INTRODUCTION

MODEL 8702 SATELLITE COFFEE BREWER
WITH HOT WATER FAUCET, manufactured by
Bloomfield Industries, is designed to brew a
satellite of coffee at the press of a switch and to
hold 1 1/4 gallons of hot beverage at the correct
temperature for ser ving.

• Satellites are electrically heated —may be
"plugged into" the brewer to keep coffee at the
correct temperature for serving.

• Satellites may be moved and plugged into any
standard wall receptacle so fresh brewed coffee
may be kept hot and dispensed locally.

• Operates on 30 Amps, 5800 Watts, 115/230 or
120/208 Volts, 50/60 hz., single phase three (3)
wire service.

• Requires a water flow rate of one (1) gallon per
minute at a minimum pressure of 20 PSI.

• Brews 212 oz. of coffee in approximately 7
minutes.

• Is all Stainless Steel Construction.

• "Energy Saver" Tank Heater on/off switch
conserves energy.

• Hot Water Faucet on the front of the brewer
provides hot water for hot beverages at anytime
without affecting the coffee brew volume.

• "Ready to Brew" light to indicate proper water
temperature to insure uniform quality of brewed
coffee.

• Exclusive "Water Spray Disc" with 12 holes.
Water drips slowly and gently over the coffee
grounds, causing a floating action and complete
saturation of all the coffee grounds.

• Factory pre -set thermostat so brewer is ready for
operation on installation.

• 4-minute Solid State Timer.

• Low watt, density 5500 Watt heating ele ment for
longer life, more efficient operation.

• Teflon color coded wiring, keyed to co lor tabs at
connection points.

PRE-INSTALLATION INSTRUCTIONS

FOR MODEL 8702 TWIN SATELLITE

BREWING SYSTEM

WARNING:

DO NOT PLUG IN OR ENERGIZE THIS UNIT UNTIL INSTALLATION INSTRUCTIONS ARE READ AND
UNDERSTOOD.

CHECK THE ELECTRIC SOURCE THAT WILL FEED THE UNIT.

1. Check the female power receptacle and the circuit breakers.
A. The power receptacle must be a 30 AMP, Single Phase, NEMA #L14-30 receptacle wired for 115/230

or 120/208 Volt to match the power requirements shown below.
B. Circuit Breakers in the control cabinet must be of 30 AMP rating.

Source Receptacle

NOW THE UNIT MAY BE SET IN PLACE.

1. Be Sure Tank Heater Switch is "Off."

2. Follow Plumber's Instructions.

3. Follow Electrician's Instructions.

YOU ARE NOW READY TO FILL THE TANK WITH WATER.

1. Follow initial operation instructions.

incoming water line in a convenient location,
close to the unit.

flow at one gallon per minute.

NOTE: Unit must be installed on a water line with
pressure between 20 PSI and 90 PSI. If water
pressure varies greatly or does not fall into this
range, a pressure regulator should be installed.

NOTE: Line connections to machine must conform
to local codes.

5. Connect the incoming water line coupler
assembly to the 1/4" male end of the water
strainer. Observe arrow direction for water
flow.

6. To delay build up of lime deposits in water tank,
we recommend the use of a Water Conditioner
such as Everpure QC7-MH.

Page 5

The National Sanitation Foundation requests a
provision be made in the incoming water line for
flexibility. This is necessary to allow tilting or moving
the machine for proper cleaning underneath, etc. A
tightly coiled length of copper tubing located on either

side of the water strainer would help comply with this
request.

ELECTRICAL INSTALLATION

Electrical requirements: 115/230 (120/208) Volts
A.C. 50/60 hertz, 4 wire with ground, single phase,
30 amp wiring required.

Warranty is void if Brewer is connected to any
voltage other than specified above.

WARNING: Brewer must be properly grounded to

prevent possible shock haz ard. DO
NOT assume a plumbing line will
provide such a ground.

1. Energy Saver Tank Heater Switch on front of
Brewer must remain in OFF position until
plumbing is connected and Brewer is initially
filled with water. The switch must NOT be turned
on until after Step 6 is completed in the initial
operation instruction, See Page 7.

2. Electrical service line cord and NEMA
Plug and receptacle, or equivalent, must be
furnished by installer. Use copper wire on ly of
#10AWG wire size.

3. Plug power cord to power source.

4. After connecting service as specified, test the
voltages on the field wired side with a volt
meter. Do not turn on tank heater switch.

5. If plumbing connection has been made, the
Brewer is now ready for "Initial Operation
Instructions." If plumbing is to be done later, be
sure power is "OFF" and Brewer is not plugged
into outlet.

NOTE: Line connection to machine must conform to
local codes. See Diagram above.

Page 6

INITIAL OPERATION INSTRUCTIONS

Electrician's and Plumber's Instructions should be
followed carefully before proceeding with Initial
Operating Instructions.

Be sure all electrical and plumbing connec tions are
tight.

1. Open water inlet valve.

2. Make sure Energy Saver Switch is in OFF
position.

3. Connect electricity.

4. Place empty Satellite in brewing position.

5. Place empty Brew Funnel into brew rails and
turn left or right so that handle is over receiving
Satellite.

NOTE: Handle must be turned all the way to left

or right so Micro Switch is engaged.

6. Press "Brew" Switch. Repeat a second time,
allowing five (5) minutes between cycles. Water
will begin to flow through brew funnel into
Satellite during third cycle.

7. Turn Energy Saver Switch to ON. On initial
warm up, some water may flow into the brew
funnel due to expansion of cold water in the
Tank.

8. Allow 20 minutes for initial water heat up. Time
will vary with incoming water temperature.

9. When correct brewing temperature is reached,
READY LIGHT will come on. Make sure
Satellite is empty. Press Brew Switch and run a
cycle of hot water only. At the end of

this cycle, Brewer will be ready for checking
timer adjustment.

10. Check a cycle of water ONLY to determine
water volume delivery. Appro ximately one (1)
inch down from the top of the Sight Glass
Assembly, on the shield, there are two (2) lines
stamped in the metal. The water should rise in
the Sight Glass, to a level between those lines
to be considered as a full delivery volume.

11. The Solid State Timer is pre-set at the fac tory to
run 146 seconds and allow 224 ounces of water
to flow into the Basin Pan. Timer adjustment is
located behind the 2 inch Plug Button in the
Front Panel in the upper left area. To adjust,
remove snap-in plug and turn dial clockwise to
increase timer cycle and water volume, or
counter-clockwise to decrease timer cycle and
water volume.

12. Replace snap-in plug.

13. The Thermostat is pre-set at the factory for
195°-205°. The Thermostat Adjustment is
located behind the Plug Button in the upper left
section of the Front Panel. To adjust, turn knob
clockwise to increase temperature, or counter­clockwise to decrease temperature level of the
water in the tank.

14. Replace plug button.

15. Brewer is ready for use.

16 If water supplied to brewer is softened or

brewed coffee is too strong, see Adjustment
Tools and By -Pass Adjustment.

BREWING OF COFFEE

NOTE: To be sure water brewing temperature is

correct do not start a brewing cycle until
READY LITE is ON.

1. Slide brew chamber from the brew rails and
check to be sure wire rack (brew basket) is in
place in the brew chamber. Proper timing and
brewed coffee flow, through the brew chamber,
cannot occur without it.

2. Place one BLOOMFIELD filter paper into brew
chamber and add a pre -measured package
(standard package is 8. 0 ounces of grounds)
of URN GRIND coffee. Shake brew chamber to
level the filter paper and coffee bed.

3. Make sure satellite is empty before starting a
brewing cycle. Place empty Satellite in brewing
position and plug Satellite Cord into receptacle
inside of unit. Turn ON Satellite Heater Switch.

4. Slide brew chamber into brew rails and turn to
LEFT or RIGHT so micro-switch is engaged by
actuator tab on front of brew chamber.

5. Press BREW SWITCH - this action activates the
timer and water solenoid to automatically
complete a brew.

6. When the brew is finished and coffee flow has
stopped remove the brew chamber and discard
the used coffee grounds and filter paper.
