After proper wiring and piping of boiler system is complete, testing of controls can start. Before testing controls, it is recommended that all contactor fusing be removed. This is to prevent possible element failure under test conditions. A. OPERATING AND TESTING THE McDONNELL & MILLER LOW WATER CUTOFF CONTROL.
B. ADJUSTING OPERATING PRESSURE CONTROLS 1. Chromalox boilers are supplied with operating and high limit pres- sure controls. One is used for controlling the operating pressure of the boiler while the other is used as a high limit control. To deter- mine the difference in the controls, the high limit has a manual reset lever on top of the case.
OPERA TION AUTOMATIC BLOWDOWN INSTRUCTIONS (IF FURNISHED) The Automatic Blowdown is a device which automatically starts up your boiler in the morning; shuts it down at night and blows down (partially drains) the main boiler drain and the low water cut-off col- umn for a predetermined time interval each working day.
OPTIONAL EQUIPMENT FOR STEAM BOILERS AUXILIARY LOW WATER CUTOFF Operation Operation of this control is accomplished by sensing a minute AC current flowing between submerged contact probe in the boiler shell.
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.
HIGH PRESSURE FEED High pressure makeup water pumps are used when water pressure does not exceed boiler pressure by more than 10 psi and when con- densate water is not returned to the boiler. Note: Consult factory or sales office for motor/pump sizing for appropriate water feed system.
30 Gal. Condensate Return System W A TER FEED SYSTEMS CONDENSATE RETURN SYSTEMS Chromalox condensate return systems are used wherever condensed steam can be collected for reuse in the boiler. Significant energy can be saved by returning condensate to the boiler.
