Boiler blowdown controls and alarms do, however, require testing and inspection.
General guidance is given in Health and Safety Executive Guidancenotes BG01 and INDG436
in the UK.
8.3 General weekly maintenance:
-
Take a sample of the boiler water through a sample cooler, measure its conductivity
(calculate the TDS).
-
Check the conductivity controller calibration with the boiler at normal operating pressure.
-
Check that the blowdown valve shuts when the power is removed.
-
Operate any stop valves to ensure that they shut off, and move freely.
8.4 General six months maintenance:
-
Isolate the system (or with the boiler empty), remove the conductivity probe.
-
Clean the tip with fine abrasive paper / pad and wipe the insulation with a cloth.
-
Examine the control / solenoid / stop valves and other fittings.
-
Clean and refit or replace any parts necessary.
