CHECKING ACTIONS
1. Ensure power supplier availability, by checking
OFF
house power supply voltage;.
1. Ensure water flow rate is big enough (over 1,2L/
min);
2. Ensure the water heater is turned ON, by rby
OFF pressing ON/OFF button;
3. Ensure product is not in cold water model;
4. Ensure water pipe connection (inlet on right, out-
let on left). fig 5
Ensure water flow rate is not too big (over 6L/min),
ON by reducing the flow rate through water supply
valve;
Ensure "TEST" button is not wrongly pressed, press
OFF
the "reset" button to light ON the ELCB lamp.
OFF Stop use the water heater, call service.
-- Stop use the water heater, call service.
1. Increase temperature/power setting.
2. Ensure the water flow rate is not too big (over 6L/
min), by water supply valve; if flow rate too big,
outlet water will not able to reach the setting
temperature;
ON 3. Measure the actual voltage WHEN heating to
make sure voltage drop not too big. By increase
section, or reduce length of the power supply ca-
ble could improve.
4. Ensure power supplier voltage not too small, by
checking house power supply WITHOUT heating.
1. Ensure the water pressure is big enough to pro-
vide comfortable water flow rate.
2. Ensure there are no dirty, by clean the filter, which
--
is built in the water supply valve. Fig. 5, B1-B2-B3
3. Ensure there are no bottleneck in the inlet pipe
between water heater to the main water supply
point;
Measuring the actual voltage WHEN heating to
make sure voltage drop not too big. (Voltage drop
ON should be less than 10%).
By increase section, or reduce length of the power
supply cable could solve the flickering problem.
