LIMITATIONS

These units must be installed in accordance with applicable na tional, local and municipal safety codes.

If components are to be added to a unit to meet local codes, they are to beinstalled atthe dealer'sand/or the customer's ex pense. Refer to Table 1 for Unit Application Data.

LOCATION

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

They may be installed either with ductwork ormatching plenum

and inlet grille. The unit should be located as close to the condensing unit 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

CLEARANCES

The clearances listed on the unit dimension drawing (Figure 9) are required for the proper service and opera tion of the unit.

RIGGING AND HANDLING

Be careful when moving the unit. Do not remove any packaging until the unit is near its final location.

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

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

CAUTION: Spreader bars should be used to prevent slings

from crushing the unit panels and frame.

Before rigging any unit, determine its weight from Ta ble 2. Before rigging a unit for horizontal installation, make sure that its weight will be distributed equally.

VERTICAL/HORIZONTAL INSTALLATION

The unit is shipped for vertical installation with a vertical air discharge as shownin Figure 2, but maybe converted for horizontal installation as shown in Figure 2 by interchanging the solid bottom panel and the return air duct flange.

DUCT CONNECTIONS

All ducts should be designed and installed in accordance with applicable national and/or local codes.

Refer to Figure 3 for suggested method of connecting supply air ductwork.

FIG. 3 - SUPPLY AIR DUCT CONNECTION

Ducts should be sized no smaller than the duct flanges on the unit or the accessory electric heater (if used). Ref er to the unit dimensions (Figure 1) and the heater detail (Figure 4) for these sizes.

Use flexible fiber glass or plastic cloth collars or other non-flammable material at the unit duct connections to minimize the transmission of noise and vibration.

Insulate all ductwork running through unconditioned areas to prevent moisture condensation and to provide more economical operation.

The return air duct flange is factory-mounted on the front of the unit, but it can be reversed with the solid bottom panel for hori zontal applications. When the return air grille is used, the duct connection frame is not used.

NOTE: If return air duct is not used, applicable lnstalltion

The field installed air plenum and return air grille accessories should be used in place of ductwork only when a free blow/free return application is practical.

codes may limit the unit to installation only in a single story residence.
