INSTALLATION GUIDELINES
•
The outlet port/fitting of the pump is mounted vertical, up.
•
The pump should be mounted above the B-I-B or at least at the same level. Pumps placed lower than
the B-I-B’s will increase the ability to entrap air in the B-I-B.
•

vertical lift.
b)

) products (over 500 cP); may require

tubing with minimal
vertical lift. In some instances no vertical lift can be achieved, the pump may need to be placed
within one foot from the B-I-B, and slightly above the center of the B-I-B.
NOTE:
High inlet vacuum and/or restrictions can evacuate air suspended in some concentrates causing
low brix or premature operation of the vacuum shut-off.
•
Use high pressure, NSF listed, braided tubing from the pump
outlet
to the dispenser equipment. Use

tubing as necessary.
•
Tie-wrap all tubing securely to prevent kinks or sags that inhibit performance or cause damage to the
pump fittings.
•
Use

, high pressure braided tubing from the secondary CO

/air regulator to the pump.
NOTE
:
NEVER
connect a transfer tank "system" in series with a B-I-B system. Concentrate/contaminants in
old components may work their way through the air supply causing premature failure of the gas
pump. The gas used to drive the pump
MUST
be clean and contain no contaminants (syrup, oil,
rust, water, etc.). Air compressors may be used with proper particle filters and moisture
separators. Air storage tanks should be drained weekly. Pumps subjected to contaminated air
are not
covered by warranty.
CAUTION
: Pumps driven with CO
2
are to be operated in well-ventilated areas. If used in a confined
area (basement, closet, cooler box, etc.), exhaust fans capable of changing the room air on
a continuous basis should be used.
START-UP PROCEDURE
1.
Confirm that all tubing connections are properly clamped, fittings are locked, and tubing is not kinked.
2.
Connect the bag connector onto the B-I-B fittment. Open the dispenser valve (syrup side)
3.
Adjust gas regulator to about 20 psi.
[1.4 bar]
allowing the pump to stroke slowly. Once the pump is
primed the regulator can be adjusted up. With high viscosity (thick) products (over 500 cP), the pump
should be primed with a
minimum
of gas pressure. This prevents the shut-off feature from
interupting pump operation due to high inlet vacuum during priming.
4.
Continue to operate the dispenser valve until
all
the air trapped within the tubing has been purged.
5.
Once the air has been purged, adjust the CO
2
regulator to the pressure necessary to maintain the
desired brix. The most efficient gas usage occurs at 40 psi.
[2.8 bar]
.
Maximum
gas pressure to the
pump is 70 psi.
[4.8 bar]
; minimum 20 psi.
[1.4 bar]
.
NOTE:
To prevent air from entering the system always leave the bag connector connected to the empty
B-I-B until a new B-I-B can be installed. Air entered into the system, via air in the bags or
vacuum leaks, may cause brix fluctuation, foaming, spitting, non-operation of the vacuum shut-
off, or the pump to run while the dispenser is closed. Symptoms of this kind can lead to a
misdiagnosis of the pump as the problem.
