INSTALLATION AND OPERATION:
STANDARD INSTALLATION
1. Before connecting the fan, rotate the impeller with your hand and check that it is not blocked and
that it turns smoothly.
2. Connect the fan and check that the rotation of the impeller is according to the arrow indicated on
the label. Check that there are not abnormal noises or vibrations.
3. This is a fan conceived for duct installation. Current should be measured the first time it is
connected to source, check that it does not exceed the rated current indicated in the fan plate.
CONNECTION DIAGRAMS
TRANSPORTATION AND STORING
The transport agency and intermediaries that have been involved in the process of transportation and
storing until final destination are liable for any damages incurred during this process. They should also be
responsible for all the necessary paperwork involved to attend and solve with the client all the damages
incurred not covered by the manufacturer’s guarantee.
Any hits or bumps can damage the most sensible components of the fan like the bearings, motors or the
rotating pieces like the turbines or propellers (elements that can be deformed or stuck resulting in their
unbalancing).
While being stored until later installation, the protection must be guaranteed against: dust, rain, UV rays
(direct exposing to sun), high atmospheric humidity, and sudden changes of temperature. These harmful
agents are the main cause of sudden deterioration of the fan as they can damage it by rusting the
components and deteriorating the coatings.
QUALITY CONTROL
FUNCTIONING: All fans before delivery are submitted to an electric security and functioning test. Hence if
the fan has not suffered any damage during transportation and is installed correctly following these
instructions, the correct functioning is assured.
BALANCING: The rotating element “propeller or turbine” of the fan has dynamically balanced and may
experience some residual unbalancing within the accepted tolerances according to the regulations
ISO1940-1 and ISO10816-1, quality Q 2.5 or Q 6.3 depending on the models. Still it is advised to verify
before installing it by manually rotating such element and check that no friction or any bumps or
deformation appear due to transportation damage. Do not install nor turn on the fan if any damage is
visible, check first with our technical department

PRODUCT GUARANTEE
CASALS will always supply the requested fan and in accordance to all specifications that the service or
installation requires. Therefore, all elements used in the chosen model are only suitable for the working
conditions specified by the client in the purchase order.
IMPORTANT: CASALS is exempt of any responsibility of any possible accident caused by the
wrong manipulation of the fan and/or for non-compliance of all the warning and security
regulations detailed in this manual.
GUARANTEE PERIOD: The fans are guaranteed for 1 year after the purchasing date (keep the invoice).
Such period will expire even if the fan has not been installed nor used immediately after its acquisition at
CASALS. The guarantee will not be valid if there is any damage or breakdown of the fan or third parties
affected by wrong use or inadequate purpose, normal worn out, overcharge or any external manipulation
not done by CASALS technical dept. The obligation inherent in this guarantee is limited to the replacement
of defective parts previously examined by our specialists.
Installation, maintenance, possible modifications and repairing services of the fan must always be
done by trained specialists. During the guarantee period of the fan, repairing can only be done
under previous consent from CASALS and by authorised shops and staff. CASALS WILL ALWAYS
DETERMINE WHERE ANY REPAIRING SHOULD BE DONE ON FANS THAT STILL HAVE A VALID
GUARANTEE AS WELL AS THE TRANSPORT AGENCY USED FOR THE MOVING IF NEEDED. THIS
GUARANTEE DOES NOT COVER THE TRANSPORT COSTS OF ANY SMALL FANS TO THE
SUGGESTED TECHNICAL SERVICE.
NON CONFORMITY RETURNS: Returns of non conformity material will only be accepted whenever there
is an administrative error, change or supplying mistake, if previously agreed by our commercial dept or
SALES REPRESENTATIVE and also the return form is filled accordingly. The transport agency will be
determined and agreed by CASALS. No return will be accepted without the form filled completely.
NEW MATERIAL RETURNS: If there is a mistake from the client’s side, 25% depreciation will be applied
on the new material returned. The transport costs will be assumed by the client.
INSTALLATION AND START UP OF THE FAN
ELECTRICAL CONNECTION AND INSTALLATION: Each model fan has a connection drawing inside the
terminal box. The feeding cable connection should be done inside such terminal box of the motor or fan. It
is important that the feeding lines and other components used in the installation meet the requirements of
the valid regulations of industrial installations.(“Low pressure electrical regulation”) and that the protection
system are in accordance to the power of the fan (Motor protection system, differential protection, wiring
limit and ground system).
MAINTENACE OF THE FAN
It is recommended a complete check up of the fan and its installation after the first 24 hours after start up,
by electrically disconnecting it from the network in order to avoid accidents. In installations where the fan is
usually not operating, periodically inspect the fan maximum every 6 months.
CONSIDERATIONS DURING REVISIONS: The following are some points to be taken into account during
a revision to guarantee correct functioning of the fan:
1. The functioning of the fan must be smooth and free of vibrations.
2. The ampere consumption (A) should be measured with a hook-on meter or tester can never exceed the
nominal consumption “In(A)” specified in the motor’s plate.
4. In applications where the fan works in a high dust or greasy air environment, the blades of the impeller
or propeller can be unbalanced due to the accumulation of particles and consequently damage the
bearings. Therefore, cleaning of the rotating element must be done periodically using the maintenance
stops or whenever the fan vibrates or does not work correctly. Never leave the dust inside the fan. Avoid
accumulations of dirt, dust, grease, etc. it is main cause of fires and its spreading.
