Inspection and Recording
Upon receipt of the actuator, inspect the condition of the equipment and record nameplate
information as follows:
1. Carefully remove actuator from 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. Record the unit nameplate information for future reference; i.e. ordering parts,
obtaining further information.
Storage Procedures
NOTE: The following are our recommended storage procedures to retain maximum product
integrity during short-term storage. Failure to comply with recommended procedures will
void the warranty. For longer-term storage, contact Limitorque for procedures and
recommendations.
Short-Term Storage (less than 1 year)
Units are not weatherproof until properly installed on the valve or prepared for storage.
Store units in a clean, dry, protected warehouse from excessive vibration and rapid temper-
ature changes. If the units 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 pipe plugs and ensure that all covers are tight.
4. If the actuator is mounted on a valve and the stem protrudes from the unit, a suitable stem
cover must be provided.
