12.6 CONDENSED WATER DISPOSAL OF
OUTDOOR UNIT
• There are holes on the base of Outdoor unit for
condensed water to discharge
• In order to drain out the condensed water, the unit
is installed on a stand or a block so that the unit is
100mm above the ground as the shown figure.
Join the drain pipe to one hole.
• At first insert one portion of the hook to the base
(Portion A), then pull the drain pipe in the direction
shown by the arrow while inserting the hook into
the base. After installation, check whether the
drain pipe cling to the base firmly.
When Use and Install in Cold Areas
• When using in cold region with severe cold
climate and heavy snow, water discharged from
the heat exchanger will freeze on the base
surface and this may block the drainage. In such
regions, remove the bush on the bottom face of
outdoor unit to prevent water build up leading to
icing and blockage. Keep a minimum gap of
250mm between the base and the ground. When
using drain pipe, consult your sales agent
