CAUTION
!
To reduce the risk of minor injury to persons, malfunction, or damage to the product or
property when using this product, follow basic precautions, including the following:
INSTALLATION
• Install the product on a firm and level floor.
• Do not install the water heater in a place where leakage of the tank or connections will result in
damage to the area adjacent to it or to lower floors of the structure. Where such areas cannot
be avoided, it is recommended that a suitable drain pan, adequately drained, be installed
under the water heater.
• Install the water heater in a place where the noise from the water heater will not inconvenience
the neighbors.
• Install the drain hose properly for the smooth drainage of water condensation.
• Be sure to check if there is a refrigerant leak after installing or repairing the water heater.
•To reduce the risk of excessive pressures and temperatures in this water heater, install
temperature and pressure protective equipment required by local codes and no less than a
combination temperature and pressure relief valve certified by a nationally recognized testing
laboratory that maintains periodic inspection of production of listed equipment or materials, as
meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water
Supply Systems, ANSI Z21.22. This valve must be marked with a maximum set pressure not to
exceed the marked maximum working pressure of the water heater. Install the valve into an
opening provided and marked for this purpose in the water heater, and orient it or provide
tubing so that any discharge from the valve exits only within 6 inches above, or at any distance
below, the structural floor, and does not contact any live electrical part. The discharge opening
must not be blocked or reduced in size under any circumstances.
OPERATION
• Do not place objects on top of the appliance.
• Do not use this appliance if any part have been under water. Immediately contact an
Authorized Service Center for replace flooded water heater. Do not attempt to repair the unit. It
must be replaced.
• Turn off the power and water supply to water heater and drain water heater if the appliance is
to be left for an extended period of time, such as during vacations.
• Hydrogen gas is produced in a hot water system served by this heater that has not been used
for a long period of time (2 weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE.
To reduce the risk of injury under these conditions, it is recommended that the hot water faucet
be opened for several minutes at the kitchen sink before using any electrical appliance
connected to the hot water system. When hydrogen is present, there will probably be an
unusual sound such as air escaping through the pipe as the water begins to flow. There should
be no smoking or open flame near the faucet at the time it is open.
