Setting the Mix Hopper Temperature
1. To set the mix hopper temperature, fill the
hopper at least half full with approximately 40° F (4.4°C)
mix.
2. Install a suction pressure gauge at the EPR valve
(evaporator pressure regulator) and verify the correct
operating pressure. Adjust if necessary.
3. Set the "MIX" potentiometer to mid-range.
4. Allow the mix hopper refrigeration system to cycle until
the mix temperature is stabilized. Adjust the setting if
necessary.
Note:
On the Models 336, 338, 339, 754 and 794, the
temperature adjustment must be made on the left logic
board.
Standby Adjustment
Maintains mix temperature in the freezing cylinder during
long "no sale" periods to prevent over-beating of the product.
Ideal standby temperature = 30°F (1.1 °C) to 35°F (1.7°C).
Cut-out temperature will always be 4°F (2°C) lower than the
cut-in temperature.
The range for cut-in temperature is "MIN" approximately 44'F
(6.6'C) and "MAX" approximately 30-F (-1,1'C).
Setting Standby Temperatures
1. With the unit properly primed with fresh mix, turn the
STANDBY adjustment screw to the warmest position.
2. Press "STANDBY".
3. When the main refrigeration system cycles off, draw a
sample portion and check the product temperature.
4. To get the desired standby temperature, make a slight
clockwise adjustment and wait until the main
refrigeration cycles off.
Note:
On pump units, "STANDBY" must be cancelled and
"PUMP" must be pressed to replace the portion which was
used for the sample draw.
