NOTICE

In rooms where inverter type fluorescent lamps are used, the signal from the wireless remote controller may not be received.

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.

NOTICE

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.

NOTICE

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.

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.
