a.Filter/Regulator/Gauge (F/R/G) Assembly

The compressed air supply to the dryer is connected into the 3/8-inch F.P.T. fitting of the F/R/G assembly which is located at the bottom rear of the right side of the base.

The F/R/G assembly performs three (3) essential functions. The filter removes most solids and liquid particles from the compressed air stream and traps them in its bowl where this waste can be readily removed through the drain valve at the bottom of the bowl.

The filter bowl should be cleaned monthly.

The regulator will maintain a nearly constant outlet air pressure so that the dryer’s air pistons will function normally despite upstream air pressure variations. After the compressed air is connected into the F/R/G assembly, adjust the regulator knob so that the gauge needle reads 80 PSI (5.51 bars).

b.Optional Automatic (Piston Operated) Load/Unload Doors

If the dryer is equipped with the automatic door option then the loading doors are operated by two (2) pneumatic pistons located above the load doors. On 2 door dryers, the unloading doors on the back of the dryer will also be controlled by 2-pistons, located above the unload doors.

The 24 volt solenoid valve operators controlling the door pistons are located on the pneumatic plate in the rear of the dryer’s base. These solenoid valves are configured so that if power to the dryer is shut off, the door pistons ports are bled to the atmosphere so that the doors can be opened and closed by hand.

c.Optional Sprinkler Valve

The sprinkler water flow is controlled by a pneumatically operated water valve, which is located in the left side of the base. This water valve is controlled by a 3-port/2-position, 24 volt double solenoid valve which is located at the top of the dryer’s pneumatic plate. If no voltage is applied to both solenoids then ALL three 3-ports are blocked. This means that if the sprinkler is activated and power to the dryer is then shut off, the sprinkler will stay on, until the manual water valve is closed or until the dryer’s internal temperature drops below the sprinkler set point temperature and the sprinkler reset button is physically pushed.
