INTRODUCTION
The
Tebas-Economic EFka300
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 system includes a digital controller which operates accordingly with the set thresholds, two dosing pumps with a flow
rate of 10 l/h and input for level sensor, 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
Tebas-Economic EFka300
away from heat sources, in a dry place protected from direct sunlight, at a maximum
ambient temperature of 45°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 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).
