Water heater operation
- Feed water to the water heater and switch on electric power supply.
- Water flow is controlled by the mixer at the water inlet to the water heater. It is
prohibited to install a mixer and/or shut off water feeding at outlet from the
water heater.
- Water heating is activated using a switch (Fig.4; Fig.5)
- It is necessary to wait for 10-20 sec until temperature of heated water is stabi-
lized.
- To switch off the water heater, you can just shut off water flow at inlet to the
appliance. At that, the pressure sensor will automatically open the electric
power supply circuit to the heating element. To switch on the water heater
again, it is sufficient to just open the valve.
Water heater operation
Inlet water is heated, when it flows through the heating element inside the
vessel. Water temperature in the water mains may fluctuate throughout the
year from 3°C to 20°C.
To obtain the optimum temperature in winter, water flow shall be made lower
than in summer.
For adjustment of hot water temperature, you can use the valve at the inlet
connection (cold water inlet) changing water flow rate. When you decrease
inlet flow rate of water, you increase outlet temperature and vice versa.
- To switch on the appliance, it is necessary to place the switch to the "ON"
position ("Low" for WHEL-6/7 series)
- When the switch is in the "OFF" position - there is no heating.
- When the switch is in the "ON" position ("High" for WHEL-6/7 series) -
heating is maximum.
- To adjust water heating temperature, you can change flow rate of water
(using the flow control valve at the water inlet to the water heater).
- To switch off the appliance, place the switch to the "OFF" position and
close the cold water feed valve.
ATTENTION!
Do not switch on the water heater, if you suspect freezing of water in
it.
The water heater is equipped with the following instrumentation:
- The heating element is activated only at optimum water pressure in range
from 0.03 to 0.6 MPa. Its lower range value is automatically monitored by
the integrated pressure sensor.
If inlet pressure of water decreases excessively (below 0.03 MPa), the inte-
grated pressure sensor trips and disconnects power supply.
- Thermal switch: it will stop power supply to the heating element in the
event of water overheating in the water heater. If the water heater is
switched on and water heating is activated, but water is not heated actu-
ally, this means tripping or need for reset of the thermal switch. To return
the water heater to the operational condition, push the button on the
thermal switch. For that, use the following procedure:
Switch off the electric heater, remove the front panel, push the black but-
ton located at the center of the thermal switch until the button clicks (the
thermal switch itself is located from the right side of the water heater
vessel on the heating element).
ATTENTION!
If these actions do not give a positive result or the thermal switch
trips on repeated occasions for a short period of time, then switch
off the water heater, shut off water feeding to the water heater, and
contact the authorized service center of Timberk in your region for
consultation or repair of the product.
The address of the authorized service center can be obtained from
the vendor or at www.timberk.com.
ATTENTION!
The WHEL-3 series shall be used in a summer season with tempera-
ture of inlet water - +16-18 °C
