Step 4: Connect the solenoid valve (optional) to the Stainless flexible hose

attached to the bottom of the Hallett. Do not bend the hose excessively. Make

sure the sealing washer is inside the end of the hose before making the

connection. The solenoid valve plugs into a polarized plug at the bottom of the

front cover near the power cord. The valve is a non-serviceable component

and nothing else should be plugged into this port. Secure the cable from the

valve to the wall. The solenoid valve is normally closed and must be powered to

open. The valve has a manual override (white lever) that can be used to force the

valve open should you require water for service/emergency purposes (note in the

event of alarm and shut down, complete disinfection of the water may not have

been achieved). In any regulated sites, the manual override should not be

used. For normal operation, always leave valve in automatic position. Test the

valve monthly to confirm valve opens and closes. Unplug valve from unit to

confirm water stops flowing.

Caution: Do not allow solder or solder flux to fall in or on the unit.

Step 5: Connect the remaining piping to the top Stainless flexible hose at the top

of the unit. Do not use PVC pipe or braided hose at the outlet – during periods

of no flow, water temperatures may exceed softening point of PVC. Metal pipe or

high temperature plastic pipe such as PEX, should be used after the flexible

hose. Make sure the sealing washer is inside the end of the hose before making

the connection. Do not bend the flexible hose excessively. Tighten securely.
