FOR USE WITH THE
The refrigerant R410A requires strict cautions for keeping
the system clean, dry and tight.
Clean and dry
Foreign materials (including mineral oils such as
SUNISO oil or moisture) should be prevented from
getting mixed into the system.
Tight
R410A does not contain any chlorine, does not
destroy the ozone layer, and does not reduce the
earth's protection against harmful ultraviolet radiation.
R410A can contribute slightly to the greenhouse
effect if it is released. Therefore we should take
special attention to check the tightness of the
installation.
Read "6. Refrigerant piping" on page 4 carefully and follow
these procedures correctly.
Since design pressure is 4.0 MPa or 40 bar (for R407C
units: 3.3 MPa or 33 bar), pipes of larger wall thickness
may be required. The wall thickness of piping must be
carefully selected, refer to paragraph "6.2. Selection of
piping material" on page 4 for more details.

NTRODUCTION
This installation manual concerns outdoor units of the Daikin
CMSQ-A7 series. These units are designed for outdoor installation
and used for heat pump applications.
The CMSQ-A7 units can be combined with Daikin indoor units for air
conditioning purposes, and suitable for R410A.
The present installation manual describes the procedures for
unpacking, installing and connecting the CMSQ-A7 units. Installation
of the indoor units is not described in this manual. Always refer to the
installation manual supplied with these units for their installation.
1.1.

Combination

The indoor units can be installed in the following range.
Always use appropriate indoor units compatible with R410A.
