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 shutoff valve
before 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 or 1C for more
information on how to connect optional bypass piping and drain.
Step 3:
Connect the solenoid valve to the plumbing just upstream of (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. Do not over tighten.
Keep the coil of the valve pointing
upward (to prevent water from dripping on it). Water will not flow backwards
through the valve. See Figure 1D
Step 4:
Connect the solenoid valve 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 the right hand side of the unit where a port is provided.
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 it is
recommended you boil your water).
In any regulated sites such as municipal
applications, the manual override should not be used.
For normal operation,
always leave valve in automatic position. In the Setup menu of the Hallett, toggle
the valve to be “Installed” and a monthly reminder will appear to test valve.
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
extended periods of no flow, water temperatures may exceed softening point of
PVC if unit fails to purge. 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.
