INSTALLATION
MOUNTING
Pump should be located within 10 ft. (3.0 m) of bag-in-
box and must be mounted with ports facing down. May
be mounted above or below bag. Fasten mounting
brackets securely to rack or mounting board. The pump
is sanitized at factory and needs no further sanitizing
before connection to the product supply.
HOSE CONNECTIONS
Product “IN”, use 3/8” (7.9 mm) I.D. x 1/8” (3.1 mm) wall
vinyl or Tygon hose, food grade or equivalent. Secure
with OETIKER 17.0 706R clamp or worm gear clamp
with 360° uniform clamping band. Avoid sharp bends
that could restrict flow or cause hose to collapse under
vacuum. Connect to bag-in-box connector (or transfer
valve if used) and clamp both ends.
Product “OUT”, use reinforced 1/2” (12.7 mm), 3/8” (9.5
mm) or 1/4” (6.3 mm) I.D. hose for discharge. Connect to
product “OUT” port and dispensing head product
(syrup) connection and clamp both ends securely.
Gas “IN”, make sure CO
2
regulator is set at zero. Use
reinforced 1/4” (6.3 mm) hose, connect gas “IN” to gas
supply fitting on regulator. If pumps are installed in an
enclosed area such as a basement, it is recommended
to connect a hose to the gas discharge port and vent
CO

to atmosphere.
OPERATION
To start operation, regulate gas pressure to desired
setting. For most installations, 65 PSI (4.5 BAR) will be
adequate. Open dispensing valve to purge air from
system. Pump will now operate automatically by starting
and stopping on demand, as beverages are served and
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 (5.6 BAR) gas pressure.
The Flojet Model N5000 has an auto shutoff valve which
stops the pump by shutting off the gas supply when the
bag is empty and high vacuum builds up in the inlet line.
The control will automatically restart the pump when a
new bag is connected and vacuum in the inlet line has
returned to normal.
