INSTALLATION

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.

WARNING

Electrical Power Hazard. Line voltage can cause death or serious injury and short equipment circuitry.

Disconnect power supply before installation.

CAUTION

Electrical Shock or Equipment Damage Hazard. Low voltage can shock individuals or short equipment circuitry.

Disconnect power supply before installation.

Determine Appropriate Mounting Orientation

See Fig. 2 for mounting orientation.

NOTES:

— Actuators are shipped in the fully closed position. — An arrow molded into the hub points to tick marks

on the label to indicate the hub rotary position.

— See Fig. 3 for proper mounting to a square damper

shaft.

IMPORTANT

All wiring must agree with applicable codes, ordinances and regulations.

Location

The actuators are designed to open a damper by driving the damper shaft in either a clockwise or counterclockwise

direction. The actuator housing has two slots on the

bottom, either of which, with a 205649 Mounting Bracket, secures it flush to a damper box (see Fig. 2).

NOTE: When mounted correctly, these slots allow the

actuator to float without rotating relative to the damper shaft.

CAUTION

Equipment Damage Hazard. Tightly securing actuator to damper housing can damage actuator.

Mount actuator to allow it to float along its vertical axis.

Preparation

Before mounting the actuator onto the damper shaft, determine the: — Damper/valve opening direction for correct spring return

rotation. The actuator can be mounted to provide clockwise or counterclockwise spring return.

— Damper shaft size (see Specifications section).

Fig. 3. Proper mounting to square damper shaft.

DAMPER SHAFT

Measure Damper/Valve Shaft Length

If the shaft is less than three inches in length, the shaft coupling must be located between the damper/valve and actuator housing. If the shaft length is more than three inches, the shaft coupling may be located on either side of the actuator housing.

If the coupling must be moved from one side of the actuator to the reverse, follow these instructions (see Fig. 4):

1. Remove the retainer clip from the shaft coupling and set

it aside for later use.

2. Remove shaft coupling from one side of the actuator.

3. Replace the shaft coupling on the opposite side of the

actuator aligning it based on the stroke labelling.

4. Replace the retainer clip on the shaft coupling using the

groove of the coupling.
