1.5.2 Earthing of the pH value measurement
Measurement water extractor and return are each provided with an earthing. These earthings ensure that any
interfering electrical potentials that may possibly be present in the pool water are safely diverted.
Note:
The supplied earthing of the measurement water extractor and return MUST be installed. This
earthing MUST be 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) of the vacuum pump.
Connect the other side with the injection piece at the measurement cell (only BAYROL pH-Minus; BAYROL pH-Plus is
directly dosed 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 connections are tight and securely fastened.
1.7
Dosing of pH-Plus (increase of the pH value)
Danger warning:
Should pH-Plus be utilised for increasing the pH value instead of pH-Minus for reducing the pH
value, the pH-Plus may not be feed into the measurement cell, it must be fed directly into the
circulating line.
You will require the following accessories (available at your BAYROL dealer):
•
100 509 PE hose (length depending on the installation situation)
•
171 207 Injection piece 0.5 bar (1 piece)
•
112 283 PVDF Plug screw (1 piece)
•
112 174 Saddle clamp 50mm ½“
or
112 148 Saddle clamp 63mm 1“ + 112 151 Adapter 1“-1/2“
or
112 149 Saddle clamp 75mm 1“ + 112 151 Adapter 1“-1/2“
(dependent on the pipe diameter of the circulation system in each case)
Installation:
•
If possible, fit the saddle clamp for the injection piece for pH-Plus directly in front of the return of the water to the
pool, but after all built-in parts (e.g. heat exchanger) into the circulation system.
•
Screw in the injection piece 171 207 into the threads of the saddle clamp. Ensure a secure sealing.
•
Remove the upper white PVDF elbow on the measurement chamber of the pH FUN and instead screw in the PVDF
plug screw 112 283 in the measurement chamber. Ensure a secure sealing.
•
Connect the PE hose 100 509 to the pressure side of the pH dosing pump of the pH FUN. Run this hose in the
most direct path as possible to the injection piece. Do not run the hose over sharp edges and do not run it directly
past heat-conducting pipes. Ensure a secure and tight connection at pH dosing pump and injection piece.
•
Connect the suction line which is located on the suction lance with the suction input (left connection) of the dosing
pump.
Ensure that all connections are tight and securely fastened.
