Since the water temperature inside the heater can reach up to 75
℃
, the hot
water must not be exposed to people when it is initially used. Adjust the
water to a reasonable tempeature to avoid scalding..
In order to drain off the water inside the inner container, it can be drained
off from the exit port (Twist the thread screw of the exit port), and it can also
be drained off from the one-way safety valve (Twist the thread screw off the
one-way safety valve, and lift the drain handle upwards).
If the flexible power supply cord is damaged, the special supply cord
provided by the manufacturer must be used, and replaced by the profes-
sional maintenance personnel.
If any parts or components of this electric water heater are damaged,
please contact the professional maintenance personnel for repair, and use

Check the power supply plug and socket frequently to make sure that they
have good, reliable contact and are well grounded without overheating.
If the heater is not going to be used for a long time, especially in the regions
with low temperatures (lower than 0
℃
), in order to prevent the heater being
damaged due to the freezing of water in the inner container, the water
inside the heater shall be drained away (refer to Item 9, Cautions of this
manual for the method to drain away the water inside the inner container).
The recommended water hardness for an optimum working performance of
the water heater should not exceed 120 mg/l of CaCo3 (Calcium Carbon-
ate). In case of exceeding this quantity, it is recommended to use alterna-
tive decalcifying systems (You can check your local water hardness in the
Water Board of you local Town Hall.) Should there be any failures due to
the deposits originated by the water quality, will not be covered by the guar-
antee.
