Purge Valve, Hour Meter
Thermo-Sensitive Purge Valve
During times of no-flow, some UV systems will warm up, as there is no cool water
flowing through the chamber to cool the lamp. This is normal.
Increased temperature of the water means reduced UV output, as hot lamps do
not produce as much germicidal output as cool lamps do. This may result in the
UV system going into alarm state, if it is equipped with a UV Monitor.
The solution to this problem is to install a thermo-sensitive purge valve at the out
port of the UV system. It will automatically open and drain water from the cham-
ber, to allow cool water to replace it and maintain high UV output of the lamp. No
power is required.

Hour Meter
The electronic ballast of any Wyckomar UV system can be equipped with an op-
tional resettable hour meter, displaying the total run time of the lamp. This is
convenient for ensuring that the lamp is not used after the germicidal output has
decreased to less than 70% of the output of a new lamp (after 9000 hours of
operation).
