TRANSFORMER
WATER INLET SOLENOID
DOOR SWITCH - 72 B SERIAL NUMBER
This is a dual stage transformer with 2 outputs.
The purpose of the transformer is to step the
line voltage to 26 VAC primary to the electrical
box and the VRB and 24 VAC secondary is to
light the merchandiser.
Current production transformers are equipped
with a thermal overload protection device that
will cut out when high temperature or high
amperage is detected. THE OVERLOAD
RESETS AUTOMATICALLY
The water inlet solenoid is connected to the
incoming water line and is only activated when
the dispense button is pressed. The water inlet
solenoid prevents backflow and is equipped
with a strainer screen that needs to be
removed and cleaned once a year.
NOTE: THE INLET SOLENOID COIL IS
ACTIVED FROM THE VRB BOARD USING
THE 28VDC.OUTPUT AN AC COIL WILL
NOT WORK IN THIS APPLICATION.
The door switch on the 72B serial number units
is a combination of a door latch and switch. The
primary function of the door switch is to inter-
rupt the 26 VAC coming into the VRB board
when refilling the concentrate. By cutting this
voltage the refill lights are reset automatically.
NOTE: WHEN THE DOOR IS OPEN THE DIS-
PENSE CIRCUIT IS INOPERABLE DO NOT
ATTEMPT TO DEFEAT THIS WITH ANY-
THING. BUT THE CAM-LOCK FOUND ON
THE DOOR. A SPECIAL TOOL IS AVAIL-
ABLE FOR THIS PURPOSE.
