manual.

4. DISPENSER CLEANING AND SANITIZING

4.1 AMBIENT PROCESS

A. The ambient process is the most common method for cleaning and sanitizing dispenser

equipment. The detergent should be caustic-based and the sanitizer should be a low pH (less

2

than 7.0) chloride solution.
B. Disconnect syrup containers and remove product from tubing by purging with water.
C. Rinse the lines and fittings with clean, room temperature water to remove all traces of residual

product.
D. Fill lines with a caustic-based (low-sudsing, non-perfumed, and easily rinsed) detergent solution.

The solution should be prepared in accordance with the manufacturer's recommendations, but

should be at least two (2) percent sodium hydroxide. Make sure the lines are completely filled

and allow to stand for at least ten (10) minutes.
E. Flush the detergent solution from the lines with clean water. Continue rinsing until testing with

phenolpthalein shows that the rinse water is free of residual detergent.
F. Fill the lines with a low pH (7.0) chlorine solution containing at least 100 parts per million (PPM)

(100 mg/L) available chlorine. Make sure that lines are completely filled and allow to stand for

ten (10) minutes.
G Nozzle/Diffuser Sanitizing

Use the following procedure to sanitize the nozzle housing during dispenser sanitization.

1. Cleaning Solution - Prepare a low sudsing, non-perfumed, and easily rinsed detergent

solution and clean, potable water at a temperature of 90° to 110°F.

2. Sanitizing Solution - Prepare a chlorine solution (less than pH 7.0) containing 100 PPM

available chlorine with clean, potable water at a temperature of 90° to 110°F. Any sanitizing
solution may be used as long as it is prepared in accordance with the manufacturer's
written recommendations and safety guidelines, and provides 100 PPM available chlorine.

3. Cleaning Procedure

CAUTION

BE CAREFUL NOT TO GET SANITIZING SOLUTION ON THE CIRCUIT BOARD.

a. Disconnect power, so the valve will not be inadvertently activated while cleaning.
b. Remove nozzle housing by twisting it counter-clockwise and pulling it down.
c. Wash the nozzle housing with the cleaning solution.
d. Immerse the nozzle housing in a bath of the sanitizing solution for 15 minutes.
e. While the parts are in the sanitizing solution, visually inspect around the nozzle

mounting area for syrup residue. Using a cloth or nozzle brush and sanitizing solution,
clean this area and the bottom of the nozzle body.

f. Wipe off the valve shroud assembly and any other areas that may have been splashed

by syrup.
g. Wearing sanitary gloves, remove, drain, and air dry the nozzle housing.
h. Make certain the nozzle o-ring is in place around the nozzle mounting area on the valve.

If necessary, slide a new nozzle o-ring (PN 02-0228) onto the nozzle mounting area.

(Wear sanitary gloves while handling the o-ring.) If needed, apply 111 lubricant (or

another FDA approved lubricant) to the o-ring.
i. Wearing sanitary gloves, install the nozzle housing by inserting it into the nozzle body

and twisting it clockwise to lock it in place.
j. Connect power and replace cover.
k. Reconnect syrup containers and ready Unit for operation.

W

ARNING

REMOVE SANITIZING SOLUTION FROM DISPENSER AS INSTRUCTED. RESIDUAL
SANITIZING SOLUTION LEFT IN SYSTEM COULD CREATE HEALTH HAZARD.

l. Draw drinks to refill lines and flush the chlorine solution from the dispenser.

NOTE

Please note that a fresh water rinse cannot follow sanitization of equipment. Purge only

with the end use product. This is an NSF requirement.

m. Taste the beverage to verify that there is no off taste.

5. OPERATION OF THE LFS

5.1 CONNECTIONS

A. Attach 3/8” syrup hoses between syrup (BIB), syrup pump, and the unit. Inlet syrup hose, 3/8”,

attaches to left side of unit.

dispensing syrup and water out of the valve.

5.4 MANUAL MODE

A. Switch the unit in MANUAL Mode (this requires holding down the switch). The Green power light

will come on and the valve will start dispensing syrup and water out of the valve.

5.5 SETTING THE DESIRED RATIO

The ratio of BIB slush for Sonic should only be set at 4.5:1. This is the approved ratio

for this product. Use the special 4.5:1 and 5.0:1 Ratio Cup to target (Coca-Cola

PN 15507). Follow the same valve ratio targeting method that is used to set the LEV®

for fountain dispensing.

IMPOR

TANT NOTE TO TECHNICIAN:

Failure to properly set the LFS LEV® for 4.5:1 ratio can result in damage to the

customer-owned slush dispenser. Low brix (high ratio) can lead to barrel freeze up

and subsequent motor/part damage. High brix (low ratio) can lead to longer than

normal freeze down times.

A. ADJUSTING WATER FLOW

The Model 145 LEV

® water flow may be adjusted from 2.0 oz/sec (59.2 ml/sec) to 4.50 oz/sec

(133.2 ml/sec). The restricted flow adjustment plug adjusts to a maximum flow of 3.3 oz/sec

(97.7 ml/sec).

1. Slide I.D. panel UP until flow control adjustments are exposed (see Figure 2).

2. Remove nozzle by twisting counter clockwise and pulling down.

3. Remove diffuser by pulling down.

4. Install Lancer syrup separator (PN 54-0201, smoke, for Model 145 valves) in place of the
nozzle.

5. Activate valve to fill separator syrup tube.

6. Hold a Brix cup under syrup separator. Dispense
water and syrup into cup for two (2) seconds. Divide
number of ounces (ml) of water in cup by two (2) to
determine water flow rate per second.

7. To obtain desired water flow rate, use a screwdriver
to adjust water flow control (see Figure 2).

B. ADJUSTING WATER TO SYRUP BRIX

The Model 145 syrup flow may be adjusted from 0.50
oz/sec (14.8 ml/sec) to 0.90 oz/sec (26.6 ml/sec).

1. Hold the Brix cup under the syrup separator and
activate valve. Check Brix.

5.8 FUNCTIONS AND ALARMS

A. Probes monitor the level of product in the hopper if the level of product flows below the Lo

probes then the valve comes on and begins filling the hopper until contact is made with both Lo
probes plus an additional 17 seconds after that and then shuts off. If the level of product ever
comes in contact the Hi probe then the valve shuts off until the level drops below this probe.
(Applies for AUTO and MANUAL Mode.)

B. Sold out Alarm monitors the amount of syrup in the bag in the box when the level is low the

pressure switch activates and triggers an alarm and red led light which will blink. The alarm can
be turned off by replacing the bag in the box, changing the CO

2 bottle or switching the unit in

MANUAL.

NOTE:

By switching the unit in MANUAL and then back into AUTO, you turn the sound alarm only OFF.
The red SOLD OUT switch continues to blink until one of the above is performed.
