The following checks are carried out before initial operation:
– check for operation according to the intended purpose of the fan
– compare power supply voltage with data on the rating plate
– check fan for solid fastening and professional electrical installation
– check all parts especially screws, nuts and safety grille for tight fit. Without loosing screws!
– test unhindered running of impeller respectively minimum air gap
– check if direction of rotation and air flow direction correspond. Check direction of rotation of impeller (by switching
on for a short time; when checking the direction of rotation wear protective goggles)
– compare current consumption with data on the rating plate
– test functioning of motor protection device
– test protective conductor connection
– check sealing of the connection cable and tight clamp of cable wires
– start operation only if a protection against accidental contact is guaranteed
– check tightness of all connections (if required)
– remove assembly residues from fan or duct
