SAFETY PRECAUTIONS

GENERAL SAFETY RULES

Do not leave packing materials (plastic bags, expanded polystyrene, nails, cardboard, etc.) within the

reach of children, as these items are a potential source of danger.

Verify that that the electrical data of the machine corresponds with the electrical supply network before

connecting the machine to the power source.

Electrical adaptors, multiple sockets, and or extensions must not be used.

Request a detailed description of the available power from an electrician. The electrical outlet must

have the following safety features:

• Dedicated ground

• Wiring suitable for wattage capacity

• Circuit breaker

Install the machine on a water repellent surface (laminate, steel, ceramic, etc.). Keep the machine away

from heat sources (oven stove, fireplace, etc.) and from extreme cold (the temperature should not fall

below 41° F. KEEP THE MACHINE WARM.

Do not leave the machine exposed to harmful atmospheric agents or place it in damp rooms, such as a

bathroom.

Do not obstruct the suction or dispersion grills and do not cover with cloths or similar.

Store the packed machine in a dry place. Do not store where the temperature may fall below 41° F. Do

not stack heavy items on the packaging.

In an emergency, such as the machine catching on fire, unusual noises coming from the machine,

overheating, etc., IMMEDIATELY disconnect the power and close water taps.

Use only authorized spare parts in order to avoid compromising the safety and proper functioning of

the machine.

Equipment installed incorrectly can cause damage to people and items for which the manufacturer

cannot be considered responsible.

The Egro 5511 requires a NEMA L6-30R recep-

tacle (

P1). The optimal voltage supply is 230V.

Acceptable range is 208V - 250V. If below 208V,

a voltage booster may be required. If above 250V,

a buck n’ boost transformer may be required.

Egro machines do not use a neutral line. A dedi-

cated ground wire is required for proper perfor-

mance.

The incoming water supply should be a male 3/8”

NPT fitting.

The water connector on the Egro 5511 is 3/8”

BSPT.

A 3/8” NPT to 3/8” BSPT fitting will be needed to

connect the incoming water supply to the water

connector of the Egro 5511.

A water softener/filter for the incoming water

supply is REQUIRED.

Connect the incoming water to the softener/filter

and flush with approximately 3 gallons of fresh

water.

Then connect the other end of the softener/filter

to the Egro 5511.

Slowly tilt the Egro 5511 to the right, and screw in

two legs to the bottom left side.

Carefully tilt the Egro 5511 onto the newly

installed legs and screw in the remaining two legs

to the bottom right side.

Locate the two bean hoppers provided. Slide the

hoppers down into the rubber grinder collars on

top of the Egro 5511 (

P3).

No screws or other fasteners are required for

installation.

1.

Remove the right-side panel of the

Egro 5511.

To do this, remove the two screws on top

of the machine (

Locate the brew valve solenoid on the

back-right side of the machine. (P5).

Attach the provided silicon tubing to the

bottom of the brew valve and route it

down through the hole in the bottom panel

of the Egro 5511 (P6).

Make sure the silicon tubing is firmly attached

to the bottom of the brew valve. During the

cleaning cycle pressure will increase, which

can cause the tubing to become disconnected

if it is not properly and securely attached.

3.

Locate the drain hose provided.

Cut a 4” piece from the hose using a utility

knife, and attach it to the barbed drain tray

fitting under the Egro 5511 (

P7).

4.

Locate the plastic T-fitting provided (P8).

· Attach the silicone tubing to the small connec-

tor of the T-fitting.

· Attach one of the large T-fitting connectors to

the 4” piece of drain hose.

· Attach the remaining drain hose to the other

large T-fitting connector (P9).

· Then route the drain hose from down to the

floor drain in a continuous downward slope.

The floor drain must be at least 30mm (1.2”) in

diameter.

(This step is very important because the steam boiler

MUST de-pressurize before it can function correctly.)

After turning on the Egro 5511, press the TS

wand activation button.

Do not try to manipulate the programming of the

Egro 5511 while it is de-pressurizing. You may

only enter programming after the machine has

fully de-pressurized.

Note: If “Error 33” appears on the display screen, turn the

machine off – wait 10 seconds – then turn it back on.

When steam begins to exit the wand, press the

TS wand activation button again to stop the flow

of steam.

DE-PRESSURIZE STEAM BOILER

*ATTENTION: Do not attempt to program the machine until the machine is ready*

When the machine is turned on, it must go through an initialization. During this time do not enter programming,

otherwise an error may occur. You may enter programming after the screen reads “Please Select”.

1.

Remove the screw holding the front door in

place (

P12).

Swing the front door open.

2.

Looking inside the machine, you will see the two

grinders (

P13).

Located on top of both grinders is an adjustment

plate.

3.

Insert a standard screwdriver into the slot on

the adjustment plate (

P14).

Apply gentle downward pressure on the screw-

driver to lift the plate free of the notches that are

holding it in place.

4.

Turn the bean hoppers on top of the Egro 5511

to adjust the grinder burrs.

FINER GRIND

= Turn hoppers clockwise

COARSER GRIND = Turn hoppers counter-

clockwise

Make sure that the adjustment plate is securely

held in place by the notches before removing the

screwdriver from the slot.

Note: While one notch is a seemingly small adjustment, it can

greatly affect the resulting grind. Use small turns, one notch

at a time, to adjust the grinder burrs until the correct grind is

reached.
