9. PREVENTIVE MAINTENANCE
An annual preventive maintenance schedule is recommended by FBD and should include the following steps:
A. Check the Fault Code History in the menu (Section 7.7). If there are repeated beater low errors, inspect
blades for damage (chips, cracks, warping, excessive wear) and dullness. The blade edge should be sharp and
smooth. If damage or dullness is found, replace blades using an FBD blade/spring kit.
B. Verify time, date, sleep, and defrost settings (Section 7.11). Adjust as necessary.
C. Clean air filter (Section 9.1).
D. Check all fittings and components for leaks. Repair if necessary.
E. Check O-ring seals in dispenser valves for leakage and wear. Replace as necessary.
For dispensers using the stainless-steel DDV, the roll pin needs to be changed during the annual preventive
maintenance. The SS DDV Minor Repair Kit (P/N 12-1140-0001) contains the roll pin and O-rings that are
recommended to be replaced. If the internal metal components show signs of wear, the SS DDV Major Repair
Kit (P/N 12-2307-0001) can be used to replace needed components. If the roll pin does not fit tightly with the
handle lever, replace the handle (P/N 12-2864-0012).
F. Replace the motor rear seals (Section 9.2).
G. Sanitize according to manufacturer’s recommended procedure (Section 8.3).
H. Check water flow rate and brix (Section 5.3).
9.1 Air Filter Cleaning
The air filter must be cleaned monthly to ensure proper operation of the dispenser. A dirty air filter will reduce the
refrigeration capacity and can potentially damage the compressor. To remove the filter, open the front merchandiser and
locate the filter above the LCD display. Pull the air filter straight out to remove. Clean it with a mild dishwashing soap and
water solution and dry thoroughly before reinstalling. A degreaser may be required if the filter is greasy.
NOTE: If the dispenser is located in a particularly dusty area or with airborne grease such as the cooking area of a fast food
restaurant, then the filter should be cleaned every two weeks.
