EVAPORATION CHECKS

With the boiler running under normal load conditions, and the pump stopped having just completed
a refill cycle:
(a) Ensure that the boiler water level is correct.
(b) Switch the pump OFF at the pump interrupt / pump run switch.
The water level in the boiler will lower through natural evaporation. When the level nears the bottom of
the water level gauge sight glass, the first low water alarm will sound, the low water alarm lamp
will illuminate and the burner will shut down.
If it is required to check the second low water alarm, wait a further period for the LOW WATER RESET
switch to illuminate.
When the check is complete, proceed as follows:
(a) Switch the pump ON at the pump interrupt / pump run switch.
(b) Press the low water reset switch. The pump will start to refill the boiler.
If the pump starts to run at any time during the test then the test must be abandoned and restarted
from the beginning.
