Hallett 30 1” Instruction Manual

water, unplug the unit until the water supply can be restored. In the event of a

power failure, the unit will shut down and the solenoid valve will close, preventing

water from flowing. When the power returns, the unit will automatically restart

and perform a self-test. If no faults are detected, the unit will return to normal

operation and the solenoid valve will open. Note that even during a brownout, the

supply voltage may drop low enough to cause the unit to shut down. If the unit

does not automatically restart as described above, unplug the unit and plug it in

again.

Step 1: Plug the unit into the Transient Voltage Surge Suppressor. Connect the

surge protector to a GFCI. Flip the switch on the Transient Voltage Surge

Suppressor to ON position to start the lamps. Caution: Never look into or place

any exposed skin into the illuminated areas when the unit is operating.

Step 2: Once the unit is plugged in, all three lights will illuminate and an audible

alarm will sound. This verifies that the lights and the alarm are functioning. The

unit then performs a self-test. During this test, the alarm continues to beep and

the solenoid valve remains closed. The green light illuminates when the UV

lamps have reached full power and there are no system faults. New lamps may

take from a few moments to several hours to reach full power. Continue to

run the unit until the lamps reach full power. The optional solenoid valve will

then open and allow water to flow through the unit. This is the normal operating

mode of the unit. If the unit fails to start, unplug the unit and plug it in again.

Avoid continuously starting and stopping the unit within a 24 hr period, as this will

accelerate the aging of the UV lamps.

The self-cleaning feature of the Hallett system involves a wiper turning inside the

quartz sleeve. The wiper operates either upon power up of the unit or shortly

afterwards and then periodically afterwards. Pushing the Reset button for 1

second will also cause the wiper to operate for several minutes.

Seasonal Use and Shutting Down of Unit

Unplug the unit during extended periods of no water usage (four days or more),

as in the case of seasonal residences or during a vacation. If the possibility of

freezing exists, the unit and any filters must be drained. (See Draining the Unit.)

Upon returning, reconnect all fittings, close all valves and turn on water supply.

Plug in the Hallett and when operational, flush the water through the unit for at

least 5 minutes.

Caution: When the unit is not operating, the solenoid valve remains closed. If the

solenoid valve is forced open or if the optional bypass piping is used, untreated

water may enter the plumbing system. Emergency use of untreated water is the

only situation where the bypass piping should be used. Any water used for

drinking should be boiled. Unplug the unit if the bypass is used. Do not run the

unit dry. This will cause potential damage and scratching of the quartz

sleeve.

Disinfecting the Plumbing

Disinfection of the household or facility plumbing should be performed after the

Hallett has been installed and is operating. This procedure should also be done if
