Equipment Operation
TO AVOID POSSIBLE FLOODING OR
EQUIPMENT DAMAGE, TURN OFF THE
DOCKSIDE WATER SUPPLY
WHEN THE VESSEL IS UNATTENDED.
TYPICAL GALVANIC ISOLATOR MONI-
TOR SYSTEM
One of the most important elements in using shore power
aboard a vessel is that while it is plugged into shore power
the bonding system needs to be electrically connected to
an earth ground.
Missing this earth connection allows the bonding system
to be potentially “hot”. If this occurs, the chance for elec-
trocution to anyone in the water or boarding the boat
dramatically increases.
Your vessel utilizes a galvanic isolator. Its purpose is to
allow the separation of the bonding system from the dock
and other boats at low voltages (less than 1.4 volts) but
to keep it connected to the shore ground at high voltage
potentials. Remember, the zinc anodes installed on the
vessel protect your boat only. For this reason the name
“zinc saver” is a term sometimes used to describe the
galvanic isolator.
This type of galvanic isolator connects to your electri-
cal/bonding system for less than 20 seconds during a day.
This limits the negative effects on the ship’s bonding sys-
tem. The monitor performs various tests when connected
to shore power or activated by the push to test button or
every 6 hours after that. After it does a “self-test” then it
tests the ground wire continuity and the galvanic isolator
and shows the results on the monitor head. During the
self test the LED’s will light on the panel. It is consid-
ered a dealer serviceable item.
TO AVOID POSSIBLE BODILY INJURY DUE TO
A BUILD-UP OF HYDROGEN GAS (USUALLY
FOUND IN HOT WATER HEATERS THAT HAVE
NOT BEEN USED FOR 2 WEEKS OR MORE),
IT IS RECOMMENDED THAT THE GALLEY HOT
WATER FAUCET BE OPENED BEFORE USING
ANY EQUIPMENT CONNECTED TO THE HOT
WATER SYSTEM. THIS PROCEDURE WILL
PURGE THE SYSTEM OF ANY HYDROGEN
GAS. DO NOT SMOKE OR USE AN OPEN
FLAME NEAR THE FAUCET WHILE IT IS IN
THE OPEN POSITION.
