3 Intended use
3.1 Notes on product warranty
Any non-designated use of the device can impair its function and the pro-
tection provided. This leads to invalidation of any warranty claims!
Please note that liability is on the side of the user in the following
cases:
nThe water sampling station is operated in a manner which is not con-
sistent with these operating instructions, particularly safety instruc-
tions, handling instructions and the section "Intended Use".
nInformation on usage and environment (see section 5 „Technical
data“ on page 12) is not adhered to.
nIf people operate the device who are not adequately qualified to carry
out their respective activities.
nUnauthorised changes are made to the device.
3.2 Intended purpose
The EASYPRO water sampling station is solely designed for sampling and
control applications in the treatment of swimming and bathing water in
swimming pools and whirlpools not operated in accordance with DIN
19643, as well as for the treatment of process water. The operational
safety of the product supplied can only be ensured if used according to
their purpose.
All other types of use are prohibited and will invalidate the warranty.
The controller on the water sampling station monitors the current meas-
ured values during water treatment and controls the dosing systems con-
nected for water treatment. In this way, the controller ensures constant
water values in various applications and can be deployed universally. Its
main application is to maintain the quality of water by evaluating the
measurements of chlorine value, pH value and Redox value as well as
conductivity.
3.3 Foreseeable misuse
The following section provides information regarding the device applica-
tions which are classified as non-intended use.This section is intended to
allow you to detect possible misuse in advance and to avoid it.
Foreseeable misuse is assigned to the individual stages of the product
lifetime:
3.3.1 Incorrect assembly
nConnecting the mains voltage without a protective earth
nNon-fused or non-standard mains voltage.
nNot possible to immediately or easily disconnect the power supply
nWrong connecting cables for mains voltage
nSensors and actors connected to the incorrect terminals or incorrectly
configured.
nProtective earth removed.
3.3.2 Incorrect start-up
nCommissioning with damaged or obsolete sensors.
nCommissioning without the establishment of all protective measures,
fastenings etc.
3.3.3 Incorrect operation
nProtective equipment not functioning correctly or dismantled
nUnauthorised modification of the controller.
nIgnoring of alarm or error messages.
nThe elimination of alarm or error messages by insufficiently-qualified
personnel.
nBridging the external fuse
nDifficult operation due to insufficient lighting or poor access to the de-
vice.
nOperation not possible due to dirty or illegible display.
3.3.4 Incorrect maintenance
nCarrying out maintenance during ongoing operation
nNo adequate or regular inspection of correct functioning
nNo replacement of damaged parts or cables.
nNo securing against reactivation during maintenance work
nUse of the wrong spare parts.

ing components are available for the product. The scope may be less for
this version.
nBase plate with LED lighting for the valves
nMulti-channel controller TOPAX®MC
nSample water filter
nFlow controller with integrated temperature sensor
nFlow control
nMeasuring cell fittings
nBuffer solutions for adjusting each measuring cell
The measuring cells are packaged separately and not pre-installed.
4.2 Design and function
The water sampling station can continuously measure the level of disin-
fection (effective chlorine content), the pH value, the Redox value, the to-
tal chlorine content, conductivity and the sample water temperature. This
water sampling station can therefore be used in the water treatment of
public swimming pools, brine baths, hot-water installations and industrial
water treatment to control connected systems and control points.
Depending on the version, the water sampling stations are fitted with the
relevant measuring technology and a TOPAX®MC controller.

Pulse frequency
nRelay: 10 – 100 pulses per minute
nOptocoupler: 10 – 350 pulses per minute
nThe pulse frequency is dependant on the control deviation and the set control
parameters. With a control output power of Y = 25 % and a maximum pulse
frequency of 100 pulses/min., the controller would output 25 pulses/min.

nDepending on the control deviation and the defined control parameters, the relay
pulls in or drops out for the set cycle duration. If the cycle lasts 30 seconds and the
controller output power is 40 % the relay applies for example for 12 seconds,
followed by 18 seconds of non-application.

Water sampling station EASYPRO Operating instructions
7 Installation
7.1 Installation location of the water sampling station
EASYPRO
This section takes you through the installation step by step. The following
criteria must be taken into account when selecting the assembly location:
nThe installation surface is even.
nThe installation height is chosen so that the display of the controller is
at eye level for the user.
nBelow the water sampling station there must be at least 20 cm free
space to route the inflow and outflow pipes.
nAll lines and cables must be routed without kinks.
nThe sample water must reach the water sampling station from the ex-
traction point in as short a distance as possible in order to avoid
measured value deviations.
nAvoid direct sunlight or heat radiation.
7.2 Wall mounting
Resources required:
@Mounting set
@Drill
@Phillips screwdriver
The position of the fastening point is to be inferred from the dimensioned
drawings in chapter 6 „Dimensions“ on page 18. All 6 drill-holes have
to be used. The wall panel is clamped on the mounting bolts between two
nuts with washers. The unevenness of the wall can be levelled out by ad-
justing the nuts until the wall panel is kept level and free from tension.
Fig. 12: Wall mounting
7.3 Installing the hydraulics
This section takes you step by step through the installation of the hose
connections to the water sampling station.
PLEASE NOTE
Hydraulic distortion of the measurement results
Incorrect installation of the hydraulic lines can distort the measurement
results. As a result, the controlling of connected systems and control
points may be faulty.
ðComply with all the guideline instructions for installing the water
sampling station and connected products.
ðOnly use hose connections made from polyethylene (PE) with a di-
ameter of 6/8 mm.
ðPrevent misrepresentations of the sample water en route to the
water sampling station by taking the sample water 30 cm above the
bottom of the tank or in the centre of the water pipe. The extracted
sample water must reach the water sampling station within a short
space of time, thereby arriving with a pressure of 0.2 bar.
ðIf the extraction or supply of the sample water does not satisfy these
requirements, an external sample water pump must be installed
before the water sampling station.
ðIf you expect heavy soiling (e.g. leaves,coarse, small floating mate-
rials,etc.) in the sample water,use an external pre-filter.It helps you
prevent blockages in the water sampling station.
Pre-conditions for actions:
ü
The wall mounting and electrical installation have been successfully
completed.
Perform the following work steps:
1. Connect the extraction point of the sample water to the inflow tap
(Fig. 2 „Water sampling station EASYPRO 4“ on page 10, pos. 5) by
plugging the hose into the inflow tap.
2. Connect the return-flow hose of the sample water to the outflow tap
(Fig. 2 „Water sampling station EASYPRO 4“ on page 10, pos. 12)
by plugging the hose into the outflow tap.
ü
The hydraulic of the water sampling station have been
successfully installed.
