(Refer to "Precautions on installation" on page 4)

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 not allowed

Piping and other pressure containing parts shall
comply with the applicable national and international
regulations and shall be suitable for refrigerant. Use
phosphoric acid deoxidised seamless copper for
refrigerant.

Installation shall be done by a licensed refrigerant
technician, the choice of materials and installation
shall comply with national and international
regulations. In Europe the EN378 is the application
standard that shall be used.

To persons in charge of piping work:

Be sure to open the stop 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.
