(B) 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 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 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)

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 refinery plant), such substances may lead to failure of the

unit.
