(2) Installation of Outdoor Unit
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
fulfill the following requirements:
• Install the condensing (outdoor) unit in away 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 sufficient space for maintenance around the unit.
• Ensure that there is no obstruction of air flow 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 flow. Select the coolest possible place where intake air should not
be hotter than the outside temperature (max. 45°C)
