5. MAINTENANCE

Test Shutoff Valve Monthly

The Optional Solenoid Shutoff valve should be tested monthly to confirm it opens

and closes. Unplug valve from unit to confirm water stops flowing. Plug the valve

in again to confirm water continues to flow.

Clean Air Filter Periodically

The Hallett contains a washable air filter in the blower housing panel (See Figure

1H). Periodically check and clean the filter to ensure blower operation is not

impeded.

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 amount of life remaining on the lamps is measured in hours and can

be seen in the main section of the menu.

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 (quartz portion) 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.
