MAINTENANCE
The FLEX Dryer requires little maintenance for satisfactory opera-
tion. Good dryer performance can be expected if the following
routine maintenance steps are taken.
General
For continued good performance of your refrigerated dryer,
all refrigeration system maintenance should be performed by
a competent refrigeration mechanic.
NOTE:
Before corrective maintenance is done during the war-
ranty period, call your local distributor and proceed according to
instructions. Refer to the warranty for limits of your coverage.
Daily Maintenance
Check the operation of the no loss drain valve at least once
daily. See the Field Service Guide for remedies to drain valve
malfunctions.
Monthly Maintenance
It is recommended to inspect the condenser coils monthly.
If necessary, remove dirt or other particles with compressed
air from an OSHA-approved air nozzle that limits its discharge
pressure to 30 psig (2.1 kgf/cm
2
).
Yearly Maintenance
It is recommended to replace the drain service unit annually.
For units purchased with a filtration package, replace prefilter
and afterfilter elements annually.
Maintenance kits are available to facilitate annual maintenance.
Vent Drain Valve
The vent drain valve is located in the air inlet pipe to allow for
the draining of liquid that may build there under low flow
conditions. In the event the outlet pressure dew point exceeds
normal values during low load conditions, open the valve for no
more than 5 seconds to remove the liquid and reclose the valve.
NOTE:
Condensate may contain oil. Comply with applicable laws
concerning proper disposal.
Disconnect power supply and depressurize dryer before
servicing. Dismantling or working on any component of
the compressed air system under pressure may cause
equipment failure and serious personal injury.
