Installation Of The Outdoor Unit; Refrigerant Piping - McQuay SLC Serie Manual De Instalación

Semi-Enclose Mounting
• In case the unit is to be half-recessed into a false ceiling, please check that the unit is well-aligned.
• Provide the installation space as shown in Figure D.
Figure D
The outdoor unit must be installed in such a way, so as to
prevent short circuit of the hot discharged air or obstruction
to the smooth air flow. Please follow the installation
clearance shown in the figure. Select the coolest possible
place where intake air temperature is not greater than the
outside air temperature (maximum 45°C).

Minimum Distance 300
mm (inch) (11.81) (39.37) (11.81) (19.69)
NOTE : If there is any obstacle higher than 2m, or if there
is any obstruction at the upper part of the unit,
please allow more space than the figure indicated
in the above table.
Maximum Pipe Length And Maximum Number Of Bends
If the pipe length is too long, both the capacity and the
reliability of the unit will decrease. As the number of bends
increases, resistance of the piping system to the refrigerant
flow increases and thus lowering the capacity, as a result
the compressor may become defective. See Figure O and
Figure P.
