with a fused disconnect switch or a circuit breaker
near the brewer.
Important:
Means shall be provided to ensure all pole
disconnection from the supply. Such means shall be one
of the following: a supply cord fitted with plug, or a
switch that is directly connected to the supply terminals
and has a contact separation of at least 1/8” (3mm) in
each pole.
3. Attach the appropriately sized cord to the brewer
with a cord grip for the 3/4” conduit (1-1/8”
diameter) electric input opening. The cord may
enter through the rear or bottom on the left side
of the brewer. Use an oil resistant cord such as type
SO, SOO, SAO, STOO, SEO, SJO, SJOO, SJTO, SJTOO,
SJEO, HSO, HSOO, HSJO, or HSJOO. Alternatively,
flexible conduit and type THHN wires may be used.
Use only copper conductors.
4. All models except for cord provided models are
considered Field Wired. Standard connection is 1
Phase 2 wire + ground. No neutral is needed except
for units rated 120 volts. Heating elements and the
universal power supply are powered directly from
line voltage.
NOTICE:
Double brewers only are provided with
dual independent heating tanks. The L1 leg of single
phase double brewers is routed through a circuit
breaker to prevent the possibility of overloading the
branch circuit in the event of both heating elements
activate at the same time.
The universal power supply provides 24vdc to all control
components (solenoids, lights, valves, motors, etc.).
The chassis must be grounded. A ground connection is
provided next to the terminal block.
1. Flip power supply to machine “ON” at the branch
supply disconnect. Then flip power switch located
on the back of the machine to the "ON" position
and allow the water tank to fill. The display on the
front should illuminate and machine may make a
subtle hissing sound while filling.
Note:
A watchdog circuit monitors the fill valve “ON”
time. If the “ON” time exceeds 3.5 minutes
continuously, the brewer will display message “ER1”
and cease operation. Normal initial fill time on some
models exceeds 3.5 minutes. Turn off power to brewer
and turn back on; this will reset the controller and allow
brewer to complete filling.
2. Once the brewer is full, it will take 15 to 60 minutes
to heat, depending on model, input voltage,
starting water temperature, and number of brew
heads.
3. Insert the brew basket(s) and place a shuttle under
the basket(s). Brew at least one batch from each
side. Check the level in the container to be sure the
brew volume is correct. Remember that when using
coffee, the level will be lower. Do this for all batch
sizes. The water must be hot to check the levels. If
adjustments are needed, see the
Adjustments
section of this manual.
CAUTION: HOT LIQUID HAZARD
Do not transport brewer without draining water
tank(s) first.

WARNING: ELECTRIC SHOCK HAZARD
This machine is equipped with a power switch on the
back of the machine which disconnects the low
voltage power supply circuits only. Heating circuits are
always powered on when the branch circuit is on.
Disconnect power at branch circuit before
servicing.
WARNING: ELECTROCUTION HAZARD!
Never use the ground conductor as a neutral. This
could cause electrocution.
WARNING: ELECTROCUTION HAZARD!
This appliance is IP20 rated, and shall not be cleaned
with pressurized water.
