Water sitting in UV reaction chamber
and heating up due to infrequent use
Run tap for a short period of time.
Unit leaking water
Misaligned or cross-threaded
connections on inlet/outlet ports Reinstall to ensure a solid connection with ports. Inlet/outlet threads on
UV chamber are NPT type and require thread sealant.

spikes
Install a water hammer arrestor in system.

is not coming on (visible/audible
alarm activated)
Lamp not installed correctly Ensure lamp is installed correctly with electrical fitting (must be snug).
Lamp failure Replace UV lamp.
System is vibrating
Not mounted securely Secure fasteners.
Water hammer* causing vibrations Install a water hammer arrestor in system.
Excessive heat generated
Not being allowed sufficient space for
cooling
Clear space for cooling (min. 6-12” / 15-30 cm clearance around unit).
Operated in an excessive ambient
temperature
Unplug unit until temperature is within ambient operating conditions.

*Water hammer: Sudden closure of a control valve or stopping of a pump produces excessive pressure surges in a pipeline. These pressure surges can
cause significant damage to equipment and/or appliances directly attached to the water line. Water hammer is usually noted due to the characteristic
banging sounds when valves on the line are suddenly closed. Water hammer conditions must be immediately remedied, and damage to systems as a result
of this condition are not covered under warranty.
