Installation instructions
General
This instruction is intended for professional installation
and use by trained personnel. Technical skills are required,
for example, when tensioning the belts and replacing
motors, applicable to the trained personnel of the factory.
Replacement of the impeller and bearing require
specialised professional skills. This should be performed
by service personnel familiar with the construction
of the fan. (A separate service instruction is available
for the replacement of impeller and bearing). Electrical
connections must be carried out by an authorized
electrician. A separate installation and maintenance
instruction is delivered with the motor. Professional staff
who is familiar with the safety regulations must carry
out the installation, start-up and operation of the fans.
Tools and protective equipment necessary for preventing
accidents from occurring while installing and operating
the fan must be used in accordance with the national
safety regulations.
