=.se instructions explain the recommended method of

,llation of the PWC heat pump unit and associated

e_uctricalwiring.

This unit is designed and approved for use as a self- contained air to air heat pump system.

These instructions, and any instructions packaged with mating components and/or accessories, should be carefully read prior to beginning installation. Note particularly any CAUTIONS or WARNINGS in these instructions and all la- bels on the units.

These instructions are intended as a general guide only, for use by qualified personnel and do not supersede any national or local codes in any way. Compliance with all local, state, provincial or national codes pertaining to this

Check the unit rating p'lateto confirm specifications are as ordered.

Location

The design is certified for through-the-wall installation only. The interior portions of the unit may be surrounded by a closet with clearances to combustible material held to 0" at sides, 0" top and 0" front of the plenum.

The grille side of the unit may be flush with, or extend beyond, the face of the exterior wall, but should not be recessed more than 2" from the face of the building and should not be obstructed with trees, landscape materials or building structure.

There is no minimum clearance required on locating the unit to an interior corner of a building. If the unit is to be enclosed, provisions should be made allowing access to the indoor side of the unit for changing filters and for inspection. At least 33" of unobstructed space should be provided in front of the indoor side, whether enclosed or not, to permit removal of the cooling chassis should repairs or inspection be required.
