Flammable Gases - Lennox eCOMFORT R32 GAC 035S Installation, Operating And Maintenance Manual

FLAMMABLE GASES

As standard, the eCOMFORT range is supplied with R32 refrigerant which is a flammable gas classified A2L (slightly flammable).
A2L / A2 / A3 flammable gases are subject to more important safety regulations than gases classified A1. This section summarizes
the standard and provides specific Lennox recommendations. This section is based on the standards as well as numerical simulations
and tests related to the flammability risk carried out on these products. It provides the recommendations to be considered so that the
product is installed, used, maintained and destroyed at the end of its life cycle without putting the actors in the product life cycle at risk.
LABELS OF FLAMMABLE GAS UNIT:
The A2L logo on the nameplate indicates that the product contains refrigerant of the slightly flammable category. It is
also positioned on schraders where refrigeration components can be connected for maintenance. This label tells you that
there is a potential risk of a flammable gas leak and that this should be taken into account in the operational risk analysis.
TRANSPORT OF FLAMMABLE GAS UNIT:
Machines loaded with A2L refrigerant must comply with the ADR rules (Accord for dangerous goods by road).
Please plan the route in accordance with this class. In the case of specific air transport requiring machines not
charged with refrigerant, please contact your Lennox contact.
UN3358 transports are not allowed in Eurotunnel and tunnels of category D and E.
Containers must be fitted with stickers according to the plan below:
In the transport voucher, note: Refrigerant units.
In case the machine contains more than 12kg of refrigerant, please also note the total amount of refrigerant on the transport voucher.
In the case of maritime transport, the IMDG (International Maritime Dangerous Goods Code) is based on the same rules as the ADR.
Some specific local rules may apply (especially in Asia).
