WARNING
1. Safety Precautions
Read the following “SAFETY PRECAUTIONS” carefully before perform any servicing.
Electrical work must be installed or serviced by a licensed electrician. Be sure to use the correct rating and main
circuit for the model installed.
The caution items stated here must be followed because these important contents are related to safety. The
meaning of each indication used is as below. Incorrect installation or servicing due to ignoring of the instruction
will cause harm or damage, and the seriousness is classified by the following indications.
This indication shows the possibility of causing death or serious injury.
This indication shows the possibility of causing injury or damage to properties.
The items to be followed are classified by the symbols:
Carry out test run to confirm that no abnormality occurs after the servicing. Then, explain to user the operation,
care and maintenance as stated in instructions. Please remind the customer to keep the operating instructions for
future reference.
1. Do not use unspecified cord, modified cord, joint cord or extension cord for power supply cord. Do not share the single outlet with other
electrical appliances. Poor contact, poor insulation or over current will cause electrical shock or fire.
2. Do not install outdoor unit near handrail of veranda. When installing outdoor unit at veranda of high rise building, child may climb up to
outdoor unit and cross over the handrail and causing accident.
3. Do not tie up the power supply cord into a bundle by band. Abnormal temperature rise on power supply cord may happen.
4. Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.
(For Outdoor Unit)
5. Do not sit or step on the unit, you may fall down accidentally.
(For Outdoor Unit)
6. Keep plastic bag (packaging material) away from small children, it may cling to nose and mouth and prevent breathing.
7. Do not use pipe wrench to install refrigerant piping. It might deform the piping and cause the unit to malfunction.
8. Do not purchase unauthorized electrical parts for installation, service, maintenance and etc.. They might cause electrical shock or fire.
9. Do not modify the wiring of outdoor unit for installation of other components (i.e. heater, etc.). Overloaded wiring or wire connection
points may cause electrical shock or fire. (For Outdoor Unit)
10. Do not add or replace refrigerant other than specified type. It may cause product damage, burst and injury etc.
11. Do not use the hot water produced by the Tank Unit for drinking or food preparation. It may cause illness to the user.
12. Do not place containers with liquids on top of the Tank Unit. It may cause Tank Unit damage and/or fire could occurs if they leak or
spill onto the Tank Unit.
13. For electrical work, follow local wiring standard, regulation and this installation instruction. An independent circuit and single outlet must be
used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock or fire.
14. For water circuit installation work, follow to relevant European and national regulations (including EN61770) and local plumbing and building
regulation codes. (For Tank Unit)
15. Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, electrical shock or fire.
16. • This is a R410A model, when connecting the piping, do not use any existing (R22) pipes and flare nuts. Using such same may cause
abnormally high pressure in the refrigeration cycle (piping), and possibly result in explosion and injury. Use only R410A refrigerant.
• Thickness or copper pipes used with R410A must be 0.8 mm or more. Never use copper pipes thinner than 0.8 mm.
• It is desirable that the amount of residual oil is less than 40 mg/10 m.
17. When install or relocate Tank Unit / Outdoor Unit, do not let any substance other than the specified 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.
18. Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fire.
19. Install at a strong and firm 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.
20. Do not use joint cable for Tank Unit / Outdoor Unit connection cable. Use specified Tank Unit / Outdoor Unit connection cable, refer to
instruction
CONNECT THE CABLE TO THE TANK UNIT / CONNECT THE CABLE TO THE OUTDOOR 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 fixing is not
perfect, it will cause heat up or fire at the connection.
21. This equipment is strongly recommended to be installed with Residual Current Device (RCD) on-site according to the respective national
wiring rules or country–specific safety measures in terms of residual current. (For Tank Unit)
22. During installation, install the refrigerant piping properly before run the compressor. Operation of compressor without fixing 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.
23. 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.
This symbol denotes item that is PROHIBITED from doing.
