LIMITATIONS

These units must be installed in accordance with all national andlocal safety codes.Ifno localcodesapply,installationmust conform with the appropriate national codes. Units are de signedtomeetNational SafetyCodeStandards.Ifcomponents are tobe added to aunit to meet localcodes, 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. Theymustbe locatedwithinthe building structure,eitherinside 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.

Unitsbeinginstalledvertically orhorizontallycanbe setdirectly 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 nutsare provided in the unit frame to accommodate hanger rods. Knockouts must be removed from the unit panels to expose theseweld nuts. Refer to Figure1 for their location and the individual load on each hanger rod.

WARNING: Be careful when attaching the hanger rods. Use a

washerwith a back-upnut oneachrod andtighten 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 removeany pack

aging until the unit is near the place of installation.

The packaging consists of a bottom wooden skid that can be

liftedwitha forktruckfrom anydirection, a cardboardcontainer thatcovers theentire unit, andstrapping thatsecures thecard 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 itsweight from Table 1. Bef orerigging a unitforhorizontal installation, determineitscenter of gravity from Figure 1, and make sure that its weight will be distributed equally.

CLEARANCES

All unitsrequire certain minimum clearances for proper operation and service. Refer to Figure 12 for these clearances.
