N
In a heavy snowfall area, do not install the drain plug and drain cap
into the outdoor unit. It may cause frozen ground, therefore take ap-
propriate measures to prevent it.
General area
While the heat pump is running in heating mode, ice can begin to accumulate on the surface of condenser. To prevent ice from growing,
the system goes into defrost mode and the ice on the surface turns to water. Dripping water from condenser must be eliminated
through running drain holes, to prevent ice growing at low temperature.
▪
In case there isn't enough space for drainage out of the unit, additional drain work are required. Follow the description as below.
▪
Make space more than 100 mm between the bottom of the outdoor unit and the ground for installation of the drain hose.
▪
Connect the drain hose to the drain plug.
▪
Make sure the drain hose stays free from dust and small branches

1. Prepare a water drainage channel around the foundation, to drain waste water away from around the unit.
2. Make sure the installation of the outdoor unit is made in such a way so that the drainage functions satisfactorily. This could entail
that you have to build up the unit from its foundation, so you can lead waste water away from the vicinity.
3. When installing the unit in a place frequently exposed to snow, pay special attention to elevate the foundation as high as possible.
