blowdown valve:
If the pump is running:
1. Verify that the pump continues to run until the Pump Off level is reached and then switches
off.
If the pump is not running:
1. Lower the water level by opening the main boiler blowdown valve.
2. Verify that the pump starts to run when the water level reaches the Pump On level.
3. CLOSE the main boiler blowdown valve.
4. Verify that the pump continues to run until the Pump Off level is reached and then switches
off.
b) If the boiler is heating and under load, lower the water level by evaporation, observing a pump
cycle:
If the pump is running:
1. Verify that the pump continues to run until the Pump Off level is reached and then switches
off.
If the pump is not running:
1. The water level will lower through natural evaporation.
2. Verify that the pump starts to run when the water level reaches the Pump On level.
3. Verify that the pump continues to run until the Pump Off level is reached and then switches
