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
standard 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.
Insulation’s heat-resistance temperature should be more
than 120°C.

When installing insulation in places and conditions
below, use the same insulation that is used for high
humidity conditions.
<Geological condition>
- High humidity places such as shoreline, hot spring, near
lake or river, and ridge (when the part of the building is
covered by earth and sand.)
<Operation purpose condition>
- Restaurant ceiling, sauna, swimming pool etc.
<Building construction condition>
- The ceiling frequently exposed to moisture and cooling is
not covered.
e.g. The pipe installed at a corridor of a dormitory and
studio or near an exit that opens and closes frequently.
- The place where the pipe is installed is highly humid due
to the lack of ventilation system.

You can contact the gas side and liquid side pipes but
the pipes should not be pressed.
When contacting the gas side and gas side pipe, use 1
grade thicker insulation.

• 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.

Drain pipe and Drain hose Installation
1.
Install a drain pipe according
to following instruction.
2.
When you complete the drain
hose installation, pour water
to make sure water is drained
properly.
• Make sure to keep the drain hose from getting
tangled or loosed (on the connection part).
• If it is necessary, connect a extension hose (drain hose)
to drain hose for indoor unit and insulate the external
surface of the extension hose if it is connected in indoor.
• If you installed a drain pipe underneath the
refrigerant pipe, make sure to fix the drain hose firmly.
• If you install the drain hose by drilling a hole on a
wall, make sure that slope is downward.
3.
When passing the drain hose through the hole drilled in the
wall, make sure to avoid following cases.

• Since the draining is of natural drain type, install the
drain hose in downward direction.
• If you do not tie the drain hose with a cable tie,
leakage may occur.
• Drain pipe may get clogged if there is any foreign
substances within the drain pan, so you must remove
any foreign substances after completing the
installation.
• Do not use the drain hose (extension hoses) that is
connected by number of hoses together.
- Water may leak from the connection part, therefore
install the drain hose in one piece. However, if the
length is too short and you cannot avoid connecting
number of drain hoses together, make sure to use
silicone sealant or other material for water-proofing
measures. (Do not use insulating tape.)
