Cleaning and Maintenance
Installation must be made by installers of or designated by our company after-service department.
The water heater shall be wall-mounted.
Before installation, make sure water heater rear wires are fit firmly. Determine an installation
location. Make four holes Ø12mm, 65mm deep in the wall. Insert and fix expansion hooks and
expansion bolts in corresponding wall holes. Lift the water heater. Insert wall rack onto the
hooks and bolts. Fit flat washers, rear wires, spring washers and nuts in turn onto the bolts.
Tighten the nuts and check them firm. Install accessories such as safety valve, drain hose as
shown in Fig. 2. Use sealing compound to prevent water leakage.
To facilitate installation and removal, it is suggested a G 1/2" movable nut is fitted at
appropriate locations on inlet and outlet pipes respectively. Find water supply location.
Connect inlet pipe, outlet pipe and city water pipe respectively to the use point.
Note: To avoid heat dissipation, hot water pipe shall not be too long.
For easy future maintenance and repair, adequate space must be reserved during installation.

Operation Instructions
During installation, adequate space must be reserved for future maintenance and repair. If
the water heater is installed within decoration boards, the right board shall be removable to
facilitate removing the plastic cover during maintenance.
City water inlet pressure shall not be less than 0.05 MPa.
Electric water heater shall be installed indoors with ambient temperature above 0
o
C. The
pipes shall be collectively laid. Hot water outlet shall not be too far from use points. In case
farer than 8 m, hot water pipe shall have a thermal insulation to minimize heat loss.
The mounting wall shall be firm and reliable to support twice the weight of water heater
full of water. Non-load bearing walls or air brick walls must have corresponding protective
measures like additional support, wall-through screws or back boards.
Electric water heater shall be located in a place easy for use, maintenance and with a floor
drainer. In case the tank or pipes leak, nearby or lower facilities shall not be damaged. The
installation location shall avoid being above toilet bowl, bathtub, washbasin or doorframe,
where will cause a suppressed or unsafe feeling to users.
Power socket for water heater shall be in a dry place free of water splash. (splash-proof box is preferred)
Do not confuse inlet and outlet water pipes. Safety valve shall be installed at designated
position with no random modification.
The safety valve should be connected to the cold water inlet
pipe. Please check carefully if the direction is correct after
installation. The correct direction of installation is that the
arrowhead on the safety valve should point to the water heater.
If your water heater is not installed in a bathroom with sewage
drain, please connect the drain hose to the safety valve. Connect
one end of the hose to the safety valve vent and the other end
to the sewage drain. The hose can be cut short or extended as
necessary. The hose shall be installed as inclined downward.
The water may drip from the discharge pipe of the pressure
relied device and that this pipe must be left open to the
atmosphere. Check safety valve once a month as follow: move
the small handle of safety valve, if there's water flowing out,
safety valve is normal; if there's no water flow, please contact
local after-sales service station.
The pressure relief device is to be operated regularly to
remove lime deposits and to verify that it is not blocked.

Attentions in Operation
1
To avoid causing machine troubles, do not connect power before tank is full of water.
2
Adjust a suitable temperature before use, for water temperature above 50
o
C may burn your skin.
3
This product is closed water heater, which can supply hot water through pipe connection to
several points like bathroom (bathtub, washbasin, showerhead) and kitchen.
4
Heating adjustment can be made flexibly all year round adapting to climate changes. After long-term out-
of-use, you can close city water pipe valve, screw one end of the drain hose onto the safety valve pressure
relief vent, open safety valve handle, and adjust the mixing valve of water heater to the max. hot water po-
sition (at the same time, unscrew the nozzle hose from mixing valve and please be ware of the hot water
burns) to drain the tank. To avoid injury, before next use, it is suggested to first open hot water valve be-
fore switching on the water heater. In this case, no smoke or fire is permitted near the open valve. Please
carefully check and confirm all parts are in good condition, and the tank is full before use.

Setting Environment
The product adopts Haier "Safe Care" patented technology. In normal installation, even in severe
case that ground wire is live due to wrong connection, the product "Safe Care" technology can
filter and efficiently ensure your safety. However, whenever your feel a sensory current, please pull
out the power plug and notify local after-service men in time. Do not dismantle by yourself.
The tubes and pipes fitted on the product are inseparable parts of the "Safe Care" technology,
and shall not be removed by yourself. Otherwise, Haier shall not be liable for any damages or
injuries caused due to resulted potential risks.
For the first use after installation, due to there's no water within the tank, first the city water
inlet valve and mixing valve must be opened. Close the mixing valve when water flows out
continuously from the showerhead or other outlets (the tank is full). Check connections are
free of water leakage, and insert the power plug.
Turn the knob to set your desired water heating temperature, which can be stepless changed
between cold water inlet temperature and 75
o
C. In heating mode, heating lamp is lighted on.
Normally the knob shall be positioned at highest temperature. This machine has a thermostat
function, which automatically switches off the water heater when temperature reaches the
setting value, and switch on again when water temperature decreases to certain value.
City water pressure 0.75 MPa will cause much water flowing out from safety valve pressure
relief vent. This is due to too big water pressure. Please ask after-sales service for correction.
