Sequence of Operation
QFA-290 PUSHBUTTON OPERATED
ICE DELIVERY
Depressing the ice delivery push button allows
power to flow through the switch to the solid state
relay. The relay energizes and powers the windings
of the dispenser motor. This motor drives a
gearbox, which in turn drives a pulley. A toothed
positive-displacement v-belt is attached to the drive
pulley, a spring loaded tension pulley, and the
agitator and dispenser pulleys. The turning of the
augers causes the ice to ride to the top of the
dispensing auger, where it will open a door and
drop through the ice chute into the glass held
beneath the outlet.
When sufficient ice has been dispensed, the push
button is released and delivery stops.
WATER DELIVERY
Depressing the water delivery push button allows
power to flow through the switch to the coil located
on the water valve. The magnetic action of the
solenoid coil lifts the plunger off its seat on the
diaphragm. Water pressure forces the diaphragm
open allowing water to flow through the tubing and
out the water delivery spout.
When sufficient water has been dispensed into the
glass, the push button is released and delivery stops.
