Installation Instruction

Installation:

Locate the heater near electric power socket, floor drain and point of water use.  Be sure the inlet

and outlet of the heater are on the bottom and facing downward.  Don't permit to install it vertically!

Warning: Be sure to install the water heater with the provided mounting brackets.  The heater can be
hung up only after the mounting brackets are solidly mounted and double check.  Serious damage
and harm can result if the heater falls off from the wall.

Make sure that the wall can withstand double weight of fully filled water heater.
To locate the fixing bolts, make sure that there is a clearance of no less than 300mm between the right
side of the heater and the wall in order to facilitate opening up the plastic service cover for maintenance
or resetting the high limit when necessary.  In case the water heater is embedded in the ceiling, the
right side ceiling of the heater should be removable so as to remove the plastic service cover for
maintenance when necessary.
Use 10mm drill to drill 2 holes of at least 90mm depth in wall.  The 2 holes should be in line horizontally.
See Figure III for distance specification.
