(FAN OL/LOW WATER display)
Air Demand is Too Great
Dirty Air Filter
Pressure Regulator Out of Adjustment
Defective Pressure Regulator
Broken Sullicon Spring
Leak in Control System Causing Loss of
Pressure Signals
Defective Solenoid Valve
Defective Blowdown Valve
Ruptured Sullicon Control Diaphragm
Plugged Control Line Filter
Clogged Return Line Strainer or Orifice
Separator Element Damaged or Not
Functioning Properly
Leak in the Lubrication System
Excess Fluid Foaming
Fluid Level Too High
Defective Pressure Relief Valve
Water Vapor Condensation From Cooling
and Compression Occurs Naturally
MAINTENANCE
REMEDY
Check fluid level.
Check for clogged fluid filter.
Check the cooling fan motor or water flow sys-
tem.
Check service lines for leaks or open valves.
Check for filter maintenance message on supervi-

Replace.
Clean or repair if necessary.
Clean strainer (screen with o-ring replacement kit
available)
Clean orifice.
Check Separator Differential (plugged) dP1.
Change Separator
Check all pipes, connections and components.
Drain and change.
Drain excess fluid.
Replace pressure relief valve.
Remove the water vapor from compressed air
prior to distribution through the air system. Check
operation of aftercooler and moisture separator.
Install a compressed air dryer sized for the flow
and dryness level required. (Note: Filters may also
be required to remove particulates, liquid oil
aerosols or for oil vapor removal. Change car-
tridges as recommended by the filter manufactur-
er.) Check all drain traps routinely to insure their
proper operation. Maintain them regularly.
