MOUNTING THE UNIT
INSTALLATION
7. Mounting the Unit
!
NOTICE:
Unit must be installed in a vertical position with the water fittings pointing upward.
WARNING:
Do not install unit where it would routinely be splashed with water. Electric shock may result.
CAUTION:
Hot water outlet pipes leaving unit can be hot to the touch. Insulation must be used for hot water pipes below a height of 36˝ (.91 m) due to burn risk to children.
!
NOTICE:
This unit should not be installed in a location where it may be exposed to freezing temperatures (less than 36 °F (2 °C). If the unit may be subject to freezing temperatures, all water must be drained from the unit. Failure to comply with this instruction voids all warranties.
The unit should be located in an area where water leakage from the unit or connections will not result in damage to the area adjacent to the unit. If such a location cannot be avoided it is recommended that a drain pan be installed under the unit.
1 Drill two ¼� holes in the wall where the water heater will be mounted.
2 Install plastic wall anchors.
3 Fasten wall mounting bracket to the wall.
4 Hook water heater to the mounting bracket.
5 Pull downwards on the water heater to properly seat it on the bracket.
8. Plumbing Connections
!
IMPORTANT:
If water pipes are made of copper or bronze, use dielectric connections to prevent heater corrosion.
Failure to provide dielectric insulation may result in premature tank or nipple failure and may void your warranty.
!
IMPORTANT:
In order to avoid water coming in contact with the male pipe threads, ensure that all thread pitches are sealed properly. It is especially important that the first thread pitches be fully sealed to ensure no leakage will occur after the water connections have been securely made. Failure to properly seal pipe thread pitches may allow water to come in contact with the male threads and create corrosion.
!
NOTICE:
Hard water or water with a high mineral count may damage the unit. Damage to the unit caused by scale or a high mineral count is not covered under the warranty.
CAUTION:
To reduce the risk of excessive temperature and pressure in the water heater, a temperature/pressure
(T&P) relief valve has been installed.
CAUTION:
Always fill the unit’s tank with water before plugging the water heater’s cord into an electrical outlet. Failure to do so will result in permanent damage to the water heater.
!
NOTICE:
When a water heater is installed in a closed water supply system, such as one having a back-flow preventer in the cold- water supply, means shall be provided to control thermal expansion. Contact the water supplier or local plumbing inspector for information regarding the control of this situation.
Connect the cold water pipe to the cold water connection on the unit (blue). Connect the hot water pipe to the hot water connection on the unit (red).
Ensure that the water heater is installed in a level position.
Install a shut-off on the cold water side of the water heater. This is for emergency shut-off. It must be kept open when the water heater is operating.
When using copper piping, solder a piece of tubing to a threaded fitting (union) before screwing the adapter to the tank.
BRAIDED FLEX HOSE CONNECTORS ARE ALSO RECOMMENDED.
DO NOT APPLY HEAT DIRECTLY TO INLET OR OUTLET CONNECTIONS.
A certified T&P valve is mounted to the water heater by the manufacturer with the outlet oriented to the right. If this position needs to be changed, leakage may occur, especially if it will be screwed counter-clockwise, and the T&P valve may need to be resealed.
After all plumbing work has been completed, the T&P valve needs to be checked for proper tightness.
During heating, the water volume and water pressure increases in the tank. It is possible for water to leak from the safety valve, this is normal.
It is recommended to install a check valve on the cold water inlet supply line to the unit so that air pockets can be purged through the T&P valve.
