Introduction
1.3 Lubrication
EIM Actuators are factory lled with a high quality lubricant carefully selected to insure
actuator performance under specied operating conditions. Refer to EIM JOB SPEC
SHEET to identify the lubricant provided. Normal operation may not require lubricant
replacement.
1.4 Maintenance
At least once a year a check should be made of your EIM actuator.
a. Disconnect all electrical power to actuator.
b. Open electrical enclosure. Inspect & tighten all electrical connections.
c. Visually inspect for any electrical or mechanical damage.
Replace worn or damaged components.
d. Check lubrication consistency and level. Fill or replace if required.
1.5 Pressure Relief
During operation of electric actuator, the gear temperature increase in combination with
variations of outdoor temperature will cause a small pressure build-up within actuator gear
box. EIM furnishes Pressure Relief Vent Fitting Part No. 83385. Placement on Actuator can
be determined only after eld location and position of valve has been determined. Select
the highest 1/2 NPT vent location on actuator gear box; remove 1/2 NPT plug and replace
with 83385. The possible locations of vent are shown on EIM Outline Drawing.
