Remove the Valve cover from the unit by loosening the screw.
Align the center of the pipings and sufficiently tighten the flare
nut by hand.
Finally, tighten the flare nut with torque wrench until the wrench
clicks.
2.Overlap the connection pipe insulation material and the indoor
unit pipe insulation material. Bind them together with vinyl tape
so that there is no gap.
After the piping has been connected to the indoor unit, perform
the air purge.
Air purging with vacuum pump
Be sure to use a vacuum pump with counter-flow prevention
function so that oil inside the pump does not flow back into the
air conditioner pipes when the pump stops. (If oil inside the
vacuum pump enters into the air conditioner circuit which uses
R410A, trouble with the refrigeration system may develop.)
2) Swing the indoor unit to right and left to confirm that it is firmly
hooked on the installation plate.
3)While pressing the indoor unit onto the wall, hook it at the lower
part on the installation plate.
Pull the indoor unit toward you to confirm that it is firmly
hooked on the installation plate.
For detaching the indoor unit from the installation plate pull the
indoor unit toward you while pushing the bottom up at the
specified places.
4)Run the drain hose at a downward sloped angle.
5)Put water in the drain pan and make sure that the water is
being drained outside.
Caution:
Install the drain pipe for proper drainage. Improper drainage can
result in water dripping inside the room.
7.4 Installation of Outdoor Unit
* Holes are provided on the base plate of the outdoor unit to
ensure that the defrost water produced during heating opera-
tions is drained off efficiently.
* If a centralized drain is required when installing the unit on a
balcony or wall.
* If the drain port is covered by a mounting base or floor surface,
place additional foot bases of at least 30mm in height under the
outdoor unit’s feet.
* In cold areas, do not use a drain hose with the outdoor unit.
(Otherwise, drain water may freeze, impairing heating
performance.)
