Plumbing connection
Caution:
Apply proper sealing to the pipe joints to prevent leakage. At the same time,
the relief valve may not be tightened excessively to avoid damage.

While installing a control box on the Wall, if the grooves
or clips are installed on the Wall, lay the control wire into
the grooves or through the clips directly, and then fix the
control box on a dead plate preinstalled on the wall. In case
that the gland is embedded in the wall, firstly remove four
screws of the control box, open the box, and take out the
control wire from the Control box; plug off the wire from
the PCB, and then pass the control wire through the
gland(pay attention to not damage the ten-pin wire); plug
the ten-pin plug on the PCB, then fix the PCB into the
backcover, close the front cover, screw down the screws,
and finally secure the whole control box on the dead plate
preinstalled on the wall.
ControI Box Connection
The power cord and plug has been provided for the water heater. Users only needs to insert the
plug into the corresponding electrical socket.
Power connection
Caution:
Ensure that the socket is grounded reliably. Use an independent high-quality
socket, its rated current should not be less than 5.5A(CEWHR-PE6-1200)
/13.1A(CEWHR-PE6-3000) and ensure reliable contact with the plug.
After all the pipes are connected, first open the discharge valve of the water heater, then the
feed valve. Then fill the water heater with water
, exhaust the air till water stream flows
uniformly out of the hot water outlet. This indicates that the water heater has been filled up.
Please close the hot water discharge valve and check all connections for any leakage. If leakage
occurs, empty the inner tank, repair the leaked connection and then refill the water heater with
water.For your convenience, please don’t close the feeding valve while filling the water
.

Relief Valve
Connect the valve provided with this unit to the inlet
of the (inlet pipe has a blue cap). The arrow points
to the direction of water flow (to the water heater).
The relief valve must be connected to the discharge
pipe. The hot water pipe is connected to the water
outlet (outlet pipe has a red cap). If the water pressure
of the inlet pipe approaches to or exceeds the relief
limit (0.8 MPa) of the multi-functional relief valve,
please install a reducing valve on the water inlet pipe
away from the water heater. Refer to Fig. 5 for pipe
connection. PPR pipes should be used for connection
between the tapping pipe in users house and the water heater.
