Installation method
The electric water heater shall be installed by professional installation
personnel in accordance with the requirements of the national standard of code
for installation of electric water heater.
1. Installation Preparation
(1) Professional installation personnel shall prepare installation tools and
necessary measuring qualified inspection instruments.
(2) Check whether the electric water heater is in good condition and whether
the attached documents and accessories are complete.
(3) Carefully read the operation manual to understand the function, operation
method, installation requirements and installation method of the electric
water heater to be installed.
(4) To check the power supply of users, 230V~/50Hz power supply must be
used.The electrical connection of electric water heater shall generally adopt
special branch circuit, and its capacity shall be greater than 1.5 times of
the maximum current value of electric water heater. The position of the
separate fixed socket shall be placed in a safe position where there is no
danger of electric shock and its water cannot be splashed. The separate
fixed socket used by the electric water heater shall be inspected by visual
inspection and special measuring devices (phase meter, test pen, grounding
resistance meter, etc.) 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.
