Special notices
In order to guarantee the correct and safe application of the water heater, our company here notifies
customers that it is necessary to contact the professional service providers specified by Haier for home
service. In case of incorrect installation of the water heater, our company undertakes no responsibility.
z Ensure the water supply of the machine before powering it on; otherwise, it may cause faults in the machine
components. Ensure that air switch meets the national standard and is reliably grounded; it is forbidden to use
the water heater in case of unreliable grounding.
z When the electric water heater is seriously eroded by water, it can be cleaned up for reuse only if it is
inspected and accepted by our company’s technical personnel.
z Don’t place inflammable articles such as gasoline nearby the water heater; otherwise, accidents such as fire
hazards may take place.
Installation method
z It must be installed by professional installation personnel of our company’s after sales service department or
specified installation personnel.
z The water heater should be hung vertically on the wall and installed closely against the wall; it is forbidden
to be installed inversely or horizontally to ensure the sensitivity of the water flow switch.
Waterway installation:
z Before installation of the water heater, first carry out waterway installation, the installation method as
follows:
z First, determine the installation position of the water heater.
According to the installation dimensional drawing, drill three holes
with aФ4mm and the depth of 30mm in the wall; plug the plastic
expanding tubes into the holes A, B, and C (see the back view in
P3); then, screw bolts into the plastic expanding tubes in the upper
and right holes (don’t screw them in completely to facilitate
machine hanging); and fix these bolts firmly. Then, lift the water
heater and hang the back shell of the machine on the bolts; screw
another bolt into the plastic expanding pipe C and screw it firm. At
last, assemble the front shell of the machine and fix them with
bolts.
z There are the words “inlet” and “outlet” printed at the bottom of the water heater. First, install the filter
screen at the intake pipe; and then, connect the intake pipe with the outflow pipe and the shower nozzle; the
joints must be cushioned with seal rings to prevent water leakage; the installation refers to the drawing
above.
z Note: The hot water pipe should not be too long so as to avoid heat loss.
z When installing the water heater, there should be certain space set aside to facilitate future repair &
maintenance .
Circuit installation
z After the completion of waterway installation, test whether water can flow freely in the pipes; carry out
circuit installation if there is no water leakage.
Select proper air switch and power line according to the power of the water heater; the power line should be
connected with the water heater through the air switch. Be aware of the difference among the live wires
(brown/red/black), the zero line (blue) and the ground wire (yellowish green).

Matters needing attention for installation·Components introduction
Matters needing attention for installation
z The electric water heater should be installed indoors where the ambient temperature is above 0℃; pipelines
should be arranged together. It is not suitable for the hot water outlets far away from the water terminals. If
the distance is over 8m, heat preservation treatment should be carried out on the pipeline to reduce heat loss.
z The electric water heater should be installed in places where it is easy for use and maintain and there are
buried pipes. In case of water leakage in the water tank or water pipes, no damage will be caused to the
nearby or lower story facilities. Besides, don’t install the water heater in places where water sprays directly
and it is easily frozen.
z Due to its high power, before installation of the water heater, carefully inspect whether the electric
instruments, the wire diameter of power supply and fuse meet with the requirements of the rated current and
voltage of the water heater.
z Intake and outflow pipes must not be connected inversely (hot on the left and cold on the right).
z To ensure safety, air switch which measures up to the standard of the state should be used in the water heater,
and be grounded reliably. As the required current is very high, the power supply of the incoming line should
be connected directly to the air switch. Do not use the power plug.
z Check whether the live wire and the zero line are connected inversely with an electroprobe. Power-on the
water heater for heating until it is confirmed that the water tanks are fully filled with water, there is no water
leakage in the various joints and the power supply meets the requirements.
z Safety warning: in order to prevent the occurrence of accidents, accessories such as hosepipes and shower
nozzles provided by our company must be installed and must not be replaced or substituted; if the pipe
fittings are damaged, inform our company’s repair & maintenance department to repair them and replace
them with accessories provided by our company. If accidents occur due to disobeying the matters and
attentions above, our company assumes no responsibility for the direct or indirect loss caused by the
accidents.

Usage·Matters needing attention for usage
Usage
z After the installation of the water heater for the first use, first carry out a water test; switch on power supply
until water flows continuously out of the shower nozzle or other water outlets.
z After switching on the power supply, regulate the water flow switch to get the appropriate water flow; then,
the machine will start up automatically; turn the power button to determine the gearshift required.
z After electrifying and heating for about 2s, hot water will flow out of the outlet (the practical outflow time
depends on the pipe length).
Temperature set
As to DSF80MB I (E), DSF65MB I (E) and DSF80MB II (E), after switching on the power supply and
turning on water flow switch to get the appropriate water flow, the screen will display the current water
temperature. For example, Fig. A shows the current water temperatures of DSF80MB I (E) and DSF65MB I
(E); Fig. B shows one of working interfaces of DSF80MB II (E). After switching on the power supply,
regulate the outflow temperature through the power regulating button and water flow regulating button.
Regulate the power according to the signs on the power button; in case of constant outflow, turn up the power
for heating, the outflow temperature rises correspondingly; on the contrary, the outflow temperature declines.
If stopping use of the water heater for long time, please shut off the air switch of the water heater. If required,
the customer can regulate the outflow temperature by regulating the water flow or power.
