4. Drill holes for the remaining four screws.

5. Hang the unit again by the first screw, and then

insert and tighten the remaining four screws.

6. Take waterproofing measures so that water does

not enter the building from screws mounting the
device.

• Make sure the unit is installed securely so that it will

not fall or move due to vibrations or earthquakes.

Tapping Screw

Location of Screw Hole

1. Drill a single screw hole, making sure to hit a stud.

2. Insert and tighten the screw and hang the  unit by

the upper wall mounting bracket.

3. Determine the positions for the remaining four screws

(two for the top bracket and two for the bottom), and
remove the unit.

• The weight of the device will be applied to the wall. If the strength of the wall is not suffi-

cient, reinforcement must be done to prevent the transfer of vibration.

• Do not drop or apply unnecessary force to the device when installing. Internal parts may

be damaged and may become highly dangerous.

• Install the unit on a vertical wall and ensure that it is level.

• If this water heater is being installed at an elevation of

2,000 ft. (610m) or higher, disconnect the connector
labeled "High Elevation Disconnect" as illustrated on
the right. This connector is located inside the unit.

• Disconnect power to the water heater before discon-

necting this connector.  Failure to perform this step will
result in a flashing light on the unit or a "73" code dis-
played on the optional remote controller and a cease
in operation.  If this occurs, disconnect, then reconnect
power to the water heater to reset the system.
