Test Oil Chamber Pressure
1. After installing mechanical seal, attach a vacuum pump to oil
housing.
2. Raise negative pressure inside the oil chamber to 60 cmHg (11.6
in.Hg).
IMPORTANT: DO NOT exceed 60 cmHg (11.6 in.Hg).
3. Hold the vacuum position for 10 seconds. The gauge should
remain absolutely stable.
—Replace mechanical seal upon failing vacuum test.
Test Thermal Protection (CTP)
1. Clean the points of the circle thermal protector (CTP).
2. Check the insulation resistance between each phase connection
on the protector and ground.
—Not less than 30 MΩ with 500V Megger.
