Maintenance
Maintenance and care will depend upon the usage and environment in which the system is subjected to.
The following is the suggested regular maintenance required to keep the glycol feed system operating
properly:
TANK AND PLUMBING
Periodically check the piping and tubing to insure proper discharge of the glycol solution. The strainer
should be periodically checked for clogging and wear. The level wand should be removed and cleaned to
prevent clogging.
GEAR PUMP
Check for proper operation. If any pump/motor noises, leaks or changes in operation are detected, the
pump should be removed and examined by a certified technician. Gear pump repairs can be difficult and
should only be attempted by qualified personnel. Improper repairs or assembly can result in pump failure
and nullification of the warranty. No lubrication is required.
PRESSURE RELIEF VALVE
Periodic checking and replacement of the adjustment seal is the only maintenance required.
