3.10 INSTALLATION IN ENVIRONMENT WITH
EXPLOSIVE DUSTS
IMPORTANT
Electric actuator ICON 2000 shall be installed
and maintained; according to the applicable rules
regarding the electrical installations in hazardous
area (other than mines) classified as zone 21
(dust); example: EN 50281-1-2 (dust) and/or other
national standards.
4. LUBRICATION
4.1 LUBRICATION INSPECTION
The actuator is lubricated for life, therefore
under normal working conditions it is not
necessary to replace or refill the oil. However it
is recommended to check the oil level every 3-5
years using holes 1 or 2 depending on mounting
position.
The actuator is fitted with oil plugs (parts 1, 2),
so that any assembly on the valve has at least
one oil plug on the upper part of the housing
and one on the lower part.
A spherical head lubricator (part 3) is fitted on
the coupling block for the proper greasing of
the inside thrust or sliding bearings.
The actuator is supplied with oil and greased
where necessary.
