6. Water can be drained through a composite relief valve (Fig.9 ) (unscrew
the composite relief valve drain knob screw and set the drain knob to the
upper position, at that hot water tap must be open, and cold water supply
valve must be closed).
7. Bear in mind to check serviceability of the relief valve every 14 days –
inspection method:
- turn the discharge lever to the left up until you feel the change of thread,
then water must start flowing from the valve’s hole. After checking the
water flow, return the lever to its initial position.
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.
IMPORTANT!
Never drain water if its temperature is over 50°C since
it may result in burns.
8. If necessary, wipe external surfaces of the heater by a damp cloth with
soap.
IMPORTANT!
If water doesn’t flow, then the valve is damaged.
In this case you must not use the heater and it is
recommended to call for a service technician.
