Drainage piping installation
Use a drain hose with inner diameter of 15 mm.
The hose must be installed in a continuously downward direction and left open to the frost-free atmosphere.
If drain hose is long, use a metal support fixture along the way to eliminate the wavy pattern of drain tube.
Water will drip from this hose, therefore the outlet of this hose must be installed in an area where the outlet
cannot become blocked.
Do not insert this hose into sewage or drain pipe that may generate ammonia gas, sulfuric gas, etc.
If necessary, use a hose clamp to tighten the hose at drain hose connector to prevent it from leaking.

11.4 Connect The Cord And Cable To Mono Bloc Unit
(REFER TO WIRING DIAGRAM AT UNIT FOR DETAIL)
1. 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 (5 × min 1.5 mm
2
) and power supply 2
cord (3 × min 1.5 mm
2
) -9kW models or (5 × min 1.5 mm
2
) -12/14/16kW models, type designation 60245 IEC 57
or heavier cord to the RCCB, and to the other end of the cord to isolating device (Disconnecting means).
2. To avoid the cable and cord being damaged by sharp edges, the cable and cord must be passed through a
bushing (located at the right hand side of the mono bloc unit) before being connected to the terminal block. The
bushing must be used and must not be removed.
3. Secure the cable onto the control board with the holder (clamper).
