Circuit Protection
The appliance has 4 locations for circuit protection. The Main Circuit Breaker Panel, the Pump Set
Circuit Breaker Panel, the Pump Control Panel and the Rear Cabin Electrical Panel.
The Main Circuit Breaker Panel is on the near side of the appliance above the vehicle batteries. It
houses the circuit breakers for the Radio Memory, Cabin, Pump, Primer, Battery Charger and the
NS and OS Hose Reels. The Radio Memory circuit breaker is connected directly to the batteries
and not through the Battery Isolator. This circuit requires continuous voltage to maintain memory
circuits.

Access to the Pump Set Circuit Breaker Panel is from the near side Deck Platform. There are
circuit breakers here for the Pump Batteries, Alternator, Pump Panel and the Battery Charger.
Also, there are circuit breakers for the Volume Pump and Charge Equalizer circuit.

Pump, Pump Ignition and the Air Compressor. Inside the Pump Control Panel, there are circuit
breakers for CAFS -12V, Reducer 1, Reducer 2 and Auxiliary Reverse.
