MAC2000 Initial Set-Up
2.2 Checking Vehicles for Possible
Contaminated Systems
Before every recovery, the MAC2000 automatically samples the
refrigerant in the vehicle’s A/C system. If the system fails the purity
level required, the unit tests a second time. In the event the system
fails a second time, the unit prompts that the hoses be disconnected
from the vehicle. Follow the on-screen prompts in order to clean out
the MAC2000.
Note: The MAC2000 must be disconnected from the vehicle before
starting the cleaning process. It is illegal to knowingly vent or allow
refrigerant to vent to the atmosphere. This illegal venting will occur if
the unit is left attached to the vehicle.
Please refer to your shop’s policy for dealing with contaminated
refrigerant.
2.3 External Source Tank Testing
The MAC2000 features an exclusive source tank refrigerant
identification process that checks the source refrigerant before it is
added to the unit’s internal tank. This testing is automatic and does
not require any action by the technician. This feature prevents
contaminated refrigerant from entering the MAC2000, thus rendering
it inoperable.
