Page 12: Operation
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. -
Page 13: Automatic Blowdown Instructions
If the boiler is on 24-hour duty, set the OFF tab for the time that is desired for blowdown. the ON tab can be ignored, but must remain on timer. - Page 14 SCR and, in turn energize the control relay. As the water level in the boiler drops below the level of the probe, the AC current is broken and the control relay is de-energized. The control will not energize until sufficient water is present in the boiler.
- Page 15 Solid State Progressive Sequencer The solid state progressive sequencer provides accurate elec- tronic control of multi-stage loads of the type used in Chromalox steam boilers. It features progressive sequencing (first on-first off) which equalizes the operating time of each load. This control gives visual indication of each energized stage by means of integral solid state light emitting diodes.

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. - Page 18 Boiler 1" Steam Equalizing Pipe Pump and Low 1-1/2" Water Control Normal Boiler Water Level Cutoff Level is Arrow Mark Blowdown Valve 1" Water Equalizing Pipe 2-1/2 REF.
