Drain elbow and hose installation
•
Fix the drain elbow 2 and packing 3 to the bottom of indoor unit,
as shown in below illustration.
•
Use inner diameter 17 mm drain hose in the market.
•
This hose must to be installed in a continuosly downward direction
and in a frost-free environment.
•
Guides this hose's outlet to outdoor only.
•
Do not insert this hose into sewage or drain pipe that may generate
ammonia gas, sulfuric gas, etc.
•
If necessary, use hose clamp to further tighten the hose at drain
hose connector to prevent leakage.
•
Water will drip from this hose, therefore the outlet of this hose must
be installed in an area where the outlet cannot become blocked.

•
Connect a drain hose to the pressure relief valve hose outlet.
•
This hose must to be installed in a continuosly downward direction
and in a frost-free environment.
•
Guides this hose's outlet to outdoor only.
•
Do not insert this hose into sewage hose or cleaning hose that may
generate ammonia gas, sulfuric gas, etc.

CONNECT THE CABLE TO
THE INDOOR UNIT
This section is for authorised and licensed electrician only. Work
behind the Control Board Cover 6 secured by screws must
only be carried out under supervision of qualified contractor,
installation engineer or service person.
Open the Control Board Cover 6
Please follow the steps below to open control board cover. Before
Copper
pipe
opening the control board cover of indoor unit, always switch off all
power supply (i.e. indoor unit power supply, heater power supply
and Tank Unit power supply).
1. Remove the 6 mounting screws at the control board cover.
2. Swing the control board cover to the right hand side.
Fixing of Power Supply Cord and Connecting Cable
1. Connecting cable between Indoor Unit and Outdoor Unit shall
be approved polychloroprene sheathed 6 x min 1.5 mm
cord, type designation 60245 IEC 57 or heavier cord.
•
Ensure the colour of wires of Outdoor Unit and the terminal
no. are the same to the Indoor Unit respectively.
•
Earth wire shall be longer than 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. An isolating device must be connected to the power supply
cable.
•
Isolating device (disconnecting means) should have minimum
3.0 mm contact gap.
•
Connect the approved polychloroprene sheathed power
supply 1 cord and power supply 2 cord 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). See below table for cable size requirement.
