forthis purpose andsuitable equipment.
To prev ent t he risk of ex plosion due to spray ing of c oolant and oil, the relevant circuit shall be drained and at zero
pressure before any disassembly or unbrazing of the refrigerating parts takes place.
There is a res idual ris k of press ure build-up by degassing the oil or by heating the exchangers after the circuit has been
drained. Zero pressure shall be maintained by venting the drain connection to the atmosphere on the low pressure side.
The brazing shall be carried out by a qualif ied brazier. The brazing shall comply with standard NF EN1044 (minimum 30%
silv er).
Replacing components:

- Whatever the supply conf iguration is, respect a minimal duct’s length of 2m before any elbow or any duct’s section change.
COMMISSIONING:
- It must only be carried out by trained ref rigeration engineers.
- Don’t forget to open the insulationv alve on t h e l i q u i d l i n e b ef o r e st art ing t he unit
