CAUTION
CAUTION
An external filter (30 mesh or more, field supplied)
must be installed before the water inlet of the indoor
unit (with “WATER IN” indication).
Refer to Diagram 4.1 for pipe connection of
Radiator, Floor Heater, Tank Unit, Solar Pump
Station, 3-way Valve Kit, 2-way Valve Kit and etc.
Fail to connect the pipes appropriately might cause
the unit malfunction.
Diagram 4.1: Typical Water Piping Installation
Be sure to use two spanners to tighten the
connection. Further tighten the nuts with torque
wrench in specified torque as stated in the table.
If non-brass metallic piping is used for installation,
make sure to insulate the pipes to prevent galvanic
corrosion.
Make sure to insulate the water circuit pipes to
prevent reduction of heating capacity.
After installation, check the water leakage condition
in connection area during test run.
Finally, mount the PS foam

and long banding
strap

to water inlet and outlet connectors, as
shown in below illustration.

Do not over tighten, over tightening cause water leakage.
12.3.3.3 Indoor Unit Refrigerant Pipe
Installation
1 Please make flare after inserting flare nut
(located at joint portion of tube assembly) onto
the copper pipe. (In case of using long piping)
2 Do not use pipe wrench to open refrigerant
piping. Flare nut may be broken and cause
leakage. Use proper spanner or ring wrench.
3 Connect the piping:
o
Align the center of piping and sufficiently
tighten the flare nut with fingers.
o
Further tighten the flare nut with torque
wrench in specified torque as stated in the
table.

Do not over tighten, over tightening cause gas leakage.
12.3.3.4 Drain Hose Installation
Use inner diameter 15 mm drain hose in the market.
This hose must to be installed in a continuously
downward direction and in a frost-free environment.
Guides this hose’s outlet to outdoor only.
Do not insert this hose into sewage or drain pipe
that may generate ammonia gas, sulfuric gas, etc.
If necessary, use hose clamp to further tighten the
hose at drain hose connector to prevent leakage.
Water will drip from this hose, therefore the outlet of
this hose must be installed in an area where the
outlet cannot become blocked.
