INTRODUCTION
The Tebas-Economic EFka265 is a compact system easy to install (wall) and maintain, which allows to monitor and control
the pH and redox potential levels in pools. The EFka265 system includes a digital controller which operates accordingly with
the set thresholds, two peristaltic pumps 4 l/h, pH and redox electrodes with BNC connector, and probe-holders.
INSTALLATION
Warning! Always follow the warnings and general safety information referred at the beginning of this
manual!
Install the EFka265 unit away from heat sources, in a dry place protected from direct sunlight, at a max. 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 EFka265 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).
