• In case of a power supply failure or pump operating failure, drain the system (as suggested in the figure below).
When water is idle inside the system, freezing up is very likely to happen which could damage the system.
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.
• The water may drip from this discharge hose. Therefore must guide the hose without close or block the outlet of the hose.
• Do not insert this hose into sewage hose or cleaning hose 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. 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
) and power supply 2 cord (3
×
4.0
mm
2
) and power supply 3 cord (3
×
1.5 mm
2
), 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 cable and cord harmed by sharp edge, cable and cord must go through bushing (located at the right side of
Mono bloc unit) before carry out electrical connection. The bushing must be used and must not take off.
3. Secure the cable onto the control board with the holder (clamper).
