• After the refrigerant piping and electrical wiring work is completed, hold the refrigerant piping, the
indoor unit drain hose, the wiring connecting the indoor and outdoor units and the earth wire with the
piping retainer plate (Refer to Fig. 12). During this work the refrigerant piping entering into the indoor
unit may come in contact with the suction grille. Therefore, make sure not to extend the refrigerant
piping from the piping retainer plate.
(For electrical wiring work, see “8. ELECTRIC WIRING WORK”.)
• After leakage check of piping connection is finished, carry out thermal insulation. (Refer to Fig. 13)
• Carry out thermal insulation of both liquid and gas pipes with the attached insulation for fitting (5) and
(6). (Tighten both ends of the insulation for fitting (5) and (6) with the clamp (8).
Be sure to insulate any field piping all the way to the piping connection inside the unit.
Any exposed piping may cause condensation or burns if touched, and also electrical shock or fire if the
wiring is touched.
• CAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT PIPING
• Do not braze inside the unit.
Since the bottom plate and the fan housing are made of resin. They may melt or cause fire by spatter.
