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.
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 profes-
sional 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.
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).
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.
11. If any parts and components of this electric water heater are damaged,
please contact with the professional maintenance personnel for repair,
and use the special spare parts and components provided by our
company.
