1 Installingthe pH FUN
Perform all installation workcarefullyand complywith the applicable safetyregulations.
Important:
In addition, complywith the applicable regulationsregarding the installation of electricaldevices.
During installation, disconnect the measurement, control and dosing device and all other
electrical loadssuch as the electrical heating or the circulating pump fromthe mains.
1.1 General notes on installation:
•Ensure that the hoses are laid without kinking and that chafing cannot occur.
•Avoid laying the hoses over sharp edges.
•Carefully connect all hoses and check that the connections are firmlyattached.
•Avoid unnecessarilylong hose lengths.
•Do not guide the hosesdirectlyoverheat-conducting pipes orsystems.
•Checkthat the float in the measurement chamber can float freely.
•Adjust the water flow through the cellso that the float just barely lies against the upperend in its guide bore.
•Ensure that connections and hose connections are tight.
1.2 Selecting the installationlocation
To mount pH FUN, select a dry, frost-protected, sheltered and level location on a vertical wall. Ensure that the area is
readilyaccessible and well-ventilated. There should be no energised electrical cables, contactors, electricmotors, etc.
in its vicinity. The installation location should be asclose as possible to where the measurement water is extracted and
returned.
1.3 Mountingthe pH FUN on the wall
•The base plate with the mounted controllerand measurement cellcan be used asa drilling template byholding
it up against the mounting location and marking the drill holeson the wall.
•After the holeshave been drilled in the wall, securelyattach the pH FUN to the wall using suitable countersink
screws.

1.4 Installing the measurement watercircuit
•Place the measurement water extractorand return asshown in the installation plans(see Chapter 2.8). To do
this, use saddle clampsinto which you then screw in the measurement waterextractor and measurement
waterreturn.
•Connect the measurement water extractor and prefilterat the measurement chamber ofthe pH FUN using a
piece of measurement waterhose.
•Connect the measurement water return and output of the measurement chamber ofthe pH FUN using a
section of measurement waterhose.Electrical connection
The systemhas been designed and constructed according to the applicable regulations. It was carefullyinspected
before leaving the factoryand left the factoryin a perfectlysafe condition.
The equipment can onlybe operated safely if all of the instructions contained in this manualare followed. The
equipment should be installed bya licensed electrician.
The supply voltage forthe device maynot exceed 240V/50 Hz. The allowable operating temperature range isfrom0 to
50OC, and the allowable humiditylevel equals 0-90%.
Ensure that all plug-in connections are protected against water, asisstandard practice for electrical connections.
Danger warning:
For safetyreasons, the pH FUN should be connected in such a wayso that it isonlysupplied with
current when the circulating pump isrunning. Together with the float switch in the measurement
cell, thisensuresthe maximumamount of operationalsafety. It is thusimpossible for the dosing
pump to dose pH-Minus(pH-Plus) into standing water.

1.5.2 Earthing of the pHvalue measurement
Measurement water extractor and return are each provided with an earthing. These earthings ensure that any
interfering electrical potentialsthat maypossiblybe present in the pool water are safelydiverted.
Note:
The supplied earthing of the measurement waterextractorand return MUSTbe installed. This
earthing MUSTbe run to a separate secure earthing.
Always ensure that fault current is not flowing into the water of the swimming pool. Professional
measurement is recommended.
1.6 Connecting the dosing line for pH-Minus
Connect the supplied pH pressure line on one side with the pressure side (right connector)ofthe vacuumpump.
Connect the otherside with the injection piece at the measurement cell (onlyBAYROL pH-Minus; BAYROL pH-Plus is
directlydosed in the circulating line via an injection piece, see following chapter).
Connect the suction line which is located on the suction lance with the suction input (left connection)of the dosing
pump.
Ensure that all connectionsare tight and securelyfastened.
1.7 Dosingof pH-Plus (increaseof the pH value)
Danger warning:
Should pH-Plus be utilised for increasing the pH value instead ofpH-Minus for reducing the pH
value, the pH-Plus maynot be feed into the measurement cell, it must be fed directlyinto the
circulating line.
You willrequire the following accessories(available at your BAYROL dealer):
•100 509 PEhose (length depending on the installation situation)
•171 207 Injection piece 0.5 bar (1 piece)

2 Puttingintooperation
Before putting the systeminto operation, all previouslydescribed stepsmust be performed and the conditionsspecified
there must be met!
Then proceed as follows:
•Insert the suction lance into the full canister with pH-Minus(pH-Plus) and tighten the screw connection firmly.
Ensure that the tip ofthe suction lance with the switch islocated at the verybottomofthe canister.
•Connect the BNC connectorsof the suction lance with the socket on the lowerside controller (see also Chapter
1.5.1 Connections on the controller housing
•Connect the pH FUN to the mains(connection via the powersupplyof the circulating pump).
The menu for the initial operation isthen displayed.
Initialoperation menu of the pH FUN
The initial operation menu appearsautomaticallyafter a newpH FUN device is switched on for the veryfirst time.
Thismenu guidesyou through the most important settings:
•Language
Select the desired language using the arrow keys and confirmwith .
•Default
Select the default value set (standard settings) corresponding to your location using the arrowkeys .
There are 5 sets available. Use "Europe" forall countriesnot listed. Confirmwith .
•Pool volume
Enterthe volume of the swimming pool in m³ (cubicmeter)using the arrowkeys and confirm with .
The input of the pool volume servesas basis to the pH FUN forthe determination ofthe optimaldose amount.
•pH7-Calib.
Performthe pH7-Calib. (calibration of the pH measurement)to guarantee a correct and precise measurement
of the pH value in the pool water. Please proceed asdescribed in Chapter6 Performing the pH7 calib.
•To ensure that the pH FUN is able to quicklyand safelyperformitsmeasuring and controlling function fromthe very
beginning, it isrecommended that you bring the pH value of the pool waterto the optimal value(pH setpoint) of7.2
manually.
To do this, you can trigger a manual dosing (see Chapter 5 Performing a manual dosing). You can read the current
pH value on the displayof the pH FUN.
Alternatively, for largerdeviations of the pH value, you can also utilise pH-Minus/pH-PlusfromBAYROL in granular
form. Here you must absolutelyobserve the dosing instructionson the product packaging. A checkofthe pH value
ispossible using a commerciallyavailable pool tester. You can also perform this step before putting the pH FUN
into operation.
•Once the pH value is in the optimal range, you can proceed with yourpreferred method forwater disinfection.

3 Maintaining the pH FUN
ATTENTION:
Disconnect all power connections before beginning maintenance work!
3.1 Maintenance plan
Monthlymaintenance:
•Visuallyinspect all dosing linesand hoses for leakage
•Checkthe filter sieve and clean it ifnecessary. Repeat thisstep more often for strong contamination.
•Checkthe pH value using a test kit (commerciallyavailable), adjust the settings if necessary
Quarterlymaintenance:
•Visuallyinspect all dosing linesand hoses for leakage's
•Checkthe filter sieve and clean it ifnecessary
•Checkthe pH value using a test kit (commerciallyavailable), adjust the settings if necessary
•Calibrate the pH electrode with supplied buffersolution (see Chapter6 Performing the pH7 calib)
Annual maintenance:
•Visuallyinspect all dosing linesand hoses for leakage's
•Checkthe filter sieve and clean it ifnecessary
•Checkthe pH value using a test kit (commerciallyavailable), adjust the settings if necessary
•Replace and calibrate the pH electrode with supplied buffersolution (see Chapter 6 Performing the pH7 calib)
•Replace the hoses ofthe dosing pumps
3.1.1 Checking the hoses
Check all hoses for damage (e.g. kinks, tears orleakage's), contamination (e.g. leaves, hair, dust orearth) and
deposits(e.g. limescale).
Ifthere isanydoubt, always replace the affected lines. This is the onlywayto ensure a proper operation.
3.1.2 Cleaning the filter
Close the valve ofthe measurement water extractor and then the valve ofthe measurement water return. No further
water is now transported through the measurement cell and filter and the float of the flow switch sinks downwards. Now
unscrew the transparent cover ofthe filter. Use a container to catch anywaterthat runsout.
Remove the filtersieve and clean it carefully. Use clear waterto rinse it.
Nowreinsert the filter securelyin its seat and screwon the cover again. Make sure the connection is tight.
3.1.3 Dosing pump hoses
The hose ofthe dosing pump must be replaced annuallyorearlier if worn.Use the original replacement hose only. You
can obtain this at your swimming pooldealer under BAYROL Art. no.: 171 219 Replacement hose set 0.9 l/h
(identifiable bythe white hose nozzles).
Like the pH electrode, the hose ofthe dosing pump isalso a wear part and is exempted fromthe guarantee/warranty.

Instructions pH FUN V1
Page 11 of 28
3.1.4 Replacing hoses
To replace the hoses, please proceed as follows:
•Rinse the pump with fresh, lukewarmwater for about 30 minutes. To do so, place the suction lances into a pail
filled with tap waterand start a manual dosing (see Chapter 5 Performing a manual dosing).
•Subsequentlyensure that the systemis fullydisconnected fromthe powergrid. Thisprevents the pump from
switching on during the maintenance procedure.
•Remove the blue cover ofthe pump, loosen the sleeve nuts on the hose (2)and remove the suction and
pressure hose.
•Pressthe band (1)together at the recessed grips and turn the catch (4)clockwise all the way.
•Move both hose ends outward and remove the band (1) with the hose (2).
•Pullthe old hose (2) out ofthe two guides and insert the newhose.
•To mount the band (1) and hose (2), proceed in reverse order. Ensure that the hose (2)isfirmlyseated in the
guides and that the catch (4)has engaged.
•Assoon as all connectionshave been closed, you can purge the air fromthe dosing hose. To do so, connect
pH FUN with the mains and start a manual dosing.
The purging is complete when you can no longer detect airbubbleson either the suction side (canister –
pump) oron the pressure side (pump – measurement cellfor pH-Minusorinjection piece forpH-Plus dosing).

3.2 Electrode information
The electrodes must be replaced according to the maintenance plan annuallyorearlierifworn. Use original
replacement electrodesonly. These can be obtained fromyour swimming pool dealerunderBAYROL Art. no.:
185 301.
Like the dosing hose, the pH electrode is also a wearpart and is exempted fromthe guarantee/warranty.
3.2.1 Electrode wear
The following conditions, among others, indicate that the electrodesare worn:
•During the pH7 calibration procedure, the electrode takesunusuallylong to reach the value of the buffer
solution.
•The deviation of the electrode during the pH7 calibration procedure is too large, the pH7 calibration isnot
possible.
•The white KCL salt ringsin the electrode are used up or discoloured.
ATTENTION:
Electrodes wear veryquicklyif there is an electrical potentialon the pool water!

3.2.2 Electrode care
•The pH-sensitive membrane glassmust be handled with care and protected against damage.
•The innerreference solution in the glass electrode must cover the innersurface of the membrane glass. Any
air bubbles are removed bygentlyshaking the electrode vertically(like shaking a medical thermometer).
Contamination deposited on the surface ofthe membrane glass must be removed bycarefullywiping it with a moist
papertowel. Alternatively, you can use the supplied electrode cleaning solution.
3.2.3 pH7 Calibration of the electrode
For instructions on the pH7 calibration ofthe electrode, please referto 6 Performing the pH7 calib.
3.3 Decommissioning / Winter storageof thesystem
Ifthe systemis put out ofoperation forlengthyperiods, e.g. for winterstorage, certain precautionarymeasures need to
be taken. In particular, it is veryimportant that the entire systemisprotected against freezing temperatures and
humidity.
Dosing system
•Rinse the pump with fresh, lukewarmwater for about 30 minutes. To do so, you can place the suction lances
into a pailfilled with tap water and start a manual dosing (see Chapter5 Performing a manual dosing).
•Subsequentlyensure that the systemis fullydisconnected fromthe powergrid.
•Loosen the dosing hose set to prevent permanent deformation.
Measuring system
•Take the electrode out of the measurement cell and place it upright in the containers a frost-free location. The
three molar KCL solution in the containers protectsthe electrodes fromdrying out. Alternatively, the electrodes
can also be stored in buffersolution or clear tap water.
•Close the electrode drill hole of the measurement cell with the suppliedcover screw.
•Let the water drain fromthe measurement chamber and measurement lines. Connect the valvesofthe
measuring waterextractor and return.

Manual dosing
The parameter specifiesin litresthe dose amount of a manual dosing. In addition, the pH FUN shows the duration
of the manual dosing (in minutes)which results fromthe respective dose amount (see also Chapter5 Performing a
manual dosing).
Dose amount
Using the dose amount parameter, the amount ofthe pH-Minus(or pH-Plus) which the pH FUN dosesinto the pool
water can be varied.
In most cases, the standard setting "normal" delivers optimal results. Should the dosing achieved with thissetting
be generallytoo high ortoo low, a corresponding correction can take place:
Setting Description
normal Standard setting
low Doseamount isgenerallyreducedby 30% comparedtothe standard setting("normal").
high Doseamount isgenerallyincreased by50% comparedtothe standard setting ("normal").
Min.dos.rate
With increasing proximityof the pool waterpH value to the pH setpoint, the pH FUN automatically reducesthedose
rate, i.e. less and less pH-Minus (or pH-Plus) is dosed. However, this can lead to the setpoint not being reached
completely.
The minimumdosing rate of the pH FUN acts against this. It will never be fallen below aslong asthe setpoint was
not yet reached.
The standard setting should onlythen be modified when the pH value of the pool watereither doesnot reach the
desired setpoint or overshootsthe desired setpoint. (see also Chapter9.3 The pH value in the pool is not correct)
pH setpoint
The parameter specifiesthe desired pH value in the poolwater. A pH value in the rage of7.0..7.4 isrecommended
for swimming pool water.
pH alarm limits
Should the pH value of the pool waterdepart fromthe setpoint value due to a problem, the pH FUN triggers a
measurement alarm. The alarm valuesare set as range around the current setpoint e.g. 7.20 ±0.4 pH. The setpoint
in this example lies at 7.2 pH, the lower alarmlimit at 6.80 pH and the upper alarmlimit at 7.60 pH.
Acoust. alarm
Activation or deactivation ofthe acousticalarmof the pH FUN.
Language
You can switch the menu language of the pH FUN here.
Pool volume
You can enter the volume of your swimming pool in m³ (cubicmetres) here. The pH FUN automaticallyadapts the
pH-Minus(or pH-Plus)dose amount to the entered pool volume (see also Chapter7.2 Calculating the dosing rate).
Important:
The pool volume must absolutelybe entered correctlyto ensure an optimal dosing and thus a
proper control ofthe pH value bythe pH FUN.
Furthermore, there isthe possibility, where necessary, to increase the dosing amount byinput ofa
largerpool volume orto reduce the dosing amount byinput ofasmaller pool volume.

Description
pH- pH-reducing pH-Minus In themost cases, thepH value of thepool fill water liesabovethe
recommended range 7.0..7.4pH, andthe pool water generallytendstoan
increaseof the pH value. Thestandarddosing of thepH FUN istherefore

pH+ pH-
increasing pH-Plus In somecases the filling water or pool water tends to lower pH values. For this, the dosing direction of the pH FUN can be switched over to pH+ (pH-
increasing). pH-Plusmust thenbedosed.
Danger warning:
The pH regulation of the pH FUN can onlyworkcorrectlyifthe dosing direction is set correctlyand
the appropriate pool care product is used.
For the dosing direction pH-, you must use pH-Minusas pool care product; forthe dosing direction
pH+, you must use pH-Plus.
Ifthis combination is not observed, an overdosing can occur despite the comprehensive safety
mechanisms ofthe pH FUN. In extreme cases, thiscan lead to health hazard.
Dosing alarm
The pH FUN checks at regularlyspecified time intervalswhetherthe pH value ofthe pool water hassufficiently
approached the set setpoint. If this is not the case, there isprobablya problemand the pH FUN blocks the dosing.
A dosing alarmis triggered.
You can set the time interval according to which the criteria for the dosing alarmare checked. The standard setting
of 60 minutes deliversgood results in most cases.
If unnecessaryor undesired dosing alarms occur or the dosing alarmdoesnot activate as expected, the time
interval can be adapted accordingly(see Chapter 9.1 The pH FUN reports an alarm).
Danger warning:
Bysetting the time interval to 0 minutes, the dosing alarmis completelydeactivated. Doing this will
override an important safetymechanismof the pH FUN.
With deactivated dosing alarm, under certain circumstances, an overdosing can occurwhich in the
extreme case can also lead to health hazard.
We therefore expresslyadvise you against deactivating the dosing alarm. The responsibilitylies
with the operator for a deactivation ofthe alarm.
4.4 Initial operation of the pH FUN
The first time a factory-newpH FUN isswitched on, a special initial operation menu is automaticallyrun through which
will lead you step-by-step through the most important basicsettings.
The menu tree in Chapter 4.2 The pH FUN menu will provide you with an overview of the initialoperation menu.
Perform the parameter settings in the individual stepsof the initial operation menu according to the general mechanism
as described in Chapter 4.1.2 Performing a parameter setting.
Ifthe initial operation isnot run through completelyuntil it reaches the normal view, the initial operation will be started
again the next time the pH FUN isswitched on.
The execution of the initial operation is described under 2 Putting into operation
4.5 The energy-savingmode of the pH FUN
After15 minutes, the pH FUN will automaticallyswitch to an energy-saving mode. The displayillumination is switched
offin this mode. All measurement and control functionsof the pH FUN are, however, active without restriction in the
energy-saving mode. The displayillumination automaticallyswitches on and blinks for alarms.
You can exit the energy-saving mode at anytime bypressing anybutton.

5 Performing a manual dosing
Danger warning:
The dose amount orlength of time ofa manual dosing must be selected with care and expert
knowledge. An overdosing, which in the extreme case can lead to a health hazard, could be the
result.
The setting of a suitable dose amount or length oftime is the sole responsibilityofthe operator.
To ascertain the appropriate manual dose amount, please see 5.1 Calculating the manual dosing.
In certain situations, e.g. after a newfilling of the pool, it can make sense to specificallydose a larger amount of pH-
Minus (orpH-Plus)into the poolwater. The manual dosing mechanismexistsfor this purpose. During a manualdosing,
the dosing pump runs for a limited time with fulldosing rate (100%). The dose amount ofa manual dosing and the
resulting time duration can be set in the menu (0.1…4.0 litre, see Chapter4.3.3 Setting optionsin the menu setting
options in the menu).
You can start a manual dosing fromthe normal viewbyswitching the operating mode of the pH FUN to Man.-
(or Man.+). The duration in time ofthe manual dosing isthen counted down (in minutes) in the display:
7.40pH
67min_ D-100%
Aftercompletion ofthe manual dosing, the pH FUN automaticallyjumps backto the previously valid operating mode
"Auto" or "Off".
You can abort a running manual dosing at anytime byresetting the operating mode to "Auto" or "Off".
5.1 Calculating the manual dosing
The following approximation formula can be used to calculate the appropriate pH-Minusdose amount:
pH-Minus dose amount = Desired lowering of the pH value x Pool volume in m³ x 0.1 litres
Example:
In a 40m³ pool, the pH value shall be reduced from7.6 pH to 7.2 pH.
The desired lowering ofthe pH value thusamountsto 0.4
The pH-Minusdose amount calculates to 0.4 x 40 x0.1 litres= 1.6 litres.
The dosing pump of the pH FUN has a dosing rate of approx. 0.9 litres/h. Thus, the time duration for the dosing of a
specified dosing amount iscalculated as follows:
Dosing duration in min = Dose amount in litre x60 / 0.9
Forthe dose amount of1.6 litresfromthe above example, this thus results in adosing duration ofjust under
107 minutes.
5.2 Safetyfunctions for amanual dosing
With a manual dosing aswell, there are varioussafetyfunctionsactive:
•The pH FUN willblock the manual dosing for a missing flowsignal (no flowthrough the measurement cell)
•The manual dosing is blocked bya level alarm(canister empty)
•Amanual dosing in pH-reducing direction islimited bythe lower alarmlimit
•Amanual dosing in pH-increasing direction is limited bythe upper alarmlimit
In contrast, the dosing alarm is not active with a manual dosing. Fora precise description ofthe alarmand safety
functions ofthe pH FUN, see Chapter 8 Alarms and safetyfunctions.

6 Performing the pH7 calibration
Danger warning:
The regular performing ofa pH7 calibration is an important prerequisite fora correct measurement
of the pH value and thus for the correct control and dosing function ofthe pH FUN. A missing or
incorrect pH7 calibration can have asa result a pH value inthe poolwater that is too high or too
low, which in the extreme case, can lead to a health hazard.
It istherefore imperative that a pH7 calibration be performed with the initialoperation aswell as
subsequentlyat least every3 months. Anew pH7 calibration must also be performed again aftera
replacement of the pH electrode.
Moreover, the pH value in the pool water should be regularlytested using pH test strips or a
Phenol Red colour test (commerciallyavailable).
For the pH7 calibration, you will require the pH7 buffer solution, which isincluded in the scope ofsupplyofthe pHFUN.
Please followexactly the following sequence step-by-step for the pH7 calibration:
1. In the normal viewofthe pH FUN, press the button (at least 2 seconds) to call up the menu.
2. Ascreen page for the pH7-Calib. appearsimmediately:
pH7-Calib. OK_
7.09 pH
The currentlymeasured pH value is displayed in thispage, in the example 7.09 pH.
3. Stop the measurement waterflowthrough the measurement cell byclosing the appropriate shut-offvalve.
Open the container with the pH7 buffer solution.
4. Remove the plastic coverof the pH FUN measurement cell and carefullyunscrewthe pH electrode out ofthe
measurement cell. Loosen the BNC connectorof the electrode on the pH FUN device beforehand so that the
electrode cable doesnot get twisted when unscrewing the electrode. Handle the electrode byits plasticshaft
only.
5. Rinse the electrode in clean water and then dryit carefullyusing a soft cloth.
6. Now immerse the electrode in the containerwith the pH7 buffer solution. You should not swaythe electrode but
ratherimmerse it to the bottomofthe container and hold it as stillaspossible.
7. Observe the displayed pH value on the pH FUN. Afterimmersion inthe pH7 buffersolution, it will usually
change slowly. After approx. 1-2 minutesin the buffer solution, the displayshould stabilise again and only
fluctuate bya maximumof 0.01..0.02 pH.
8. When the displayed pH value forthe buffer solution has stabilised, press the button to performthe pH7
calibration.
9. The pH measured value on the pH FUN iscorrected to 7.00 pH bythe calibration. After the calibration, the
value 7.00 pH should therefore appearin the displayofthe pH FUN, wherebyslight fluctuationsin the range of
approx. 6.97...7.03 pH are normal and acceptable.
10. Now press the button again (at least 2 seconds) to return to the normal viewofthe pH FUN.
11. Remove the pH electrode fromthe buffer solution, rinse it in clean water and then dryit carefullyusing a soft
cloth.
12. Screw the electrode backinto the measurement cell again. Tighten the electrode firmlybyhand. Ensure a
secure sealing.
13. Now connect the BNC connector ofthe electrode to the pH FUN device again and attach the plastic covering of
the pH FUN measurement cell again.
14. Start the measurement water flowthrough the measurement cell again byopening the appropriate shut-off
valve.
Ifthe pH7 calibration doesnot function, please observe the information in Chapter9.5 The pH7 calibration does not
work.
