REQUIRED MAINTENANCE
INSPECTION
Frequency
Verify operation of the solenoid and auto float drain system.
Weekly or
as required.
Verify refrigeration analyzer gauge is in the correct range.
Verify operation of both cooling fans.
Disconnect and lockout dryer power as well as compressed air supply and
depressurize prior to performing the following maintenance items.
General Maintenance
Frequency
Clean refrigeration condenser coil by blowing dust and dirt from the inside of the cabinet
out. (Opposite from normal fan air flow) Be sure to clean condenser fan motor to provide
adequate cooling and fan blades to allow proper balance.
Monthly
Isolate the valve prior to the Solenoid drain system and remove and clean the strainer
screen
Monthly
Replace filter element of inline filters.
6 Months or
High differential
Drain Service
Frequency
If the drain system is not discharging condensate and the strainer is clean, try cleaning
debris from diaphragm, or replacing the solenoid or timer.
As Required
If the drain system is continually discharging condensate and air from the drain tube, try
replacing the solenoid valve diaphragm, or the complete drain valve.

To obtain flow capacities at conditions other that standard (SCFM @ 100 PSIG, 100°F Inlet & 100°F
Ambient), locate the multiplier at the interception of actual operating conditions. Multiply the rated capacity
of the selected dryer by the selected multiplier. The result is the corrected flow capacity. Flow rates in
excess of specified due to capacity correction can result in increasing pressure drop.
