COMMISSIONING NOTES

Note No.1

If your Cal Yacht is supplied with a 110V AC shore-power system, it will have a control panel 

with a main breaker (30 amp) and separate (15 amp) breaker switches for the outlets and 

water heater . In addition, there are both audible (buzzer) and visual (yellow light on panel) 

reverse-polarity indicators . With all switches off, attach the power cable to the power inlet on 

the boat . Next, connect the power cable to the dockside outlet . It is recommended that any 

appliances used on board be wired with three-wire grounded plug .

WARNING: IF THE POLARITY INDICATORS LIGHT AND/OR SOUND, DISCONNECT THE 

CORD IMMEDIATELY . THIS INDICATES A REVERSE POLARITY SITUATION WHICH IS 

DANGEROUS . SEVERE INJURY OR DEATH MAY RESULT . DIAGNOSE AND CORRECT THE 

PROBLEM BEFORE PROCEEDING .

Note No.2

If your Cal Yacht is equipped with a water heater, it will be installed to operate off both the 

engine cooling system and the 110V AC electric system . Before switching the 110V system on, 

be sure the water-heater tank is filled . Open the valve in the inlet water line, and be sure the 

check valve is installed with the arrow pointed toward the water heater . Operate the pres-

sure-water system until you get a steady stream through the hot-water faucets .

WARNING: FAILURE TO FILL THE WATER HEATER BEFORE SWITCHING ON THE 110V 

CIRCUIT WILL RESULT IN DAMAGE TO THE HEATING ELEMENT .
