7. IMPLEMENTATION
7.1. SAFETY CHECK
Check to see that all mechanisms and electrical protections are in place and connected.
The following checks must be made before the unit can be switched on:
Make sure that an uncontrolled start-up of the fan unit during implementation is impossible (such as with
a lockable work switch)!
7.1.2. BEFORE STARTING UP
- Turn the impeller/motor by hand to ensure free running of the impeller.
- Is the unit / motor/ impeller clean, free in- and outlet / no parts in the in- and outlet.
- Is the correct power supply (V/Ph/Hz) according the indication on the nameplate.
- Is the unit / motor mounted correctly and flat on a ceiling without any torsion → correctly aligned.
- Make sure that all four bolts of the mounting plate of the unit are tightened firmly and correctly.
- Are the bearing lubricated correctly, also after long term storage.
- Is the motor / unit correctly grounded.
- Is the inlet air ventilation passing freely through the motor to ensure the cooling of the motor.
- Are all required unit/ motor protection on.
7.1.3 MAKE SURE THAT THE CONNECTED REGULATING EQUIPMENT IS FUNCTIONING
PROPERLY
The fan unit may only be switched on once all safety measures have been applied!
7.2. CARRY OUT CHECK WHEN COMMISSIONING AND RECORD RESULTS
IN THE COMMISSIONING REPORT.
Commissioning may only be carried out by qualified persons. Warranty claims can only be made if commissioning
work is carried out correctly and written evidence is provided.
Turn the fan unit on for a short time to check that the rotational direction of the impeller conforms to the
rotational direction given by the arrow on the fan unit. If the direction is wrong, the motor (under compliance
with the safety precautions) must be electrically reversed.
