9. MAINTENANCE AND STORAGE INSTRUCTIONS

Maintenance
If actuators is correctly mounted and sealed, no special maintenance is required. Check once a year function
of motor and make sure that switch compartment is condensation free. If environment is humid, we
recommend installation of an anti-condensation heater resistance and/or breathers, thus protecting electric
parts from alteration.
Actuators are lubricated with grease for about 100.000 operations. If the grease requires to be renewed, use
one of the products listed hereafter.
NOTE : When renewing the grease, first remove the integrality of the old one.
General characteristics of lubricant ; grease specifications only (not actuator) given for standard duty
conditions :
• Grease duty temperature : -30°C to +135°C,
• Penetration ASTM at +25°C : 265/295,
• Drop point : +180°C.

Storage
The actuators includes electric equipment as well as grease lubricated gear stages. In spite of the
weatherproof enclosure, oxydising, jamming and other alterations are possible if actuator is not correctly
stored.
Actuators stored in a stock room
a) The actuators should be stored under a shelter, in a clean and dry place and protected from wide
temperature variations. Avoid placing the actuators directly on the floor.
b) For actuators equipped with an heating resistance, it is recommended to connect and power supply it
especially if the storage area is humid (standard 230 VAC, unless other specification).
c) Check that the temporary sealing plugs of the cable entries are well in place. Make sure that the covers
and the boxes are well closed to ensure weatherproof sealing.
d) In the case of a valve with rising stem having a long stroke, verify that the protection tube is well mounted
on the actuator. If not, fix it with sealing paste.
Actuators installed but waiting for electrical connection
If a long period of time is expected between the actuator mounting and the electrical wiring works :
a) Visually check the tightness of electrical box cover and cable glands.
b) Cover the device with a plastic protective film.
c) For actuators equipped with an heating resistance, it is recommended to connect and power supply it
especially if the storage area is humid (standard 230 VAC, unless other specification).
Storage of actuators equipped with electronic components:
Long term storage of electronic components which are not in service increases the malfunction risk. This
practice is therefore highly unadvisable.
If a long term storage is absolutely necessary, we strongly recommend a revision of the electronic boards in
our factory before actuator usage.
Control after storage :
a) Visually check the electric equipment,
b) Operate manually the microswitches, buttons, selectors, etc., to insure the correct mechanical function,
c) Operate apparatus manually,
d) Verify the correct grease consistency,
e) For actuators equipped with grease nipple, remember to complete with some fresh grease.
