Installation
The wall you select should be strong and solid
enough to prevent vibration
1. Mount the installation plate on the wall with 
type "A" screws. If mounting the unit on a concrete
wall, use anchor bolts.
• Mount the installation plate horizontally by aligning
the centerline using a level.
2. Measure the wall and mark the centerline. It is also
important to use caution concerning the location of
the installation plate-routing of the wiring to power
outlets is through the walls typically. Drilling the
hole through the wall for piping connections must
be done safely.

Installation
Flaring Work
Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the following procedure.
Cutting the pipes and the cable.
1. Use the piping kit accessory or the pipes purchased
locally.
2. Measure the distance between the indoor and the
outdoor unit.
3. Cut the pipes a little longer than measured distance.
4. Cut the cable 1.5m longer than the pipe length.
Removing burrs
1. Completely remove all burrs from the cut cross sec-
tion of pipe/tube.
2. Put the end of the copper tube/pipe in a downward
direction as you remove burrs in order to avoid drop-
ping burrs into the tubing.
Putting nut on
• Remove flare nuts attached to indoor and outdoor unit,
then put them on pipe/tube having completed burr
removal.
(not possible to put them on after flaring work)
Flaring work
1. Firmly hold copper pipe in a die in the dimension
shown in the table below.

Check
1. Compare the flared work with the figure by.
2. If a flared section is defective, cut it off and do flaring
work again.
Indoor
Preparing the indoor unit's piping and drain hose for installation through the wall.
CAUTION: If the drain hose is routed inside the room, insulate the hose with an
insulation material* so that dripping from "sweating"(condensation) will not dam-
age furniture or floors.
*Foamed polyethylene or equivalent is recommended.
1. Route the indoor tubing and the drain hose in the
direction of rear left or right
2. Tape the tubing, drain hose and the connecting cable.
Be sure that the drain hose is located at the lowest
side of the bundle. Locating at the upper side can
cause drain pan to overflow inside the unit.
