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.

4.12COOLANT/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.

4.13INTELLISYS 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.
