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.
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 .
