Precautions when making knockout holes:
▪ Avoid damaging the casing and underlying piping.
▪ After making the knockout holes, we recommend to
remove the burrs and paint the edges and areas
around the edges using repair paint to prevent rusting.
▪ When passing electrical wiring through the knockout
holes, wrap the wiring with protective tape to prevent
damage.

▪ Insulate the liquid piping (a) and the gas piping (b).
▪ Wind heat insulation around the curves, and then cover it
with vinyl tape (c).

7 If the outdoor unit is installed above the indoor unit, cover the
stop valves (f, see above) with sealing material to prevent
condensed water on the stop valves from moving to the indoor
unit.

NOTICE
Do not block the air vents. This could affect air circulation
inside the unit.
WARNING
Provide adequate measures to prevent that the unit can be
used as a shelter by small animals. Small animals that
make contact with electrical parts can cause malfunctions,
smoke or fire.
NOTICE
Make sure to open the stop valves after installing the
refrigerant piping and performing vacuum drying. Running
the system with the stop valves closed may break the
compressor.
