1. Check the Power Outlet

This merchandiser is supplied with a service cord for the country of use and is terminated in a grounding type
plug. The wall receptacle used for this merchandiser must be properly polarized, grounded, and of the correct
voltage. Operating the merchandiser from a source of low voltage will VOID YOUR WARRANTY. Each
merchandiser should have its own electrical circuit and that circuit should be protected with a circuit breaker
or fuse conforming to local regulations.

Voltage Check - Place the leads of a voltmeter across the LINE (LIVE) and NEUTRAL terminals of the wall
receptacle. The voltmeter should indicate 110-130 volts ac for 120 volt, 60 Hz locations, or 220-240 volts ac
for 230 volt, 50 Hz locations.

Polarity Check - Place the leads of a voltmeter across the LINE (LIVE) and GROUND terminals of the wall
receptacle. The voltmeter should indicate 110-130 volts ac for 120 volt, 60 Hz locations, or 220-240 volts ac
for 230 volt, 50 Hz locations.

(Amps)

Noise Potential Check - Place the leads of a voltmeter across the NEUTRAL and GROUND terminals of the
wall receptacle. The voltmeter should indicate 0 volts ac. A measurement greater than 1.5-2.0 volts ac could
result in problems for the merchandiser's electronic circuitry caused by electrical noise.

Any deviation from these requirements could result in unreliable performance from your merchandiser.

WATER REQUIREMENTS

The best type of water for coffee brewing is normal hard (tap) water. If your location has chemically softened
water, you should do one of the following things:

•Have a non-softened supply line run to the merchandiser

•Contact your local water filter supplier for information and suggestions

Well water can also be used in the EuroDrink Machine. However, you should have it checked for levels
of carbonates and alkalies. Contact your water filter supplier if these values are relatively high.

What is the Water Pressure at Your Location?

It should be no less than: 10 psi ( 69.0 KPa) at 1/2 gallon/minute

And no more than: 80 psi (522.0 KPa) at 1/2 gallon/minute

If you're not sure about the pressure and flow rate, check with your water company.

What to do With the Water Supply Line:

Locate the supply line at the rear of your merchandiser.
Equip the line with a shut-off valve.

Flush the water supply line before connecting it to the merchandiser. A minimum of five gallons is usually
required before connecting the merchandiser to the supply line. DO NOT flush the merchandiser water
system. If you do, you might introduce water line contaminants into the merchandiser.

Main Controller Card Display. This display consists of two light emitting diodes (LED) mounted on the
controller card.

POWER ON When lit, this red LED indicates electrical power is applied to the controller card.

HEARTBEAT When flashing, this red LED indicates that the controller card is active and the soft-

ware is operating.

NORMAL CONDITIONS:

When the merchandiser is operating normally, you should see a steady red POWER ON indicator
and a flashing red HEARTBEAT indicator. Refer to the maintenance manual if any other condition
exists.

LEVELING THE MERCHANDISER

From a safety standpoint it is very important that the merchandiser be level. A level merchandiser is
less likely to tip over and cause personal injury. Level the merchandiser by moving the leg levelers
in or out for proper adjustment. Pliers or channel locks may be required to loosen the leg levelers.
Level the merchandiser from the right to left and from front to back using a spirit level. When the
merchandiser is part of a bank of machines, it should be leveled in reference to the other machines.

Caution

Have an assistant hold the merchandiser
while you adjust the leg levelers.

SETTING THE QUARTER SWITCH

COIN MECHANISM

If your coin mechanism is not a MARS TRC
6000, skip this procedure and begin loading
the coin mechanism. If your coin mecha­nism is a MARS TRC 6000, flip down the
top front of the mechanism and set the
quarter switch as shown on the drawing to
the right. Make sure switch #2 is in the
down or "off" position.

WATER FILTER CARTRIDGE

If your merchandiser has a water filter option, it cannot be operated without a properly installed water filter
cartridge.

Note

Check the water filter installation record. There is a place to write the vend number on the cartridge. The
filter is normally effective for approximately 26,000 7 oz. vends, 22,000 8 oz. vends, 20,000 9 oz. vends,
or 15,000 12 oz. vends. Local conditions may require more frequent replacement.

Removal

1. Turn the main power switch to the off position.

2. Flip the lock lever UP (view A). The lock lever on the water filter head is used to open and close the
water inlet to the merchandiser.

3. Rotate the locking collar to the left about 60 degrees until it drops to the filter receiving position.

4. Rotate the filter to the left until it drops free of the locking collar.

Installation

1. Align the raised rib near the top of the cartridge with the ribless portion of the locking collar (view B).

2. Push the cartridge up into the filter head (view B).

3. Rotate the cartridge to the right until the lock lever engages the locking collar (view C).

4. Rotate the locking collar to the right until it moves up into the locking position (view D).

5. Push the lock lever DOWN (view E).

Note

Do not flush the water filter cartridge.

Pressure Adjust Control. This control determines the system pressure provided by the air compressor.

Adjust the pressure as follows:
a. With the compressor running, pinch the brewer inlet air tube.
b. Adjust the pressure to read 10 - 12 psi on the gauge.

This will produce a pressure of 3 - 6 psi using regular coffee and 8¼ oz cups. No further air pressure
adjustments should be necessary.
