CAUTION - The dispenser must be disconnected from the power source throughout the initial set-up, except 

when specified in the instructions.

1.  Turn-on the water supply and connect the dispenser to the power source.

2.  Water will automatically flow into the tank to the proper level and then shut-off.  This will take less than five 

minutes. 

3.  When the tank is full of water, open the front door and place the heater switch in the “ON” (lower) position.  

A tank full of cold water will take approximately eighty minutes (IMIX-5S) or forty-five minutes (IMIX-3S) 

for the water to heat on 120 volt versions or forty minutes (IMIX-5S) or twenty-five minutes (IMIX-3S) for 

120/208 volt versions and 120/240 volt versions. 

During this waiting period, complete these dispenser set-up steps:

a.  Place the drip tray in front of the dispenser.  Set the drip tray cover in place.

b.  Place a set of keyholes in the cup locator plate over the screws beneath the hopper access door and push 

down gently.

c.  Fill the hoppers with the dry product to be dispensed.

1.  Flush the water line and securely attach it to the flare fitting on the bottom of the dispenser.

2.  Turn-on the water supply.
NOTE - Water pipe connections and fixtures directly connected to a potable water supply shall be sized, installed 

and maintained in accordance with federal, state and local codes.

This dispenser must be connected to a COLD WATER system with operating pressure between 20 and 100 psi 

(138 and 690 kPa). This water source must be capable of producing a minimum flow rate of 4.5 fl. oz. (133.1 

ml) per second.  A shut-off valve should be installed in the line before the dispenser.  Install a regulator in the 

line when pressure is greater than 100 psi (690 kPa) to reduce it to 50 psi (345 kPa).  The water inlet fitting is 
.38" (9.52 mm) flare.
NOTE - At least 18 inches (457 mm) of an FDA approved flexible beverage tubing, such as reinforced braided 

polyethylene or silicone, before the dispenser will facilitate movement to clean the countertop.  It can be purchased 

direct from Bunn-O-Matic (part number 32759.10--[See Illustrated Parts Catalog for complete part number]).  

Bunn-O-Matic does not recommend the use of a saddle valve to install the dispenser.  The size and shape of the 

hole made in the supply line by this type of device may restrict water flow.

Tank temperatures have been preset at the factory to 180°F (82°C). Bunn recommends that to provide the 

best quality beverage, the installer adjust the tank temperature to the powder product manufacturer’s recom-

mended temperature for the hot powder product being used.

The system automatically maintains the hot water tank’s level by energizing the refill solenoid when the water 

level drops below the liquid level probe. If the system has not successfully refilled in 15 minutes, a refill error 

occurs. When a refill error occurs, the refill solenoid is de-energized and the left rinse L.E.D. will flash  about 

once every 5 seconds. Once the cause of the refill error has been investigated (see the troubleshooting guide in 

the Operating and Service Manual) and cured, the system can be reset by placing the Rinse/Run switch in the 

programming (center) position, momentarily.
