General Maintenance
1. On a regular basis, wipe off the unit using a clean
cloth to remove grease and dirt.
2. Periodically check internal components for leaks; over
time, fittings can loosen as the unit is moved. Open
the door panel, and trace lines using a leak detector.
Check connections on the back of the unit. Tighten
any loose fittings or connections you may find.
