Location
Allow enough clearance for installing accessories and motor 
servicing when selecting a location (See Fig. 2). If located 
outdoors, use liquid-tight conduit connectors with the junction 
box to provide NEMA 3 weather protection. If mounted 
outdoors in a position other than upright, install a 4074ERU 
Weatherproofing Kit and liquid-tight connectors to provide 
NEMA 3 protection.
Motor Damage Hazard.
Deteriorating vapors and acid fumes can damage 
metal parts.
Install motor in areas free of acid fumes and other 
deteriorating vapors.
In excessive salt environments, mounting base and screws 
should be zinc or cadmium plated, not stainless steel or brass. 
Use the 220738A Adapter Bracket for mounting on these 
surfaces.
