Refrigerant And System Conditions; Recycling Capacity; In General - TEXA KONFORT 700R Technical Manual

• The refrigerant removed from the A/C system must be handled with care, in order
to prevent the refrigerants from mixing or in any case reduce the risk of this
happening.
• The cylinders used for refrigerant storing must be specific to each refrigerant in
order to prevent the refrigerants from mixing.
• The cylinders must be perfectly clean and clearly labelled in order to identify the
refrigerant contained within.

2.7.2 Refrigerant and System Conditions

The installment procedures and the maintenance carried out during the
operating life of the A/C system substantially affect the quality of the refrigerant.
The understanding of these factors is essential in order to decide whether or
not the refrigerant from a system should be recycled.
The systems that have not been properly maintained (not cleaned, not emptied
correctly, etc.) can have high contamination levels, both in the refrigerant and
in the oil.
If the history of the system is not known, the refrigerant recovered must at least
be recycled before it is reused.
When the contamination level is not known, you may carry out some preliminary
checks with the kit specifically for acidity and humidity measurements.

2.7.3 Recycling Capacity

The filtering systems of the device must be replaced regularly in order to
guarantee device efficiency.
The recycling must always be carried out, even when tests do not show that
they are required.

2.7.4 In General

Before carrying out the refrigerant refilling phase, the A/C system must be
emptied and cleaned (a vacuum operation must be carried out).
Carry out all the procedures as described in this manual in order to guarantee
that the A/C system is free of contamination.
Carry out the scheduled/regular maintenance on the device as required,
especially after it has been used with a highly contaminated refrigerant: it is
essential that the contamination from one operation is not passed on to the
following one.
