Installation and Maintenance
NOTE:
These appliances are designed for indoor
installation only.
The indoor units can be installed in one of the
up
right
, horizontal left
,
or horizontal right
orientations as shown in
the
Figures below.
Minor field modifications are necessary to
convert to horizontal
left
.

I
nstallation
Before
selecting
the installation site, obtain
all required
permissions and follow the below parameters:
·
Optim
al
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 i
f
this
distance is maintained.)
·
Do not install the indoor unit in a machinery shop or
kitchen
where vapor
s
from oil
s
or
any
mist
s
can reach
the
indoor unit.
Any
oil
s
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.

The u
p
right
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 clip
s
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

.
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 ordinance
s
.
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.
