The safety valve should be connected to the 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.
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 for fear of indoor contamination. The hose
can be cut short or extended as necessary. The hose shall be installed as inclined downward.
The heater should work with the safety valve whose rated pressure is 0.80MPa.
During heating, water may drip from the drain hose of the pressure relief hole due to
expansion and the hole must be left open to the atmosphere. Check safety valve once a
The pressure relief hole is to be operated regularly to remove lime deposits and to verify that it is not blocked.

illed with water. Do not secure it
by means of adhesive or similar products because the f
ixation by such methods is unreliable.

Safety precautions
Please fasten the drain hose to the pressure relief hole of the safety valve by twisting (see to
Figure 4). Connect the other end of drain hose to the sewer to avoid polluting the room by
splashing. When the power is switched on, and the water heater starts operating, there may
be some water discharged from the pressure relief hole of the safety valve. It is due to the
water expansion under heating, and is a normal phenomenon. The pressure relief pipe shall
communicate with the air directly. Do not block it. The drain hose connecting to the safety
valve shall be kept downward sloping in installation and in a frost-free environment.
Be sure to check and conf
irm that the tank is f
illed with
water, there is no leakage at each joint and the power supply
complies with the stipulation before switching on the power.
This heater must be equipped with the safety valve along
with the machine; otherwise any safety accident and property
loss caused thereby shall be the user's own responsibility.
To avoid danger caused by accidental resetting of the heating breaker, the power for the heat
cannot be supplied by timer and other external switch devices or connected to circuit with
frequent switching for facility use.
If any part is damaged, please contact the local maintenance agent and have it replaced with
our spare parts.
Tap water inlet pressure shall be no less than 0.05MPa and the maximum pressure shall not
exceed 0.75MPa.
After installation, as the tank is empty in the f
irst usage, be sure to open the tap water inlet
valve and turn to the top temperature button on the mixing valve. When the tank is f
illed
with water, and the shower nozzle or other water outlet keeps the water output, please close
the mixing valve, check if there is water leakage at each joint and plug the power.
Turn the knob as per the needed water temperature. The setting temperature rises gradually
when the temperature regulating knob is rotated clockwise; when setting to the maximum
temperature, the knob cannot be rotated any more; the temperature decreases gradually in
case of anticlockwise rotation of the knob. The mark of the knob increases from the actual
temperature to 75
o
C. You can set the heating temperature steplessly. The heating indicator
will light on under heatin
g mode. Generally, the knob should be set to the highest scale. The
automatically when the set temperature is reached, and will be switched on automatically when
the temperature drops to a certain level. As it continues heating, you can use hot water as well.
When the tap water inlet pressure arrives at or exceeds 0.80MPa, the drain hose of safety
valve will discharge a large amount of water. It is due to extra high water pressure. Please
contact the local after service agent for disposal.
In long-term out-of-use or maintenance of the heater, you can close the city water pipe valve
and set the mixing valve to the highest water temperature rate after opening the safety valve
handle. Move up the safety valve handle to drain the tank. To avoid injury, before the next
use, it is suggested to f
irst open hot water valve before switching on the water heater, exhaust
gas possibly retained in the pipeline. In this case, no smoke or f
ire is permitted near the open
valve. Carefully check and conf
irm all parts are in good condition.

Cleaning and maintenance
FAQ
Disconnect power supply before cleaning. Gently wipe with wet cloth dipped with a little
mild detergent. Do not use gasoline or other solvents. Finally dry with a dry cloth. Keep
water heater dry.
iciency, heating elements and tank liner of water heater shall be
cleaned once every three years. Take care not to damage the protection layer on heating
elements and tank liner surface. According to the local water quality, magnesium rod shall
be periodically replaced. If maintenance is needed, please contact a local service station.
