PI Operation Manual
5. Upon receipt, considering that the oil-lubricated drivers are not shipped oil-filled, fill the reservoir
to maximum level with properly selected oil with rust and corrosion inhibitors.
Always drain the oil before moving the pump, to avoid any damages, and refill the
motor on its new location.
6. Rotate the shaft of the motor once a month.
7. Some form of heating must be used to prevent condensation. This heating should maintain the
winding temperature at a minimum of 9 °F (5 °C) above the surrounding ambient temperature.
There are three options:
• If space heaters are supplied, they should be energized.
• If none are available, single phase or "trickle" heating may be utilized by energizing one phase
of the motor's windings with a low voltage, producing heat in the winding conductor.
Request the required voltage and transformer capacity from the driver manufacturer.
• A third option is to use an auxiliary heat source and keep the windings warm by either convection
or blowing warm dry air into the motor.
Be careful not to overheat, since keeping the temperature of the motor frame 9 °F
(5 °C) above the surrounding ambient temperature is sufficient.
After the storing period, follow the next steps as start-up preparations:
1. Motor should be thoroughly inspected and cleaned to restore to an "As Shipped" condition.
2. Motors, which have been subjected to vibration, must be disassembled and each bearing
inspected for damage.
3. Oil and/or grease must be completely changed using lubricants and methods recommended on
the motor's lubrication plate, in the "LUBRICATION" section of the driver manufacturer's manual.
4. If storage has exceeded one year, the motor manufacturer's Quality Assurance Department
must be contacted prior to equipment start-up for any special recommendations.
