2. Wind insulating tape around the pipes and drain hose
avoiding to compress the insulation too much.
3. Finish wrapping insulating tape around the rest of the
pipes leading to the outdoor unit.
4. The pipes and electrical cables connecting the indoor
unit with the outdoor unit must be fixed to the wall with
suitable ducts.
Must fit tightly against
body without any gap.

All refrigerant connection must be accessible, in order
to permit either unit maintenance or removing it
completely.
5. Select the insulation of the refrigerant pipe.
 Insulate the gas side and liquid side pipe referring to the
thickness according to the pipe size.
 Indoor temperature of 30°C and humidity of 85% is the stan-
dard condition.
If install in a high humidity condition,use one grade thicker
insulator by referring to the table below.
If installing in an unfavorable conditions,use thicker one.
 Insulator’s heat-resistance temperature should be more than
120°C.
 Install the insulation not to get wider and use
the adhesives on the connection part of it to
prevent moisture from entering.
 Wind the refrigerant pipe with insulation tape
if it is exposed to outside sunlight.
 Install the refrigerant pipe respecting that the
insulation does not get thinner on the bent part
or hanger of pipe.
 Add the additional insulation if the insulation
plate gets thinner.

1.
Install the drain hose as short as possible.
 In order to discharge condensation water, the
drain hose should keep tilted.
 Fix the drain hose with Cable-Tie, so that it will
not separate from the machine.
 The drain pump connection port is used when
using a drain pump.
Note
2.
When there is no drain pump, Insulate and fix the drain
hose according to the figure.
 Lock steel ring of the drain hose according to the
figure.
 Wind and wrap steel ring and drain hose fully
with thermal insulation sponge; fix both ends of
external layer with ribbon for thermal insulation.

Install the drain hose as short as possible.
note
 In order to discharge condensation water, the
drain hose should keep tilted.
 Secure the drain hose with the cable-tie not to be
separated from the unit.
 The drain pump connection port is used when using
a drain pump.

When there is no draining pump, insulate the drain hose
and then fix it as a picture.
note
 Insert the drain hose to bottom of the outfall of water
basin.
 Lock steel ring of the drain hose according to the figure.
 Wind and wrap steel ring and drain hose fully with
thermal insulation sponge; fix both ends of external
layer with ribbon for thermal insulation.
 After being installed, drain hose must be insulated fully
by heat insulating material.(To be provided at site.)
