2.3.2 Installation Site
Select an installation site where the following conditions are fulfilled and that meets your customer's
approval.
(1) Obstructions should be moved away from the intake or outlet vent of the indoor unit so that the airflow can
be blown throughout the room.
(2) Make sure that the installation meets the requirement of the schematic diagram of installation
spaces.
(3) Select the place where it can withstand four times the weight of the indoor unit and would not
increase operating noise and vibration.
(4) Ensure horizontal position of the installation place.
(5) Select the place where it is easy to drain condensate water, and connect with the outdoor unit.
(6) Make sure that there is enough space for care and maintenance, and the height between the
indoor unit and ground is above 1800mm (6ft).
(7) When installing the suspension bolt, check if the installation place can withstand four times the
weight of the unit. If not, reinforce it before installation.
Note: There could be a large amount of greasy dirt accumulated on the fan, heat exchanger and water
pump located in a dining room and kitchen, which would reduce the capacity of the heater exchanger,
and lead to leakage and abnormal operation of the water pump.
