Programming Jumpers
Interface Board
W5
If a jumper is present on the left interface board, the real time clock can be changed in any
mode.
W4
Installing a jumper on the left or right interface board forces the liquid solenoid valves, the hot
gas soleniod valves, and the suction solenoid to be energized on the corresponding side of the
unit. Removing the jumper ends their operation. This is used for reclaiming and evacuation of
the refrigeration system only, or manual cycling of the solenoid valves for service check.
W3
A jumper on the W3 of the left interface board enables the syrup heaters.
W2
If a jumper is present on the left interface board, it resets the brush clean date. If a jumper is
present on the right interface board, it enables the 59°F(15°C) product temperature fault.
