1. Before Installation
2. Choosing an Installation Site
1.1 Determine the route to move the unit to the installation site.
2.2 First unseal and unpack the unit. Then hold the four lifting lugs to
move the unit. Refrain from exerting force on other parts of the
unit, especially the refrigerant piping, water discharge piping, and
plastic parts.
1. In creating the air return plenum on the air inlet panel, make sure the air
grilles are angled such that they are parallel to the direction of the air inlet.
See Figure 2.4.
2. There should be no angle between the air inlet grille and the direction of
the air inlet, otherwise the noise level will increase. For example, the
method used to create the air inlet grille in Figure 2.5 is wrong.
3. When the air outlet panel is connected to the air outlet flange of the unit body
via the metallic air diffuser, make sure that the sheet metal contact surface is
properly sealed and insulated using sponge, as shown in Figure 2.6.
2.1 Choose a site that fully complies with the following conditions and
user requirements to install the air conditioning unit.
Well ventilated.
Unobstructed airflow.
Strong enough to bear the weight of the indoor unit.
Ceiling has no obvious slant.
There is sufficient space for repair and maintenance work to be
carried out.
No leakage of flammable gas.
The length of the piping between the indoor and outdoor units is
within
the permitted range (refer to the manual on installation of
the outdoor unit).
The static pressure of the air duct of the indoor unit is within the
permitted range (see 6.2 Fan performance).
2.2 Install with M10 or W3/8 lifting bolts.
2.3 The space required for installation (unit: mm) is shown in
Figure 2.1:
2.4 The air return plenum is adjusted based on the on-site
installation space:
There are two kinds of air return modes for this series of models.
One is back return air which is the factory default. The other is
bottom air return which can be customized or adjusted on-site.
Refer to the following diagrams on the adjustment method.
