3.1 Intended use
5
The gearboxes have been in particular designed for use in machines in food, cosmetic,
pharmaceutical, medical and similar applications with highest demands on the
cleanability of the machine (hygiene design).
Operation of the HLAE gearboxes is permitted in applications with indirect contact to
foodstuffs.
You may only operate the gearboxes taking into consideration the ambient conditions
defined in this documentation.
Operation of the HLAE gearboxes is permitted in environments with detergents taking
into consideration the conditions defined in chapter 4.5.
Do not exceed permissible operating data.
Only start up the gearbox once the machine into which the gearbox is installed as a
component complies with the provisions of the directives and statutory provisions to be
applied (see Chapter 3.5).
Hygienic design uses
A hygienic design use comprises among others also the connection to the motor and to
the application. It is therefore important that on the part of the customer the
corresponding measures in terms of the hygienic design are taken into consideration. In
order to achieve this, we propose the following measures:
Gearbox:
The gearbox can be mounted in any position. There are no restrictions in this
regard.
Connection to the motor:
To seal the motor flange, an O-ring in the motor's A-bearing shield must be
provided according to hygienic design.
Use the sealing screws according to hygienic design provided by the motor
manufacturer to fasten the motor.
Connection to the application:
To seal the gearbox flange, the O-ring included in the supply must be inserted
in the gearbox output flange.
Depending on the application, the optionally available sealing kit can be used
for sealing. Detailed installation instructions see Chapter 4.2 and 6.4.
To meet the 3-A Sanitary Standard for General Requirements for your
application, the gearbox must be located outside the product contact surface
with at least 1 in. (25.4 mm) clearance between the gearbox and the nearest
product contact surface with the clearance open for inspection.
