Installation Instructions (Cont)
Position of chemistry Control System
A wall space of at least 700mm high by 400mm wide is required. Mount the controller with the
TOP of the assembly no more than 1700mm from ground level.
The system is mounted on a backboard and the water sample inlet is on the left hand side with the
return on the right hand side of the measuring cell when viewed from the front.
The control unit and chemical storage areas should be easily accessible to the operator. Protective
clothing should be available for use and warning signs present.
The points of injection and storage (both labelled correctly) (flocculent, pH correction and chlorine
donor) should be not less than 2 metres apart and should be easily accessible. The injection points
should be situated after the control system sample line take off, not above head height, but above
the top of the day tanks to avoid siphoning and not placed above any equipment that would be
damaged by any leakage. The injection points should be post filter, heater and UV system. The
dosing lines should be as short as possible and run in protective sleeving. Dosing pump foot valve
assemblies should be supported in rigid pipe held clear of agitators and 4cm clear of the day tank
bottom. If CO2 is used to correct the pH and the plant room is confined or below ground level,
then a CO2 leakage detection sensor must be provided. A water supply with appropriate siphon
protection (mains, not pool water!) should be provided for making up chemical solutions. If UV
systems are used to treat the water, larger dosing pumps may be required.
