1.Utilization range “A” in accordance with ARI Standard 110. 2.These units can operate in an ambient temperature of

125°F providing the wet bulb temperature of the air enter- ing the evaporator coil does not exceed 67°F. Unit can operate to 0°F if equipped with a low ambient kit.

Installation

Limitations

These units must be installed in accordance with all national and local safety codes. If no local codes apply, installation must conform to the appropriate national codes. Units are designed to meet National Safety Code Standards. If components are to be added to a unit to meet local codes, they are to be installed at the dealer's and/or the customer's expense.

Location

Use the following guidelines to select a suitable location for both the condensing unit and the evaporator.

1.The heat pump is designed for outdoor installation only.

2.The condenser fans are the propeller type and are not suitable for use with ductwork in the condenser air stream.

3.The heat pump and the evaporator should be positioned to minimize the number of bends in the refrigerant piping.

4.The heat pump should be as close to the evaporator as practical.

5.The heat pump should not be installed where normal operating sounds may be objectionable.

6.The evaporator should be located within the building, either outside or inside the conditioned space.

Rooftop Locations

Be careful not to damage the roof. Consult the building contractor or architect if the roof is bonded. Choose a location with adequate structural strength to support the unit.

The heat pump must be mounted on level supports. The supports can be channel iron beams or wooden beams treated to reduce deterioration.

Minimums of two (2) beams are required to support each unit. The beams should: (1) be positioned perpendicular to the roof joists. (2) Extend beyond the dimensions of the section to distribute the load on the roof. (3) Be capable of adequately supporting the concentrated loads at the corners. These beams can usually be set directly on the roof. Flashing is not required.

NOTE: On bonded roofs, check for special installation requirements.

Ground Level Locations

It is important that the units be installed on a substantial base that will not settle, causing strain on the refrigerant lines and possible leaks. A one-piece concrete slab with footers that extend below the frost line is recommended. The slab should not be tied to the building foundation, as noise will telegraph through the slab.
