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.

Installation impossible

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

To persons in charge of piping work:

Be sure to open the shut-off valve after piping
installing 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
the freon collection and destruction law.

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.
