DISPENSER INSTALLATION HIGHLIGHTS
Listed below are seven critical elements which will aid in a successful installation.
1. Fill water bath until water overflows from tank overflow tube.
2 If this dispenser is installed in an area that is susceptible to ±10% variation of the nominal line voltage,
consider installing a surge protector or similar protection device.
3. There is a five (5) minute delay which prevents the compressor and condenser fan from starting until the
delay has lapsed. If electrical current is interrupted, there is always a five (5) minute delay before the
compressor starts.
4. Supply Water Pressure: Minimum - 40 PSIG (2.76 BAR); Maximum - 110 PSIG (7.58 BAR). If pressure is
over 110 PSIG (7.58 BAR), a water pressure regulator must be used.
5. On units with the built in water regulator, the regulator must be removed if inlet water pressure is less than
40 PSIG (2.76 BAR).
6. CO2 Pressure for syrup pumps: Recommend nominal pressure 70 PSIG (4.83 BAR). Pressure may be
reduced to a minimum of 60 PSIG (4.13 BAR) if remote syrup pumps are being used. It may be increased
to a maximum of 80 PSIG (5.52 BAR) for highly viscous syrups.
7. Valve Adjustment: Make sure drink temperature is below 40°F (4.4°C) before adjusting brix.

3. DISPENSER CLEANING AND SANITIZING
3.1 GENERAL INFORMATION
A. Lancer equipment (new or reconditioned) is shipped from the factory cleaned and sanitized in
accordance with NSF guidelines. The operator of the equipment must provide continuous
maintenance as required by this manual and/or state and local health department guidelines to
ensure proper operation and sanitation requirements are maintained.
NOTE
The cleaning and sanitizing procedures provided herein pertain to the Lancer equipment
identified by this manual. If other equipment is being cleaned, follow the guidelines established
by the manufacturer for that equipment.
IMPORTANT
Water lines are not to be disconnected during the cleaning and sanitizing of syrup lines to avoid
contamination.
B. Cleaning and sanitizing should be accomplished only by trained personnel. Sanitary gloves are
to be used during cleaning and sanitizing operations. Applicable safety precautions must be
observed. Instruction warnings on the product being used must be followed.
C. Recommended Preparation of Cleaning Solutions.
1. Cleaning solutions (for example, Ivory Liquid, Calgon, etc.) mixed with clean, potable water
at a temperature of 90° to 110° Fahrenheit should be used to clean equipment. The
mixture ratio, using Ivory Liquid, is one (1) ounce of cleanser to two (2) gallons of water.
A minimum of four (4) gallons of cleaning mixture should be prepared.
NOTE
Extended lengths of product lines may require that an additional volume of solution be
prepared.
2. Any equivalent cleanser may be used as long as it provides a caustic based,
non-perfumed, easily rinsed mixture containing at least two (2) percent sodium
hydroxide (NaOH).
D. Recommended Preparation of Sanitizing Solutions.
1. Sanitizing solutions should be prepared in accordance with the manufacturer’s written
recommendations and safety guidelines. Follow manufacturer’s requirements so that the
solution provides 200 parts per million (PPM) available chlorine at a temperature of 90°F to
120°F. A minimum of four (4) gallons of sanitizing solution should be prepared.
NOTE
Extended lengths of product lines may require that an additional volume of solution be
prepared.
2. 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 200 parts per
million (PPM) available chlorine.
3.2 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 low pH (7.0)
chlorine solution.
B. Disconnect syrup containers and remove product from tubing by purging with carbon dioxide.
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 manufacturers
recommendations, but should be at least 2 percent (2%) sodium hydroxide. Make sure the lines
are completely filled and allow to stand for at least 10 minutes.
E. Flush the detergent solution from the lines with clean water. Continue rinsing until testing with
phenolphthalein 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 50 PPM (50 mg/L) chlorine.
Make sure that lines are completely filled and allow to stand for 10 minutes.
G. Reconnect syrup containers and ready Unit for operation.
H. 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.
I. Taste the beverage to verify that there is no off taste.
3.3 ALTERNATE CLEANING AND SANITIZING AGENTS
The above approach to cleaning and sanitizing is strongly recommended. However, the Division
Quality Assurance Manager may approve the following cleaning and sanitizing agents.
A. Chlorinated alkaline detergents. These compounds may be used as the cleaning agent, but
may not be used as combined cleaner/sanitizer.
B. Iodophors may be substituted for chlorine as the sanitizing agent.
CAUTION
IODOPHORS AND QUATERNARY AMMONIUM COMPOUNDS (QUATS) ARE BROAD CLASSES
OF COMPOUNDS. SOME MEMBERS OF EACH GROUP CAN CAUSE SERIOUS PROBLEMS
WITH FOAMING, DISTORTION OR DISCOLORATION OF POLYMERIC PARTS, POOR
RINSIBILITY, AND OFF-TASTE. THE RINSIBILITY AND OFF-TASTE PROBLEMS HAVE BEEN
ESPECIALLY PREVALENT WITH QUATS. BECAUSE OF THE POTENTIAL PROBLEMS,
APPROVAL MUST BE GRANTED BY THE DIVISION QUALITY ASSURANCE MANAGER TO
SPECIFIC COMPOUNDS. THIS APPROVAL SHOULD BE BASED UPON TESTING IN THE
LABORATORY.
C. Quaternary ammonium compounds may be used as a combined cleaner-sanitizer but are
generally not recommended. These compounds are not to be utilized at concentrations
