INTRODUCTION

This compact, easy-to-operate equipment produces consistently fine espresso and related beverages with
the push of a button. The brewer is selectable to deliver one of eight different programmed amounts of
beverage. All of the critical functions of the brewer are electronically controlled.

WARRANTY

Bunn-O-Matic Corp. (“Bunn”) warrants the equipment manufactured by it to be commercially free from defects in
material and workmanship existing at the time of manufacture and appearing within one year from the date of

or that, in Bunn’s judgement, has been affected by misuse, neglect, alteration, improper installation or operation,
improper maintenance or repair, damage or casualty.

THE FOREGOING WARRANTY IS EXCLUSIVE AND IS IN LIEU OF ANY OTHER WARRANTY, WRITTEN OR ORAL,

the defective equipment prepaid to an authorized Bunn service location. If Bunn determines, in its sole discretion, that
the equipment does not conform to the warranty, Bunn shall repair the equipment with no charge for parts during the
one year warranty period and no charge for labor by a Bunn Authorized Service Representative during the one year
warranty period. If Bunn determines that repair is not feasible, Bunn shall, at its sole option, replace the equipment or
refund the purchase price for the equipment.

(Revised January 1996)

BUNN Espress® Model ES•1AF

SITE REQUIREMENTS

PHYSICAL

The brewer is for indoor use only on a sturdy counter or cart. It is 16” (40.5 cm) wide, 20” (50.8 cm) tall and

19.25” (48.9 cm) deep. The brewer weighs approximately 88 pounds (40 kg) with the water tank filled.

ADJUSTABLE LEGS

Remove the four rubber feet from the brewer and install the four 4” adjustable legs supplied with the brewer.

Place the brewer on a counter or cart having sufficient space for easy access to water, electricity and drainage.

PLUMBING

The brewer must be connected to a cold water source with operating pressure between 20 and 90
psi (1.5-6.5 bar) from a .5” or larger supply line. Install a shutoff valve in the water line before the brewer.
Install a regulator before the brewer when the pressure is greater than 90 psi (6.3 bar) to reduce it to
45-60 psi ( 3-4 bar). The enclosed water strainer, water inlet hose assembly and drain hose must be
installed.

NOTE-Only softened or demineralized water should be used in this espresso brewer to reduce the service
problems caused by naturally occurring elements in your local water supply. A polyphosphate feeder is
not recommended because it does not remove minerals.
NOTE-Bunn-O-Matic recommends .375” copper tubing for no more than 25 feet from the .5” water supply
line. Bunn-O-Matic does not recommend the use of a saddle valve to install the brewer. The size and shape
of the hole made in the supply line by this type of device may restrict water flow.

ELECTRICAL

The brewer is equipped with an attached cordset and requires a 2-wire, grounded mating receptacle
rated 120 volts ac, 20 amp, single phase, 60 hz. An electrician must properly install a NEMA 5-20R
connector to the appropriate electrical service on an individual branch circuit to install this brewer.

CAUTION- The brewer must be properly grounded. A plumbing line will not provide an adequate ground.

FROTHER DISCONNECT ASSEMBLY

When installing frother assembly thoroughly wet O-rings
with water. Using the slide bracket on the front panel as a guide,
slide frother assembly into the frother manifold as far as it will
go. Secure frother assembly with attached thumb screw.
