Installation Procedure
Selecting the mounting position to install the indoor units
■
Select suitable places where the outlet air can be sent to the entire room, and convenient to
lay out the connection pipe, connection wire and the drainage pipe to outdoor.
■
The ceiling structure must be strong enough to support the unit weight.
■
The connecting pipe, drain pipe and connection wire shall be able to go though the building
wall to connect between the indoor and outdoor units.
■
The connecting pipe between the indoor and outdoor units as well as the drain pipe shall be
as short as possible.
■ If it is necessary to adjust the filling amount of the refrigerant, please refer to the installation manual attached with
the outdoor unit.
■ The connecting flange should be provided by the user himself.
■
The indoor unit has two water outlets one of which is obstructed at the factory (with a rubber cap). Only the outlet
not obstructed (liquid inlet and outlet side) will be generally used during installation. If applicable, both the outlets
should be used together.
■
An access port must be provided during installation of indoor unit for maintenance.
After selecting the unit installation location, proceed the following steps:
1. Drill a hole in the wall and insert the connecting pipe and wire through a PVC wall-through tube
purchased locally. The wall hole shall be with a outward down slope of at least 1/100.
2. Before drilling check that there is no pipe or reinforcing bar just behind the drilling position. Drilling
shall avoid at positions with electric wire or pipe.
3. Mount the unit on a strong and horizontal building roof. If the base is not firm, it will cause noise, vibration or
leakage.
4. Support the unit firmly.
5. Change the form of the connection pipe, connection wire and drain pipe so that they can go through the wall hole
easily.
