Connect Concentrate And Water Lines; Adjust Water-To-Concentrate Ratio - Cornelius Impulse Non-Carbonated Post-Mix Beverage Dispenser Installation And Operation Manual

Non-Carbonated Impulse Installation & Operations Manual
NOTE: Make sure that the electrical power circuit breaker is switched off or the fuse removed.
Before connecting electrical power to the unit, refer to nameplate to verify the power require-
ments.
A. Remove the following:
• front merchandiser by removing two screws on the top and lifting up
• key switch wires
• hood by removing two screws on the top and lifting up and forward.
B. Remove second valve from the left to facilitate routing of the new cord.
C. First route the new cord up behind the valve panel and through the cutout in the pump deck. Use
the already attached wire tie/fastener on the deck to secure the cord.
D. Connect cord to the receptacle on the refrigeration deck.
E. Turn the circuit breaker on and then the units power switch. Check to see that the agitator motor
has started. After about three minutes the compressor should start. If the agitator or compressor
do not start call Technical Services.

Connect Concentrate and Water Lines

1. Route concentrate and plain water lines from the back side of the unit and under the unit to the
front. Connect them to the appropriate inlet connections.
NOTE: If water supply pressure to the unit is less than 40 psi, a water pressure booster is
required. If water supply pressure to the unit is more than 50 psi, a water pressure regulator must
be installed in the supply line.
NOTE: A water shutoff valve and water filter in the water supply line are recommended.
2. Make the connection behind the splash panel to the marked 3/8 water tubes.
3. Connect optional drip tray drain hose (if used). Be sure the knock-out in the drip pan has been
removed if drain hose is used.
4. Bleed each valve into a bucket until water comes out.
5. Be sure that all concentrate sources are connected and on. Bleed each valve into a bucket until
concentrate comes out.
6. Reinstall drip tray and position water bath overflow hose in drip tray indent.
7. Check the system for gas leaks by pressurizing the system and then turning off the cylinder valve.
Wait a couple of minutes and check the cylinder gauge to see if the pressure has dropped.
8. Check the system for water and concentrate leaks.

Adjust Water-To-Concentrate Ratio

1. Remove valve front cover and install concentrate diversion assembly in place of nozzle.

2. Adjust carbonated water flow to the desired rate (such as 2.50 oz./sec.).
Turn the adjuster 1/4 of a turn at a time and recheck the flow.
To increase flow turn clockwise.
3. Adjust the concentrate-to-water ratio of each valve using the concentrate adjuster on the left side of
each valve. Hold cup under valve and dispense beverage for a specific time (such as 4 seconds).
