A.3.4 Function: Water Inlet into the Boiler
Fig. 1
• The water inlet into the boiler is regulated
by means of a floater washer (1) (fig. 1):
• The floater washer is suspended above the
spring supported float switch lever (2) by
means of a stainless steel wire. Depending
on the changing water level in the boiler it
moves upwards or downwards. (Fig. 1)
• When the water level in the boiler is low,
the floater washer pulls the float switch
lever downwards. The float switch connects
the water inlet circuit (output of 24 VAC).
• The inlet valve opens (3). (Fig. 1)
• Water from the supply lines runs through
the inlet spout and the non-return valve (4)
from below into the boiler. (Fig. 1)
• With increasing water level, floater washer
moves upwards and the float switch lever is
released. The water inlet circuit is opened
and the water inlet stops.
• In this way, the water level is kept at a
constant level while the dispenser is
operating.
