INSTALLATION
Pre-Installation —
Inspect 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
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.
