8. SELECTING INSTALLATION LOCATION OF INDOOR UNIT
8.1 CONSIDERATIONS OF SELECTING INSTALLATION LOCATION
Select installation location which allows
minimum clearances for free air circulation
and easy accessibility for service and
maintenance.
Select outlet location of piping from indoor
unit which allows easy access to the ends
of refrigerant piping lines to facilitate
refrigerant leak testing and to facilitate
service and maintenance.
Select installation location so that the wall
hole required to pass the outlet refrigerant
piping lines, electrical cables and
condensate drain line from indoor unit can
be in one of the following Four outlet
locations as indicated by (1), (2), (3), (4)
and (5)
Avoid installation location which can lead to
excessive length of refrigerant piping lines
between indoor and outdoor units
Avoid installation location which can lead to
excessive height difference between indoor
and outdoor units
