Recommended Daily Cleaning - Bunn ULTRA-1 Installation & Operating Manual

RECOMMENDED CLEANING (ULTRA-2 shown)
Frequency of cleaning should be as directed by the product manufacturer.
1. Turn cooling to OFF selection. Empty all product from the hopper(s). Turn auger to OFF selection. Disconnect the hop-
per lid lamp cord(s) and remove the lids. On models with autofill, disconnect fill hoses and level probe from hopper.
2. Depress the hopper lock plunger.
Lift the hopper up slightly.
5. Remove the cooling drum seal
from the rear of the drum.
8. Remove the auger nose bushing
from inside the hopper.
10. Place all parts in a clean sink with mild hot water (120°F) and sanitizer solution. Allow all parts to soak for at least 5
minutes. Carefully wash all components with a clean wash cloth in the hot water and sanitizer solution. Use a clean,
soft bristle brush as needed for the smaller components and tight areas. Do not immerse hopper lids. Use a com-
mercial sanitizer that has 100 ppm of available chlorine with a concentration level of at least 3% available chlorine
(KAY-5 Sanitizer). Follow the sanitizer's mixing instructions to ensure 100 ppm of available chlorine.
11. Wash the drums, hopper drip trays, top covers, and outer enclosure using a clean wash cloth that has been dampened
in the hot water and sanitizer solution. Pay particular attention to the shaft area and make sure it is thoroughly cleaned
and sanitized.
12. Thoroughly rinse all surfaces with a clean wash cloth that has been dampened with hot water. Wipe dry with a clean
dry wash cloth before reassembling the dispenser.
NOTE – Although most parts are dishwasher safe, they may be affected by the chemicals in some commercial sanitizing
agents. Do not place the hopper nor hopper lids in a dishwasher. Rinse thoroughly before assembly.
3. Pull forward to remove.
6. Caution: The faucet valve is under
spring tension. Spread one side of
the handle first, then the other and
disconnect from the hopper.
9. Care must be taken to ensure this surface does not get scratched during
cleaning. Deep scratches could cause leakage around the seal.

4. Pull the auger from the cooling
drum.
7. Carefully slide the faucet valve up
to remove the spring and faucet
seal. Extra care should be taken
when handling the seal to prevent
damage. Do not fold the seal as
this will cause damage to the
Teflon ® sealing surface.
