1. Find minimum room size acceptable based on EN 378 = refrigerant charge (kg) / (lower flammability
limit X 0.2) in the tables below
2. Check whether your cellar size is bigger
– If it is, that’s great you can move on to the next part if not
try the following:-
a. Reducing your pipe run
b. Use 2 smaller systems instead of 1 big system.
Products for spare parts, please ensure the use of official Marstair spares. Any spare parts taken from other
companies, Marstair will not be responsible in case of any damage and will be out of warranty.
Refrigerant must be recovered by a certificated technician before the plant is dismantled. Modern refrigerant recovery
machines should be able to remove well over 95% of the refrigerant in an old system.
All recovered refrigerants can either be:
a) Sent for destruction by incineration at a licenced waste facility
b) Sent to a specialist plant that can re-process the old refrigerant into a gas with properties identical to virgin
refrigerant, to create “reclaimed refrigerant”
c) Given a basic cleaning p
rocess, to create “recycled refrigerant”
Given the refrigerant supply shortage that will be created by the phase down process, it is worth trying to send the old
refrigerant for reclamation as it may have a good residual value. If the old refrigerant is too contaminated it cannot be
reclaimed and must be sent for destruction. It is important not to mix different gases in the same recovery cylinder
–
as this would render them unsuitable for reclamation.
Reclaimed refrigerant can be used in any refrigeration equipment. Recycled refrigerant must always be used with care
as it may be contaminated or of unknown composition.
