Hallett 15xs Instruction Manual

clearances.

The Hallett is intended only for indoor use in a dry location. Should these

minimum installation recommendations not be met, the system will not operate

effectively.

The Hallett should be installed downstream of (after) any pre-treatment devices

such as filters, water softeners etc and also any pressure tanks. However, it must

be installed upstream of (before) any branches in the piping so that all the

water is disinfected before splitting and distributing throughout the home or

facility. If the plumbing system has a grounding lug or strap, this should also be

upstream from the unit, shutoff valve or filters. If grounding of the Hallett or

plumbing system is in question, please consult your local electrical inspector.

Time Required

Please note that full installation of the Hallett requires shutting off the main water

supply for a number of hours. If disinfection is necessary, all pipes must be

treated and flushed. Once the unit is plugged in, the new UV lamps may take

from a few moments to several hours to reach full power. Having a Lamp Alarm

is normal with a new system (or with newly installed lamps) until the lamps have

reached full power.

Summary of Installation:

Unpack and install Hallett on wall

Install top & bottom hose to unit and to plumbing

Install Shutoff solenoid valve

Install optional bypass & drain plumbing

Install purge valve discharge line to a suitable drain line

Connect system power cord to the Transient Voltage Surge Suppressor

Connect Transient Voltage Surge Suppressor to grounded power outlet

Assembling the Unit

Step 1: Unpack the unit, being careful to remove all packaging material. Inspect

the unit for damage particularly the quartz sleeve – See Figure 4A for

disassembly. Check if UV lamps fully inserted. Check & tighten the nuts securing

the top and bottom stainless manifolds - see Figure 4B.

Step 2: The Hallett has four keyhole slots for convenient mounting – all four

should be used. Do not mount the unit directly to an outside wall; mount on

plywood or shims – See Figure 1E. Do not install the unit horizontally.

Remove the top and bottom covers of the unit to make the mounting holes

accessible.

Step 3: Connect the Stainless flexible hoses to both the top and bottom of the

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

the connection. Tighten securely. Wrap the top hose with pipe insulation. (Not
