ITEM DETAILS
Plumbing
Leaks Visually check DI water lines outside of heater cabinet for signs of leaks at the
connections. (A leak sensor will detect leaks, but this periodic visual check is
recommended.) Also, visually check bottom of cabinet inside heater module
enclosure for DI water leaks. Tighten fitting(s) if necessary. If heater module
is leaking, contact Trebor for instructions.
Overpressure
Relief Drain &
Diaphragm Visually check the drain line for water running from the heater. The
overpressure burst fitting can start leaking if the system has experienced
pressures above 60 PSIG. The burst fitting can be checked by inspecting the
relief port at the back of the cabinet. No water should be present in the relief
drain since it is required to be plumbed to an open drain. If water is present in
the drain plumbing, the fitting should be replaced.
General
Electronics Visually check electronics inside control enclosure for any signs of
overheating, deformation, or corrosion.
Solid State
Relays The SSR’s should be free of corrosion at the terminals and should not have
signs of overheating or deformation. The wires attached t
o the SSR’s should
be clean and in good condition. Check and tighten mounting screws for
optimum heat transfer to heatsink.
