<strong>C6097</strong>A,B PRESSURE SWITCHESOPERATION AND CHECKOUTOperationThe manual reset <strong>C6097</strong>A diaphragm actuates the snapactingswitch to break a control circuit and lock out whenpressure falls to the scale setting. The recycle <strong>C6097</strong>Amodels recycle automatically when the control circuit returnsto scale setting plus differential.The manual reset <strong>C6097</strong>B diaphragm actuates the snapactingswitch that breaks a control circuit and locks out whenthe pressure rises to the scale setting. The recycle <strong>C6097</strong>Bmodels recycle automatically when the control pressure fallsto the scale setting minus differential.Manual ResettingThe <strong>C6097</strong>A manual reset models lock out when pressurefalls to the scale setting and require manual resetting after thepressure rises to scale setting plus differential to resumenormal operation.The <strong>C6097</strong>B manual reset models lock out when pressurerises to the scale setting and require manual resetting afterthe pressure falls to scale setting minus the differential toresume normal operation.To reset, once normal operating pressure is restored, push thereset button in as far as it goes, then release.IMPORTANTLockout models cannot be made to recycleautomatically by permanently holding in thereset lever.Checkout<strong>C6097</strong> Gas Fuel Application1. Set cutoff pressure.2. Open main supply line. Depress reset lever on lockoutmodels until switch makes control circuit.3. Set controller and limit switch to call for heat.4. For <strong>C6097</strong>A: Close the manual gas shutoff valve.<strong>C6097</strong> should open control circuit when pressurereaches cutoff point.For <strong>C6097</strong>B: Open the manual gas shutoff valve, wait afew minutes for the pressure to rise; then lower thescale setting until the switch breaks control circuit andlocks out.5. For <strong>C6097</strong>A: Open the shutoff valve, return thepressure switch to its original setting and press the resetbutton (if necessary).For <strong>C6097</strong>B: raise setting to normal and press resetbutton (if necessary).6. Allow system to operate through at least one completecycle to make sure all components are functioningproperly.<strong>C6097</strong>A <strong>Air</strong> Application1. Set cutoff pressure.2. Turn on fan.3. Block fan inlet or filter area. <strong>Switch</strong> should break controlcircuit when pressure drops to cutoff point. Manual resetmodels lock out.4. Remove obstruction. Press reset lever (manual resetmodels) and allow system to operate through at leastone complete cycle to be sure all components arefunctioning properly.65-0237—2 6
