the terminals of the main terminal, main circuit capacitors
or electrical parts and, before touching, be sure that those
voltages are 50

When service panels are removed, live parts can easily be
touched by accident. Never leave the unit unattended
during installation or servicing when the service panel is
removed.

DANGER: DO NOT TOUCH PIPING AND INTERNAL
PARTS

Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.

Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if you
must touch them, be sure to wear protective gloves.

CAUTION

 While following the instructions in this installation

manual, install drain piping to ensure proper drainage
and insulate piping to prevent condensation.
Improper drain piping may result in indoor water
leakage and property damage.

 Install the indoor and outdoor units, power cord and

connecting wires at least 1

meter away from
televisions or radios to prevent picture interference
and noise.
(Depending on the incoming signal strength, a
distance of 1

meter may not be sufficient to eliminate

noise.)

 Remote controller (wireless kit) transmitting distance

can be shorter than expected in rooms with electronic
fluorescent lamps (inverter or rapid start types).
Install the indoor unit as far away from fluorescent
lamps as possible.

 Make sure to provide for adequate measures in order

to prevent small animals from using the outdoor unit
as a shelter.
Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean.

 Install in a machine room that is free of moisture.

The unit is designed for indoor use.

 Do not install the air conditioner in the following

locations:
 Where there is a high concentration of mineral oil

spray or vapour (e.g. a kitchen).
Plastic parts will deteriorate, parts may fall off and
water leakage could result.

 Where corrosive gas, such as sulphurous acid

gas, is produced.
Corroding of copper pipes or soldered parts may
result in refrigerant leakage.

 Near machinery emitting electromagnetic

radiation.
Electromagnetic radiation may disturb the
operation of the control system and result in a
malfunction of the unit.

 Where flammable gas may leak, where there is

carbon fibre or ignitable dust suspensions in the

a. The piping length between all indoor to the nearest branch kit is

≤40

m.

Example: h, i, j … p≤40 m

b. It is necessary to increase the pipe size of the suction gas and

liquid piping if the pipe length between the first and the final
branch kit is over 40

m.
If the increased pipe size is larger than the pipe size of the main
pipe, increase is not allowed, extension till 90

m can not be
done.
Increase the pipe size as follows:

9.5 → 12.7; 12.7 → 15.9; 15.9 → 19.1; 19.1 → 22.2; 22.2 →

Example: unit 8: b+c+d+e+f+g+p≤90 m and b+c+d+e+f+g
>40

m; increase the pipe size of b, c, d, e, f, g.

c. When the piping size is increased (step b), the piping length has

to be counted as double (except for the main pipe and the pipes
that are not increased in pipe size).
The total piping length has to be within limitations (see table
above).
Example:
a+b*2+c*2+d*2+e*2+f*2+g*2+h+i+j+k+l+m+n+p≤300 m.

d. The piping length difference between the nearest indoor from

first branch to the outdoor unit and farthest indoor to the outdoor
unit is ≤40

m.

Example: The farthest indoor unit 8. The nearest indoor unit 1 →
(a+b+c+d+e+f+g+p)–(a+h)≤40

9.7.2 Possible installation patterns and configurations

 The piping between the outdoor units must be routed level or

slightly upward to avoid the risk of oil retention into the piping.

Pattern 1 Pattern 2

1 Piping between outdoor units
2 To indoor unit

Prohibited patterns: change to pattern 1 or 2.

1 Piping between outdoor units
2 To indoor unit
3 Oil remains in piping

 For the gas piping (both discharge and suction gas pipings in

case of the heat recovery system) after the branch, install a trap
of 200

mm or larger using the piping included in the piping kit for
connecting the outdoor unit. Otherwise, the refrigerant may stay
in the piping, causing damage to the outdoor unit.

1 ≥200 mm

 If the piping length between the outdoor unit connecting pipe kit

or between the outdoor units exceeds 2
