Installation
Water Inlet Connection:
The National Sanitation Foundation requires the following for an NSF approved water hook-up:
1. A quick disconnect water connection or enough coiled tubing so that the machine can be moved for cleaning
underneath.
2. An approved backflow prevention device, such as a double check valve to be installed between the machine and
water supply. A 1/4" male flare adapter is provided (packed inside drain tray) to be attached by installer to the
back of the machine for hook-up to water supply. On units plumbed to permanent water line, installation of a water
filter/softener system is recommended to prevent lime and scale build up in the machine. On units pumping from a
remote water container, filtered water is recommended to prevent lime and scale buildup in the machine.
3. Water pipe connections and fixtures directly connected to potable water supply shall be sized, installed, and
maintained in accordance with Federal, State, and Local codes.
Start-up Procedure for Standard Units:
(Refer to serial tag to verify model number of your machine)
1. Install drain tray in front of machine. Connect the 1/4" male flare fitting (packed in drain tray) to the inlet valve on the
back of the machine.
2. Flush the water line to purge any debris from the supply line.
3. Connect a 1/4" water line to the 1/4" male flare connection and turn the water supply on.
Minimum water pressure to the machine: 20 psi
Maximum water pressure to the machine: 120 psi
4. Plug the power cord into a proper electrical outlet.
5. Turn the power switch to the “ON” position and allow the water tank to fill. The machine will make a subtle hissing
sound when this occurs. Allow 3-4 minutes for fill time depending on inlet water pressure.
6. After the water tank has filled, allow 30-45 minutes for the water to reach operating temperature depending on
wattage and tank size. (Green ready light will illuminate when tank is up to preset temperature).
7. Remove the powder hoppers and fill with desired powder product. IMPORTANT: Check to make sure that the auger
inside the hopper is correctly installed prior to filling (see figure F on page 8 for auger installation). Reinstall powder
hoppers. Make sure hopper elbows are down.
8. Peel protective film off photo merchandiser cover.
Note: If water supply is allowed to run dry, watchdog timer circuit may disable fill circuit. Ensure adequate
water supply for machine then reset machine by turning power switch off 1 second then ON.
