AQUA-REX WK1 Installation, Operating, & Maintenance Instructions

& MAINTENANCE INSTRUCTIONS FOR
LOCATION
The best place to fit an Aqua-Rex physical water conditioner is on
the cold pipe where it goes into the water heater. Anywhere on the
cold supply pipe is also OK as long as it is after all filters and any
other water treatment system except UV.
The signal generated by Aqua-Rex travels both upstream and
downstream through the water thus treating all the water in the
home, even when fitted only to the water heater or softener loop.
You can fit it anywhere on the cold water supply and on any pipe
material; Copper, PEX, CPVC or PVC.

INFORMATION ABOUT COMMERCIAL SYSTEMS WITH
BOILERS AND HEAT EXCHANGERS. It is available as a
download from the website www.aqua-rex.com.
PUMPS
Pumps reduce the effectiveness of Aqua-Rex so always fit a unit
after a pump, never in front of one. In a home with a hot water
return we recommend installing Aqua-Rex on the cold pipe to the
water heater. On larger commercial systems, treat the cold service
with one unit and fit a second unit on the hot water return after the
circulation pump.
HEAT EXCHANGERS
Where pump fed heat exchangers are used, it is best to treat the
line from the heat exchanger to the storage tank. The signal travels
back into the heat exchanger at the hottest point.
LOW delta 't' WATER HEATERS BOILERS
Treat the return line from the heater to the storage tank, preferably
after the hot water return and cold make up water inlet.
FLEXIBLE CONNECTORS
These connectors can have spiral grooves or parallel grooves. On
a spiral groove just follow the grooves from the centre of the pipe
to the ends. You can't fit wires properly on parallel grooved pipe.
MAIN EARTH BOND
If there is a main earth bond close to the point of installation, make
sure the Antennas are downstream (after) the earth bond.
PIPE BENDS & VALVES
Antennas can be wound either side of a bend, a tee or either side
of a valve. (Twelve windings on two antennas requires 6 inches of
pipe run; four antennas need 12 inches)
INSTALLATION, OPERATING
WK1, WK1-E, WK2 & WK3
®
INSTALLATION
Fix the control box on the wall close to the pipe or hang it from the
pipe if the wall is too far away. The length of free wire between
the unit and the wrapped portion of the pipe should not exceed 15
inches. The aerials should not be under tension between the pipe
and the control box.
The WK2 and WK3 are supplied with two fixing lugs. Remove two
of the screws from the back plate and attach the fixing lug to the
back plate with the same screws.
ANTENNA WINDING
Antennas on all Aqua-Rex units are paired. They must
be wound in opposite directions going away from a
CENTRAL point. They must be tight on the pipe.
One antenna should start by passing behind the pipe and the other
antenna should pass in front. Secure each end of the antennas with
a cable tie.
DO NOT USE TAPE. SECURE BOTH ENDS PROPERLY. THE
WIRES MUST NOT BE LOOSE.
All four antennas of the WK1-E. WK2 and WK3 must be
wrapped around the pipe.
WK1-E WK2 and WK3 MODELS
Each of these units have two adjacent pairs of antennas. These can
be fitted to a single pipe, to two adjacent pipes or either side of a
heat exchanger.
ALL MODELS
Do not allow gaps between the antenna and the pipe. Windings
must be tight and close together except in the grooves of a flexible
connection.
Do maximise the number of windings per antenna, a minimum of
12. (WK3 minimum is 15).
