Motor Seal Leak Test
After replacing the motor seal, it is advisable to test the seal under pressure
before refilling the barrel with product. Perform the procedure in Table 44 to ver-
ify that the seal is installed properly and not leaking. When the seal passes the
leak test, perform the motor calibration routine on page 35.
BARREL MOTOR REPLACEMENT
The barrel motor does not require any special alignment when being replaced. It
mounts on four (4) bolts. These bolts are screwed into threaded bosses in the
foam pack barrel assembly, as shown in Figure 43. To replace a barrel motor,
perform the procedure in Table 45.

Step Action

surizes the barrel with CO
2.
3 Observe the water and syrup fill solenoids.
4 If there are NO seal leaks, these solenoids cycle off within a minute and
remain off.
5 If the solenoids cycle off and remain off, the barrel seal is not leaking and the
barrel is ready to be filled with product.
6 If the solenoids do not cycle off, or cycle off and on, the seal is leaking and the
seal installation process described in Table 42 and Table 43 must be rea-
peated.
7 If there are no leaks, turn the 3-way Product Supply valve to the BRIX posi-
tion.
