Service Department for help, [phone] or (800)
695-4500 (USA & Canada only) 8 AM - 6 PM EST.

Cleaning and Sanitizing

All equipment in the system requires periodic
sanitization. The frequency of this procedure is
dependent on the water condition, temperature, and
concentrate type.

Sanitize in accordance with local health department
regulations. Grindmaster-Cecilware recommends
cleaning and sanitizing at least every week.

Materials required:

• Non-sudsing liquid detergent (such as common
household automatic dishwasher liquid
detergent)

• Sanitizing agent. Recommended sanitizer ­bleach, Sodium Hypochlorite

• Clean five (5) US gallon [19 liter] bucket or
container

• Five (5) US gallon [19 liter] bucket or container
for used detergent/sanitizer

• Measuring cup

• An adapter fitting on the concentrate suction
line to allow sanitizing agent to enter the
autofill. A connector cut from an empty liquid
concentrate will work.

Cleaning

1. Turn power switch to “OFF” on Autofill unit and
empty bowl. For Bubbler, detach probe from control
line and clean and sanitize separately. For Granita,
turn off power to Granita.

2. Fill the bucket with four (4) gallons [15.14 L] of
liquid detergent mixed with warm water (120 ­180°F) [48-82°C]. Measure four (4) ounces (½ cup)
[118cc] of the liquid detergent and add to the
water.

3. Disconnect the outlet hose from the beverage
dispenser. Place an empty container under the
output hose.

4. Disconnect the concentrate line from the liquid
concentrate supply and install the adapter on the
quick disconnect so the line is open to the cleaning
solution. Place concentrate line into the bucket of

Installation (continued)

NOTICE: All sanitizing agents in the food zone must

comply with 21 CFR 178.1010.

NOTICE: Concentrates that contain pulp,

particulates, or solids will require more frequent
sanitation to prevent build-up. Concentrates with
especially “stringy” pulp will require even more
frequent sanitation.

WARNING: Do not alter or deform the plug in

any way! Altering or deforming the plug may cause
electrical shock, damage unit and will cause personal
injury.

18. Dispose of contents of the bucket and rinse bucket.

Before you call for help, please read the following:

I. PUMP WILL NOT CYCLE:

• Verify there is adequate water pressure (30-50
psi.[2-3.4 bar]) at water inlet fitting.

• Verify that the dispenser valve operation
(switch/solenoid), passages, and lines are
unrestricted. Flush and sanitize pump and outlet
lines from pump fittings to the dispenser if
restricted.

• Check for liquid in the liquid concentrate supply. If
empty, replace with new box of concentrate.

• Check for plugged, kinked, or restricted inlet
tubing. Flush and sanitize pump and outlet lines
from pump fittings to the dispenser if restricted.

• Verify electrical connection, plug is properly seated,
and power switch is turned on.

II. NO CONCENTRATE (PUMP CYCLES) / IMPROPER

BRIX:

• Verify that the concentrate passage is opening

completely when installed on the B-I-B connector. If
concentrate is supplied from a tank, verify that the
vent is open.

• Inspect for vacuum leaks at the concentrate inlet
side. Carefully look for air bubbles at connections
and fittings while the pump is cycling.

• Determine if there was air packaged with the
concentrate when the bags where filled. Stand the
box up on end and pull the connector up, allowing
air to rise up to the bag connector. Install liquid
concentrate fitting and engage it on the bag
connector opening the passage. Slowly press the
bag down, expelling the air until concentrate
appears, release and remove the liquid concentrate
fitting.

• Inspect for debris or improper closing of the liquid
concentrate fitting that interferes with their
operation.

WARNING: To reduce the risk of electrical shock, unplug the power cord before repairing or replacing

any internal components of the unit. Before any attempt to replace a component, be sure to check all electrical
connections for proper contact. Only a qualified service technician should perform electrical and mechanical
adjustments or repairs.

III. PUMP CYCLES INTERMITTENTLY/ WILL NOT

SHUT-OFF/ DRIPS:

• If the pump continues to cycle after liquid
concentrate supply has emptied, verify that there
are no vacuum leaks.

Determine if the concentrate bag has an excessive
(more than 1 cubic inch [16.4 cc]) amount of air.
NOTE: If the concentrate is moved above the pump,
head pressure from the liquid concentrate may be
substantial enough to cause the dispenser to drip.

Valve Inspection

Some concentrates, after prolonged periods of contact
without regular sanitizing, may cause the valves to
become stiff or clogged with pulp and/or particulates.
If a situation of this type is suspected, valve cartridges
(4 each) can be removed for inspection.
Turn off water supply valve and relieve pressure.

Remove each assembly by loosening the screw holding
the cartridge. Turn the cartridge and then pull it out of
the housing (use of tools may be required).
