Installation of electrodes

The electrodes kit is delivered separately and contains what is needed for each MiniMaster type.
Any kit contains one or two electrodes, operation and maintenance instructions, measuring cylinder and electrode cleaning agent.
pH units also contain pH 7.3 buffer solution.
Check that you have obtained the right electrode kit on delivery:
Type
Free chlorine
pH
pH - free chlorine
pH - Redox
Carefully read information provided with the electrodes to be installed, see "Electrodes, operation and maintenance" (MA60-06).
Every electrode is supplied with a container filled with storage solution that can be saved for electrode future storage, e.g. if
Mini Master shuts down for a long period.
Electrodes are highly sensitive measuring instruments and should be handled accordingly. Never touch electrode ends with
hands/fingers. They must be kept in a liquid medium (electrodes storage solution, pool water or tap water). A longer dry period
can destroy electrode or shorten its service life.
An electrode must be kept free of oil, grease and other contaminants.
An electrode must not be subject to pressure.
1. Rinse electrodes and their ends with a clean tap water. Wipe electrode ends with a clean, damp, lint-free cloth.
2. Install it into the corresponding marked module (Free chlorine, Redox, pH).
3. Connect the electrode BNC connector to the corresponding labeled controller.

Preparation

Make sure that the pool water values are within the recommended limits (see section 3 "Water chemistry"). Use photometric
measuring instruments and adjust the value manually, if necessary, with the required chemicals. Note that reactions can take
different amounts of time in the pool, depending on the volume and turn-around times.

Start-up

1. Turn power to Mini Master on (controllers will perform a start-up sequence for
Belysning
a few seconds).
2. Open all taps for water measuring.
3. Press Flow (J) button on any of the control units.
(This needs to be done on the left controller when there are two of them
4. Adjust the flow with flow screw (L) until LED No. 1 has 4 lights. Make sure the
flow goes through modules (displayed in window (M)) and flows freely through
hoses.
5. If the drain hose is mounted onto the pump suction side (or B Fig. 2 ),
ball valve L2 (Fig. 7) should open by 25-50 % in order to avoid vacuum in
electrode modules.
Check and if necessary adjust the flow again.
6. Any of the two controller LEDs will either blink or glow steadily:
Blinking LED = standby mode (only measuring).
Steady light = automatic mode (measuring and dosing).
Press (H) button to switch to standby (only for measuring) on both controllers.
7. Let water flow through the modules for at least 30 minutes to achieve the
electrodes stabilization and eliminate air.
