NOTICE
Wide variations in the temperature of the actuator body for electrical valve assemblies will
cause moisture to accumulate within the actuator. This accumulated moisture will damage
the electrical components and void the actuator warranty. Once power is applied to the
actuator, an internal heater will protect the actuator from moisture accumulations.
While the actuator is in storage in an un-powered condition, the actuator must be protected
in a climate-controlled room. Installed actuators must remain powered for the internal
heater to prevent damage from condensation. In regions with low relative humidity where
condensation is unlikely to form, the actuator should be protected from sunlight and stored
in a well ventilated, dry environment or covered with a loose fitting waterproof canvas or
tarp with bottom open, to prevent heat buildup.
Failure to follow these instructions may void warranty.
Do not wrap with plastic.
Valves with assembled electric actuators, including valves with long stem extensions, should be
stored in a climate-controlled building. Normal temperature and humidity variations outdoors or in
unheated buildings may result in condensation, which could accumulate inside un-powered
actuators. If a climate-controlled building is not available, then the actuators should be powered
during storage. Each actuator has an internal compartment heater to prevent condensate
accumulation.
All hand-operated valves should be in the open position unless otherwise indicated herein, and
metallic valves should be coated with an exterior film of oil. All valves regardless of storage
location must be opened and closed at least two times, twice a month during the storage period. This
will help prevent seizing and possible damage to inside seats.
Long Term Storage
Valves with assembled electric actuators, including valves with long stem extensions, should remain
powered.
If actuated valves are removed from the piping system for storage the internal compartment heaters
must be re-connected to the power source during the entire storage period.
If conditions allow, all valves should be cycled two times monthly. All valves removed from the
system must be stored in the vertical position making sure they cannot roll or fall over.
All spare actuators should be stored vertically inside, in a climate-controlled building. All conduit
openings or plastic protection caps or plugs need to be replaced with threaded pipe plugs to ensure
all openings are sealed.
