2.3 Inspection and Recording
Upon receipt of the actuator:
1. Carefully remove the actuator from the shipping carton or skid. Thoroughly examine the equipment for any physical damage that
may have occurred during shipment. If damaged, immediately report the damage to the transport company.
2. A nameplate is attached to each actuator. Record this information for future reference, i.e. ordering parts or obtaining further
information.
2.4 Storage Procedure
NOTE: The following is our recommended storage procedure to retain maximum product integrity during storage. Failure to comply
with recommended procedures will void the warranty. For longer-term storage, contact Limitorque for procedures and
recommendations.
Storage (less than 1 year)
Actuators are not weatherproof until properly installed on the valve or prepared for storage.
Store actuators in a clean, dry, protected warehouse, away from excessive vibration and rapid temperature changes. If the actuators
must be stored outside, they must be stored off the ground, high enough to prevent them from being immersed in water or buried by
snow.
1. Position the actuator in storage with motor and switch compartment horizontal.
2. Connect the internal heaters (if supplied) or place desiccant in the switch compartment.
3. Replace all plastic caps or plugs with metal pipe plugs and ensure that all cover bolts are tight.
4. If the actuator is mounted on a valve and the stem protrudes from the actuator, a suitable stem cover must be provided.
