MiniMaster
5. Once the start sequence is complete, the mode set is confirmed using the following flashing indicators:
‒ LED no. 2, 4 and 5 flashing = alkali dosing activated.
Save the setting by keeping button E pressed for 2 seconds immediately after LED indication confirmation has completed
until LEDs 1 and 5 start to flash quickly.
6. To check the unit's setting: shut off, wait around 3 seconds, turn power back on to the unit - LEDs 1-7 flash during the start
sequence, with the flashing indications as described in point 5.
7. In order to change dosing settings for acid, repeat the process from step 1. Once the start sequence is complete, the mode
set is confirmed using the following flashing indicators:
‒ LED no. 2, 4 and 6 flashing = acid dosing activated.
13. Maintenance
• When rinsing the pool sand filter – close the shut-off valves (L1 and L2) on the pre-filter running to and from the MiniMaster.
• Check the flow by pressing button (F) – adjust to the correct flow using set screw (H) on the start module.
• Reference measurement of chlorine and pH levels must be carried out once or twice a month using digital photometric
equipment and calibrating accordingly. Take measurement water from the measurement water outlet on the pre-filter.
In the event of a deviation from the calibrated value – clean the electrodes and re-calibrate.
• The threads and O-rings of the plugs should be lubricated at least once a year using silicon grease with PTFE (non-petroleum
based grease).
• Check hoses, connections and chemical levels on a regular basis.
Electrodes
Should be cleaned on a regular basis (see instruction MA60-06: Electrodes, use and maintenance), at least once a month in the
case of freshwater pools, and twice a week in the case of salt water pools.
1. Shut off dosing (on/off button E).
2. Shut off the water flow by closing the ball valves (L1 and L2).
3. Lift the locking brace (M) and fold the modules forward, see Figure 3.
4. Remove the electrode's BNC contact (see Figure 5) from the control unit.
5. Unscrew the electrode and lift it up out of the unit.
6. Clean, rinse and refit it.
Filter
Check the filter on a regular basis and clean if necessary. Replace the filter cartridge as a when required.
1. Shut off dosing (on/off button E).
2. Shut off the water flow by closing the ball valves (L1 and L2).
3. Unscrew the filter housing in which the filter cartridge sits.
4. Replace or rinse the filter using normal tap water. A soft brush may be used if necessary.
Adjuster screws
Adjuster screw (H) and Measurement water tap (N) must be cleaned if necessary so that they do not seize due to scale build-up.
1. Shut off dosing (on/off button E).
2. Shut off the flow using the ball valves (L1 and L2).
3. Unscrew the adjuster screw, rinse and dry off.
4. Lubricate the O-ring and the thread of the plug using a little silicon grease.
Winter storage
• Where there is a risk of freezing, the modules and the pre-filter must be drained of water, bottom plugs and electrodes
removed and stored in a frost-free location (standing in water).
