WARNING 
It is extremely important to follow these instructions! Improper setup will result in potential inaccuracies when operating the unit.
1.Un-box the MAC2000.
2.Open the accessory box that contains the rear and side tray mats, the high- and low-side service hoses, the snap-shot transmitter, and one spare printer paper roll.
3.Drop the mats into the side and rear storage trays.
4.Attach the blue low-side service hose to the service-hose fitting with the blue label, and attach the red high-side service hose to the red service fitting.
5.Attach the snap-shot transmitter to its magnetic storage plate.
6.Install an external source tank of R-134a refrigerant on the lower shelf of the unit, below the handle. The external source tank should be inverted so liquid refrigerant is supplied to the internal tank. The MAC2000 can handle 30 lb (14kg) or 50 lb (23kg) commercial tanks. Secure the tank to the unit by placing the strap around the tank and tightening it. WARNING: Failure to secure the source tank properly could result in injury!
