Manual

HYDRAULIC & STEAM

The Hydraulic & Steam section of this manual details the hydraulic components of the Egro 5511. The
hydraulic components are broken down into three main sections:

Coffee Boiler

,

Steam Boiler

, and

Brew Group Assembly

.

Coffee Boiler

HOT WATER SOLENOID FITTING

Sends hot water to the mixing chamber when
the hot water solenoid opens.

TEMPERATURE SENSOR

HOT WATER SOLENOID FITTING

EXPANSION VALVE

TEMPERATURE SENSOR

Reads the temperature of the water in the boiler.
Sends temperature reading to motherboard.

EXPANSION VALVE

Relieves coffee boiler pressure at 11 bars.
Relieved pressure flows into drip tray via
silicon tubing.

BREW SOLENOID

BREW SOLENOID

Located on the bottom of the boiler. 3-way valve.
Waste is connected to drain T-fitting, open goes to
