INITIAL START-UP

7.1 Before Starting up the Extractor:
 Check that no objects or tools have been left inside the machine.
 Check that cement or lime residues have not fallen on the blades during the
installation; the resulting fan imbalance would cause harmful vibrations that
would result in rapid wear on the impeller bearing.
 Check that the protection meshes are closed and correctly secured to the
machine.
 The machine should never be operated without the standard mesh protection
guard correctly installed. If it is damaged, it should be replaced immediately and
always with S&P original spare parts, as our replacement parts guarantee the
safety levels required by the Directive and by technical standards.

Due to the existing risks derived from the presence of moving parts and from
the air extracted by the extractor, it is the user's responsibility to protect the fans
outlet area using barriers to prevent access by unauthorised personnel. Mark
the restricted access area using the corresponding danger and/or warning
signs.
WARNING: The mesh protection guards are a passive safety device, and it is
strictly forbidden to remove or force them.

Before starting up the air extractor, it is essential that the presence and the
correct position of the metallic mesh protection guards are checked.
 Ensure that all present personnel are at an adequate safe distance from the
machine.
 Check that the tension in the drive belt is correct, following the procedure
referred to in the maintenance section of this Manual (chapter 8).
7.2

After Start-up:

 Check correct installation ensuring there are no vibrations and/or unusual
noises.
 Check the fan from the air intake side and make sure that the fan rotates anti-
clockwise. If the rotation direction is clockwise, invert any two cables on the
power line (only for three-phase motors).
