MiniMaster
1. Product description
MiniMaster is an electronic unit that monitors and controls the pH value and/or chlorine levels in a swimming pool. The pH value
is measured using a pH electrode, whilst chlorine levels are measured using a free chlorine electrode.
MiniMaster can be connected to a dosing module for acid or alkali (pH) and chlorine.
The pack contains: 1 x control unit, 5 m PE hose, 1.5 m PVC hose, pre-filter and hose couplings.
The electrode kit is supplied separately, containing electrode(s), cleaning agent and, in the case of the pH model, also pH 7.3
buffer solution.

3. General information
MiniMaster continuously measures and indicates the pH value and chlorine content of pool water.
Where values to not conform to specified limits, the control unit issues signals to an external dosing module that doses the water.
In order to maintain a balanced water quality, it is important that you adhere to the recommended value detailed below. pH values
outside the recommended limits will provide misleading chlorine values in the MiniMaster.
If the pool water has previously been dosed with organic chlorine (e.g. in tablet/disc form), this may produce inaccurate chlorine
measurements (for measures to correct this, see section 8, paragraph 7).
We recommend you use a photometric test instrument to obtain a reference measurement.
MiniMaster must be installed against a wall or similar, and must sit straight. It is recommended that MiniMaster is installed
indoors or under cover, and is easily accessible in order to enable easy ready of values, allow servicing to be carried out, take
water samples and clean the pre-filter.
Recommended values in respect of water quality
Chlorine content:
0.5-1.0 mg/l (ppm)
pH value:
7.2-7.6
Alkalinity:
60-120 mg/l (ppm)
Chloride (salt) content: max 10 g/l (1%)
Calcium hardness:
100-300 mg/l (ppm)
Cyanuric acid:
max 5 ppm

4. Safety
The MiniMaster supply voltage must be interlocked in parallel over the connection to the pool circulation pump. This is to ensure
reliable supply and to protect against accidental dosing when the circulation pump is not in operation.
Dosing of chlorine, acid or similar substances shall be done after all other equipment in order to minimise the risk of corrosion.
Dosing points in the liquid acid and chlorine circulation system shall be positioned as far from each other as possible, but at least
500 mm, and chlorine dosing must always be positioned last, see Figure 4.
