Field Controls Water System CW HD 2 User Manual

CLEARWAVEWATER CONDITIONER  
MODEL CW-HD-2  
The ClearWaveis the most advanced hi-tech computerized anti-scale device available today. It  
operates by using a programmed ‘chip’ to constantly cycle through and induce over 200 different electro-  
magnetic low frequency wave pulses into the water. These wave pulses produce water with remarkable  
anti-scale properties, without adding salts or chemicals, at an operating cost for electricity of  
approximately $25.00 per year.  
POWER SPECIFICATIONS: 18 VAC, 25 Watts, .22 Amps  
HOW IT WORKS  
Pure water contains nothing but H20. But water, as it comes out of the ground, is rich in a multitude of  
minerals. Minerals such as calcium and magnesium are the main components of hard water, and the  
cause of scale formation and other problems.  
There are three basic methods used to control the problem of hardness and specifically scale  
formation.  
ION EXCHANGE:  
One method is to remove the calcium and magnesium from the water through ion exchange (the  
traditional water softener). This method requires the use of a resin filled tank with a high concentration of  
salt ions. As the water flows through the resin tank the salt ions (typically sodium) are exchanged for the  
calcium or magnesium ions. This lowers the concentration of the minerals that cause scale and therefore  
inhibits scale formation.  
CHEMICAL ADDITION:  
A second method used to control hard water scale is the addition of chemicals (such as phosphates) to  
the water. These materials chemically alter the scaling characteristics of the calcium or magnesium,  
allowing the concentration of the minerals to stay the same while still reducing scale formation and its  
affects.  
Both of the above methods require the use of consumable materials to change the makeup of the water.  
For these devices to function properly, the homeowner must continuously replenish the salts or chemicals  
as well as perform periodic maintenance on the equipment. In addition to these inconveniences, the  
chemicals and salts discharged into the effluent water present problems downstream to the municipal  
water treatment facility and the environment. Many U.S. cities have been enacting and/or evaluating  
environmental legislation to limit or reduce the levels of chemicals or salts that result from these types of  
water treatment methods.  
ELECTRIC POTENTIAL:  
A third method used to treat the hard water problems associated with scale utilizes changes in electrical  
potential in the water to produce the affects of chemical addition. The electric potential applied changes  
the scaling characteristics of the calcium or magnesium without the removal of these ions or the addition  
of chemicals.  
 
INSTALLATION  
WHERE TO INSTALL THE CLEARWAVE™  
1. For water supply applications, locate where the main water supply pipe enters the home or  
building. Point of use applications such as dishwashers, ice makers, boilers, water heaters  
etc., attach the ClearWave™ unit to the water supply line to that particular appliance. For  
long system piping lengths or high level calcium water, mount a CW-HD-1 to point of use  
appliances.  
2. Find a suitable location to install the ClearWave™ on the water supply pipe before the  
piping branches off to supply water throughout the building.  
HOW TO INSTALL THE CLEARWAVE™  
1. One set of mounting brackets are provided, for mounting the ClearWave™ onto 1-1/2 inch  
to 4 inch water pipes or wall mounted near the selected pipe area. Mount the mounting  
brackets to the base of the ClearWave™ by using the screws provided. Mount the  
ClearWave™ onto the pipe with wire ties or to the wall with appropriate fasteners. (see  
Figure 1) For pipe mounting, the wall mount tabs should be removed from the mounting  
brackets. (see Figure 2)  
2. Plug the antennas into each end of the housing, to the appropriate wire wrap connections  
(e.g. “CW” for clockwise wrapping and “CCW” for counter clockwise wrapping). If longer  
wires are needed, up to 50 feet of 12Ga stranded wire can be added to the antenna wires  
with an insulated butt end wire connector or they can be replaced with 60 feet of 12Ga  
stranded wire.

PROPERLY WRAPPING THE ANTENNAE  
The antenna wrap around the water pipe on each end of the ClearWave™ (see Figure 1). A  
minimum of seven fully wrapped coils of the antenna wire, with each coil wrapped tightly against  
the pipe and pressed snugly against each other is required for best results (see Figure 1A).  
Each wire coil should be spaced 1 inch to 2 inches apart. The operation of the ClearWave™  
and the antenna installation is not based on direction of water flow, but one antenna MUST be  
wrapped in a clockwise direction and the other wrapped in an counter-clockwise direction.  
1. On the right side of the unit wrap the first antenna onto the water pipe by securing the “CW”  
clockwise antenna to the water pipe next to the ClearWave™ housing with a wire tie. Wrap  
the right antenna clockwise (over the top of the pipe first), keeping the antenna wire tight  
against the pipe and the preceding coil. Secure the end of the antenna wire to the water  
pipe with a wire tie (see Figure 1A). Repeat wrapping the remainder of the antennas onto  
the pipe alternating the wrap direction (see Figure 1).  
2. On left side of the unit wrap the first antenna onto the water pipe by securing the “CCW anti  
clockwise antenna to the water pipe next to the ClearWave™ housing with a wire tie. Wrap  
the antenna counter-clockwise (Under the bottom of the pipe first), keeping the antenna wire  
tight against the pipe and the preceding coil. Secure the end of the antenna wire to the  
water pipe with a wire tie. Repeat wrapping the remainder of the antennas onto the pipe  
alternating the wrap direction (see Figure 1).  
3. When energized, the ClearWave™ by plugging in the power supply, the modulation  
indicator lights start flashing sequentially indicating that the ClearWave™ is functioning  
properly. If the indicator lights do not flash sequentially, unplug the power supply, wait one  
minute then plug in the power supply again. If at any time a functional problem is  
suspected, unplug the power supply, wait one minute then plug in the power supply again.  
NOTE: The performance of the ClearWave™ is not affected by the direction or orientation of the unit.  
The unit may be mounted to horizontal, vertical, or diagonally. The ClearWave™ can be used effectively  
on any type of water pipe; galvanized, copper, or plastic.  
NOTE: The ClearWave™ is designed and tested to cause little or no interference to other  
communication devices, such as televisions, and most cordless telephones. Install the ClearWave™ at  
least ten feet from any radio, television, or cordless telephone base unit to eliminate possible interference.

OPERATION TIMETABLE FOR THE CLEARWAVE™  
The following timetable of events should be used to evaluate the operation of the ClearWave™ during the  
180-day customer satisfaction period. This is the best way to evaluate the ClearWave™ operation and  
benefits the ClearWave™ technology can provide for you and your home. Please note testing for  
changes in hardness with current testing practices will not show you if the ClearWave™ is working. The  
current practice of determining water hardness is the measurement of the concentration of calcium and  
magnesium in the water. Since the ClearWave™ does not remove any calcium or magnesium ions from  
the water, testing the water before and after the installation of the ClearWave™ will not show any change.  
DAY 1:........................................The ClearWave™ action immediately starts to loosen existing scale in  
both the hot and cold water systems. One should find soap lathers more easily.  
DAY 5 and onwards: ..................Scale begins to break down and come off water heater elements  
(immersion heaters) and tanks. Most particles are microscopic and will flow through your water system,  
but some small particles may be seen in the water coming from the hot water tap.  
DAY 10 to 16:.............................It should be noticeably easier to wipe clean ceramic, plastic, glass, and  
metal surfaces. By now the quantity of bath soap, dish soap, laundry detergent, and laundry softening  
agents can be reduced. Scale should have loosened on faucet, showerheads and frequently used  
appliances that boil water (such as coffee makers).  
DAY 16 and onwards: ................Scale should continue to loosen from faucet, showerheads, and pipes.  
With the continuing break down and reduction of scale from the heating surfaces of water heaters, water  
should heat up quicker using less energy to achieve the desired temperature.  
After 1 to 2 months:....................Any scaly crust or stains in toilets or under faucet should be significantly  
reduced. No new stains or crust should form. Mold that attaches to scale will begin to disappear from  
shower curtains and once cleaned should not reappear. Depending on the water hardness in the area,  
the full affects can take up to 12 weeks, especially if the system has been heavily scaled up over many  
years.  
NOTES:  
1) If iron is present in the water supply, use an iron filter prior to the ClearWave™.  
2) Depending on water hardness or water make-up, two CW-HD-2 units may be required.  
3) The CW-HD-2 can be used on water up to 25 grains of hardness. If over 25 grains, it can be  
used to aid the operation of a water softener.
