• Do not insert this hose into sewage hose or cleaning hose
that may generate ammonia gas sulfuric gas etc.
• If necessary, use hose clamp to further tighten the hose at
drain hose connector to prevent it leakage.
• The water may drip from drain hose. Therefore must ensure
the outlet of the hose is always not closed or blocked.

11.3.4. CONNECT THE CABLE TO THE INDOOR UNIT

1. Connecting cable between indoor unit and outdoor unit shall be approved polychloroprene sheathed 4 × 4.0 or 6.0 mm
flexible cord, type designation 60245 IEC 57 or heavier cord.
• Ensure the colour of wires of outdoor unit and the terminal Nos. are the same to the indoor unit's respectively.
• Earth wire shall be longer than the other wires as shown in the figure for the electrical safety in case of the slipping out of the
cord from the Holder (Clamper).
2. Cable connection to the power supply through isolating device (Disconnecting means).
• Isolating device (Disconnecting means) should have minimum 3.0 mm contact gap.
• Connect the approved polychloroprene sheathed power supply 1 cord (3 × 4.0 or 6.0 mm
2
mm ) and type designation 60245 IEC 57 or heavier cord to the terminal board, and to the other end of the cord to isolating
device (Disconnecting means).
3. To avoid cable and cord harmed by sharp edge, cable and cord must go through bushing (located at the bottom of indoor unit)
before carry out electrical connection. The bushing must be used and must not take off.
Connecting with external device (optional)
1. All connections shall follow to the local national wiring standard.
2. It is strongly recommended to use manufacturer-recommended parts and accessories for installation.
