OUTDOOR UNIT (SEE FIGURE 3 FOR
INSTALLATION DIMENSIONS)
1. Some localities are adopting sound ordinances based on the unit's
sound level registered from the adjacent property, not from the
property where the unit is installed. Install the unit as far as possible
from the property line.
2. When possible, do not install the unit directly outside a window.
Glass has a very high level of sound transmission. For proper
placement of unit in relation to a window see Figure 3.
3. Install unit level or, if on a slope, maintain slope tolerance of 2
degrees (or 2 inches per 5 feet) away from building structure.
4. Install the unit high enough above the ground or roof to allow ade-
quate drainage of defrost water and prevent ice or snow build-up
(required for heat pumps).
5. In heavy snow areas, do not locate the unit where drifting will occur.
The unit base should be elevated above the depth of average
snows.
6. When installed in areas where low ambient temperatures exist,
locate unit so winter prevailing winds do not blow directly onto out-
door unit.
7. If unit coil cannot be installed away from prevailing winter winds, a
wind barrier should be constructed. Size barrier at least the same
height and width as outdoor unit. Install barrier 12 inches minimum
from the sides of the unit in the direction of prevailing winds as illus-
trated in Figure 2.
8. Locate unit away from overhanging roof lines which would allow
water or ice to drop on, or in front of, coil or into unit.
9. Install in a location that has good airflow.
10. Install in a location that has a rigid wall or support to minimize the
sound operation and/or vibration.
11. Slab or roof mounting - install the unit a minimum of 4 inches above
the roof or ground surface to avoid ice build-up around the unit.
Locate the unit above a load bearing wall or area of the roof that
can adequately support the unit. Consult local codes for rooftop
applications.
12. Install in a location that's far away from combustible materials and
vapors.
13. Install in a location that's at least 10 ft away from a TV and radio
antennas to avoid possible interferences with the operation of the
air conditioner/heat pump.
14. Install the unit horizontally.
Avoid the following places for installation where air conditioner trouble
is liable to occur.
• Where flammable gas could leak.
• Where there is an excessive amount of machine oil in the air.
• Where sulfide gas is generated such as a hot spring.
• Where there is high-frequency equipment.
CONDENSATE DRAINAGE REQUIREMENT (HEAT
PUMP ONLY)
Condensate formed during the heating and defrost processes must be
drained from heat pump units. Drain holes are provided in the base of
the units to ensure proper drainage. Heat pumps must be raised when
installed on a concrete pad or the ground to allow drainage to occur. If
the heat pump unit is installed on a wall mounting bracket, insert the
provided drain connector into one of the 1 inch drain holes and attached
a field-provided insulated drain hose to the connector. Use the provided
rubber plugs to cover any unused drain holes. See Figure 4.
In rooms where inverter type fluorescent lamps are used, the signal
from the wireless remote controller may not be received.

FIGURE 3: Clearances for Outdoor Unit
It is advisable to make a piping loop near outdoor unit so as to
reduce vibration.
For increased efficiency, install the outdoor unit in a location where
continuous direct sunlight or excessive water can be avoided as
much as possible.
When operating the air conditioner in low outside temperature, be
sure to follow the instructions described below.
• Never install the outdoor unit in a place where its air inlet/outlet
side may be exposed directly to wind.
• To prevent exposure to wind, install the outdoor unit with its air inlet
side facing the wall and a baffle board on the air outlet side.
