Filling Cambros or other large containers:

The dispenser is designed primarily for cups or other small containers that will fit under the dispense tips. However, it may be used to fill larger containers (up to 5 Gal) by use of an extension hose on the dispense tip. Removing the Flow Restrictors will increase the dispenser flow rate to 2.5 Oz/sec. (74 mL/sec.) and reduce the time to fill larger containers, (see Setting Dispenser Flow Rate.)

Care must be taken to insure that the mixed product flows freely from the dispense tip into the container.

1.Use a 5/8” I.D. or larger, NSF (National Sanitation Foundation) approved hose.

2.Use as short a hose as possible with no loops, bends or kinks in it.

3.Insure that the outlet of the hose is below the dispense tip and that the mixed product flows freely into the container

A properly sized and positioned hose will not run full or back up into the dispense tip. Failure to follow these directions can alter the mix ratio and/or cause flooding of the vent tube.

NOTE: The temperature of the product being dispensed will start to drop after ~2 gal. continuous draw. Recovery time will be dependent on the temperature of the supply water and the voltage at which the heater coil is being operated.
