ATTANTIONS! 

The WHEL-3 series shall be used in a summer season 

with temperature of inlet water - +16-18°C

ATTANTIONS! 

Do not switch on the water heater, if you suspect 

freezing of water in it.

ATTANTIONS! 

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.

stabilized.
- 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.

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 

integrated 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 

actually, 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 

button 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).
