INTRODUCTION
DDPHCL2 is a compact system easy to install (wall) and maintain, which allows to monitor and control
the pH and redox potential levels in swimming pools.
The DDPHCL2 system includes a digital controller which operates accordingly with the set thresholds,
two peristaltic pumps, pH and redox electrodes with BNC connector, and down-flow probe-holder.
INSTALLATION
Warning!
Always follow the warnings and general safety information referred at the
beginning of this manual!
Install the DDPHCL2 unit away from heat sources, in a dry place protected from direct sunlight, at a
maximum ambient temperature of 40°C.
The minimum temperature shall be such as to ensure the solution to be dosed remains in a fluid state
and in no case less than that declared in the “Technical specifications” section.
The DDPHCL2 unit must be installed on a vertical wall and securely clamped. Choose a location that
allows easy calibration operations, use and maintenance.
Place the tanks of the products to be dosed below the pumps, without exceeding the maximum suction
height of the pumps (about 1.5 m).
If the system is installed below the level of the liquid to be dosed, check the condition of the injection
valves or install appropriate anti-siphon kit.
If the pump is placed above the tank and the reagent fumes could be especially aggressive, check the
tank seals.
Connect the connectors may be disconnected for packaging reasons to the respective inputs on the
bottom of the unit (see the “Functional description” section for further details).
