Operated Bag-in-Box Pump
INSTALLATION MOUNTING
Pump should be located within 10 ft. (3.0 m) of bag-in­box 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 CO2regulator 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 CO2to 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.

The above diagram shows a “typical bag-in-box installation” with a single bag connection and multiple bag connection with the FLOJET Transfer Valve assembly.
The FLOJET Part No. 1510-000, or 1520-000, or 1521-000 CO2shutoff disconnect (options) is recommended to simplify pump servicing. When the gas “IN” port is removed, the CO2is shut off at the port fitting. This eliminates the need to shut off the gas supply to other systems in use. Gas pressure is restored when the port is again plugged into the pump.
The FLOJET Part No. 1500-030, or 1500-031 transfer valve is recom­mended for automatic unattended changeover from empty to full bag.
FLOJET Part No. 2095-502 automatic syrup sold out switch. Automatically shuts off electric dispensing valve when syrup is sold out and turns on “Sold-Out” light.
TROUBLE SHOOTING
