Dema's drum mount dispensers mount to any 2 1/2” bung opening to dispense chemical solution directly from the drum or tote at the correct dilution. The (162.3) Drum Mount Proportioner w/ Metering Tip Kit dispenses at five (5) GPM with a maximum induction or dilution ratio of 5-1, adjusted with the provided metering tips. 

Upon completion of the installation of the Fusion Pro; dispensing of diluted chemical can be performed in several ways depending on the dispenser configuration. To operate the dispenser, follow the steps below. For bottle fill dispensing, place the chemical outlet tube into the container to be filled. Use the 1 GPM proportioner for this type of dispensing. Press the button to start the dispenser. Release the button once the container has filled. For bucket fill dispensing, place the outlet tubing into the bucket. Follow step 2. If you would like to use the locking activation feature, for dispensing to larger containers, see step 10 of the Installation and Servicing section, on page 5 of this manual. To activate the locking feature, press the 4 GPM button, and then twist it clockwise. This will engage the locking feature, and it will continue to dispense until you turn the button counterclockwise and release the button.
