periods of time, prepare the unit by doing the follow-
ing:
• Depressurize the air tank and open the drain
valve on the tank.
• Cover with a waterproof secured tarp or plastic
sheet to prevent the accumulation of dust, but
leave the bottom open for air circulation. The
covering should allow for easy removal for in-
storage maintenance.
• Whenever possible, store in a sheltered area to
minimize exposure to the elements.
• While in storage, every two (2) to three (3)
months rotate the compressor and motor by
hand to prevent flat spots on the bearings that
will lead to premature failure.
At the end of the storage period, follow the uncrating,
general, and start-up procedures. If the unit has been
stored for more than eighteen (18) months, the IMT
Service Department should be consulted before
restarting the compressor.
NOTE
IMT does not recommend outside
storage.
