1. Check the power plug and outlet as often as possible. Secure electrical 

contact and also proper grounding must be provided. The plug and outlet 

must not heat excessively.
2. If the water heater is not used for a long time, especially in regions with 

low air temperature (below 0°C), it is necessary to drain water from the 

heater .
3. To ensure long reliable water heater operation, it is recommended to 

regularly clean the internal tank and remove deposits on the electric heating 

element of the water heater, as well as check condition of the magnesium 

anode and, if necessary, replace it with a new one.

4. Preventive operations must be performed upon strict observance of the 

operation manual and safety precautions.
5. The water heater is equipped with a thermal switch, which cuts off power 

supply of the heating element upon water overheating or its absence in the 

water heater. If the water heater is connected to the mains, but water is 

not heated and the indicator doesn’t light up, then the thermal switch was 

switched off or not switched on. To reset the water heater to the operating 

condition, it is necessary to:
- de-energize the water heater, remove the plate of the side / lower cover 

for horizontal-type/vertical-type water heater respectively. 
- for FSM2/FSQ2 series horizontal-type water heaters: press the button, 

located in the center of the thermal switch, placed near the heating element 

(with a round shape), until it clicks, Fig.12;
- for FSM1/FSQ1 series vertical-type water heaters: unscrew retaining 

nut of the thermal switch, fastened on the flange of the heating element, 

turn the thermal switch and press the button, located in the center of the 

thermal switch, until it clicks; Fig. 13;
- if the button is not pressed and there is no clicking, then you should wait 

until the thermal switch cools down to the initial temperature.

IMPORTANT! 

The manufacturer provides an extended guarantee 

for particular water heater components provided that 

timely and proper routine maintenance is performed 

by specialists of an authorized service center (see the 

guarantee card).

IMPORTANT! 

If these actions had no positive result or the thermal 

switch turns off repeatedly during a short period of 

time, then you should de-energize the water heater, 

cut off water supply and contact your local Timberk 

Authorized Service Center for a consult or repair of the 

appliance.

3. Temperature display (only for FSQ series)

All FSQ series models are equipped with temperature display shows 

current water temperature in whater haeter tants. 

IMPORTANT! 

Water may start dripping from the relief valve hole 

during heating. It is impossible to avoid water leakage 

and you must not prevent it since valve blocking 

may cause rupture of the internal tank (in case of 

equipment failure).
