The numerical figures used in here represent the dimensions for the
71-100-125 class models. Figures between (  ) indicate the
dimensions for the 100-125 class models. (Unit: mm)

(Refer to 

"Precautions on installation" on page 3

)

Precaution

(A) In case of non-stacked installation 

(See figure 1)

(B) In case of stacked installation

1.

In case obstacles exist in front of the outlet side.

2.

In case obstacles exist in front of the air inlet.

Do not stack more than one unit.

About 100 mm is required as the dimension for laying the upper
outdoor unit's drain pipe. Get the portion A sealed so that air from the
outlet does not bypass.

(C) In case of multiple-row installation (for roof top use, etc.)

1.

In case of installing one unit per row.

2.

In case of installing multiple units (2 units or more) in lateral
connection per row.

Relation of dimensions of H, A and L are shown in the table below.

Selection of piping material

Construction material: phosphoric acid deoxidized seamless
copper for refrigerant.

Temper grade: use piping with temper grade in function of the
pipe diameter as listed in table below.

The pipe thickness of the refrigerant piping should comply with
relevant local and national regulations. The minimal pipe
thickness for R410A piping must be in accordance with the table
below.

O=Annealed
1/2H=Half hard

Obstacle is present

Discharge side obstacle

1

In these cases, close the 
bottom of the installation 
frame to prevent the 
discharged air from 
being bypassed

Left side obstacle

Right side obstacle

In these cases, only 2 
units can be installed.

Installation impossible

All field piping must be installed by a licensed refrigeration
technician and must comply with relevant local and
national regulations.

NOTE

To persons in charge of piping work:

Be sure to open the shut-off valve after installing
piping and vacuming is complete. (Running the
system with the valve closed may break the
compressor.)

It is forbidden to discharge refrigerant into the
atmosphere. Collect the refrigerant in accordance
with relevant local and national regulations.

Do not use flux when brazing the refrigerant piping.
For brazing, use phosphor copper brazing filler metal
(BCuP) which does not require a flux.
(If a chlorine flux is used, the piping will corrode, and if
the flux contains fluoride, it will cause the coolant oil to
deteriorate, adversely affecting the coolant piping
system.)
