7. WARNINGS
Please note: When using electrical appliances, basic safety precautions must be followed to reduce
the risk of fi re, electrical shock, or injury.
This Whale® Heater must be installed by a qualifi ed marine electrician.
Hydrogen Gas
•
Hydrogen Gas can be produced in a hot water system that has not been used for a long period of time
(generally 2 weeks or more). Hydrogen gas is extremely fl ammable.
•
To reduce the risk of injury under these conditions, prior to using electrical appliances, the user must ensure
that the hot water faucets in the galley are opened for several minutes until there is a smooth water fl ow. If
hydrogen is present, there will be an unusual sound similar to air escaping through the pipe as the water
begins to fl ow.
•
Run the faucet for several minutes until there is a smooth water fl ow to release all the gas.
•
WARNING - Do not smoke or have any open fl ame near the faucet when checking for hydrogen.
Galvanic Corrosion
•
To help prevent possible damage due to electrolysis, installing a galvanic isolator is recommended.
•
Galvanic corrosion is not covered under warranty.
Corrosion
•
Corrosion may occur in your Water Heater due to high current or in areas of hard water with a higher
concentration of dissolved salts.
•
This Water Heater is therefore supplied with a sacrifi cial anode to prevent rapid corrosion.
•
Anode rods preserve the life of a Water Heater by corroding themselves instead of the heater.
•
These anode rods are easy to replace and must be checked for corrosion every 6 months. Please see
Maintenance (Section 10) for more information.
•
Please note - Zinc anodes do not prevent corrosion, magnesium anodes are recommended.
