WARNINGS
This manual is dedicated to the technical personnel responsible of the installation, management and
maintenance of the plants. The manufacturer assumes no responsibility for damages or malfunctions occurring
after intervention by non-authorized personnel, or not compliant with the prescribed instructions.
Before performing any maintenance or repair action, ensure that the system is electrically and hydraulically
insulated.
Dispose of waste material and consumables accordingly with local regulations.
GENERAL SAFETY TIPS
WARNING! Before performing any operation on the pump, unplug the pump and discharge the liquid from the
pump head and tubes. Never operate on working pump!
During maintenance and repair of parts that normally become in contact with chemicals, always wear all
prescribed personal protections (gloves, clothes, glasses, etc.).
The pump has to be handled by qualified personnel only. Always use original spare parts for maintenance.
Failure to follow instructions can cause damage to the equipment and, in extreme cases, to people.
The manufacturer can modify the instrument or the technical manual without advanced notice.
Warranty
The device is warranted for a period of 12 months from the delivery date.
Warranty is not valid if all instructions of installation, maintenance and use, are not strictly followed by the user. Local
regulations and applicable standards have also to be followed.
In particular, the warranties regarding the operational safety and reliability of dosing pumps will be recognized only if the
following conditions are fulfilled:
oThe installation, wiring, adjustment, maintenance and repairs performed only by qualified personnel
oThe dosing pump was used according to instructions provided in this manual
oOnly original spare parts have been used for repairs
From the guarantee are excluded all consumables (tubing, seals, etc.). Mechanical damage is not covered under warranty.

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).
