INTRODUCTION TO THE UNITS
There are two (2) styles of brewers covered in this
manual.
The "front loading" MODEL 8516 is a unit that positions to the rear of the counter and is completely
operated by store personnel. All operations such as
brewing, keeping coffee warm, serving coffee and
drawing of hot water are performed from the front of
the unit.
A companion "rear loading" MODEL 8518 is a unit
that may be positioned at the front of a counter. This
unit differs from MODEL 8516, as the hot water faucet
and the warmer stations remain at the front of the unit,
while the brewing and control functions have been
placed in the back of the brewer making operation of
the unit easily available, and a step saver for store
personnel.
MODEL 8516 and 8518 UNITS:
A. Bot h units have two (2) independent brewing
sections in each brewer,
1. One brewing section has a water faucet
for drawing cups of hot water while the
other section is for brewing only.
2. In either unit, one brewing section can be
used alone or both may be used at the
same time.
3. Each unit has six (6) warmer stations for
keeping decanters of coffee hot and
available.
4. All Brew Chambers and Decanters are
readily interchangeable between section
to section of a brewer or from brewer to
brewer.
5. Each brewing station of a unit requires a
separate:
a. Power source of 115/230 Volts, A.C.,
60 Hertz, SINGLE PHASE, Four(4)
Wire Supply capable of handling a
20 AMP load.
b. Water input line connected to a single
water source hose line of 3/8"
minimum size.
PRE-INSTALLATION INSTRUCTIONS
GUIDE TO THE INITIAL INSTALLATION and TANK FILLING SEQUENCE.
1. Check the Tank Heater Switch in both brewing sec tions of the unit to be sure it is in the OFF position.
They must remain OFF from Step 1 thru Step No.
9. A Tank Heater Switch controls the main heating
element in each brewing section of the unit, and it
must not be energized before the tank is filled with
water, thru Step No. 5. The Tank Heater Switch
also serves to de-energize the Brew Start Switch,
preventing brew cycles of cold water while the
Tank Heater Switch is in the OFF position.
2. Connect each brewing section of the unit to a
power source, see Electrical Installation on Page 4.
3. Connect each brewing section of the unit to the
water supply line, see instructions on Page 5.
4. Slide both Brew Chambers in place and SET AN
EMPTY DECANTER UNDER EACH BREW
CHAMBER.
5. Pour a full decanter of water thru the pour-in
door on top of each brewing section of the unit.
Wait two (2) minutes and repeat. Repeat a third
time for the non-faucet brewing section of the
unit. Water will start flowing into the decanter
during the third cycle (second cycle from water
faucet brewing sec tion) indicating that the tank
is filled with water.
6. After water flow stops, remove, empty and
replace the decanter under each brew chamber.
7. Plug in both power cords to the source
receptacles. Water should be connected to the
unit and ready to go. Recheck and correct any
leaks.
8. Turn on electric and water at source.
9. NOW — PRESS BOTH TANK HEATER
SWITCHES TO ON position and leave them
ON.
10. Proceed with initial Brew Cycle Set -up
Instruction on Page 6, and then to Brewing of
Coffee.

ELECTRICAL INSTALLATION for MODELS 8516 and 8518
IMPORTANT: Prior to starting the electrical hook-up, check
power source and electrical receptacle for proper single
phase voltage supply. Figure 3 details the power
requirements of each brewing section of a unit.
CAUTION: DO NOT CONNECT TO A THREE (3) PHASE
POWER SOURCE OR ANY OTHER THAN AS NOTED
IN FIGURE 3, AS DAMAGES TO THE UNIT CAN
OCCUR THAT ARE NOT THE RESPONSIBILITY OF
THE MANUFACTURER OF THE UNIT
There are two (2) independent brewing sections in each
unit, and each brewing section draws 20 AMPS of power.
Each brewing section must be connected to a separate
power source, capable of supplying:
115/230 Volts, A.C. 60 Hz., Single Phase, four (4) Wire, 20
AMP service.
For power line cord, use #12 gauge wire suitable for 75
degrees C. All wiring must be in accordance with local
electrical codes.
1. Do not assume the GREEN earth ground wire
can be used as a neutral. The GREEN earth
ground is a protection circuit not intended as
part of the power lines.
2. Recheck at this point — the tank heater and
operation switch, on the front panel of each
brewing sec tion of the unit, must be in the OFF
position.
3. To install power cords, remove rear and bottom
cover panels of the unit for access to the power
junction blocks. See Figure 3. A separate
power cord must be wired into each junction
block thru either the rear or thru the bottom
opening. If bot tom access is to be used,
remove the two (2) snap-in Plug Buttons, and
transfer them to the power cord entrance holes
in the rear of the unit.
4. Recheck the Tank Heater Switch in each
section — it must be in the OFF position. Plug
in both power cords, check voltages at both
terminal blocks to be certain each conforms to
Figure 3 designations.
NOTE: At this point, unplug each power
cord and go to Step 3 of Initial
Installation Instruction Guide.
4
CONNECTING WATER SUPPLY LINE TO THE UNIT
Complete the electrical installation
before starting the water connections.
WARNING:
DO NOT PLUG IN OR ENERGIZE THIS UNIT
UNTIL INSTALLATION INSTRUCTIONS ARE
READ AND FOLLOWED.
Before starting water hook-up, check to be sure both power
cords of the unit are unplugged.
Unit must be installed on a water line with a flowing
pressure between 20 PSI and 90 PSI. If water pressure
does not fall into this range, or varies greatly a pressure
regulator should be installed.
IMPORTANT: Flush the water line a minimum
of three (3) minutes before connecting to the
unit. The unit should be connected to COLD
WATER.
Each brewing section connects to a short length
of 1/4" O.D. tubing, preformed to go beneath the
unit. Each preformed tube connects to a 1/4"
Male Flare leg of a "TEE" fitting. The remaining
leg of the "TEE" fitting is a 3/8" Male Flare that
connects to a single 3/8" incoming water supply
line, as shown in Figure 4.
After water hook -up is completed, continue to
follow Pre-lnstallation Guide Instructions No. 4
thru 10.
5
INITIAL BREWING CYCLE SET-UP
and OPERATION GUIDE
1. Unit is now connected to power and water. Both
water tanks have been filled. The Tank Heater
Switch on each brewing section is in the ON position and the water is heating in both brewing
sections.
2. On Water Faucet Section of each unit, draw off an
ounce or two of water from the faucet, two or
three times during the initial tank heating process,
to relieve air and expansion pressure in the hot
water faucet lines. This relieves "spitting with
pressure," when a cup of hot water is drawn from
a newly installed unit.
3. Initial heating time, at start up, will range from six
(6) to eight (8) minutes. The GREEN signal light
will turn ON when the water reaches brewing
temperature.
4. When GREEN signal light turns ON, press brew
start switch. Hot water will start to flow
immediately and assure that the tank and system
are full of water.
C. Turn Timer adjusting knob: The Timer is
very sensitive, so make adjustments one
(1) mark on the dial at a time. A one (1)
mark change on the dial approximates
three (3) ounces of water delivery change.
The factory timer set ting is 38 seconds
when the unit is operated on a flow
pressure of 35 PSI to receive a 60 ounce
water delivery.
1. Clockwise to INCREASE water
volume, delivered during a brewing
cycle or
2. Counter-clockwise to DECREASE the
delivery.
D. Repeat Steps 4 and 5 until desired amount
of water is dispensed during a brewing cycle.
5. Repeat Step 4. After water stops flowing, you
should have a full decanter of water — 60
ounces. In each brewing sec tion, a water flow
control valve and factory preset timer, control the
exact amount of water to be delivered during
each brewing cycle. If, after completing Step 4
the second time, the decanter is not full — 60
ounces of water, or tends to overflow, proceed as
follows:
A. Check water supply line flowing pressure.
Brewer will not operate properly if the line
pressure is below 20 PSI. (You may obtain
your PSI pressure by inserting a gauge in the
incoming water line at the back of the unit).
B. Remove the 2" Plug Button from access hole in
the cabinet front panels. Timer Knob and Face
Plate are in clear view for easy adjustment.
LEVELING THE UNIT
A very important installation operation that must
not be overlooked or ignored, is the "Leveling of
the Unit." For proper unit operation, it is very
important that the unit be level when it is standing
in its proper operating position.
After adjustment of both brew-sections is
completed and the GREEN signal lights have
turned ON, you are ready to brew coffee.
6
BREWING OF COFFEE
1. Remove brew chamber from under Spray Head
and place one (1) Paper Filter into Brew
Chamber. Add your choice of a premeasured
package of FINE GRIND coffee. Shake Brew
Chamber to level off coffee.
NOTE: Use 1-1/2 to 2-1/2 ounces to begin
brewing. Then, if stronger coffee is desired,
use more (to taste) of fine grind coffee. Slide
Brew Chamber in place.
3. Press Brew Switch. Hot water will start
spraying over coffee grounds in Brew
Chamber and coffee will start filling the
decanter. When coffee stops flowing, the
freshly brewed coffee is completed.
IMMEDIATELY remove Brew Chamber and
discard paper filter and used grounds.
4. When GREEN signal light relights again,
Brewer will be ready for another brewing
cycle.
To keep your coffee warm, the Brewers are
equipped with electric warmers which are
activated by a switch. A Red signal light will glow,
indicating WHICH warmer is ON.
2. Place empty decant er under Brew Chamber.
IMPORTANT: ALWAYS USE EMPTY
DECANTER BEFORE STARTING A BREW
CYCLE.
IMPORTANT:
1. Warmers should be turned OFF when not in
use.
2. Do not leave empty decanter on warmer that is
ON.
SERVICING INSIDE THE UNIT
To expose the timer, high limit thermostat, switches
and wiring, etc. inside a unit section, the front panel
must be removed.
To Remove Front Panel:
A. Turn the two (2) pedestal warmer cover plates
counter-clockwise to remove them.
B. Remove the two (2) screws and clips from each
warmer well that holds the front panel in place.
C. Gently pull the front panel forward and lift it off
exposing the unit inside.
WATER FLOW DIAGRAM
PART I
Sequence of Operations:
WATER FLOW FOR BREWING OPERATION
(Both Brewing Sections)
1. Pushing brew Start Switch energizes the Timer.
The Timer then energizes the Solenoid Valve,
allowing water to flow into the Basin Pan and then
into the Hot Water Tank. The length of time the
Solenoid Valve is energized is controlled by the
Timer setting.
2. The water entering the Hot Water Tank from the
Basin Pan, flows to the bottom of the Tank
through the Water Inlet Tube.
3. The addition of water into the bottom of the Hot
Water Tank causes the hot water at the top of the
Tank to flow out through the Outlet Elbow of the
Tank Cover, to the Spray Head.
PART II
Sequence of Operations:
WATER FLOW FOR FAUCET OPERATION
(Faucet Section Only)
1. The incoming cold water supply connects to a "T"
Inlet Fitting on the Unit. Water flows from the "T"
Inlet Fitting through the Inlet Tube, Needle Valve
and Formed Inlet Tube into the input connection of
the Water Coil.
2. The Water Coil is submerged in the Hot Water
Tank and draws heat from the surrounding hot
water. Water flowing into the Water Coil is then
heated and flows out through the Formed Outlet
Tube to the Faucet. (The water flowing through the
Water Coil, which feeds the Faucet is not controlled by the Solenoid Valve. This portion of the
system is always under pressure and is controlled
by the Faucet. Opening the Faucet allows the
water to flow through the Water Coil system.)
3. The Needle Valve, in the system, controls the
volume of flow from the Faucet and is adjusted to
allow a gentle stream of water to be dispensed
through the Faucet, without splashing into the cup.
(The Faucet is intended as a cup to cup hot water
supply.)
NOTE: Drawing hot water from the Faucet,
during a Brewing Cycle does not affect the
volume of the finished brew.

volume, turn timer knob clockwise for a longer cycle
time, or countercycle time.
NOTE: At 35 PSI water flow, into the unit, a change of
three (3) ounces in delivery occurs with each
face.
