INSTALLATION

rate request for inspection by the carrier's agent should be made in writing.

LIMITATIONS

These units must be installed in accordance with all national and local safety codes. If no local codes apply, installation must conform with the appropriate national codes. Units are de- signed to meet National Safety Code Standards. If components are to be added to a unit to meet local codes, they are to be in- stalled at the dealer's and/or the customer's expense. See Ta- ble 2 for application limitations.

LOCATION

These indoor units are not designed for outdoor installation. They must be located within the building structure, either inside or outside the conditioned space.

The units should be located as close to the outdoor units as practical and positioned to minimize bends in the refrigerant piping.

Units being installed vertically or horizontally can be set directly on a floor or platform, or they can be supported by metal or wooden beams.

Units being installed horizontally can be suspended from above. Four 3/8" weld nuts are provided in the unit frame to ac- commodate hanger rods. Knockouts must be removed from the unit panels to expose these weld nuts. Refer to Figure 1 for their location and the individual load on each hanger rod.

WARNING: Be careful when attaching the hanger rods. Use a washer with a back-up nut on each rod and tighten down against the cabinet so they will not be al- lowed to turn or slip.

RIGGING AND HANDLING

Exercise care when moving the unit. Do not remove any pack- aging until the unit is near the place of installation.

The packaging consists of a bottom wooden skid that can be lifted with a fork truck from any direction, a cardboard container that covers the entire unit, and strapping that secures the card- board container to the bottom skid.

These units can be rigged with slings under the bottom skid.

CAUTION: Spreader bars should be used to prevent the slings from crushing the unit panels and frame.

Before rigging any unit, determine its weight from Table 1. Bef- ore rigging a unit for horizontal installation, determine its center of gravity from Figure 1, and make sure that its weight will be distributed equally.

CLEARANCES

All units require certain minimum clearances for proper opera- tion and service. Refer to Figure 12 for these clearances.
