6. To drain water from the internal tank properly, you need to use the drain 
hole (only for FSM2/FSQ2 line) (it is necessary to unscrew a plug, covering 
the drain hole), water can also be drained through a composite relief valve 
(Fig. 11) (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.

8. If necessary, wipe external surfaces of the heater by a damp cloth with 
soap.
