Installation Procedures
9.Install outlet flange
Install outlet flange basising the needs, the outlet flange is standard component, bolts are laied in accessories box.
Note:
You can select not to connect with the flange. Instead of it, you can use the round plastic air outlet (purchased by user)
10. Examples for Bad Installation
The unit is not equipped with the air return pipe and the inner side of the suspending ceiling is used as the blast pipe,
causing the humidity increasing due to irregular air mass, strong wind or sunlight from the outside world.
There might be condensate dropping down at the outer side of the blast pipe. The humidity is high, even if the inner side
of the suspended ceiling isn't used as a blast pipe in new concrete buildings. At this time, the whole body should use the
thermo wool for heat preservation (the thermo wool can be packed with a steel wire).
It is operated under the conditions beyond the limits, leading to the overload of the compressor.
Affected by the capacity of the exhaust fan, and the strong wind and wind direction in the outer flue, when the blowing
quantity of the air conditioner exceeds the limits, the drained water of the heat exchanger will overflow, causing water
leakage.
11. Static Pressure GradeSetting
For MVAH036~048MV2AA units, after installation need to preliminary estimates external static pressure, according to the
external static pressuresetting the unit's static pressure grade by controller.
Note: The detail operation methods for setting the unit's static pressure grade refer to the controller manual.
The static pressure range of each gradeas follows:
