In the case of flaring for R410A with the
*
conventional flare tool, pull out it approx.
0.5 mm more than that for R22 to adjust
to the specified flare size. The copper
pipe gauge is useful for adjusting projec-
tion margin size.

Installation

NOTE : For installation, at least 3 dimensions should be
kept free from obstacles (walls).
As shown in the figure, hang power cord
and connecting cable downward, and
take out it along piping connection port.

1. Piping connections to the outdoor unit should be
arranged in the sequence A, B, C, D starting from the
bottom. (For each piping connection, the gas pipe is
on the bottom and the liquid pipe is on the top.)

2. When multiple indoor units are to be connected to
9.0
the outdoor unit, make the ends of the pipes and
wires from each indoor unit to ensure that they will
13.0
be connected to the outdoor unit correctly.

(Problems caused by indoor units being connected
to the outdoor unit incorrectly are very common in
A multiple-unit installations.)
3. The length and height difference of the connecting
pipes between the indoor and outdoor units must be
within the ranges indicated below.
• Total piping length :
4 units (A + B + C + D) Multi,
Non. Additional refrigerant .................. 70 m
3 units (A + B + C) Multi,
Non. Additional refrigerant .................. 50 m
• Minimum piping length :
A or B or C or D = 2 m or more
• Maximum indoor piping length :
A or B or C or D = 25 m or less
• Maximum piping height difference :
A or B or C or D = 15 m or less
• Maximum piping/height
difference between 2 units
= 15 m or less
4. Connect 2 or more indoor units for heat pump.
5. If the outdoor unit is to be mounted on a wall, make
sure that the platform supporting it is sufficiently
strong. The platform should be designed and
manufactured to maintain its strength over a long
period of time, and sufficient consideration should be
given to ensuring that the outdoor unit will not fall.
6. When the outdoor unit is to be mounted high on a
wall, take particular care to ensure that parts do not
fall installer is protected.
7. When doing installation work on level ground, it is usual
to wiring and piping connections to the indoor units.
And/then make to the outdoor unit.
However if outdoor work is difficult it is possible instead
to make changes to the procedure.
For example by making adjustments to the wiring and
piping length on the inside (rather than the outside).
