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.
