5-2 Install the indoor unit. (Refer to Fig. 18)
• Lock the unit to the hangers on side A.
• Hook the unit onto the other 2 hangers and lock with bottom
washers and nuts.
5-3 Check whether the unit is level from sides C
and D both. (Refer to Fig. 19)
5-4 Remove the washer fixing plate (5) used for
preventing the washer from falling and tighten
the upper nut.
CAUTION
• Do not hold the swing flap when mounting, as this may
break it.
• The indoor unit is equipped with a built-in drain pump and
float switch. At each of the unit’s 4 corners, verify that it is
level by using a water level or a waterfilled vinyl tube.
(If the unit is tilted against condensate flow, the float switch
may malfunction and cause water to drip.)
6. REFRIGERANT PIPING WORK
〈
For refrigerant piping of outdoor and BEV units, see the
installation manual attached to the outdoor and BEV units.
〉
〈Execute heat insulation work completely on both sides of
the gas piping and the liquid piping.
Otherwise, a water leakage can result sometimes.〉
〈When using a heat pump, the temperature of the gas pip-
ing can reach up to approximately 120°C, so use insulation
which is sufficiently resistant.〉
〈Improve the insulation on the refrigerant piping depend-
ing on the installation environment.
If the insulation is not sufficient, condensation may form
on the surface of the insulation.〉
〈Before refrigerant piping work, check which type of refrig-
erant is used. Proper operation is not possible if the types
of refrigerant are not the same.〉
CAUTION
• Use a pipe cutter and flare suitable for the type of refrig-
erant.
• Apply ester oil or ether oil around the flare section
before connecting.
• To prevent dust, moisture or other foreign matter from
infiltrating the tube, either pinch the end or cover it with
tape.
• Do not allow anything other than the designated refrig-
erant to get mixed into the refrigerant circuit, such as
air, etc. If any refrigerant gas leaks while working on the
unit, ventilate the room thoroughly right away.
6-1 Refrigerant piping can be run in 3 directions
(Refer to Fig. 20)
• Use copper alloy seamless piping (ISO 1337).
• The outdoor unit is charged with refrigerant.
• Be sure to use both a spanner and torque wrench together,
when connecting or disconnecting piping to/from the unit.
(Refer to Fig. 21)
• Refer to the Table 2 for flare dimensions and tightening torque.
NOTE
• Use the flare nut included with the unit main body.
CAUTION
• Over-tightening the flare nut may break it and/or cause the
refrigerant to leak.
• When connecting the flare nut,
apply ester oil or ether oil to
the flare section (both inside
and outside), and spin 3-4
times before screwing in.
