WARNING!
1. INSTALLATION OF LANCER ICE COOLED DISPENSER
1.1 RECEIVING
Each unit is tested under operating conditions and inspected before shipment. At the time of
shipment, the carrier accepts responsibility for the unit. Upon receiving the unit, carefully inspect the
carton for visible damage. If damage exists, have the carrier note the damage on the freight bill and
file a claim with carrier. Responsibility for damage to the unit lies with the carrier.
1.2 UNPACKING
A. The ice cooled dispenser is shipped in a corrugated shipping carton. Remove the corrugated
shipping carton from the unit.
B. Remove the parts from the ice compartment.
C. Inspect the unit and parts for concealed damage. If damage exists, notify delivering carrier and
file a claim.
1.3 SELECTING A COUNTER LOCATION
A. Select a counter location close to a properly grounded electrical outlet and a water supply that
meets the requirements specified in Section 1.4 below.
B. The counter location must be able to safely support a minimum of 365 pounds (165.5 kg) after
the counter cutout is made.
1.4 WATER SUPPLY
A. Provide an adequate potable water supply The water supply line must be at least a 1/2 inches
(12.7 mm) pipe. Water pressure exceeding 50 PSI is regulated by a pressure regulator on the
pump deck. Water pressure below 40 PSI will require a booster pump.
B. Install a shut-off valve in the water line feeding the deck. If a separate water line is run for plain
water, ensure that it also has a shut-off valve.
3
P.N. 28-0720/05
Use a filter in the water line to avoid damage to the dispenser.
WARNING!
C. The carbonator pump is equipped with a strainer on the inlet side. A water supply containing any
appreciable quantity of silt, fine sand, or other debris requires a filter ahead of the pump deck.
Clean the filter cartridge periodically, depending on the condition of the water. Failure to do so
may starve the pump of water, causing it to burn out, and voiding the warranty.
1.5 ELECTRICAL SUPPLY
The dispenser must be properly electrically grounded to avoid serious
injury or fatal electrical shock. The power cord has a three-prong grounded
plug. If a three-hole grounded electrical outlet is not available, use an
approved method to ground the unit. Follow all local electrical codes when
making connections. Each dispenser must have a separate electrical circuit.
Do not use extension cords. Do not connect multiple electrical devices on
the same outlet.
ALWAYS disconnect power to the dispenser before attempting any internal
maintenance.
Only qualified personnel should service the internal components of the
dispenser. Avoid any contact with water when plugging in the dispenser.
A. Locate a standard 20 AMP, 110 VAC, 60 Hz single phase electrical power outlet with ground
connectors for the dispenser and pump deck.
1.6 INSTALLATION OF THE DISPENSER AND PUMP DECK
A Inspect the counter location where the dispenser will be installed. Verify that the counter is
strong enough to safely support a 365 pound (165.5 kg) load, after the counter cutout is made.
B. Verify that the unit will fit in the location. See below for the counter cutout dimensions.
NOTE: The unit can extend up to 23 inches (58.42 cm) below the counter, including the shipping
risers. It is recommended to keep the shipping risers attached to the dispenser. If the
dispenser ever requires removal, the shipping risers will protect the inlet tubes from being
damaged.

C. After the counter cutout is made, lower the dispenser into the counter.
NOTE: In order to ensure unit drainage and proper carbonation, it is necessary for the dispenser to
be level, front to back and side to side.
D. Position the pump deck under the counter within close proximity to the dispenser. The pump
deck must be on a level surface and have adequate electrical utilities available.
1.7 CONNECTION OF THE EQUIPMENT
A. Position the CO
2 gas tank in the desired location. Assemble the high pressure regulator to the
CO2 gas tank and run the jumper line to the low pressure regulator.
B. Attach the CO2 gas line to the carbonator by attaching the line from the high pressure regulator
to the CO2 inlet. The setting of the high pressure CO2 gas regulator should be 75 PSI.
Do not turn on CO2at this time.
WARNING!
C. Position the syrup pumps in the desired location. Attach the CO
2 gas lines leading from the low
pressure regulator to these pumps.
D. Connect the syrup lines from the pumps to the appropriate inlets at the front of the unit. The
syrup inlets are identified at the bottom of the unit.
E. Connect the water inlet line to the pump. Complete the water line connection between the pump
and the water inlet to the carbonator at the bottom of the dispenser.
F. Provide a suitable drain in the plumbing system and attach the 3/4 inch (1.90 cm) diameter
schedule 40 PVC drains to it. The drip pan drainage outlet is located at the right rear of the unit.
The ice water drainage outlet is located at the right front of the unit.
G. Be sure to place the ice trap in the drain outlet inside the ice bin before filling with ice. This
device holds the ice away from the drain outlet, allowing the ice water to drain properly.
H. Plug in the transformer box to a standard 20 AMP, 110 VAC, single phase outlet. The unit will
internally convert the 110 VAC to 24 VAC.
1.8 START UP
A. After all connections to water, CO
2 gas, electrical power, and syrup pumps are made, check for
leaks.
B. Be sure the Bag-In-Box contains syrup.
Do not operate the carbonator pump deck with the water supply turned off.
WARNING!
C. Turn on water. Open the pressure relief valve on the carbonator tank by flipping up the valve cap
lever, and hold it open until water flows from the relief valve. Close (flip down) the relief valve
and turn on the CO
2 gas.
D. To fill all lines with water, cycle the carbonator several times by operating the dispensing valves.
1. Ensure a good flow of plain water is established from each valve.
2. Turn on CO
at source and ensure that the HP regulator is set at 75 PSIG.

3. Operate valves until unit gases out.
4. Plug in carbonator pump motor. Pump Deck will automatically start.
5
P.N. 28-0720/05
5. Activate carbonated water valves so that the carbonator pump cycles several times and a
good flow of carbonated water is established.
6. A low pressure gas regulator controls the flow of syrup to each dispensing valve. Connect
BIB connectors to BIB’s. Set LP regulator to 65 PSIG. Activate all valves to purge air from
the syrup lines.
NOTE: The unit will cycle on for 5.5 seconds, shut down, and immmediately start again and run
for additional 5.5 second intervals until the water level reaches the probe.
E. The dispenser bin should now be filled with ice cubes one inch below the level of the door
opening.
1.9 ADJUSTING WATER FLOW
A. The water flow can be adjusted to either 1.25 ounces/second (37 ml/sec) or 2.5 ounces/second
(74 ml/sec) on all dispensing valves, using the following procedure.
NOTE: The unit should have ice on the cold plate for a least one hour before you attempt to brix the
o
valves. The drink temperature should be no higher than 40
F (4.4oC) when the ratio is set. This
is done after the unit has ice in the ice bin.
C. Slide the ID panel up until the flow controls are exposed (see below).
D. Remove the nozzle by twisting counterclockwise and pulling down.
