CHECK THE DRAINGAGE
Check after connecting the power supply.
• Pour approximately 600 cc of water into the drain pan of the main unit using a squeeze bottle, etc.
• Press the drain test run switch on the control board in the control box to start the drain motor and check whether the
water drains normally. (The drain motor operates for approximately 5 minutes and then stops automatically.) (See the
diagram for "Connecting the Indoor/Outdoor Connecting Cable".)
11.2.5. INSULATING THE REFRIGERANT PIPING
• After the piping is connected, insulate as shown in the illustration.
11.2.6. CONNECTING THE INDOOR/OUTDOOR CONNECTING CABLE
• Remove the control box cover and lead the connecting
cable into the control box.
• Check the color of the wires on the terminal board and
secure them with screws.
• Secure the outer sheath of the connecting cable with the
cord clamp.
• Reattach the control box cover to its original position.
CAUTION
When connecting the connecting cable, provide approximately
40 cm of extra length near the unit to facilitate servicing of
electrical parts.
• Connecting cable between indoor unit and outdoor unit
should be approved polychloroprene sheathed 4 x 1.5 mm
flexible cord, designation type 245 IEC 57 (H05RN-F) or
heavier cord.
− Ensure that the terminal numbers on the indoor unit are
connected to the same terminal numbers on the outdoor
unit by the right coloured wires as shown in the diagram.
− Earth lead wire should be longer than the other lead
wires as shown in the diagram for electrical safety
purpose in case the cord slips out from the anchorage.
• Secure the cable onto the control board with the holder (clamper).
