INSTALL OUTDOOR UNIT
The outdoor units can be installed on the ground, on the roof, or
mounted on a wall.
NOTE: Install the unit so that the coil does not face into
prevailing winds. If this is not possible and constant wind
winds above 25 mph are expected, use accessory wind baffle.
See installation instructions provided with accessory kit. Wind
baffles should also be used on all units with accessory low
ambient temperature control.
Mounting on Ground
1. Mount unit on a solid level concrete pad.
2. If a heat pump is being installed, use a field- provided snow
stand or ice rack where prolonged subfreezing temperatures
or heavy snow occurs.
3. Position unit so water or ice from roof does not fall directly
onto unit.
4. On cooling only units, an accessory stacking kit can be used
when units are to be stacked. See installation instructions
provided with the accessory kit.
