When Installing this Product...

1. Read these instructions carefully. Failure to follow them

could damage the product or cause a hazardous

condition.

2. Check the ratings given in the instructions and on the

product to make sure the product is suitable for your

application.

3. Installer must be a trained, experienced service

technician.

4. After installation is complete, check out product

operation as provided in these instructions.

CAUTION

Electrical Shock or Equipment Damage Hazard.

Can shock individuals or short equipment

circuitry.

Disconnect all power supplies before installation.

Motors with auxiliary switches can have more than one

disconnect.

CAUTION

Equipment Damage Hazard.

Can damage the motor beyond repair.

Never turn the motor shaft by hand or with a wrench.

Forcibly turning the motor shaft damages the gear train

and stroke limit contacts.

IMPORTANT

Always conduct a thorough checkout when

installation is complete.

Location

Allow enough clearance for accessory installation and motor

servicing when selecting a location (see Fig. 1). 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.

CAUTION

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.

Mounting

Use the following guidelines for proper motor mounting:

• Always install motors with the crankshaft horizontal.

• Mounting flanges extending from motor housing base are

drilled for 1/4 inch (6.4 mm) machine screws or bolts.

• Non-Spring Return Motors are shipped from the factory in

the closed position (at the limit of counterclockwise rotation,

as viewed from the power end of the motor).

• Spring Return Motors are shipped from the factory in their

normal position.

• Normally closed models are shipped at the limit of

counterclockwise rotation, as viewed from the power end of

the motor.

NOTE: Refer to Fig. 2 for graphical representation of

fully-open and fully-closed positions.
