10. Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.
11. Do not sit or step on the unit, you may fall down accidentally.
12.
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.
13.
For water circuit installation work, follow to relevant European and national regulations (including EN61770) and local plumbing and
building regulation codes.
14.
Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, electrical shock or
fire.

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
15.
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 40mg/10m.
16.
When install or relocate Indoor Unit / Outdoor Unit, do not let any substance other than the specified refrigerant, e.g. 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..
17. Install according to this installation instruction strictly. If installation is defective, it will cause water leakage, electrical shock or fire.
18.
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.
19.
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.
During installation, install the refrigerant piping properly before run the compressor. Operation of compressor without fixing
20. 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
21. 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.
22.
Tighten the flare nut with torque wrench according to specified method. If the flare nut is over tightened, after a long period, the flare
may break and cause refrigerant gas leakage.
23.
After completion of installation, confirm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant contacts
with fire.
24.
Ventilate the room if there is refrigerant gas leakage during operation. Extinguish all fire sources if present. It may cause toxic gas
when the refrigerant contacts with fire.
25. Only use the supplied or specified installation parts, else, it may cause unit vibrate loose, water leakage, electrical shock or fire.
26.
The unit is only for use in closed water system. Utilization in an open water circuit may lead to excessive corrosion of water piping and
risk of incubating bacteria colonies, particularly Legionella, in water.
27. If there is any doubt about the installation procedure or operation, always contact the authorized dealer for advice and information.
28. Select a location where in case of water leakage, the leakage will not cause damage to other properties.
29.
When installing electrical equipment at wooden building of metal lath or wire lath, in accordance with electrical facility standard, no
