is shipping damage or if a part is missing.
INSTALLATION
Step 1 — Install Field-Fabricated Wind Baffles
In areas with prevailing winds of more than 5 mph and
where temperatures drop below 32 F, wind baffles must be field
fabricated to ensure proper cooling cycle operation at
low-ambient temperatures with Motormaster V controls, not
needed on size 060 units with MCHX (Microchannel heat ex-
changers). See Fig. 2 for baffle details. Use 20-gage (1 mm) gal-
vanized sheet metal, or similar corrosion-resistant material for
the baffles. Use field-supplied screws to attach baffles to unit.
Screws should be
1
/
4
-in. (6.3 mm) diameter or larger. Screws
should not be more than
1
/
2
inch in length. Drill required screw
holes for mounting baffles.
