6. To drain water from the internal tank properly, you need to use the drain
hole (only for FSM6/FSM4 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.
