INSTALLATION

START UP PROCEDURE

WATER CONNECTION

The National Sanitation Foundation requires the following for an NSF approved water hook-up:

• A quick disconnect water connection or enough coiled tubing so that the machine can be moved for cleaning underneath.

• 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. Installation to a water filter system is recommended to prevent lime and scale build-up in the machine.

• Water pipe connections and fixtures directly connected to portable water supply shall be sized, installed and maintained in accordance with

federal, state and local codes.

• Flush the water line to purge any debris from the supply line.

Connect a 1/4” pressurized water line to the 1/4” male connection

(on rear of brewer) and turn the water supply on.

a) Minimum water pressure to the machine: 30 psi

b) Maximum water pressure to the machine: 80 psi

NOTE: Single head machines may be used without a pressurized water

supply. (See Pour-Over Mode section)

ELECTRICAL CONNECTION

NOTE: Wiring connections should be performed by a qualified technician.

(Refer to serial tag to verify model number of your machine)

•

Remove front panel.

• Connect electrical service through rear of machine to terminal block

(inside front panel) marked L1, N, and L2. (See Figures A and B)

• On dual volt units, flip voltage switch (inside front panel next to terminal

block) to 120V for 120 Volt service or 240V for 120/208, or

120/240 Volt service. (See Figures A, B and table below)

• Re-install front panel.

• Turn on (plug-in) electrical service to brewer.

• Water tank will fill after a 7-second delay. The machine will make a

hissing sound when this occurs. On single head models, allow

approximately 1.5 minutes for the brewer to fill. On two head models, allow approximately five minutes for the brewer to fill.

NOTE: If water supply is inadequate or not connected, display will read “P-O” after 4 minutes of fill time (Refer to Pour-Over Mode

section). If Fill Cycle times out and display reads “P-O” before tank is full, turn unit OFF then ON again to reset and continue filling.

• The tank will begin heating slightly before machine fills.

• Turn brewer on by pressing ON/OFF switch in front of machine. (Light will illuminate)

• The brewer settings can be adjusted through the front touch pad. (Refer to Adjustments section)

• The water will be hot and the brewer will be ready to brew when “READY” light illuminates.

• Set Brew volume. (Refer to Setting Brew Volume section)
