Check items
Situations might occur due to improper
installation
Does electric wire model meet
specification?
Malfunction might occur, or component is
burned.
Is safety valve installed in water inlet
pipeline?
Water tank operation pressure is high
with safety hazard; water will flow back
when pouring.
If water input pressure of tap water
is too high?
Water tank operation pressure is high,
safety valve keep leaving water and
occur abnormal noise.
When water input pressure is high,
is stabilizing valve installed in water
inlet pipeline?
Water tank operation pressure is high,
safety valve keep leaving water and
occur abnormal noise.
Is the water tank ground wire with
auxiliary electrical heating reliable?
Safety danger might occur.
Conduct debug after all the above items are qualified, the debug step is as
follows:
(1) Water tank water input
Conduct water input operation for the water tank according to 10.1 or the
installation tips label on water tank, and check if there is water leakage in pipeline
and joint. For initial installation, the installation debug personnel shall conduct this
operation, if the user reuse it after discharging water, water input operation is also
required for operation.
(2) Unit energization
When the unit is energized, you will hear a sound from the buzzer of displayer.
Observe if the displayer is normal without any error code. The displayer has
memory function when power off. For the first energization, the displayer might
display power off or standby. Please note that water must be supplemented fully in
water tank before energizing the unit. Do not energize it in advance.
(3) Engineer parameter setting on displayer
System clock time setting, etc.
(4) Unit operation
After water is full in water tank, check waterway system to ensure faucet or
sprinkler of user end is off, startup the unit for operation after turning on cut-off valve
of water inlet/outlet pipe of water tank, when the displayer displays heating icon,
check if the unit is operating normally. Standard criteria: the fan is operating
normally and the unit is operating stably, no obvious sway, no abnormal sound.
Deliver the unit to the user after normally operating for at least 20min.
