Set the power socket of the water heater
in a dry position away from water. Never
insert or pull the power plug with wet
hands to avoid electric shock, injury or
other accidents.
Before initial use after installation, please
first fully fill water and then switch on the
power. If it is powered when the tank is

During winter in cold areas, if the heater
is not used for a long period, please
unscrew the blow down nut to drain the
water to avoid damage caused by icing.
Please remember to fill it with water
before turning on the power when it is
used again. The hot water tube may be
relatively long due to the installation
location of the water heater. Please drain
the cold water before use each time to
avoid getting cold water.
Do not use electrical products with
damaged power cords or loose power
sockets and plugs. Otherwise electric

Technical parameters
Using method
The rated temperature of the water heater is 75 . The indicator lamps will illuminate in
heating state. When it reaches the rated temperature, the power will be turned off and
the indicator lamps will go out.
Large amount of water will come out from the drain hose of the relief valve if the
pressure of the tap water is higher than 0.7MPa. This is caused by overly high water
pressure. Please call the after-sales service center. Water or vapor will come from the
drain hose of the relief valve if the temperature of water inside the inner tank exceeds
. It is reducing temperature by relieving pressure as the temperature is too high.
Please call the after-sales service center in this case. Please keep away from the drain
hose during use to avoid scalding.

Cleaning and maintenance
To clean the outside: Disconnect the power supply before cleaning the water heater.
Wipe it lightly with a piece of wet cloth dipped in a little neutral detergent other than
gasoline or other solutions. Then, wipe it with a piece of dry cloth and keep the shell dry.
Do not clean it with detergent containing abrasives (e.g. toothpaste), acid, chemical
solvents (e.g. alcohol) or polish.
To clean the inside: To keep the water heater working efficiently, the heating elements
and the inner tank should be cleaned once every three years. Take care not to damage
the protection coating outside the heating element and inside the inner tank. The
magnesium anode rod should be replaced periodically according to local water quality
and the using habits.
To clean the inner tank: Blowdown procedure: disconnect the power supply, turn off the
inlet valve and turn on the relief valve to relieve pressure. When no water comes from it,
turn off all the water outlet valves. Remove the drain hose of the relief valve together
with the double nipple. Then, unscrew the blowdown nut. Connect the drain hose with
double nipple on the blowdown port (put the other end of the drain hose in the sewer
inlet). Turn on any one of the water outlets to conduct blowdown. Clean water coming
out of the drain hose indicates the dirt in the inner tank has been totally discharged.
Install all the components in their original places. Note: the water inlet valve should be
turned on several times to rinse the dirt at the bottom of the inner tank during blowdown.
Note:Please deal with simple issues by referring to the attached
before calling a
service person.
Statement:Maintenance or repair work can only be performed by qualified service persons.
Improper methods may cause serious accidents or property damage. Make sure
to unplug the water heater before you intend to open the water heater or repair it.
