LONG TERM STORAGE
GENERAL
Upon special request, the factory prepares compressor units for
long term storage. The following modifications are incorporated
into the compressor for protection during storage:
1. Motor space heaters in motor to protect against condensation
in high humidity areas.
2. Compressor system charged with vapor space inhibitor to prevent
oxidation throughout the system.
3. Oxidation inhibitors placed within the electrical enclosures
to prevent condensation in electrical components.
4. Filters, silencers and mufflers wrapped and sealed for protection
from harmful ambient conditions.
CAUTION
VAPOR SPACE lNHlBlTOFlS
AND OXIDATION INHIMTORS
Before actual start-up of the compressor, the unit must be
drained of all lubricant containing vapor space inhibitors and
all oxidation inhibitors removed from electrfcal enclosures.
REFER TO THE OPERATION SECTION of this manual for storage
instructions, initial preparation and start-up instructions. However,
before placing the unit into operation, the vapor space inhibitors and
oxidation inhibitors must be removed and new Ultracoolant must be
added.

DURING STORAGE
1. An Ingersoll-Rand Long Term Storage package arrives on site ready
to be placed in storage. The following procedures must be followed
to prepare the compressor for proper storage:
A) Rotate the drive motor several rotations by hand in the proper
direction of rotation (See rotation arrow on motor). This can
be accomplished by carefully turning the motor rotor with the
fan blades located at either end of the rotor. This will prevent
the bearings in the motor and compressor from developing flat
spots which can cause pre-mature failure after start-up.
B) Check filters, silencers and mufflers which are exposed to
atmosphere to ensure they are wrapped with plastic and sealed
with tape.
C) Connect motor space heaters to 115VAC power source. This is
required when the unit is stored in a high humidity location.
(Refer toPublication APDD 333-9OA)
D) Record details of initial storage setup on log sheet (Page 5).
2. Thereafter each month perform the following checks and record
on the inspection sheet:
A) Rotate the motor as described in Step 1, Item A until the time
the unit is placed in service.
B) Recheck filters, silencers and mufflers to ensure they are
sealed.
C) Check oxidation inhibitors in electrical enclosures to ensure
they are not more than (18) months beyond the installation date.
Oxidation inhibitors that are beyond this expiration date should
be replaced with Ingersoll-Rand part number 39132634.
3. If the storage time should exceed a total of six months from the
date the unit was shipped from the factory, regrease the motor using
the amount and type of grease described in the maintenance section
of the Operators Manual of the specific unit stored. The motor should
be regreased at six~month intervals until the unit is placed in service.
Dates of regreasing should be recorded on the inspection sheet.
After regreasing, continue to rotate the motor each month as
previously described.

PREPARATION FOR START-UP
1. ALL lubricant with vapor space inhibitor must be removed from the
system to ensure proper lubricant life. The oxidation packets must
be removed from the electrical enclosures and, sealing material
must be removed from the filters, silencers and mufflers.
WARNING
No drainage points should be opened
until the compressor has been isolated
electrically and all air pressure has been
removed from the system.

2. To drain the compressor, use the drain valve and hose which are
located at the bottom of the separator tank. A hand operated
transfer pump connected to the drain hose is a convenient
method to remove the used lubricant from the separator sump
into a container.
3. The lubricant will drain more completely and any particles
suspended in the lubricant will be carried out more completely
if the lubricant is hot during drainage.
WARNING
Extreme care should be exercised when
draining the hot lubricant so that no possibility
of injury to personnel exists.
To accomplish having hot lubricant in the system, the compressor
should be started and operated at load conditions until it comes
up to temperature (approx. five (5) min.). The compressor should
then be shutdown and old lubricant removed. At the end of the
drainage process the lubricant filter element must be replaced.
4. Remove the lubricant filter and replace with a new element.
See specific unit operators manual for instructions.
5. After the unit is drained and lubricant filter element replaced,
close the drain valve and refill the system with Ingersoll-Rand
Ultrawolant. See specific unit operators manual for instructions.
6. Care must be taken to ensure the lubricant filter, lubricant cooler,
airend bearings and associated piping are as full as possible. Fill
separator tank until lubricant is half to three fourths full in the
sight glass.
Start the compressor and run for a short time. Unload compressor
and check lubricant level in the sight glass. Lubricant should
be at the mid point of the sight glass when operated in the unloaded
mode. This procedure should be performed several times to ensure
there are no air pockets in the system when the compressor is
operated.
7. After the preceding procedures have been completed, the unit
can be put into service. However, the initial lubricant changeout
schedule as listed in the operators manual must be changed. After
150 hours of operation, both the lubricant and the lubricant filter
element must be changed. The standard maintenance schedule
should be followed thereafter.
