INSTALLATION

Pre-InstallationInspect the contents of this accessory package before installing. File a claim with the shipper if there is shipping damage or if a part is missing.

Step 1 — Install Field-Fabricated Wind Baffles

WARNING

To avoid the possibility of electrical shock, open all discon- nects before installing or servicing this accessory.

On size 040-060 units, in areas with prevailing winds of more than 5 mph (8 kph) and where temperatures drop below 32 F (0° C), wind baffles must be field fabricated to ensure

proper cooling cycle operation at low-ambient temperatures with Motormaster V controls. Wind baffles are not needed on size 030, 035, and 070-100 units. See Fig. 2 for baffle details. Use 20-gage (1 mm) galvanized sheet metal, or similar corro- sion-resistant material for the baffles. Use field-supplied screws to attach baffles to unit. Screws should be 1/4-in. (6.3 mm) diam- eter or larger. Screws should not be more than 1/2-inch in length. Drill required screw holes for mounting baffles.

CAUTION

To avoid damage to refrigerant coils, electrical compo- nents, and wiring use extreme care when drilling screw holes and screwing in fasteners.
