Installing the measurement water circuit
•
Place the measurement water extractor and return as shown in the installation plans (see Chapter 2.8). To do
this, use saddle clamps into which you then screw in the measurement water extractor and measurement
water return.
•
Connect the measurement water extractor and prefilter at the measurement chamber of the pH FUN using a
piece of measurement water hose.
•
Connect the measurement water return and output of the measurement chamber of the pH FUN using a
section of measurement water hose.
Electrical connection
The system has been designed and constructed according to the applicable regulations. It was carefully inspected
before leaving the factory and left the factory in a perfectly safe condition.
The equipment can only be operated safely if all of the instructions contained in this manual are followed. The
equipment should be installed by a licensed electrician.
The supply voltage for the device may not exceed 240V/50 Hz. The allowable operating temperature range is from 0 to
50
O
C, and the allowable humidity level equals 0-90%.
Ensure that all plug-in connections are protected against water, as is standard practice for electrical connections.
Danger warning:
For safety reasons, the pH FUN should be connected in such a way so that it is only supplied with
current when the circulating pump is running. Together with the float switch in the measurement
cell, this ensures the maximum amount of operational safety. It is thus impossible for the dosing
pump to dose pH-Minus (pH-Plus) into standing water.
