may result in loss damage or injury and/or
property.
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.

For Tank Unit WH-ADC0509L3E5 and WH-ADC0509L3E5AN:
-
Power Supply 1: Use approved 25A 2-poles circuit breaker with a minimum contact gap of 3.0mm.
-
Power Supply 2: Use approved 15/16A 2-poles circuit breaker with a minimum contact gap of 3.0mm.

For Tank Unit WH-ADC0509L6E5 and WH-ADC0509L6E5AN:
-
Power Supply 1: Use approved 25A 2-poles circuit breaker with a minimum contact gap of 3.0mm.
-
Power Supply 2: Use approved 30A 2-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.
