Save the setting by holding in button E for 2 seconds directly after finished confirmed LED indication until LED 1 and 7 blink
rapidly.
6. To check which setting the unit has: turn off, wait approx. 3 sec., turn on power to the unit ‒ LED 1 to 7 blinks during the start
sequence with ensuing blinking indication as per point 5.

To change the dosing setting for acid, repeat from step 1. When the start sequence is done, the set mode is confirmed with
a blinking indication:

Adjustment screws
Adjustment screws (H) and Measurement water tap (N) are cleaned as necessary so they do not seize due to being coated.
1. Switch off dosing (on/off button E) - LED blinks.
2. Cut off the flow with the ball valves (L1 and L2).
3. Screw out the adjustment screw, rinse it and wipe it off.
4. Lubricate the O-ring and plug thread with a little silicone grease. Reinstall them. Open the ball valves (L1 and L2).
5. Activate dosing (on/off button E) - LED is lit with a steady glow.
Winter storage
Upon the risk of freezing, the modules and prefilter should be emptied from water, bottom plugs removed, electrodes uninstalled
and stored frost-free in their delivery container filled with tap water.
Filter
Check the filter regularly and clean as necessary. Replace the cartridge when necessary.
1. Switch off dosing (on/off button E) - LED blinks.
2. Cut off the flow of water by closing the ball valves (L1 and L2).
3.
Unscrew the filter can where the cartridge sits.
4. Replace the filter or rinse it clean with regular water. A soft brush can be used if necessary.
5.
Reinstall filter. Open the ball valves (L1 and L2).
6.
Activate dosing (on/off button E) - LED is lit with a steady glow.
13. Care
•
Upon back flushing of the pool's sand filter - first close the shut-off valves (L1 and L2) on the prefilter to and from MiniMaster.
•
Check flow with pressed button (F) - adjust to the right flow with adjustment screw (H) on the start module.
•
Reference measurement of chlorine and pH should be performed 1-2 times per month with digital photometric measurement
equipment and with subsequent calibration. Take measurement water from measurement water outlet on the prefilter.
Upon a deviation from calibrated value - clean the electrodes and calibrate afterwards.
•
The plug threads and O-rings should be lubricated at least once per year with silicone grease with PTFE (non-petroleum-
based grease).
•
Check hoses, connections and chemical levels regularly.
Electrodes
Should be cleaned regularly (see instruction MA60-06: Electrodes, handling and care), at least once a month for a fresh water
pool. For a salt water pool, contact ÅF for information on handling and care of MiniMaster in salt water.
1. Switch off dosing (on/off button E) - LED blinks.
2. Cut off the flow of water by closing the ball valves (L1 and L2).
3. Lift up the lock arm (M) and lower the modules forward, see picture 3.
4. Disconnect the electrode's BNC connector (see picture 5) from the control unit.
5. Unscrew the electrode and lift it upwards.
6. Clean and rinse off the electrode. Reinstall the electrode and BNC connector. Open the ball valves (L1 and L2).
7. Activate dosing (on/off button E) - LED is lit with a steady glow.
Handling of chemicals
Liquid chlorine and liquid acid are strong chemicals with alkali and acidic properties.
These MAY NOT be mixed with each other as this can cause strong chemical reactions.
The different chemical containers shall be placed well separated from each other and stand in its own
reclamation container.
When handling these chemicals, protective equipment shall always be used, such as protective gloves,
apron and protective glasses.
