Servicing the Chemical Valves
CAUTION! If the suction line
exits your chemical tank through
a bulkhead fitting the tank
should be empty before
servicing the chemical fittings.
WARNING! Chemical fittings and
tubing contain chemicals.
Spillage and leakage will occur
when disconnecting fittings.
OBSERVE PROPER
PRECAUTIONS FOR THE
CHEMICALS BEING PUMPED!
If you have an Anderson injection point fitting
(Illustration 1) you may service the suction and
discharge check valves and Foot Valve/Bulkhead/
Flush Fitting, with the system under pressure, but
you should turn off the water flow through the
feeder.
To service the injection point fitting, or if there is a
failure of an injection point fitting, you must
remove pressure from the system (shut off the
water upstream of the unit).
Refer to the specific manual for servicing H.E.
Anderson IPFs available at
