Standard Maintenance

Approx. every 2 years:
Under normal operating conditions, the XTE3000 requires no formal maintenance; however,
visual inspection for oil leakage or external visible damage is recommended every two years.
When conditions are severe (frequent operation or high temperatures), inspect the oil level
and oil quality more frequently. Replace all seals that permit oil leakage or water ingress.
WARNING
Installation, configuration, commissioning, maintenance, and repairs must be performed
by approved and qualified personnel only.
WARNING
Before performing service or maintenance operations (unless otherwise indicated), ensure
that power is turned off to the unit to avoid injury and/or damage to equipment.
WARNING
The actuator is non-intrusive. The control compartment is sealed in dry and clean conditions
and contains no site serviceable components. Do not open it unless absolutely necessary.
Unauthorized access will invalidate the warranty.
CAUTION
Using a fastener other than the approved type may result in damage to the actuator or valve.
The following checks will assure optimum performance and can be considered as good
practice in preventive and/or predictive maintenance:

External visual inspection and general health check
Electrical enclosures: Check the external parts for possible damage and replace
them immediately if necessary. If the window glass is broken, the complete cover
must be replaced (see Section 13, Parts list and drawings for individual item
numbers).
Electrical enclosures: perform an internal check of the cable glands and tightness
of cable terminals, and replace the cover O-ring.
Make sure that there are no oil leaks from the actuator housing. Check the oil
level; it should be approximately 20 mm from the fill plug. Top-up the oil volume if
needed (see Section 4, Lubrication).
Lubricate the internal components of the coupling block (if present) via the
spherical head lubricator using suggested greases (see Section 4, Lubrication).
If the stem is external, check that the valve stem is clean and lubricated. If not,
clean and lubricate it in order to prevent damage to the threaded bush.
