Installation Instructions

Mounting

Place the heater near an electric power socket, floor drain and the terminal for hot water utilization. There
must be a floor drainage, since there may be water flowing out of the pressure relief port of the press
relief safety valve, when the water heater is being used. Be sure the inlet and outlet of the heater are on
the bottom and are facing downward. It is forbidden to install the water heater vertically.
Warning: Be sure to install the water heater with the provided mounting hangers. The heater can be hung
up only after it is certain that the mounting hangers are solidly mounted. Serious damage and
harm may result if the heater falls off from the wall.
Installation Procedure and Cautions
• Make sure that the wall can withstand fourfold weight of a fully filled water heater.
• To locate the fixing bolts, make sure that there is a clearance of no less than 300 mm between the
right side of the heater and the wall in order to open up the plastic service cover for maintenance or
reset 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 a drill bit with a diameter of 10 mm to drill 2 holes at least 90 mm deep in the wall. The 2 holes
should be in line horizontally. The distance between the 2 holes is as shown in the below diagram.
• Use the inner hex wrench and expansion bolts to mount and fix the hangers on the wall. Refer to the
first diagram on next page.
Particular Cautions
• The nylon expansion tube must be put through the hole of the hanger first, before being inserted into
the drilled hole.
• Only special hex wrench should be used to drive the bolt into the nylon expansion tube. Once, the bolt
head has pressed against the hanger plate and made the hanger unmovable, stop further tightening
to prevent damaging the nylon tube.
