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 . 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 0.075 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.
To avoid causing machine troubles, do not connect power before tank is full of water.
Adjust a suitable temperature before use, for water temperature above 50 may burn
your skin.
Check safety valve once a month as follows: move 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.
This product is closed water heater, which can supply hot water through pipe connection
to several points like bathroom (bathtub, washbasin, showerhead) and kitchen.
Heating adjustment can be made flexibly all year round adapting to climate changes. In
long-term out-of-use or maintenance, you can close city water pipe valve, open mixing
valve, and move up safety valve handle to drain the tank. To avoid injury, before next use,
it is suggested to first open hot water valve before switching on the water heater,
exhausting gas possibly retained in the pipeline. In this case, no smoke or fire is
permitted near the open valve. Carefully check and confirm all parts are in good
condition.
Provided hot water quantity can meet use demand, temperature setting shall be possibly
low. It can minimize heat dissipation, high-temperature corrosion and sedimentation,
ensuring a longer service life.
Regularly ask servicemen to make safety inspection, remove sediment on heating
elements, and check consumption of anode bar. Too much consumed anode bar shall be
replaced.
This water heater shall only be repaired and maintained by qualified
servicemen. Improper maintenance may cause severe injury or damage.
Before opening or repairing water heater, please do pull out the power plug.
External Cleaning: Disconnect power supply before cleaning. Gently wipe with wet
cloth dipped with a little of mild detergent. Do not use gasoline or other solvents.
Finally dry with dry cloth. Keep water heater dry. Do not use cleansers containing
grinding agent (e.g. toothpaste), acids, chemical solvents (e.g. alcohol) or polishers to
clean.
