4.1

Inspection of the installation and settings

Check list:

Prior to commissioning and initial start-up, it must be guaranteed that



the fan is installed vibration-free and mechanically secured,



all components are cleaned both on the inside and the outside and are free from foreign bodies,



all intake and pressure ducts connections are leak-proofed



all rotating parts are protected against unintentional contact,



the electrical connections are installed and their function tested,



a lockable revision switch is available to which the fan is connected



the equipment is functionally tested,



the safety inspector has made sure that safety equipment exists,



the operating personnel is familiar with the operating manual,



the safety inspector has given his approval for the operation of the installation and that no external

persons are present in the plant area

If envisaged by procedural regulations provided by the operator, minutes have to be taken on the

commissioning work, including the observance of the check list.

4.2

Drive

The fan is driven by an electric motor which is connected either directly to the impeller shaft.

The motor electrical specifications are indicated on the motor's rating plate or in the motor manufacturer's

data sheet.

When speed is controlled by means of a frequency converter, the maximum speed is limited by COLASIT to

the value indicated on the manufacturer's rating plate.

If the frequency converter is not supplied by COLASIT, the operator is responsible for

compliance with the maximum speed limitation. In this case, COLASIT will not assume any

liability for damage that may be attributed to exceeding the maximum speed.

In order not to overload the fan mechanically, acceleration and braking times of at least 15sec. must be

observed for < 1.5kW rated motor power and 30sec. for > 1.5kW rated motor power.

Depending on the maximum available starting current of the frequency inverter, a longer acceleration time

may be necessary to avoid an error message.

4.3

Electrical installations

The electrical installations may only be carried out by an authorised electrician in accordance with the

regulations prevailing at the site at which the fan is installed.

To interrupt the power supply, a revision switch must be provided. It is advisable to mount this switch in the

vicinity of the emergency exit.

Please request confirmation from an in-house electrician that the electrical installations were carried out and

tested in accordance with regulations, that all functions were tested (or simulated) and that the rotational

direction is correct.
