Step 3: Two wall brackets, with two 1/4" slotted holes each are provided on the

unit. The unit should be secured vertically to a solid wall large enough to

cover the complete backside of the unit – See Figure 1D. Install the top two

fasteners (not provided) into the wall, and slide the unit onto them using the

slotted holes in the upper brackets. Then install the bottom two fasteners. Do not

install the unit horizontally. Leave clearance over the unit for lamp removal.

Connecting the Pipes

We recommend that a qualified plumber or certified technician perform the water

connections for your Hallett. Water must flow into the inlet at the bottom of

the unit. The outlet is located at the top of the unit. Install the valve upstream

of the unit.

Step 1: Shut off the water supply. Caution: Always turn off the water supply

before modifying or disconnecting any piping. Always open a faucet after shutting

off the water supply to relieve water pressure and ensure that the water has been

completely shut off.

Step 2: If you have decided to install an optional bypass line and drain, you may

begin to install these fittings at this point. See Figure 1B for more information on

how to connect optional bypass piping and drain.

Step 3: Connect the solenoid valve to the plumbing just upstream of the unit

(before the unit). Note the solenoid valve ensures that should the system fail, due

to power loss, color in the water or low UV lamp output, the system will fail in

safe mode and shut down the flow of water to your tap. The direction of flow

through the valve is important – verify flow direction with label on the valve.

Caution: over tightening a metal fitting into the valve will cause it to crack.
