installation of the minimum air duct and pipe connection. The height of ceiling should consider the
condensate water discharging height and service room. According the distance of unit’s four
fastening brackets and the height of ceiling joist, make sure the location and height of four sleeves.
The helix length on the sleeve can adjust the level degree of indoor unit and make sure of the
unobstructed condensate water discharge.
2.3 Installation of Ducting Air Line
The ducting air line should be accordance with the local regulation. Make sure that the air line is
insulated on its entire length. Unit should be equipped with muffler by 300-500mm length soft pipe
to reduce the noise. When installing the air line, lay the air outlet line and air return line according
with the static pressure, or it can lead to insufficient air quantity or noise.
2.4 Installation of Outdoor Unit
In order to get maximum cooling performance, the outdoor unit should be installed according to
the following items:
A) The unit installation location should face away from the prevailing wind and avoid air
discharging in that direction.
B ) No obstacle in the location between the air discharging and intake.
C) Install an awning to protect the outdoor unit.
D) Verify that any wall on which the outdoor unit is installed is capable of carrying the unit’s
weight. Do not install on a light unstable structure or vibration.
E) Do not install the unit in a highly polluted area in which the air is contaminated by oil mist,
salt or sulfuric gas.
2.5 Safety Notice
Make sure the outdoor unit location allows easy access for servicing, air inflow and outflow.
Provide minimum disturbance to the owner and nearby neighbors.
Minimum distance between the indoor unit installation location and outdoor unit location, and
minimum quantity of refrigerant pipe bends.
2.6 Tube Connection
The standard tube length is 8/15m. The unit interconnecting tube length can influence the cooling
or heating capacity of unit. Tubing route shall be kept to straight lines as much as possible. When
installing, keep the number of tube bends to a minimum. If bends are necessary, perform them only
by using professional tube benders and not manually; make sure an ideal height difference between
the indoor unit and outdoor unit.
