1. Before Installation
1. Determine the route to move the unit to the installation site.
2. First unseal and unpack the unit. Then hold the four seats of the
hanger to move the unit. Refrain from exerting force on other parts
of the unit, especially the refrigerant piping, water discharge
piping, and plastic parts.
3. The Fresh Air Processing Unit can be used either independently
or in conjunction with other types of indoor unit. If used
independently, the total capacity of the Fresh Air Processing Units
must be between 50% and 100% of that of the outdoor units. If
used in conjunction with other types of indoor unit, the total
capacity of the indoor units and Fresh Air Processing Units must
be between 50% and 100% of that of the outdoor units and the
total capacity of the Fresh Air Processing Units must not exceed
30% of that of the outdoor units.
2. Choosing an Installation Site
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).
Caution
• If the indoor ambient temperature and relative humidity
exceed 30°C and 80%, attach insulation materials at a
thickness greater than 10 mm to the unit body.
2.2 Install with M10 or W3/8 lifting bolts.
