2.2 Installation Location
Before selecting the installation site, obtain all required
permissions and follow the below parameters:
·Optimal air distribution is ensured.
·The air path is not blocked or obstructed.
·Condensation is able to drain properly.
·Ensure sufficient clearance for future maintenance and servicing.
·Piping between the indoor and outdoor units should be within the
allowable limits. (Refer to the installation of the outdoor unit
manual)
·The indoor unit, outdoor unit, power supply wiring, and
transmission wiring should be kept at least 3 feet away from
televisions and radio, which prevents image interference and
noise in those electrical appliances.(Noise may be generated
depending on the conditions under which the electric wave is
generated, even if this distance is maintained.)
·Do not install the indoor unit in a machinery shop or kitchen
where vapors from oils or any mists can reach the indoor unit.
Any oils will collect on the heat exchanger, thereby reducing the
performance of the indoor unit, and may deform, and in the
worst case, break the plastic parts of the indoor unit.
·When the unit is installed in a hot and humid place, it is
recommended to insulate the cabinet exterior and to use
auxiliary drain pans.
·If installed above a finished living space, an auxiliary drain
pan(as required by many building codes) must be installed under
the entire unit, and its condensate drain line must be routed to a
location such that the user will see the condensate discharge.
2.3 Installation
NOTE:
These appliances are designed for indoor
installation only.
The indoor units can be installed in one of the
upright, horizontal left, or horizontal right
orientations as shown in the Figures below.
Minor field modifications are necessary to
convert to horizontal left.

2.3b: Horizontal Right Installation (or hanging from ceiling)
2.3c: Horizontal Left Installation (or hanging from ceiling)
The upright installation method is selected by default.
When the unit is horizontal-right mounted, rotate it to
the right by 90 degrees, as shown in the image for
horizontal-right installation (2.3b).
When the unit is horizontally-left mounted (2.3c), the
following steps are required.
1). Disassemble the lower panel and the sealed plate.
2). Disassemble the retaining clips for the evaporator
so that the evaporator can be pulled out along the
lead rail easily.
3). Rotate the evaporator by 180 degrees and insert it
into the upper side of the lead rail.
4). Rotate the unit to the left by 90 degrees, as shown
in the image "2.3b:
5). Reinstall the sealed plate and the lower panel.
2.4 Air Duct
Field duct work must comply with the National Fire
Protection Association NFPA 90NFPA 90B, and any
applicable local ordinances.
WARNING
Do not, under any circumstances, connect return duct
work to any other heat producing device such as a
fireplace insert, stove, etc. Unauthorized use of such
devices may result in fire, carbon monoxide poisoning,
explosion, personal injury or property damage.
