1.
The air inlet SHALL be located at least 12" from a wall or
other obstruction for unrestricted air flow.
2.
The air outlet SHALL be located so as to direct discharged
air away from the building. (Avoid low overhanging roofs to
avoid recirculation of condenser discharge air on vertical
discharge models.)
3.
Mount the unit on a sturdy base approximately 4" to 6"
above the ground. A concrete slab is recommended. If
concrete blocks are used, be sure to use well-tamped
gravel-fill beneath the blocks to prevent settling. If timbers
are used, use at least 6" x 6" timbers plus gravel-fill to
prevent settling.
4.
A concrete slab should not be in contact with the building
foundation to prevent possible sound or vibration
transmission.
5.
Locate the outdoor unit as close as possible to the indoor
unit. A shorter line set run will reduce refrigerant pressure
drop for increased system performance and reduce system
refrigerant charge for greater reliability.
6.
If practical, unit should be located on the south side of the
structure away from northerly winds to minimize the effects
of blowing snowdrifts and freezing rain. A wind screen or
wind block can also be used. In areas known for snow
accumulation, the unit should be elevated at least 18" above
the ground.
7.
Placement of the unit should be in a well-drained area, or the
unit MUST be supported high enough so run-off will not
enter the unit.
8.
Avoid installations under roof overhangs without guttering.
Water draining from the roof onto the unit could produce
excessive noise and may cause ice to build up on the coil or
fan during cold weather.
9.
Do not locate where heat, lint or exhaust fumes will be
discharged on the unit (as from dryer vent). Rooftop
installation is acceptable in areas of low snow
accumulations, provided the roof will support the unit and
provisions are made for water drainage and the noise or
vibration through the structure.
1.
Refer to the instructions supplied with the evaporator coil.
2.
When installing the evaporator, refer to page 8 for
condenser evaporator match-up. The evaporator should be
installed in an insulated plenum of proper size to
accommodate the coil, whether it be of the “A” coil or “H” coil
type design. Be sure no air can bypass the coil as this can
seriously hamper unit operation.
3.
Install condensate drain as shown below. Use drain
connection size or larger.
4.
Emergency drain facilities SHALL be installed on any
application where water damage may occur due to overflow,
leaking or sweating of condensate drain pan.
DO NOT OPERATE WITHOUT TRAP. UNIT MUST BE LEVEL OR SLIGHTLY INCLINED TOWARD DRAIN.
