when moving the unit.
Review all information here first, then perform the following steps to place the Spire unit in position on the counter:
WARNING
!
CAUTION
!
1. Locate the indoor placement of the dispenser. The dispenser can be placed directly on the counter top or it
can be placed on the counter top using the optional Anti-Tip Kit (sold separately).
Counter Mounting
For direct mounting of the dispenser to a level counter top (without legs), openings must be cut into the
counter. To do this, locate the desired position for the unit, then mark openings on the counter using
dimensions provided in Figure 2.
After direct counter top mounting, the unit must be sealed to the counter. Apply a continuous bead of NSF
International (NSF) silicone sealant (Dow 732 or equal) approximately 1/4-inch around the outside of the
unit. All excess sealant must be wiped away immediately.
Counter Mounting with Optional Anti-Tip Kit
Follow kit instructions for proper installation.
WARNING
!
Failure to install the Anti-Tip Kit properly could result in a hazardous situation which, if not avoided, could
result in serious injury, death, or equipment damage.
NOTE: The dispenser MUST be place in a horizontal, level position and product and supply lines must be
flexible enough to permit shifting the position of the dispenser (when cleaning the area beneath the dis-
penser, etc...).
2. Move the fountain lift with the unit to the front edge of the counter
where it will be installed.
Figure 10
3. Carefully jack up the fountain lift so that the bottom of the unit is

REPLACING THE ENCLAVE
Read all steps first, then, perform the following steps to replace the Enclave. Note that you should not replace the
Enclave until after all supply lines and drain lines are established and no leaks are detected.
1. Before replacing the Enclave, make sure all lines and drains are connected properly and no leaks are
detected.
2. To replace the Enclave, the drain pan must be in
position. Place the drain pan into the unit as
shown in Figure 17.
3. With the drain pan in place, tilt the top of the
Enclave unit toward the inside of the unit and
position the left and right sides of the Enclave
on top of the left and right sides of the drain pan,
respectively.
4. With each Enclave tab released from a tab hold-
ers, guide the Enclave forward and out of the
unit. Place it in a safe place.
Result: The Enclave is removed from the unit
and the service lines are exposed to support
installation and service activities.

INSTALLING WATER, CO2AND SYRUP LINES
Once the unit is located in its final position on the counter, the unit must be plumbed by connecting the supply lines
(water, CO2and syrup lines). Perform the procedure below to plumb the unit.
1. Locate the water and syrup input tubes.
The lines are marked as follows:
Note: If lines are to be cut, mark the line numbers above
the cut with a marker. Make sure that syrup lines and fla-
vor lines are not mixed.
CAUTION
!
IMPORTANT
!
2. Connect the beverage system product tubes to the python coming from the back room package, depending
on the unit being installed.
3. Turn the carbonator pump power switch to the OFF position. The power switch for the carbonator pump is
usually located on an electrical junction box as part of the carbonator pump deck assembly.
4. Connect the inlet water line to the carbonator pump and
connect the outlet port on the carbonator pump to the
Spire unit using 3/8” (0.95 cm) food-grade tubing.
5. Route the power cord used for providing power to the carbonator pump (located behind the Enclave of the
Spire unit) to the carbonator pump deck assembly. The Spire unit provides power to the carbonator pump.
6. With the carbonator pump power switch in the OFF position, connect the power cord from the Spire unit to
the power junction box supplying power to the carbonator pump. Leave the power switch OFF.
•S1 through S14 /F1-F6 for syrups
•CW for carbonated water
•W for Plain water
•F1 through F6 for flavor shot lines
Figure 19
•Do not install water pressure regulator on the plain water inlet between the back room package and the unit
•Check the minimum flow rate and the maximum pressure of the plain water inlet supply line. Minimum flow
rate must be at least 125 Gal/Hr (0.47 cubic m/hr). If flow rate is less than 125 Gal/Hr (0.47 cubic m/hr),
starving of the carbonator water pump occurs. Starving causes the carbonator water pump to overheat.
•The maximum water pressure can be no more than 65 psi (0.45 MPa), etc.]. If necessary, add a 65 psi
regulator to the soda water line. Water over-pressure (higher than CO2) can cause carbonator flooding,
malfunction, and leakage through the carbonator relief valve. Do not add a regulator to the still water supply.
•Incoming plain water inlet supply line pressure to the pump MUST remain a minimum of 10 psi (0.07 MPa)
BELOW the carbonated CO2operating pressure. [Example: Carbonator CO2operating pressure is 75 psi
(0.52 MPa).
•Make sure the unit is not plugged into the AC power source.
•If water exceeds maximum pressure specifications, a water pressure regulator kit must be installed in the
plain water inlet supply line.

INSTALLING THE DRAIN
After installing the syrup, water and CO2lines, the drain lines must be installed.
Perform the following steps to install the drain line:
1. Pull the drain tube stub from the storage space in the bottom of the unit and route it through the cut-out in the
counter.
2. Connect the drain tube stub from the unit to the drain tube on the
drain pan.
3. Figure 22 shows the drain tube on the drain pan.
NOTE: After the ice bin has been sanitized, and after the supply lines and drain line is installed, it is
recommended that the ice bin be filled with ice. This is because the cold plate must be chilled for a
minimum of 30 minutes before brixing is performed. See “Filling the Ice Bin (Manual)” on page 19.
Note: Route the drain tube to an open drain with the end of the
tube above the “flood” level of the drain. Use the tubing, fittings,
clamps, and insulation provided with the dispenser to assemble
the drain. The completed drain line must pitch continuously down-
ward and contain no “traps” or improper drainage will result.
Figure 21
IMPORTANT: Make sure the drain tube is fully insulated to pre-
vent condensation and connect the drain tube to the drain pan
with a hose clamp but DO NOT over-tighten the clamp. Tighten to
maximum of approximately 16 in/lbs torque.

FILLING THE ICE BIN (MANUAL)
For an Ice Maker equipped unit, refer to the ice maker manufacturer's manual to begin filling the ice hopper with ice.
The dispenser cannot be used with crushed or flaked ice. Use of bagged ice which has frozen into
large chunks can void warranty. The dispenser agitator is not designed to be an ice crusher. Use of
large chunks of ice which jam up inside the bin will cause failure of the agitator motor and damage to
the bin. If bagged ice is used, it must be carefully and completely broken into small, cube-sized pieces
and left to “temper” or warm up for a minimum of 20 minutes at room temperature before loading it into
the ice bin.
1. Open the display door.
2. Remove the cover from the ice bin. See Figure 23.
3. Fill the bin with ice. (255 lb. MAX).
!
Important: Do not over-fill the ice bin.
4. Replace the ice bin cover. See Figure 23.
5. Close the door. See Figure 23.
6. After loading ice into the bin, wait 30 minutes to allow the cold plate to chill the syrups to the proper operat-
ing temperature.
Perform the following steps to fill the ice bin.
START SYRUP FLOW
Start the syrup pumps and adjust them to the following pressures:
•Sugar Syrups: 65-75 psi (depending on syrup viscosity)
•Diet Syrups: 45 psi (depending on syrup viscosity)
•Flavor Shots: 35 psi

INITIAL SETUP
Plug the cord into the carb deck, and then plug the carb deck into the protected AC wall outlet.
WATER SUPPLY AND CO2REGULATOR SETUP
Perform the following steps to setup the water supply and the CO2 supplied to the unit.
CAUTION
!
•Before connecting the CO2regulator assembly to a CO2cylinder, turn the regulator
adjusting screw to the left (counterclockwise) until all tension is relieved from the
adjusting screw spring.
•Never operate the carbonator pump with the water inlet supply line shutoff (valve
closed). “Dry running” the water pump will burn out the pump. A pump damaged in this
manner is not covered by warranty.
1. If necessary, remove the Enclave.
To do this, see “Removing the Enclave” on
page 15.
Figure 24
2. Turn on the main water supply valve to flood the unit
3. To displace the air from the carbonator tank,
open the carbonator tank relief valve until water
flows into the drip tray.
On the Spire 4.1 unit, the carbonator tank relief
valve is located to the right of the agitator motor
on the far right side of the unit. To open the
valve, pull on the valve ring.
Once water flows into the drip tray and air in the
tank is displaced, push on the relief valve to
close the valve. Figure 25
4. Locate the CO2supply and turn (counterclock-
wise) the CO2cylinder valve slightly-open to
allow the lines to slowly fill with CO2gas, then
gradually turn the valve open to fully to back-
seat the valve.
Note: Back-seating the valve prevents leakage
around the valve shaft). The carbonator CO2
regulator is fixed at a normal 75 psi.
