to ensure that the live wire and zero wire are installed correctly and grounded
reliably. Carefully check whether the capacity of electric energy meter, wire
and separate fixed socket meet the requirements of electric water heater.
Check the water pressure of tap water with a pres-sure gauge. If the water
pressure is greater than 0.8MPa, a pressure reducing valve shall be installed
on the inlet pipe.
(5) Assist users in selecting the installation position of electric water heater: avoid
the place where flammable gas leaks or the environment with strong corrosive
gas. Avoid places where strong electric and magnetic fields act directly. Avoid
direct sunlight, rain and wind. Try to avoid places prone to vibration. Try to
shorten the length between the electric water heater and the water point to
reduce the heat loss of the pipeline. There must be a floor drain with sufficient
drainage capacity near the lower part of the installation to avoid failure of
drainage. In order to facilitate future repair, maintenance and relocation, a
certain space must be reserved for the installation position of the electric water
heater. The bearing capacity of the mounting surface shall not be less than 4
times of the total mass of the electric water heater filled with water, otherwise
the user needs to install a support bracket under the electric water heater to
ensure safety.

water heater is firmly installed.
(7) Connect the safety valve, drainage hose, water mixing valve, tap water
inlet pipe and shower with the electric water heater (install a sealing ring
at the joint).
Notes:
①The safety valve (factory original identification
0.8MPa) in the accessories shall be installed
on the water inlet joint (as shown in Fig 3), and
the raw material belt shall be wound to ensure
sealing. The arrow direction shall be consistent
with the water inlet flow direction of the electric
water heater (as shown in Fig 3). The net
sealing gasket shall be installed at the cold
water inlet of the safety valve, and the drainage
hose at the pressure relief outlet of the safety
valve shall be installed to maintain a continuous
downward inclination. It shall be installed in a
frost free environment, and then extended to the
ground leakage, kept connected with the
atmosphere, and properly fixed to prevent
scalding by discharging hot water or steam. The
safety valve can prevent the tank pressure from
exceeding the rated pressure by 0.1MPa. If the
pressure in the tank is too high, the safety valve
will automatically open and drain water from its
pressure relief port to release the pressure.
②The water pipe connected to the electric
water heater must be able to withstand
pressure of 0.8MPa and temperature of
more than 100 , and the joint shall be °C
