Installing the remote controller
For convenience of operation, you may install the remote 
controller holder/bracket on the wall near the water heater 
(a bracket may be used). 
Installing the bracket for remote controller:
• The remote controller must be installed at a place 
where it does not get in contact with water.
• Drill two holes on the wall by using an electric impact 
drill with 6mm bit.
• The holes must be horizontal and space between two 
holes is 28mm (Fig. 7).
• Fix the bracket on the wall by expansion tubes and 
screws attached. 
• Place the remote controller with battery into the 
bracket.
Installing the remote controller battery:
• Rotate counter clockwise by a coin and remove the battery cover at the back of the 
remote controller. 
• Load the CR2025 battery (accessory) into the controller. 
Note: “+” up. 
• Cover the battery cover and rotate it clockwise by a coin (Fig. 8).
