Power Supply Removal:
1) Open the starter box door.
2) Remove each plug-in connector, labeled J1 -
J4, from the circuit board. If any of the cables
are not labeled, label them with the appro-
priate plug designator, J1-J4. These must
be plugged into the correct sockets in the
replacement power supply.
3) Remove the four screws holding the power
supply to the starter plate, save them for
mounting the replacement board, and remove
the power supply.
4.14 COOLANT HOSES
The flexible hoses that carry coolant to and from the oil
cooler may become brittle with age and will require
replacement. Have your local Ingersoll-Rand distributor
check them every 2 years.
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.
REMOVAL
Remove enclosure panels.
Drain coolant into a clean container. Cover the container
to prevent contamination. If the coolant is contaminated,
a new charge of coolant must be used.
Hold fitting securely while removing hose.
INSTALLATION
Install the new hoses and reassemble the package by
reversing the disassembly procedure. Start the
compressor and check for leaks.
4.15 FLUID AND VIBRATION MONITORING
Ingersoll-Rand recommends incorporating predictive
maintenance, specifically the use of coolant and vibration
analysis, into all Preventative Maintenance programs.
Predictive Maintenance is designed to increase system
reliability and prevent costly downtime. Through the use
of sophisticated diagnostic tools, including fluid, vibration,
and optional air analysis, IRA Certified Service
Technicians can identify and correct potential problems
BEFORE they can cause expensive unscheduled
downtime.
How does predictive analysis work? By establishing an
initial baseline for normal operation, and then regularly
monitoring fluid and vibration conditions, any sudden
deviation or significant increase from this baseline can be
identified and investigated to pinpoint the cause. More
quickly diagnosing potential problems can directly save
money by preventing costly failures and reducing or
eliminating downtime. In addition, regular condition
monitoring also helps to maximize the time between
expensive preventative maintenance intervals, such as
component rebuilds and coolant changes.
4.16 COOLANT SAMPLING PROCEDURE
Bring unit up to operating temperature. Draw sample,
using pump kit, from separator tank port. DO NOT draw
sample from drain port or oil filter. Use new hose on
pump for each sample, failure to do this can give false
readings.
