Installation Instructions (Cont.)
Position of chemistry Control System
A wall space of at least 600mm high by 450mm wide is required. Mount the controller with the
TOP of the assembly no more than 1700mm from ground level.
The system and measuring cell are mounted on a backboard. The water sample inlet is on the left
hand side ( as seen facing it ) with the return outlet on the right hand side of the unit.
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 injection points and storage
(pH correction and chlorine donor) should not be less than 2 meters 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. They should not be
placed above any equipment that could be damaged by any leakage. The dosing lines should be as
short as possible and run in protective sleeving marked with red and white tape for acid and
yellow and black for chlorine. Dosing pump foot valve assemblies should be supported in a 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 a confined space or below ground level, then a CO2 leakage detection
sensor must be provided. A water supply (mains, not pool water!) should be provided for making
up chemical solutions.
