LIMITATIONS

This unit must be installed in accordance with all national

and local safety codes. If no local codes apply, installation

must conform to the appropriate national code. The unit is

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. See Table 1 for application limitations.

LOCATION

These Evaporator Blowers are not designed for outdoor

installation. They must be located within the building

structure, either inside or outside the conditioned space.

These Evaporator Blower sections allow for vertical or

horizontal installation in any area offering proper electrical

supply, duct and drain connections.

They may be installed either with ductwork or matching

plenum and inlet grille.

The units should be located as close to the condensing 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 metal or wooden beams

can support them.

Units being installed horizontally can be suspended from

above. Four 3/8" weld nuts are provided in the unit frame to

accommodate 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. They

must not be allowed to turn or slip.

CLEARANCES

Refer to the unit dimension details, Figures 12 and 13 for

clearances required for servicing and for proper unit

operation.
