TROUBLESHOOTING (cont.)
Unit is not working and no beep/light
fault codes
Difficulty brixing and/or weak bev-
erage
1. Step-down transformer.
2. Main control board.
1. Product viscosity or too cold.
2. Low water pressure.
3. High water pressure.
4. Dispense valve adjustment set-
ting.
5. Brix ratio.
Check for 120/24 vac. If no 24vac
reading, replace step-down trans-
former.
If 24 vac present and no red LED,
replace control board..
Hint:
Red LED on main control board
is powered from the step-down
transformer 24 vac and rectified to
24 vdc by the rectifier.
Thorough thaw of product before
use (35° - 40°)
Maintain 20 psi or higher and a
minimum flow rate of 3 fl oz/sec.
Over 100 psi, install a pressure
regulator and set to 50 psi.
A) Perform 3 second water dispense
test. Factory setting is 1.0 oz/sec.
Acceptable water flow rate is .-0.8
to 1.5 oz/sec depending on the mix
ratio (4+1).
B) Adjust water to proper mix ratio.
Once water is set, adjust motor
speed (RPM) to achieve brix %.
Check for proper brix ratio per prod-
uct using Total Dispense method
and or refractometer method.
