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 two (2) door models, the unloading doors on
the back of the dryer will also be controlled by two (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 dryers 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.
4. 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 dryers 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 dryers internal temperature
drops below the sprinkler set point temperature and the sprinkler reset button is physically pushed.
