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.

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.)

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.

Giving consideration to the piping storage, move the unit all the way to the left
side, then cut part of the packaging carton 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

4.1. Connectingpipes(Fig.4-1)
• When commercially available copper pipes are used, wrap liquid and gas pipes
with commercially available insulation materials (heat-resistant to 100 °C or
more, thickness of 12 mm 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 or more).
• Apply thin layer of refrigerant oil to pipe and joint seating surface before
tightening flare nut.
• Use two wrenches to tighten piping connections.
• Use refrigerant piping insulation provided to insulate indoor unit connections.
Insulate carefully.
BFlare nut tightening torque
CDo not apply refrigerating machine oil to the screw portions.
(This will make the flare nuts more apt to loosen.)
DBe certain to use the flare nuts that are attached to the main 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.

5. Drainagepipingwork
5.1. Drainagepipingwork(Fig.5-1)
• 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) available on
the market or hard vinyl chloride pipe (VP-16/O.D. ø22 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.

◆Storinginthepipingspaceoftheindoorunit(Fig.5-3)
* When the drain hose will be routed indoors, be sure to wrap it with commercially
available insulation.
* Gather the drain hose and the refrigerant piping together and wrap them with the
supplied felt tape 3.
* Overlap the felt tape 3at one-half of the tape width.
* Fasten the end portion of the wrapping with vinyl tape, etc.

Connection can be made without removing the front panel.
1. Open the front grille, remove the screw (1 piece), and remove the electrical
parts cover.
* Electrical work can be conducted more effectively with the panel removed. When
attaching the panel, check that the hooks Kat five locations on the air outlet side
are connected securely.
2. Securely connect each wire to the terminal board.
* 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.
4. Fasten each of the wires with the clamp under the electrical parts box.

(2) Seal the service entrance for the remote controller cord with putty to prevent
possible invasion of dew drops, water, cockroaches or worms. (Fig. 6-3)
AFor installation in the switch box:
BFor direct installation on the wall select one of the following:
• Prepare a hole through the wall to pass the remote controller cord (in order to run
the remote controller cord from the back), then seal the hole with putty.
• Run the remote controller cord through the cut-out upper case, then seal the cut-
out notch with putty similarly as above.
