Low water cutoff
(if so equipped).
1. Float Type
a. Monthly Blowoff. During the heating season, if
an external fl oat type low water cutoff is on the
boiler, the blow off valve should be opened once
a month (use greater frequency where conditions
warrant), to fl ush out the sediment chamber so
the device will be free to function properly.
b. Annual Service. Float type low water cutoffs
should be dismantled annually by qualifi ed
personnel, to the extent necessary to insure
freedom from obstructions and proper
functioning of the working parts. Inspect
connecting lines to boiler for accumulation of
mud, scale, etc., and clean as required. Examine
all visible wiring for brittle or worn insulation
and make sure electrical contacts are clean
and that they function properly. Give special
attention to solder joints on bellows and fl oat
when this type of control is used. Check fl oat
for evidence of collapse and check mercury bulb
(where applicable) for mercury separation or
discoloration.
2. Probe Type (Annual Service). Probe type LWCO
should be removed once a year, examined and
cleaned of any dirt accumulations to assure proper
operations. Do not attempt to repair mechanisms
in the fi eld. Complete replacement mechanisms,
including necessary gaskets and installation
instructions, are available from the manufacturer.
