INTRODUCTION

This manual is intended to simplify routine and extraordinary
maintenance on the new air-conditioning recharging units Konfort 700R
series.
The first chapter of this manual will aim to compare the features of the
two refrigerants R134a and R1234yf in relation to their use in air-
conditioning systems and, therefore, in the new Konfort 700R series
equipments.
Since any type of assistance operation is not possible without an
excellent knowledge of the equipment (in particular, of the components
involved during its operating cycle), in the next chapter plenty space will
be given to the description of each component involved in the cycle,
firstly starting with a description of the overall operation, then gradually
giving further details to the description.
In particular, the way in which Konfort 780R BiGas equipments are able
to do the switch between the two types of refrigerant will be analyzed.
The third chapter will describe the main functions of the menu of the
Konfort 700R series equipments.
In the fourth chapter, then, the features of the Service menu of the
equipments will be carefully described. Particular attention will be given
to the section which allows to check the functioning of the sensors and
actuators of the Konfort unit. Furthermore, a detailed description of the
new calibration procedures of the equipment's sensors will be provided.
The fifth chapter will provide a brief description of the main ordinary
maintenance operations which will have to be periodically performed on
the equipment.
The sixth chapter explains the procedures that are necessary to follow to
perform the software updates required during the normal service and
assistance operations on the equipment.
Finally, the seventh chapter will review in detail the techniques of
diagnosis and resolution of problems you might encounter in the work of
maintaining of Konfort equipments, produced by TEXA S.p.A. The goal is
that of providing an easy-to-use trouble shooting, where each problem is
separately dealt, leading the reader to its correct solution.
