C6097A,B PRESSURE SWITCHES
OPERATION AND CHECKOUT
Operation
The manual reset C6097A diaphragm actuates the snap- acting switch to break a control circuit and lock out when pressure falls to the scale setting. The recycle C6097A models recycle automatically when the control circuit returns to scale setting plus differential.
The manual reset C6097B diaphragm actuates the snap- acting switch that breaks a control circuit and locks out when the pressure rises to the scale setting. The recycle C6097B models recycle automatically when the control pressure falls to the scale setting minus differential.
Manual Resetting
The C6097A manual reset models lock out when pressure falls to the scale setting and require manual resetting after the pressure rises to scale setting plus differential to resume normal operation.
The C6097B manual reset models lock out when pressure rises to the scale setting and require manual resetting after the pressure falls to scale setting minus the differential to resume normal operation.
To reset, once normal operating pressure is restored, push the reset button in as far as it goes, then release.
IMPORTANT
Lockout models cannot be made to recycle automatically by permanently holding in the reset lever.

C6097 Gas Fuel Application
1.Set cutoff pressure.
2.Open main supply line. Depress reset lever on lockout models until switch makes control circuit.
3.Set controller and limit switch to call for heat.
4.For C6097A: Close the manual gas shutoff valve. C6097 should open control circuit when pressure reaches cutoff point.
For C6097B: Open the manual gas shutoff valve, wait a few minutes for the pressure to rise; then lower the scale setting until the switch breaks control circuit and locks out.
5.For C6097A: Open the shutoff valve, return the pressure switch to its original setting and press the reset button (if necessary).
For C6097B: raise setting to normal and press reset button (if necessary).
6.Allow system to operate through at least one complete cycle to make sure all components are functioning properly.
C6097A Air Application
1.Set cutoff pressure.
2.Turn on fan.
3.Block fan inlet or filter area. Switch should break control circuit when pressure drops to cutoff point. Manual reset models lock out.
4.Remove obstruction. Press reset lever (manual reset models) and allow system to operate through at least one complete cycle to be sure all components are functioning properly.
