maintenance. And the facilities will not be damaged nearby or downstairs even
leakage of tank or conduit has been taken place.
The electric water heater should be installed indoors with ambient temperature
above 0°C.
Power supply
To ensure safety, please use a separate socket which is
reliably grounded and complies with the national standard.
Never use the water heater when it is not reliably grounded.
Check with an electro-probe to ensure that the live wire and

Cold water supply
It is important to ensure that the cold water main is capable
of supplying the increased demand. A minimum pressure of
approximately 0.05MPa (0.5 bar ) is required for
satisfactory operation.
NOTE: THE MAINS WATER SUPPLY MUST NOT EXCEED 0.75MPa
(7.5 BAR).
Installing Dimension
A certain space shall be reserved during installation of the
water heater with no less than 250 mm at the top and
bottom, no less than 700 mm at the forward and both sides,
so as to be convenient to the future maintenance. If water
heater is embedded in gusset plate during installation, the
right gusset plate shall be movable so that the plastic cover
can be removed for convenient maintenance.
Water Piping
The pipe layout shall be centralized. The distance between
the outlet and use spot of hot water shall not be too far
away. If it is more than 8 m, insulation measures shall be
taken for hot water pipe to reduce heat losses.
Never connect the inlet and outlet wrong. The safety valve shall be installed in the
specified location which can’t change it without authority; the discharge hole shall be
kept connecting with the atmosphere and never blocked.
The water heater which is used for the first time must be filled up with water before you
switch on the current!

2.2 Installation Method
 The water heater must be installed by the installation professionals from our after-sale
service department or its designated personnel.
 The wall-hung type installation shall be adopted for the water heater.
 As shown in Fig.1, drill four holes of 12 mm in diameter and 65 mm in depth in the wall
by a percussion drill, insert and fix expansion hooks and expansion bolts into the
corresponding holes, and then raise the water heater, put the wall-mount rack on the
hooks and bolts; finally mount the accessories, such as relief valve, mixing valve,
nozzle and hose with reference of section 2.3. It is noted that PTFE tape shall be used
for sealing, so as to prevent from leakage.
 For convenient installation and disassembly of the water heater, it is recommended that
G1/2 loose joint shall be respectively mounted at the proper position of inlet and outlet
of water heater. Confirm the location where need to be supplied hot water, and connect
the outlet, inlet and tap-water pipe of the water heater to such reserved locations. Hot
water pipe shall not be kept too long so as to avoid heat loss.
 The hands could be left only after the wall-hung rack is surely hang on the hooks, so as
to prevent from falling the water heater, which may cause personal injury or property
damage.
