NOTE:
Bag connectors should
never
be left unconnected from bags due to health concerns. The
correct procedure for B-I-B replacement is that the bag connectors
must
be left connected until a new
(full) box can be installed. Bag connectors that are not connected to a bag may be the cause of a
vacuum leak and improper pump operation.
INSTALLATION GUIDELINES
•
The outlet port of the pump is mounted vertical/ up.
•
The pump is normally to be mounted at the same level or slightly higher than the B-I-B.
•
Use 1/2" or 3/8" I.D. [13 or 9.5mm] heavy wall (1/8" [3 mm]) clear, NSF listed vacuum tubing from the B-
I-B to the pump
inlet
.
a)
For low viscosity (
thin
) products (40 CPS), the
maximum
length of inlet tubing is 5 ft. [1.5M] with
NO
MORE
than a 3 ft. [.7M] vertical rise.
b)
High viscosity (
thick
) products (over 500 CP.); require 1/2 I.D. [13mm] inlet tubing with a
maximum
length of 1 ft. [.3M]. In some instances no vertical lift may be obtained, and the pump may need to be
placed at the same level as the B-I-B fittment.
NOTE:
Restrictions and/or high inlet vacuum can evacuate air suspended in some condiments
(degassing) or cause premature operation of the vacuum shut-off.
•
Use high pressure, NSF listed, braided tubing from the pump
outlet
to the dispenser equipment. Use
3/8" I.D. [9.5 mm] or 1/2" I.D. [13mm] tubing as necessary.
a)
For low viscosity (
thin
) products (40 CP.), the
maximum
recommended length of outlet tubing is 50
ft. [15M] with
NO MORE
than a 10 ft. [3M] vertical rise.
b)
High viscosity (thick) products (over 500 CP.), will require 1/2 I.D. [13mm] outlet tubing with a
maximum
length of 10 ft. [3M] with
NO MORE
than a 5 ft. [1.5M] vertical rise.
•
Tie-wrap all tubing securely to prevent kinks or sags that inhibit performance or cause damage to the
pump fittings.
•
Use new 1/4" [6mm], high pressure braided tubing from the secondary CO
2
/air regulator to the pump.
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.
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.
START-UP PROCEDURE
1.
Confirm that all tubing connections are properly clamped, fittings are tight, and tubing is not kinked.
2.
Connect the Q.D./inlet tube onto the bag fittment. Adjust gas regulator to about 30 psi.[1.4 bar]
allowing the pump to stroke slowly. With high viscosity (thick) products (over 500 CP.), the particulate
pump should be primed with a
minimum
gas pressure of 50 psi. [3.5 bar]. Operate the dispenser
valve to relieve trapped air within the tubing.
3.
Once the air has been purged, adjust the CO
2
regulator to achieve desired condiment delivery. Set the
regulator to the minimum pressure necessary to maintain the desired fluid delivery. The most efficient
gas usage occurs at 40 psi. [2.8 bar].
Maximum
(static) gas pressure to the pump is 70 psi.[4.7 bar],
minimum 20 psi.[1.4 bar].
