DANGER: RISK OF EXPLOSION
It is perceived that using a Vacuum Pump, with an A2L system, has a lower risk than carrying
out a refrigerant recovery. This assumption is based on the fact that a system shouldn't have any
refrigerant in it, because it is either new, and it is yet to be charged, or the gas has been removed,
using a suitable Refrigerant Recovery Unit (XTR-Altima A2L, XTR-Pro DV A2L or Ultra A2L). Care
should still be taken however, as trace quantities of mildly flammable refrigerant, may remain in
the system (e.g. refrigerant off-gassing from the oil).
The A2L CC Vacuum Pumps are designed to safely evacuate systems which utilise A2L
refrigerants. However, the operating environment, must be FREE of high concentrations
of hazardous or flammable gas, prior to use. Therefore please ensure that an appropriate
combustible gas leak detector, is used to ensure the working environment is safe, prior to starting
any work.
The A2L CC Vacuum Pump should only be plugged in to a power outlet, outside of the 3m
exclusion area.
During the evacuation process, a combustible gas leak detector should be used to ensure that
none of the refrigerant is leaking into the local environment. If it is, safely stop the process and
ensure adequate ventilation to the area to dissipate the gas.
A dry powder or CO fire extinguisher must be available at the service location and in close
2
proximity to the unit which is being worked on.
NOT TO BE USED WITH A3 HYDROCARBON REFRIGERANTS:
The A2L CC Vacuum Pumps are designed for use with systems which utilise mildly flammable
A2L refrigerants. They are not designed for use with A3 hydrocarbon refrigerants.
