3.8 Internal Tank Manual Refill
When the MAC2000 remains turned ON during the day, the unit
automatically refills the internal tank with refrigerant from the
external source tank. An operator, however, can manually add
refrigerant as follows:
1. If not already done, plug the MAC2000 into a properly grounded
AC outlet; set the Power switch to ON; then wait until the unit
completes its self diagnostics. The screen will display “Select
mode” when ready.
2. Press the Next menu function key to display Menu 2. Then press
the Tank refill function key to begin the refill process.
Note: If the tank is already filled with 12 lbs or more of refrigerant,
then the message “Tank already full” appears.
3. Press the Start key to continue. The screen will then display “The
internal tank is now being refilled.” When the internal tank is
filled, the screen displays “Tank refill complete.”
4. Press the Reset key to return to the Main menu.
