3.
The wall in which the electric water heater is installed shall be able to bear
the weight equalling twice the weight of the heater fully filled with water
without distortion or cracks. Otherwise, other strengthening measures
should be adopted.
The one-way safety valve attached to the machine must be installed to the
4.
cold water inlet of this machine (see Fig.6).
5. For the first use (or the first use after maintenance or cleaning), the heater
can not be switched on until it has been (fully) filled with water. When filling
with water, at least one of the outlet valves at the outlet of the heater must
be opened to release the air. This valve can be closed after the heater has
been (fully) filled with water.
6.
During the 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 leaking, please contact 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.
Hot water
The drainage pipe connected to the pressure release hole must be kept
7.
sloping downwards.
Since the water temperature inside the heater can reach up to 75℃, the hot
8.
water must not be exposed to people when it is initially used. Adjust the
water to a reasonable tempeature to avoid scalding..
9.
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).
