The FLEX Valve Actuator has 2 seals which require lubrication once a year. These seals are located at the
top and bottom of the actuator, where the shaft exits the actuator housing. Please follow the steps to
lubricate those seals:
Lubricate
1. Turn the actuator power OFF.
2. Remove the knob and the handle.
3. Spread a small amount of silicone base lubricant around the
actuator shaft where it enters the cover (See Fig. 6).
4. Reinstall the handle and knob, do not over-tighten.
5. Push down on the knob and handle to force the actuator
into manual override.
6. Spread a small amount of lubricant around the actuator shaft
where it protrudes from the bottom of the actuator.
7. Turn the handle once around to spread the lubricant.
8. Pull up on the handle and let it click into place.
9. Tighten the knob.

To avoid electric shock which can result in property damage, severe injury or
death, disconnect power to the system at the main circuit breaker before
servicing.
To minimize the risk of injury and avoid damage to the equipment, use a properly
sized, listed Class 2 transformer for connection to the power supply.
