Product Overview

Figure-18 Current and Obsolete Valve Linkages.

Figure-19 Current and Obsolete Damper Linkages.

MAINTENANCE

The actuator is sealed in oil and requires no maintenance.

Regular maintenance of the total system is recommended to assure sustained, optimum

performance.

TROUBLESHOOTING

Use the following steps to locate malfunctions:

1. Check the actuator by applying the proper supply voltage.

2. The motor should run when power is applied. If it does not run, the actuator is

inoperative and should be replaced.

3. While the motor is running, the actuator should extend. If it does not extend, check the

mechanical linkage for any damage or misadjustment which could prevent the actuator

from extending. If the mechanical linkage is inoperative, adjust the linkage or replace

the damaged components, as applicable. If the mechanical linkage moves correctly and

freely, the problem lies in the actuator and it must be replaced.

4. If applying power directly to the actuator results in correct operation of the actuator, the

actuator and linkage are functional, and the problem lies in the wiring or thermostat.

Repair or replace the wiring or thermostat, as applicable.

FIELD REPAIR

None. Replace an inoperative actuator with a functional unit.
