4.11 LONG TERM STORAGE
GENERAL
The factory, upon special request, prepares compressor
units for long term storage. In such cases, a special
bulletin is supplied for storage and start-up procedures.
The bulletin provides special procedures for rotation and
lubrication of compressors during storage.
Before actual start-up of the compressor, the unit must
be drained of coolant containing vapor space inhibitors.
Procedure for long term storage start-up is covered in the
special bulletin APDD 339.
4.12 COOLANT/LUBRICANT CHANGEOUT
Ingersoll-Rand does not recommend changeout of
coolant/lubricants, however, if a coolant/lubricant
change cannot be avoided, procedure APDD 106E-87
should be obtained from your Ingersoll-Rand
representative.
4.13 INTELLISYS REMOVAL
Ensure the compressor is isolated from the
compressed air system by closing the isolation
valve and venting pressure from the drip leg.
Ensure the main power disconnect switch is locked
open and tagged (See Figure 4.13-1).

Follow these precautions to minimize damage from
static electricity. Static can cause severe damage to
microcircuits.
1) Make the least possible movement to avoid build-
ing up static electricity from your clothing or tools.
2) Discharge potential static electricity by touching
(grounding) yourself to the starter box.
3) Handle circuit boards only by their edges.
4) Do not place the controller or power supply
assembly on any metal surface.
5) Leave the replacement parts in their protective
bags until ready for installation.
Tools:
Screwdriver Size #1, flathead
3/8 inch hex driver
Before removing any components, open the starter box
door and check all wiring for tightness. A loose wire or
bad connection may be the cause of problems.
This section gives guidelines for removing/replacing the
Intellisys Controller assembly and the Intellisys Power
Supply assembly. The controller is mounted in the
starter box door, and the power supply is mounted on
the upper right corner of the starter backpanel on the
inside-rear of the starter box.
Controller Removal:
1) Open the starter box door.
2) Remove each plug-in connector, labeled P1-P10,
from the sides of the controller. If any of the
cables are not labeled, label them with the
appropriate plug designator, P1-P10.These
must be plugged into the correct sockets in
the replacement controller.
3) Remove and save the Option Module if one is
plugged into P9. This must be installed in the
replacement controller. Note that it is keyed to
plug into P9 only one way.
4) Remove the six holding screws from the con-
troller on the inside of the starter box door.
5) Remove the controller through the front of the
door, being careful to save the gasket that is
between the controller and the door.
