Disassemble and clean all parts
thoroughly; paint cabinet inside and out;
examine parts and repair or replace as
needed; use care in choice of cleaning
Use same procedures as for solution-feed
machine where they apply.
(1) D-Daily; W-Weekly; M-Monthly; Q-Quarterly; A-Annually;
V-Variable, as conditions may indicate.
(2) The frequencies shown are suggested frequencies that may be modified by local
command, as individual installation conditions warrant.
Check the Gas System. Check all piping and parts carrying
chlorine gas to verify that they are operating properly. Check flexible connectors at the
gas-supply containers. (To maintain a gas-tight seal, use a new lead gasket each time
a valve or tube is connected, including each time an empty chlorine cylinder is
replaced.) Remove and clean gas filters periodically. Check the heater each day to
make sure it is warm. See that metering devices, pressure reducing and shutoff valves,
hose lines, etc., work properly. Disassemble and clean when necessary, to determine
the cause of the fault. At the first sign of weakening, replace any faulty parts.
Clean the Cabinet and Critical Working Parts. Thoroughly clean
the chlorinator cabinet, glass parts, flowmeter, rate valve, vacuum regulator valve, and
other parts in which dirt may interfere with operations or make equipment unsightly.
Clean and cover unpainted metal that is subject to corrosion with a proper protective
Liquid Chlorine Evaporators. The chlorine vessel on the inside of the
evaporator and the water bath mechanism are the primary components requiring
maintenance. The chlorine vessel is subject to internal corrosion from chlorine and
external corrosion from the water bath. The chlorine vessel and the water bath are
normally cleaned and inspected every 2 years or after evaporating 250 tons of chlorine,
whichever occurs first. The sacrificial anodes in the cathodic protection system in the
