3.3. Whenembeddingpipesintothewall(Fig.3-5)
• The pipes are on the bottom left.
• When the cooling pipe, drain pipes internal/external connection lines etc are to
be embedded into the wall in advance, the extruding pipes etc, may have to be
bent and have their length modified to suit the unit.
• Use marking on the mount board as a reference when adjusting the length of the
embedded cooling pipe.
• During construction, give the length of the extruding pipes etc some leeway.

B Reference marking for flare connection
C Through hole
D On-site piping
3.4. Preparingtheindoorunit
* Check beforehand because the preparatory work will differ depending on the
exiting direction of the piping.
* When bending the piping, bend gradually while maintaining the base of the
piping exiting portion. (Abrupt bending will cause misshaping of the piping.)
* Cut off outlet of the pipe depending on the exiting direction of the piping.

2. Wrap the felt tape 3in the range of the refrigerant piping and drain hose which
will be housed within the piping space of the indoor unit.
• Wrap the felt tape 3securely from the base for each of the refrigerant piping
and the drain hose.
• Overlap the felt tape 3at one-half of the tape width.
• Fasten the end portion of the wrapping with vinyl tape.

3. While inserting the refrigerant piping and drain hose into the wall penetration
hole (penetration sleeve), hang the top of the indoor unit to the mount board 1.
4. Move the indoor unit to the left and right, and verify that the indoor unit is hung
securely.
5. Fasten by pushing the bottom part of the indoor unit onto the mount board 1.
(Fig. 3-10)
* Check that the knobs on the bottom of the indoor unit are securely hooked into
the mount board 1.
6. After installation, be sure to check that the indoor unit is installed level.

Cut part of the shipping box and wrap into a cylindrical form as illustrated in the
diagram. Hook this to the rear surface rib as a spacer, and raise the indoor unit.
4. Connect the refrigerant piping with the site-side refrigerant piping.
5. Fasten by pushing the bottom part of the indoor unit onto the mount board 1.
* Check that the knobs on the bottom of the indoor unit are securely hooked into
the mount board 1.

• When commercially available copper pipes are used, wrap liquid and gas pipes
with commercially available insulation materials (heat-resistant to 100 °C, 212 °F
or more, thickness of 12 mm, 1/2 inch or more).
• The indoor parts of the drain pipe should be wrapped with polyethylene foam
insulation materials (specific gravity of 0.03, thickness of 9 mm, 23/64 inch or more).
• Flare the ends of the refrigerant pipes. A
• Apply refrigerating machine oil over the entire flare seat surface. B
• Use the flare nuts as follows. C
•
For connection, first align the center, then tighten the first 3 to 4 turns of flare nut by hand.
• Use 2 wrenches to tighten piping connections. D
• Use refrigerant piping insulation provided to insulate indoor unit connections.
Insulate carefully.
• After connecting the refrigerant piping to the indoor unit, be sure to test the pipe
connections for gas leakage with nitrogen gas. (Check that there is no refrigerant
leakage from the refrigerant piping to the indoor unit.)
• Use flared nut installed to this indoor unit.
• In case of reconnecting the refrigerant pipes after detaching, make the flared part
of pipe re-fabricated.

1. Remove the flare nut and cap of the indoor unit.
2. Make a flare for the liquid pipe and gas pipe and apply refrigerating machine oil
(available from your local supplier) to the flare sheet surface.
3. Quickly connect the on site cooling pipes to the unit.
4. Wrap the pipe cover that is attached to the gas pipe and make sure that the
connection join is not visible.
5. Wrap the pipe cover of the unit’s liquid pipe and make sure that it covers the
insulation material of the on site liquid pipe.
6. The portion where the insulation material is joined is sealed by taping.

• Drain pipes should have an inclination of 1/100 or more.
• For extension of the drain pipe, use a soft hose (inner dia. 15 mm, 19/32
inch) available on the market or hard vinyl chloride pipe (VP-16/O.D. ø22 mm,
55/64 inch PVC TUBE). Make sure that there is no water leakage from the
connections.
• Do not put the drain piping directly in a drainage ditch where sulphuric gas may
be generated.
• When piping has been completed, check that water flows from the end of the
drain pipe.
Caution:
ThedrainpipeshouldbeinstalledaccordingtothisInstallationManualto
ensure correct drainage. Thermal insulation of the drain pipes is necessary

Connection can be made without removing the front panel.
1. Open the front grille, remove the screw (2 pieces), and remove the electrical box
cover.
* Electrical work can be conducted more effectively with the panel removed.
When attaching the panel, check that the hooks Kat three locations on the air
outlet side are connected securely.
2. Securely connect each wire to the terminal block.
* In consideration of servicing, provide extra length for each of the wires.
* Take care when using strand wires, because beards may cause the wiring to
short out.
3. Install the parts that were removed back to their original condition.
