For local insulation, be sure to insulate local piping
all the way into the pipe connections inside the unit.
Exposed piping may cause condensation or may
cause burns when touched.
Make sure that no oil remains on plastic parts of the
decoration panel (optional equipment).
Oil may cause degradation and damage to plastic
parts.

2) Be sure to insulate both the gas and liquid piping. Use
separate thermal insulation pipes for gas and liquid
refrigerant pipes. See the figure below.

Gas pipe
- Keep piping as short as possible and slope it downwards at a
gradient of at least 1/100 so that air may not remain trapped
inside the pipe.
- Keep pipe size equal to or greater than that of the connecting
pipe (PVC pipe, nominal diameter 20mm in, outside diameter
25mm).
- Push the drain hose as far as possible over the drain socket,
and tighten the metal clamp securely.
4 CONNECT THE DRAIN PIPE
- Insulate the drain hose inside the building.
- If the drain hose cannot be sufficiently set on a slope, fit the
hose with drain raising piping (field supply).

- Make sure that heat insulation work is executed on the
following 2 spots to prevent any possible water leakage due
to dew condensation.

Drainage test
- Check whether the drainpipe is unhindered.
- New built house should have this test done before paving the ceiling.
5 ELECTRIC WIRING WORK
General instructions
All field wiring and components must be installed by a licensed
electrician and must comply with relevant European and national
regulations.
Use copper wire only.
A circuit breaker capable of shutting down power supply to the
entire system must be installed.
Note that the operation will restart automatically if the main
power supply is turned off and then turned back on again.
Be sure to ground the air conditioner.
Do not connect the ground wire to gas pipes, water pipes,
lightning rods, or telephone ground wires.
- Gas pipes: might cause explosions or fire if gas leaks.
- Water pipes: no grounding effect if hard vinyl piping is used.
- Telephone ground wires or lightning rods: might cause
abnormally highelectric potential in the ground during
lightning storms .
Follow the 'Wiring diagram' attached to the unit body to wire the
outdoor unit, indoor units and the remote controller.

maximum current indicated on the nameplate which located on the side panel
of the unit. Please refer to the nameplate before selecting the cable, fuse and
switch.
