1. GENERAL DESCRIPTION OF THE MACHINE

This INSTALLATION, OPERATION AND MAINTENANCE manual applies to dryer models ED240, ED340,
ED460, ED660, ED900 and ED1250 in the different heating and control systems.

1.1. Dryer description

The essential features of the dryer are as follows:

1.1.1. Construction features

 Front-loading rotary dryer.
 Stainless steel drum.
 Drum with large perforation area consisting of pressed holes that aid the distribution of the drying air flow.
 Drum with rear axle supported by double bearings.
 Double glazed drum access door with air cavity (an option without air cavity is also available).
 Lint filter that has a large surface area and is easy to access for cleaning.
 Rust resistant external structure.
 The drum rotation by an asynchronous AC motor controlled by an inverter.
 Suction by an asynchronous AC motor controlled by inverter for ED900 and ED1250 models only.
 Drying flow output adjustable with variable opening flap.
 Three possible heating options:
Electric heaters
o
Atmospheric burner with gas input controlled by double winding solenoid, Class B and Class J (in
o
accordance with EN1020).
Pressurised steam exchanger.
o

1.1.2. Functional features

 Dryer operation controlled by microprocessor.
 Control of the temperature, drying time, drum rotation speed and linen wetness.
 Suction motor speed control on ED900 and ED1250 models only. This motor is operated by an inverter,
which makes it possible to adjust the ventilation to the particular characteristics of each facility and optimise
its performance.
 Operation of the machine adaptable to the possibilities of the installation and the needs of the user.
 Motor rotation safety control.
 Transmission by belt between the motor and the drum shaft.
 Detection of air flow losses by pressure switch on models ED260, ED340, ED460 and ED660; and by
mechanical pressure switch on models ED900 and ED1250.
 Inverter activated motor controlled by the microprocessor. This technology takes advantage of all the
features offered by inverter technology, resulting in a significant reduction in noise, vibration and wear on all
the machine components and the matching of the drum rotation speed to the specific needs of each
program.
 Multiple controls that ensure the safe use of the machine.
