GENERAL FEATURES
POWER SWITCH
Controls the power as 3 different level (3,4,7 kW) to adjust the water
temparature.
INDICATION LAMPS
The lamp at the top indicates the power, the other lamps indicate power
levels.
DIAPHRAGM GROUP
This sophisticated group controls the power depending on the differen-
tial pressure on both sides of rubber membrane. It shuts of the power
when the differential pressure is not enough.
THERMOSTAT
Prevents the over heating of the water by shutting off the heating
element.
RESET THERMOSTAT
It is a double safety feature for over heating. If thermostat is failed its
function, reset thermostat prevents over heating.
HOW TO OPERATE
1. Turn on the water tap. (Figure 1)
2. Adjust the flow rate by using the spherical valve. (Figure 2)
3. Depending on the season and water temparature desired, the selector
switch should be positioned to the desired level of 1,2 or 3.
4. To turn off your water heater, the power selector switch should be at
“0” position first. Wait until water cools down.
5. When water cools down, close the water tap.
6. This shut off prosess will protect the heater resistance against lime
scale deposits resulting decrease on heating and resistance failure.
