MAC2000 Operation
3 Operation
3.1 MAC2000 Operational Overview
The MAC2000 is an EPA-approved, ETL-listed, single-pass recycling
system. During the recovery operation, refrigerant is removed from
the vehicle and passed through an oil separator and filter drier before
entering the storage tank.
The MAC2000’s refrigerant weighing system is extremely accurate. It
has sophisticated error correction capability that minimizes incorrect
readings caused by bumps or vibration. Even with this protection,
however, the MAC2000 should be placed on level ground and out of
the way of foot traffic. Do not touch or move the unit while it is
operating!
To ensure that the displayed reading of recovered refrigerant is
accurate, the unit will perform a low side clearing routine, if
necessary, when the power is turned on. If refrigerant is sensed in the
accumulator, the screen will display “
Clearing System ”. This
indicates refrigerant in the accumulator is being transferred to the
storage tank.
At any time during system operation, pressing the
Weight Convert
key can change the weight units. The available units are pounds only,
pounds & ounces, or kilograms.
Power Up
– When power is applied, the unit performs a self-
diagnostics. When these tests are complete, the display shows “ Select
mode .”
Main Data Display

Section 1.5 on Page 7.) Shows the date, time, ambient temperature,
RH%, AC line voltage, low- and high-side pressures, and the amount
of refrigerant available for charging. Use the function keys (F1 – F5)
