INSTALLATION GUIDELINES
•
Mount the pump so the CO
2
inlet and liquid outlet fittings are point down.
NOTE:
The right bracket keyhole slot is
not
accessible with a screwdriver. The
screw
must
be installed first allowing clearance to slip the keyhole slot over
screwhead. Tighten the left mounting screw securely.
•
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.
•
The
MAXIMUM
length of
INLET
tubing is
3
M
,
with
NO MORE
than a
1.5
M
vertical lift.
Use clear, 10mm I.D., vacuum rated heavy wall (3 mm), food grade tubing from the B-I-B
to the pump inlet.
•
If necessary to connect B-I-B’s together, plumb (Tee) B-I-B's
side-by-side
horizontally, rather than one on top of the other, vertically.
•
OUTLET
tubing from the pump to the dispenser should be 10mm I.D.. high
pressure, food grade, braided tubing. Always cut outlet tubing longer than
necessary to provide a "service loop" so the B-I-B rack can be moved for cleaning
or service.
•
Tie-wrap all tubing securely to prevent kinks or sags that inhibit performance or
cause damage to the pump fittings.
•
Use only
new
6mm I.D., CO
2
approved high pressure tubing between low pressure
regulator and the pump.
NOTE:
NEVER
connect a transfer tank "system" in series with a B-I-B system.
Syrup contaminants in old components may work their way through the air
supply causing premature failure to 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.), CO
2
exhaust should be vented to the outside.
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/inlet tube onto the bag fitting. Open the dispenser
valve (syrup side).
3.
Adjust gas regulator to about 1.4 bar, allowing the pump to stroke slowly. Once
the pump is primed the regulator can be adjusted up.
4.
Continue dispensing syrup 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 brix. The most efficient gas usage occurs at 2.8 bar.
Maximum
gas pressure to the pump is 5.9 bar; minimum is 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.
PUMP SANITIZING / WINTERIZING
The SHURflo pump is only one piece of a beverage dispensing system. Therefore,
frequent sanitization of the pump and
ALL
equipment in the system is required.
Sanitization is dependent on the syrup or beverage type and its manufacturer’s
requirements.
Factors which also affect the frequency of this procedure are
temperature, facility conditions, installation, and equipment. Consult other equipment
manufacturer's instructions for their sanitizing requirements. Refer to SHURflo
Service Bulletin
#
1025 for the N.S.F. listed sanitizing procedure for the SHURflo
pump
(only)
.
CAUTION:
Never use pressurized tanks to sanitize or purge the pump of fluid (operating
or not). Applying pressure to the pump inlet could damage internal
components.
If the pump is subjected to temperatures of 0ºC or lower, the system must be drained of
all liquid to prevent damage due to freezing. It is suggested that when taking a pump
out of service, the pump and lines, etc. must be sanitized and purged of all fluid. Refer
to the equipment manufacturer's recommendation on purging lines and dispenser
equipment. Refer to SHURflo Service Bulletin
#
1025 for complete winterizing
procedure.
