In case drain work on your outdoor unit is neccessary, follow the guidelines below.
•Two drain outlets are provided in the bottom plate of unit (drain plug and drain hose are field supply).
• In cold areas, do not use a drain hose with the unit. Otherwise,drain water may freeze and block the drain. In case
the use of a drain hose is unavoidable for one reason or another, it is recommended to install a heater tape in order
to protect drain from freezing.

provide a free space of more than 100 mm under the outdoor unit.
