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.
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.
Automatic water feed is required on all CES Boilers: LOW PRESSURE FEED Note: Water Pressure feeds must be at least 10 psi greater than steam pressure. Low pressure water feed systems are used to supply make up water to the boiler where incoming water line pressure is 10 psig or greater than the operating pressure of the boiler.
W A TER FEED SYSTEMS Installation Wiring A. Check the voltage of the motor before making the wiring connec- tion. Some Chromalox boilers are supplied with dual voltage sys- tems. The motor should always match the voltage of the control circuit. B. The motor circuit should be wired into the pump control located on the boiler.
