INSTALLATION
OF OUTDOOR UNIT
CHOOSE A LOCATION
Before installing the outdoor unit, you must choose an appropriate
location. The following are standards that will help you choose an
appropriate location for the unit:
•
Meets all spatial requirements shown in figure 6 below.
• Good air circulation and ventilation.
• Firm and solid—the location can support the unit and will not
vibrate.
• Noise from the unit will not disturb others.
• Protected from prolonged periods of direct sunlight or rain.
CHOOSING BASE PAD FOR UNIT
Condenser must be placed securely on a level foundation. The base
can be made out of fiberglass material, stepping stones or pour a
concrete pad. Make sure the unit can bolt into the base material to
secure it properly. Gravel or sand under the base can keep the base
more secure and assist with keeping the unit level.
EXTREME WEATHER CONSIDERATIONS:
If the unit is exposed to heavy wind: Install unit so that air outlet
fan is at a 90° angle to the direction of the wind. If needed, build a
barrier in front of the unit to protect it from extremely heavy winds.
If the unit is frequently exposed to heavy rain or snow: Build a
shelter above the unit it to protect it from the rain or snow. Be
careful not to obstruct air flow around the unit.
IF THE UNIT IS SURROUNDED ON THREE SIDES:
Make sure each side of the unit has 12 in clearance and at least
8 in of clearance from wall. Make sure the fan at the front is not
blocked.
