MAC2000 Maintenance
To replace the external source tank:
1. Close tank valve; remove yellow hose from tank valve; release tank
strap; then remove tank from side of unit.
2. Place a new source tank on the shelf and secure it with the tank
strap. The tank strap must be set up to supply liquid – this
usually means the tank is inverted.
3. Reconnect the yellow hose to the tank fitting; then open the tank
valve.
4. The unit’s automatic tank refill function will add refrigerant to the
internal storage vessel as the unit is used. A technician may fill it
immediately, however, by pressing the Next menu function key to
display Menu 2, and then pressing the Tank refill function key to
immediately begin filling the internal storage tank.
4.3 Replacing the Printer Paper
1. Open the printer cover by first squeezing together the cover’s two
plastic latches, and then pulling the cover forward.
2. Remove the old paper-roll core.
3. Insert the new paper roll so that it unrolls over-the-top. Then pull
out several inches of paper and position the paper so that it rests
against the paper cutter.
4. Close the printer cover.
5. Press and hold the feed button to ensure that the paper feeds
properly; then tear off the excess paper.
