WARNING
Different duct connections may result in slightly different system
efficiency
For heat pump air outlet connected with duct, when heat pump is
operating, condensated dew will be generated outside the air
outlet duct. Please pay attention to the discharge of conden-
sated water.
The diameter of the
duct must ≥190mm, total length of the ducts should not be
longer than 10m and the maximum static pressure should not
exceed 50kPa. Bear in mind that the number of bends
should not exceed five.
There is a filter on the inlet. In terms of the heat pump connected
with duct, additional filter may be put forward to the air inlet of
duct to protect possible blockage.
(Fig.4-5-4 and Fig.4- 5-5)
To drain condensated water from evaporator, please install the
heat pump on a level platform. The maximum allowed inclination
angle of the unit to the ground should be no more than 2° to the drain
vent side.

Heat pump is not recommend to be installed outdoors where
there is no rain cover or weathershed.
Warning: In case of rain entering the internal components of the
heat pump, components might be damaged hence causing
physical danger. (Fig.4-5-1)

In cases where the heat pump is installed outdoors, a reliable
water-resistant measure must be used to avoid water
ingress into the heat pump.
