Installation Operation & Service Instructions
Flojet N5000 Series

Operated Beverage Pump
Bracket Assembly
A front installation requires the following hardware, four
#8 Phillips pan head self-drilling sheet metal screws to
mount on “Area A”, which in turn is mounted on the
riser/spacer of the bag-in-box rack (see fig. #1 & #6). On
a side installation, the same hardware is used, but the
area affected is “Area B” (see fig. #8). For wall
installation, four anchor bolts are provided. All pumps/
transfer valves are identified left to right as follows: #3,
#2, #1. On a standard three shelf bag-in-box rack, #3
pump services the top shelf, #2 pump services the
middle shelf and #1 pump services the bottom shelf.
This also applies to the transfer valves. For quick
installations, please note all pumps have the CO2inlet
line manifold. Only one CO2line is needed from CO
2
source to pump bracket assembly. A 3/8 inch (9.5 mm)
product out (quick-disconnect fitting) stainless steel
barb port is provided with every pump.
Pump bracket assemblies/transfer valve assemblies are
capable of readily accepting installation of Flojet and
Shurflo products. (See fig. #7 for proper removal of
pumps.) Pump bracket assemblies/transfer valve
assemblies adapt to the Red Line bag-in-box rack. (See
fig. #6 for routing of hose and tube hangers.)
All suction line lengths from pump inlet to box connector must not exceed 10 feet (3 m). Transfer valve is
located between pump and box and now includes 15
feet (4.6 m) of hose for special applications. Pumps must
be above bottom of corresponding box when installed
on bag-in-box rack. When securing bag-in-box rack to
wall, you must allow a nominal one inch (25.4 mm)
clearance between the wall and the rear legs of the rack.
Pump Assemblies With Transfer Valves
Hose length should be no greater that five feet (1.5 mm)
vertical distance between center line of pump and
bottom of box it is pumping from.
Pump Assemblies Without Transfer Valves
Installation on bag-in-box racks must be provided for no
greater than ten feet (3 m) vertical distance between
center line of pump and bottom of box it is pumping
from.
Mounting Hardware For Installation Of Pump &
Transfer Valve Assemblies To Bag-In-Box Rack
1. Quantity of four #8 Phillips pan head self-drilling
sheet metal screws.
2. Minimum of two tube hangers per suction hose to
fasten hose to bag-in-box rack.
3. Quantity of four #8 Phillips pan head self-tapping
screws for use with anchor bolts for wall mounting.
4. Quantity of four anchor wall mounting anchors.
5. All Oetiker clamps must be stainless steel and of
step-less design.
6. Quantity of one plastic tie wrap provided for product
out hose.

To start operation, regulate gas pressure to desired
setting. For most installations, 65 PSI (4.4 bar) will be
adequate. Open dispensing valve to purge air from system. Pump will now operate automatically by starting
and stropping on demand, as beverages are served
while maintaining constant pressure at the dispensing
valve. Product flow and pressure can be adjusted by
increasing or decreasing gas pressure to accommodate
varying product viscosities, length of lines or other
installation conditions. Caution: Do not exceed 80 PSI
(5.5 bar) gas pressure or manufacturer’s maximum
recommended pressure. The Flojet Model N5000 has
an automatic vacuum shutoff valve which stops the
pump by shutting off the gas supply to the pump when
the bag is empty and high vacuum builds up in the inlet
syrup line. The control will automatically restart the
pump when a new bag is connected and vacuum in the
inlet syrup line has returned to normal.

Proper Handling Of
Retainer Bar Assembly
Caution! Pull retainer bar assembly from
two positions on either side of pump with your
fingers. Do Not use a screw driver for removal of
the pump to maintain future retainer bar assembly
tension. Note: The CO2manifold would change if a
Shurflo pump is installed.
