10.0 MAINTENANCE
No Loss Drain Trap (where fitted) Check / Cleaning
Remove the four socket head screws then carefully
split the trap. Clean and inspect all internal parts
with particular attention to the water level sensor(s).
If the stainless steel strainer mesh is blocked, remove
it and clean in a weak detergent solution.
Replace any defective parts (see parts manual for
repair kit).
Re−assemble and later, with machine running, check
that condensate is expelled at regular period and no
alarms are signaled on trap or on INTELLISYS display.
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, IR 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.

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 a new hose on
pump for each sample, failure to do this can give false
readings.
