3 STORAGE

Introduction
An actuator consists of electrical components plus mechanical parts which have life-long lubrication.
Although the assembly is contained in a waterproof housing, the actuators may suffer from oxidation,
become clogged or seize during commissioning if it has not been stored correctly.
Storage
Actuators must be stored under cover in a clean, dry place which is protected against variations
in temperature.
Avoid storing directly on the ground. If stored in areas subject to damp, apply power to the actuator
to dry it out electrically. Check to ensure that the cable entries are sealed.
Ensure electrical component covers and compartments are properly sealed.
In case of a valve with an important stem lift, check that the stem protection cover is mounted
on the actuator. If not, assemble it with a weak sealing paste.
Inspection following storage
1. If stored for less than one year:
• Visual inspection of electrical parts.
• Operate buttons, selectors, etc. manually to ensure that they can be used without
difficulty.
• Perform a few movements manually.
• Check consistency of grease.
• Commission the actuator.
2. If stored for more than one year:
• Long-term storage causes the consistency of the grease to change. Thinly applied
grease on shafts or spindles dries out. The mechanical part of the actuator therefore
needs to be stripped and then reassembled using fresh grease.
• Visual inspection of electrical parts.
• Operate buttons, selectors, etc. manually to ensure that they can be used without
difficulty.
• For the actuators equipped with battery option. During the storage period, the circuit
is in low comsumption mode which allows to get a long lifetime of the battery. Beyond
a storage time of 3 years it is better to replace the batteries at the commissioning.
You can check the battery status at any time on the display.

4 ACTUATOR ON VALVE ASSEMBLY

Actuator should be secured directly to the valve using proper bolts or via a proper interface.
After assembly, the actuator can operate in any position. However, cable glands should not be
oriented upwards (loss of water tightness) and the motor will preferably not be positioned at the
bottom (potential internal condensation trap)
Note 1: do not lift the actuator by handwheel, it could damage the wormwheel gear.
Note 2: see § 31 for details on storage precaution prior to starting-up.
Note 3: Greasing of A form drive bush has to be done prior to mounting actuator on valve (in the
case of a rising stem valve).
