appliances. Poor contact, poor insulation or over current will cause electrical shock or fi re.

Do not tie up the power supply cord into a bundle by band. Abnormal temperature rise on power supply cord may happen.

Keep plastic bag (packaging material) away from small children, it may cause suffocation.

Do not use pipe wrench to install refrigerant piping. It might deform the piping and cause the unit to malfunction.

Do not purchase unauthorized electrical parts for installation, service, maintenance and etc.. They might cause electrical shock or fi re.

Do not modify the wiring of Indoor Unit for installation of other components (i.e. heater, etc). Overloaded wiring or wire connection points may
cause electrical shock or fi re.

Do not add or replace refrigerant other than specifi ed type. It may cause product damage, burst and injury etc.

Do not use joint cable for Indoor / Outdoor Unit connection cable. Use specifi ed Indoor / Outdoor Unit connection cable, refer to instruction 6
CONNECT THE CABLE TO THE INDOOR UNIT and connect tightly for Indoor / 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 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 fi re.

For water circuit installation work, follow to relevant European and national regulations (including EN61770) and local plumbing and building
regulation codes.

Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, electrical shock or fi re.

This is a R410A model, when connecting the piping, do not use any existing (R22) pipes and fl are 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 for copper pipes used with R410A must be 0.8mm or more. Never use copper pipes thinner than 0.8mm.

•

It is desirable that the amount of residual oil is less than 40mg/10m.

ENGLISH

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 cause unit vibrate loose, water leakage, electrical shock or fi re.

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.

EXPANSION VESSEL b PRE PRESSURE CHECKING

[Lower limit water volume of the system]
Please ensure the capacity of the circulating water of the total
system including the capacity of the indoor unit is more than 50 L.
If the water capacity is insuffi cient, during deice operation, the water
temperature is lowered and the water will freeze in the system’s
component leading to product failure.

[Upper limit water volume of the system]
The indoor unit has a build-in Expansion Vessel with 10 L air
capacity and initial pressure of 1 bar.
Total amount of water in the system should be below 260 L.
If the total amount of water is more than 260 L, please add
expansion vessel (fi eld supply).
The expansion vessel capacity required for the system can be
calculated from the formula below.

V =
