SECTION 1. OWNER INFORMATION 5 2 5 1 3 4 6 1 3 4 6 2 WINTER HEATING SUMMER COOLING 1. Outdoor air enters the heat pump. 2. The cold, heat-transfer section (outdoor coil) extracts the heat from the air as the refrigerant evaporates from a liquid to a cold gas. 3. The refrigerant, compressed to a hot gas by the heat pump, carries the heat to the heattransfer section (indoor coil). 4. The hot, heat-transfer section (indoor coil) releases the heat as the refrigerant condenses from a gas to a liquid.

2" 36" 36" 36" 6" Figure 4. Minimum Clearances UNIT INSTALLATION Ground Level — When installing the unit at ground level, provide a concrete mounting pad separate from the building foundation. The pad must be level to insure proper condensate disposal and strong enough to support the unit’s weight. Refer to Figure 3. Make sure the slab is a minimum of 2" above the grade and in an area that drains well (See Figure 6). Rigging and Hoisting — The unit should be lifted using slings and spreader bars.

Acoustical Duct Work — Certain installations may require the use of acoustical lining inside the supply duct work. Acoustical insulation must be in accordance with the current revision of the Sheet Metal and Air Conditioning Contractors National Association (SMACNA) application standard for duct liners. Duct lining must be UL classified batts or blankets with a fire hazard classification of FHC-25/50 or less.

interval settings are available: 30 minutes, 60 minutes, and 90 minutes. Time setting selection is dependent on the climate where the unit is being installed. • Example 1. Dry climate of Southern Arizona. A 90 minute setting is recommended. • Example 2. Moist climate of Seattle, Washington. A 30 minute setting is recommended. To set the cycle timer, place the timing pin on the defrost control board to the desired time interval post.
