2 PRODUCT OVERVIEW
Manual override
All INTELLI+ actuators incorporate a handwheel for manual control with an automatic clutch system with
motor-drive priority. The direction of rotation is normally clockwise for closing unless otherwise specified.

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.

2. If stored for more than one year:
• Long-term storage causes the consistency of the grease to change. To avoid any
grease-drying problem, do some rotations of the actuator several times a year by using
motor or manual override.

• 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).
