Installation

Mounting
1. Make necessary plumbing with reference to the installation diagram on the right page.
2. Connect the safety valve in the water inlet [blue]. It must be installed at the side of the inlet pipe. It
has been factory set at 0.8 MPa and is not adjustable. The discharge tube of this valve must face
downward and the discharged water must be piped up to or within 15cm above a suitable drain.
Under any circumstances, the drain line cannot be blocked and must be open to atmosphere.
Attention: The direction of arrow points to the water heater that indicates the direction of the water
flow current.
3. Connect the hot water pipe to the outlet [red].
Attention: Make sure a suitable sealing tape is used for all connections to prevent leakage. Meanwhile,
the safety valve must not be screwed too tight to prevent damage.
Plumbing
1. Make sure that the wall can withstand at least twice the weight of water heater when completely filled
with water.
2. Before locating the position for installation, make sure that there is a clearance of no less than 300
mm between the front of the heater and the wall. This allows easy opening of the decorative front
panel for maintenance or to reset the thermal cutout when necessary.
3. Use a drill bit with diameter of 10mm to drill 4 holes at least 90mm deep in the wall. The four holes
should be aligned horizontally and vertically. The horizontal distance between the 2 holes should be
120mm and the vertical distance should be 57mm, as shown in the above diagram.
4. Insert the expansion anchors into the holes. Place the wall bracket over the expansion anchors and
tighten the screws on the bracket.
5. Hang the water heater using the hanger hooks on the wall, through the 4 holes on its mounting
bracket. Move the water heater downward to ensure that the holes are pressed against the root of the
hanger hooks and ensure the water heater is fixed steadily.
