1.9 CONNECTING PYTHON TO TOWER (SEE FIGURE 2)
A. Route opposite end of python to tower. Determine length required, and cut if necessary.
Be sure to allow additional length as required for servicing.
B. Slit python insulation back 12 inches (30 cm) from end and roll insulation back to expose
individual tubes. Cut tubing to length as shown in Figure 2.
C. All Delta towers have the plain water feature, factory installed. If plain water is not wanted, splice
a stainless steel, reducing, barbed hose tee (PN 01-0527) in the 3/8 inch soda line. Use a
separate 1/4 inch tube to complete the connection from the barbed tee to the tower manifold.
D. Connect each of the plastic lines from the python to the barbed fittings on each of the stainless
steel syrup, soda, and plain water lines on the tower manifold. Start with connections at the back
of the tower manifold first. Secure with Oetiker clamps.
NOTE:
Do not insulate connections at this time. Leave all connects exposed for inspection for
leaks. Refer to Section 1.18 to complete insulation.
1.10 CONNECTING 24VAC POWER SUPPLY TO TOWER NOTE
The remote recirculating unit is designed to supply 24VAC power to the valves on the dispensing
tower. An extension cord of 25 feet (8 meters) is provided for this purpose in the tower. A separate
power supply must be used if the tower is located more than 25 feet (8 meters) from the remote
recirculating unit.
A. Remove cover from electrical control box on remote recirculating unit, and route white and black
wires (bundled) through the opening in side of control box. Replace cover.
B. Connect extension cord to white and black wires.
C. Route extension cord with python to tower.
D. Connect white wire to terminal on key lock switch, and black wire to loose black wire in tower.
E. A separate power cord is provided for the lighted merchandiser.
1.11 CONNECTING TO WATER SUPPLY
A. Using tubing and fittings from installation kit, connect tubing assembly to water source.
DO NOT
CONNECT TO DISPENSER AT THIS TIME.
B. Flush water supply line thoroughly.
C.
IF THE WATER SOURCE IS ABOVE 50 PSIG (3.52 KG/CM2), CUT TUBING ASSEMBLY AND
INSTALL WATER REGULATOR KIT (PN 18-0253/01) AS SHOWN IN KIT INSTRUCTION
SHEET.
NOTE:
The water supply must be protected by means of an air gap, a backflow prevention device
(located upstream of the CO2 injection system) or another approved method to comply with NSF
standards. A backflow prevention device must comply with ASSE and local standards. It is the re-
sponsibility of the installer to ensure compliance.
D. Route tubing through hole in counter and through opening behind splash plate and connect to
carbonator pump, using a flare seal washer (PN
). Use a back-up wrench to prevent
damage to carbonator pump.
E. Leave 12 inches (30 cm) of extra tubing length below the counter for servicing and moving the
dispenser.
F. Turn on water supply and check for leaks.
G. Using test gauge assembly (PN 22-0138), set regulator at 50 PSIG (3.52 kg/cm2).

!
WARNING
USE A SHARP KNIFE, RAZOR BLADE, OR TUBE CUTTER TO CUT TUBING.
TUBING CUT WITH A SAW WILL RESULT IN PLASTIC SHAVINGS, WHICH WILL PLUG THE
FLOW CONTROLS IN THE DISPENSING VALVE.
!
WARNING
IF WATER SOURCE EXCEEDS 50 PSIG (3.52 KG/CM2), A WATER REGULATOR
KIT MUST BE USED TO LIMIT WATER PRESSURE TO 50 PSIG (3.52 KG/CM2). FAILURE TO
USE REGULATOR WILL RESULT IN IMPROPER PERFORMANCE OF DISPENSER.
