Every 6 months, more frequently if levels increase
Replace shaft seal
When leak rate exceeds 7-8 drops per minute
(a) Check bolts, shim packs, centre inserts, keys and all bolt torque.
(b) Check and torque all terminals in the processor and starter panel per the specification posted in the enclosure.
(c) Check calibration of slide valve, slide stop and pressure.
(d) Booster: 20,000 h. High-stage/air conditioning: 10,000 h. One stage: 30,000 h.
(e) Not for flange motors.
(f) Vibration measurement must be carried out continuously to obtain optimum preventive control on bearings. If not continuously controlled then every
6 months, more frequently if levels increase. Alternatively, major overhaul after maximum 30000 h.
(g) Verify tightness of bolts on suction and discharge flanges on a daily basis. See Table 48 for torque requirements.
Leak test: According to national rules or as a minimum according to EN 378-2 (Minimum annually if leak rate < 1% year)
Safety equipment: Check of safety equipment (Safety switch devices, pressure relief valve) according to national rules. Minimum requirement according
to EN 378, annual check of safety switch devices and every 5 years for pressure relief valve.
