► Cautions
Power cord
One-way safety valve
Sewerage
exit(30L)
Hot water
Cold water
(Fig. 5)
Thread screw
Drain handle
Pressure release hole
(Fig.6)
3.The wall in which the electric water
heater is installed shall be able to bear
the load more than two times of the
heater filled fully with water without
distortion and cracks. Otherwise, other
strengthening measures shall be
adopted.
4.The one-way safety valve attached
with the machine must be installed at
the cold water inlet of this machine (see
Fig.5).
5.For the use of the first time (or the
first use after maintenance or clean),
the heater can not be switched on until
it has been filled fully with water. When
filling the water, at least one of the
outlet valves at the outlet of the heater
must be opened to exhaust the air. This
valve can be closed after the heater
has been filled fully with water.
8.Since the water temperature inside the heater can reach up to 75℃, the hot
water must not be exposed to human bodies when it is initially used. Adjust the
water temperature to a proper point to avoid scald.
9.In order to drain away the water inside the inner container, it can be drained
away from the exit port (Twist the thread screw of the exit port off), and it also
can be drained away from the one-way safety valve (Twist the thread screw
off the one-way safety valve, and lift the drain handle upwards). (See Fig. 6)
10.If the flexible power supply cord is damaged, the special supply cord provided
by the manufacturer must be selected, and replaced by the professional
maintenance personnel.
1. The supply socket must be earthed reliably. The rated current of the socket
shall not be lower than 10A. The socket and plug shall be kept dry to prevent
electrical leakage. Inspect frequently whether the plugs contact well with the
socket. Inspect method is as follows: insert the power supply plug into socket,
after using for half an hour, shut down the unit and pull the plug out, and inspect
the plug whether it scalds hand. If it scalds (over 50℃).
2.For the places or the wall where the water may splash, the installation height of
the socket shall not be lower than 1.8m.
6.During heating, there may be drops of water dripping from the pressure release
hole of the one-way safety valve. This is a normal phenomenon. If there is a
large amount of water leaked, please contact with the professional maintenance
personnel for repair. This pressure release hole shall, under no circumstances,
be blocked; otherwise, the heater may be damaged, even resulting in safety
accidents.
7.The drainage pipe connected to the pressure release hole must be kept sloping
downwards.
