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.
Electrical Protection
The unit is equipped with a 15 amp circuit breaker
on the back panel. See Figure 12. If the breaker
trips, its button will pop out. A tripped circuit
breaker will cause the unit to lose all power.
Press the circuit breaker button to reset.

maintained in the ISV. The ISV may be manually
refilled, if necessary.
