Control Valve
Operation
Maintenance
Directs air to open or close the recirculation valves. Control of the valve is
either automatic or manual depending on the mode of operation. For set-up
and trouble shooting purposes, the valve can be operated externally by
manually depressing the override button. Turn clockwise to lock in place.
There is no normal operating maintenance required; however, to assure
trouble free operation, it is necessary to operate the valve with a clean air
supply.
