A red light on top of the unit flashes whenever a process is complete or when the unit needs attention from the technician. The MAC2000 is ETL listed to UL standards and meets SAE specifications for recycled refrigerant. 1.1 Glossary of Terms A/C Air conditioner or air conditioning A/C System The vehicle’s air conditioning system Unit The MAC2000 itself Screen LCD Display Contaminated Refrigerant that has been mixed with some other type of refrigerant. 1.2 General Operating Guidelines • The MAC2000 monitors the AC line voltage and disables itself if the voltage drops below 100 VAC or rises above 135 VAC. An error message will be displayed on screen when the line voltage is out of tolerance. The unit must be turned OFF and then back ON to reset the voltage monitoring circuitry. Extension cords must be a minimum of 14 AWG and kept as short as possible. Common causes for electrical problems include: - Long extension cords - Faulty, overloaded electrical circuits - Drop lights - Improper ground or improper polarity • The screen shows options and gives instructions for most service and maintenance tasks. Read the on-screen prompts and follow their instructions. • The MAC2000 prompts a technician to check the system oil drain bottle on the side of the unit for recovered oil. Any system oil that is lost is automatically drained during recovery. A technician must measure and record the lost amount of oil in order to know how much new oil to add during charging. Refer to the A/C system manufacturer’s service manuals for oil specifications. Dispose of used oil properly. • In general, it is best to leave the MAC2000 turned ON throughout the workday. This allows the unit time to purge itself of air and refill the internal storage tank. Turn the unit OFF at the end of the day. 1.3 Component Location and Description MAC2000 Control Panel High Side Gauge – Shows the pressure in the high side of the vehicle’s A/C system.
