4.2 Guidelines for Handling Refrigerants
4.2.1

Glossary of Terms

Refrigerant: Refrigerant fluid (Exclusively. R134a ).
A/C System: Air-conditioning system in the vehicle.
Flushing: Action of rinsing the A/C system and/or components.
Unit / service station: Texa Konfort K605E, K610E, K610E BUS, K650E, K670E.
Internal vessel: Refrigerant storage tank.
Phase: Execution of an individual function (Ex. Vacuum).
Cycle: Execution of more phases.
Recovery: The recovery of refrigerant in any condition and its storage in a container
outside the A/C system, without necessarily undergoing analysis or treatment of any
kind.
Recycling: A reduction of the contaminating substances in used refrigerants through
oil separation, the recovery of incondensable and their single or multiple passages
through elements that enable a reduction in humidity, acidity and particles.
TXV: Thermostatic Expansion Valve
Vacuum: Phase in which incondensable and moisture are evacuated from an A/C
system solely by means of a vacuum pump.
4.2.2

Precautions for refrigerant storage

The refrigerant to be removed from a system must be handled carefully in order to prevent or
minimise the possibilities of different refrigerants mixing.
The Konfort A/C service stations are specifically designed for the treatment of the R134a.
The tank used for storing refrigerants must be assigned to specific refrigerants to avoid
different refrigerants mixing.
The tank used must be free of oil and other contaminants and must be clearly marked in order
to identify the refrigerants they contain.
4.2.3

Conditions of the refrigerant and the system

A system's history and age can be important factors in deciding whether a system's refrigerant
is to be recycled.
Installation and maintenance procedures carried out during the system's service life have a
considerable effect on the quality of the refrigerant.
Systems that have not been cleaned or properly evacuated may have high levels of
contamination in the refrigerant and in the oil. If the system's history is unknown, the
refrigerant removed must be at least recycled before being re-introduced into the system.
When users are unsure of the level of the refrigerant's contamination, preliminary checks can
be performed using special kits for measuring acidity and humidity.
4.2.4

Recycling Capacity

The unit's recycling filter system should be replaced regularly in order to maintain the
efficiency of the recycling unit.
