Application Information MWM-J-2009
As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to achieve
maximum cooling capacity, the location selected for outdoor unit should fulfi ll the following requirements:
Install the condensing (outdoor) unit in a way such that hot air distributed by the outdoor condensing unit
cannot be drawn in again (as in the case of short circuit of hot discharge air). Allow suffi cient space for
maintenance around the unit.
Ensure that there is no obstruction of air fl ow into or out of the unit. Remove obstacles which block air
intake or discharge.
The location must be well ventilated, so that the unit can draw in and distribute plenty of air thus lowering
the condensing temperature.
A place capable of bearing the weight of the outdoor unit and isolating noise and vibration.
A place protected from direct sunlight. Otherwise use an awning for protection, if necessary.
The location must not be susceptible to dust or oil mist.
Installation Clearance
Outdoor units must be installed such that there is no short circuit of the hot discharge air or obstruction to
smooth air fl ow. Select the coolest possible place where intake air should not be hotter than the outside
temperature (max. 45˚C).
ALL MODELS A B C D
Minimum Distance 300 mm 1000 mm 300 mm 500 mm
CAUTION : If the condensing unit is operated in an atmosphere containing oils (including machine oils), salt (coastal area),
sulphide gas (near hot spring, oil refi nery plant), such substances may lead to failure of the unit.
