Replacing and Cleaning UV Lamps
The Hallett contains two ultraviolet (UV) lamps that emit high-intensity UV light in
the germicidal range, providing effective disinfection of the water flowing through
the unit. The lamps in your unit will decay over time and should be replaced
every 12 months for optimum performance. Avoid continuously starting and
stopping the unit within a 24 hr period, as this will accelerate the aging of the UV
lamps (note: however shutting down the system for seasonal use will extend
lamp life)
Your unit has an internal timer to keep track of the lifetime of the lamps. It will
issue a warning when the end of their lifetime approaches (see Troubleshooting
Guide).
The lamps can be replaced in a few minutes. Draining the unit is not required.
See Figure 3.
Caution: The lamps in the unit emit ultraviolet (UV) light that can cause
permanent damage to the skin and eyes. Never look at a lamp when it is
operating. Always unplug the unit before replacing lamps.
Caution: Never touch the bulb of a lamp with your fingers. Handle the lamp by its
ends only. If the surface of the lamp becomes dusty or dirty, use a clean lint-free
cloth and some rubbing alcohol to remove the dirt. For more difficult stains such
as water spots, use a scale remover to remove the stain and then rubbing
alcohol afterwards. The lamps are fragile and must be handled with care.
