OPERATION allow pressure to build up. When pressure gauge reading approaches set point of pressure control, the switch will trip and shut off boiler. Turn off boiler. To reset pressure control, bleed off enough pressure in the boiler by opening steam outlet drain, or blowdown valve to allow the operating control to reset. 4. HIGH LIMIT PRESSURE CONTROL OPERATION The high limit is tested in the same manner but with the operating control set above the pressure setting of the high limit.
OPERATION OPERATION— Set the “BOILER PROGRAMMED DUTY” switch to “BOILER ON” if the boiler is to be shut down each night. Set it to “24-HOUR DUTY” if the boiler is to remain on continuously 24-hours per day (except during blowdown). Set the tabs on the large timer for the ON and OFF times desired for the boiler, screw in the small black day-skip tabs if is to remain off during the weekend, etc. If the boiler is on 24-hour duty, set the OFF tab for the time that is desired for blowdown.
OPTIONAL EQUIPMENT FOR STEAM BOILERS the motor runs, the wiper on the feedback potentiometer moves in a direction to balance the circuit. When the circuit is again in balance, the balancing relay contacts open and the motor stops. Similarly if the pressure of the controlled medium falls, the wiper on the controller potentiometer moves toward B, and the “open” contacts in the balancing relay make. The motor drives towards its open position until circuit balance is achieved.
OPTIONAL EQUIPMENT FOR STEAM BOILERS IF A CONTROLLER SEEMS TO OPERATE IMPROPERLY If the controller is suspected of operating improperly, it may be further checked as follows: 1. Leave the controller installed where it is, but disconnect all power to the boiler. 2. Loosen the cover screw below the main scaleplate and remove the cover. 3. Disconnect the wires from the controller. 4. Connect an ohmmeter between controller terminals B and W to measure the resistance of the potentiometer in the controller.

WATER FEED SYSTEMS B. The motor circuit should be wired into the pump control located on the boiler. See boiler instruction sheet for wiring diagram. C. All electrical wiring should be done by licensed electrician. D. Be sure to use the proper wire. Electrical wiring to boiler should be in accordance with National Electrical Code or local wiring code following wiring diagram supplied. Plumbing A. Connect water line to tagged fitting on the motor and pump assembly control feeder. B.
MAINTENANCE 7. When all (6) flange bolts are tight, connect all wires to terminals. Make certain wires are clean and bright to assure good electrical contact and nuts on screws are firmly secured. WARNING: Avoid use of chemical cleaning compounds. Follow maintenance instructions. 8. Open water valve so water supply can reach boiler feed mechanism. 9. Put main safety switch to “on” position. 10. Turn boiler to “on” position. 11.
