1. Product description
MiniMaster is an electronic unit for checking and controlling the pH and/or chlorine level in a pool.
The pH value is measured with a pH electrode and the chlorine level is measured with a free chlorine electrode.
MiniMaster can be linked with dosing equipment for acid/alkali (pH) and chlorine.
The package contains: 1 control unit, 2 4m PE hoses, prefilter and hose connections.
Electrode kit supplied separately: contains electrode(s), cleanser and for the pH model also buffer solution pH 7.3.

3. General info
MiniMaster measures and continuously indicates the pool water’s pH reading and chlorine content.
Upon deviant readings, the control unit gives signals to external dosage equipment that applies doses.
To maintain balanced water quality, it is important to follow our recommended readings as per below.
pH readings outside the recommended readings will provide misleading chlorine readings at MiniMaster.
If the pool water was previously dosed with organic chlorine containing cyanuric acid (such as in tablet/puck form), this may
cause an incorrect chlorine measurement (for action; see section 8 point 8).
We recommend use of a photometric test instrument for reference measurement and calibration.
MiniMaster must be mounted on a wall or similar and must sit straight. The installation space for MiniMaster is recommended
to be indoor or under a roof, and to be easily accessible to be able to easily take readings, perform service, take water samples
and clean the prefilter.
Recommended readings regarding water quality
Chlorine content:
0.5-1.5 mg/l (ppm)
pH reading:
7.2–7.6
Alkalinity:
60-120 mg/l (ppm)
Chloride (salt) content:
max 5000 mg/l (ppm) = 0.5%
Calcium hardness:
100-300 mg/l (ppm)
Cyanuric acid:
max 5 mg/l (ppm)
For more details on pool chemistry and care, refer to the pool user’s guide on our website http://www.pahlen.com/users-guide/
4. Safety
Dosage of chlorine, acid or the like shall be done AFTER all other equipment to minimise the corrosion risk.
Dose points in the circulation system for liquid acid and chlorine shall be as far apart as possible, although a minimum of
500 mm and
chlorine dosing shall always be placed last
