Application of AntiCa
++
devices
AntiCa++ devices are intended to protect:
• Boilers and heat generators
• Home appliances and domestic hot water heaters, including gas-fired instant hot water
systems, eliminating expensive maintenance of heating elements
• Heat exchangers, converters, water distribution systems, heating district distribution
systems, generation of hot water, hydronic systems
• Process equipment and systems in which the formation of scale takes place as a result of
temperature or pressure changes in hard water.

Performances
The high performance of AntiCa++ devices in hard water applications is because they are
designed, manufactured and installed in consideration of the following parameters:
• chemical composition of the treated water
• the pipe diameter where the device is being installed
• volume of water or water velocity flow through the pipe where the device is being installed
• pipe material where the device is being installed – metal or plastic
Description of AntiCa

devices
AntiCa
++
devices consist of:
• electronic unit
• power coil cable (red)
• circuit for control level based on flow signal from flow meter ( EUV xx AI )
• circuit for level switching through timer ( EUV xx T a TI )
• circuits for manual switching based on flow ( EUV xx MI )

• power ON – red LED diode marked "POWER"
• power to coil cable (red) - green LED diode marked "DESCALING"
• control based on water volume flow EUV xx AI

the output circuit
AntiCa++ location and installation
Install AntiCa++ device upstream of the process device that needs to be protected against
scale formation.
Install the device downstream of open-to-atmosphere water reservoir or tank. The installation
upstream of the water reservoir or tank open to atmosphere is not recommended. The
treated water open to atmosphere even for a short period of time loses the benefit of
Electronic scale eliminator ANTICA++

treatment and is rendered useless. However the installation of the device in open water
circuits downstream of the reservoir or holding tank is beneficial.
In closed water circuits the installation of the device upstream of the holding tank is highly
recommended. When the device is installed upstream of the holding tank, then the tank doubles
as a sedimentation vessel where the scale separates from the water. The sediments can then be
flushed out of the system. However, if thus treated water is not used within 48 hours the
treated water reverts to the raw supplied water state and needs to pass again through AntiCa++
device to protect the system.
If in doubt of the device placement in the systems consult with the manufacturer or his
representative.
Basic requirements:
Before installing the device on the designated pipe, determine the hardness of the raw water
in pH. Where possible determine the amount of iron (Fe) in the raw water. From the water
hardness analysis consult Table 1 below and install the number of coil windings indicated. If the
water hardness is greater than 40°dH, then it is necessary to order a special device.
For devices EUV xx Dom, D and T wind the number of coil windings as indicated in Table 1
Total water
hardness °dH
<16 16 - 24 24 - 32 32 - 40 > 40
Number of coil
windings (2x)
11 12 13 14 15
In case the water hardness cannot be determined then it is recommended to install 2 x14 coil
windings.
For devices EUV xx MI, TI and AI wind 2x11 coil windings with the separation distance
between coils shown in Table 2 below in metric
DN of piping [mm] 50 - 65 80 - 100 125 - 150 200 - 250 300 - 500
Distance L [mm] 200 250 300 500 800
For devices EUV xx MI, TI and AI wind 2x11 coils windings with the separation distance
between coils shown in Table 2 below in imperial units
DIA of piping [in] 2 – 2 1/
2
3 - 4 5 - 6 8 - 10 12 - 20
Distance L [in] 8 10 12 20 32
For devices EUV xx MI and TI set up the strength of signal:
• in accordance with the table printed on the side panel of the device for water hardness up
to 20°dH
• one step up for water hardness between 20 - 30°dH ( eg. from 7 to 8 )
• two steps up for water hardness between 30 - 40°dH ( eg. from 6 to 8 )
• for water hardness above 40°dH it is necessary to consult on the settings with the
manufacturer or his representative and/or order a special device
Note:
• When the water analysis reveals that the iron (Fe) content is Fe>1 mg/l and pH <6.5 or >8.3
it is necessary to consult on the device settings with the manufacturer or his representative.
Installation:
1. Fasten the device to the wall with the supplied screws at a distance of 1,5 m max from the
installed coils on the pipe that is intended for protection.
• For devices EUV xx MI, TI and AI screw in the plastic hanging eyes supplied.
• For devices EUV xx T and TI install and connect the timer (when timer is part of the supply).
Electronic scale eliminator ANTICA++

• For devices EUV xx AI connect to water volume measuring device.
2. From supplied power cable (red), wind on vertical or horizontal straight pipe 2 coils with the
number of turns indicated in Table 1 and the distance between them indicated in Table 2.
Please note that both windings must run in the same direction as shown on the installation
diagrams for each type of the device.
• Secure the start and finish of each coil winding with the supplied wire ties to the pipe so
the remaining length of both ends of the remaining power cable (red) are approximately of
the same length.
CAUTION!
Wind coils in numbers and direction shown on page 4, Table 1, with the correct distance
between coils, Table 2, on a straight pipe following the distances from fixtures or tees shown on
Device installation. Follow the recommendation of minimum distance to pipe fittings or tees
from the end of the coils that need to be greater or equal to 3 x OD of the pipe where the coils
are installed. Pay attention to the fact that the minimum distance to other parallel piping
should be 2 x OD minimum.
3. After installing the desired numbers of windings at the correct distance between them,
wound in the same direction, secured with cable ties to the pipe, connect the power cable
(red), to the plugs on the Device. There is no preference as to the polarization, hence it is
not designated which end is plugged into the device’s connectors. However pay attention to
piping material, “Metal” or “Plastic” on devices EUV DOM, D, T as the proper function of the
device is dependent on the type of pipe material on which the coils are installed.
4. Plug the device into an electrical wall outlet. All control LEAD lights on the device will light-
up.
5. Program the timers as indicated in the manual for devices EUV xx T and TI.
6. For EUV xx MI and TI program the water meter in accordance with the side panel of the
device.
7. Change the setting to position „A“ for EUV xx AI device.
Checking the function of AntiCa++ device
Considering the fact that AntiCa++ devices change only the physical properties of the treated
water (formation of aragonite crystals), the functioning of the device can be determined
indirectly. If the water hardness upstream and downstream of the installed AntiCa++ device is
the same as it is downstream of the protected equipment (hot-water heater, exchanger, etc.),
no scaling of the equipment takes place.
When the device is installed on older systems that were not protected and scaling has already
taken place, then during system de-scaling the hardness of exiting water may be higher than the
initial hardness of water entering the system, indicating de-scaling is taking place. It is possible
to estimate the intensity of system de-scaling from the difference in hardness of systems outlet
and outlet of AntiCa++ device. It is possible to regulate the rate of the system cleaning process
by changing the level of the AntiCa++ device output signal.
If the water hardness exiting the system is lower than that measured after the AntiCa++ device,
sedimentation in the system has occurred and cleaning of the system must be scheduled.
In cases where the AntiCa++ device is installed on an electric hot water boiler that was not
protected before and has been in use for some time, the boiler must be de-scaled before the
AntiCa++ device is installed. If de-scaling is not done before installing the device the softened
scale may fall down from the boiler’s wall and damage the heating elements.
Operation and maintenance of AntiCa++ devices.
The devices do not require any special operation or maintenance. Operations consist of
routine checking of LED lights, which indicate the functioning of the device. If one of
the
LED lights is OFF, it may indicate power failure or that the device is not plugged in or that the
device is faulty. In the case of a faulty device contact the manufacturer or his representative.

Considerable effort should be made to monitor the system where the AntiCa++ device is
installed. On older systems where scaling took place before the AntiCa++ device installation, the
treated water softens the scaling and in time may restore the system to its original state.
Depending on the severity of system scaling, the loose scale in piping systems with reduced flow
velocity can settle in any place and invoke system blockage. Therefore flushing of the system
must take place. Install dirt pockets with valves to drains in piping if this was not done in the
original installation.
Closed systems with low pressure and low flow should be flushed regularly till the sediments are
not visible in flushed water. Aragonite crystals could in this environment produce sediment like
powder dissolved in water, thus flushing of the system must take place to remove them.
