Connect The Cord And Cable To Mono Bloc Unit - Panasonic WH-MDC09C3E8 Service Manual


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.
