Start-Up Procedures for Pump Units (PIC 2P & PIC 3P only)
NOTE: Pump units are not designed to be plumbed to pressurized water source.
1. Place a five gallon water container within 3 feet vertically and 2 feet horizontally of the machine.
2. Drop the hose at the rear of the machine into the water container (The hose should extend to approximately
1" from the bottom of the water container.)
NOTE: Do not let the end of the hose touch the bottom of the container. Shorten the hose if necessary. If you
need a longer hose, remove the back access panel, unclamp existing hose, replace with longer hose and
replace clamp.
3. Proceed with fifth step under Start Up for Standard Units.
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 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 the drain tray) to be
attached by the installer to the back of the machine for hook-up to water supply.
4. Installation to a water filter system is required to prevent lime and scale build up in the machine.
5. 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
NOTE: NSF requires installation of 4” legs for PIC 2,3,4,5,6.
1. Install drip tray in front of machine.
2. Connect the 1/4" male flare fitting to the inlet valve on the back of the machine.
3. Flush the water line to purge any debris from the supply line.
4. Connect a 1/4" water line to the 1/4" male flare connection and turn the water supply on.
a. Minimum water pressure to the machine: 20 psi
b. Maximum water pressure to the machine: 100 psi
5. Plug the power cord into a proper electrical outlet.
6. 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 (5 minutes for PIC 5 or PIC 6) for fill time depending on
inlet water pressure.
7. After the water tank has filled, allow 15-45 minutes (45-60 minutes for PIC 5/6) for the water to reach
operating temperature. (Green ready light will illuminate when tank is up to preset temperature.)
8. Remove the powder hoppers, rotate the dispense elbow to the “up” position, and fill with desired powder
product. IMPORTANT: Check to make sure that the auger inside the hopper is correctly installed prior to
filling. Reinstall powder hoppers. Turn dispense elbow down toward the mixing funnel.
9. Peel protective film off photo merchandiser cover.
10. Install flavor decals as needed. (Place one on each hopper, and place the corresponding decal on the
dispense section of the front door of the unit)
NOTE: If water supply is allowed to run dry, watchdog timer circuit may disable fill circuit. If this occurs, ensure
adequate water supply for machine, then reset machine by turning power switch “OFF” for 1 second and then
turning the power switch back “ON”.
NOTE: Watchdog timer might engage on initial fill on PIC 5 and PIC 6.
