S
Disconnect any electrical cables to the valve (or
trap).
S
Determine the type of condensate drain device
and continue in the appropriate section below:–
Aluminium Trap (where fitted) Check / Cleaning
S
Remove the four socket head screws and nuts
then carefully split the trap. Clean and inspect all
internal parts.
S
Check the action of the float and the condition of
seals.
S
Replace any defective parts (see parts manual for
repair kit).
S
Re–assemble and later, with machine running,
check that condensate is expelled at regular
periods.
Timed Solenoid Drain Valves (where fitted) Check
/ Cleaning
S
Remove the central nut and then the electrical
coil.
S
Remove screws holding bonnet of valve and
carefully split the valve. Clean and inspect all
internal parts.
S
Similarly check and clean the ball valve and
needle valve.
S
Replace any defective parts as identified in parts
manual.
S
Re–assemble and later, with machine running,
check that condensate and air is expelled at
frequency and duration set into the INTELLISYS
controller (see section 9.6).
No Loss Drain Trap (where fitted) Check /
Cleaning
S
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).
S
If the stainless steel strainer mesh is blocked,
remove it and clean in a weak detergent solution.
S
Replace any defective parts (see parts manual for
repair kit).
S
Re–assemble and later, with machine running,
check that condensate is expelled at regular
period and no alarms are signalled 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.
