Horizontal Installation; Instructions For Repositioning Silencer Housings - FPZ K03-MS Manual De Uso

To avoid overloads caused by pressure fluctuations, install a bypass pressure-relief valve on the suction pipe
in case of operation as an exhauster, and on the delivery when operating as a blower.
If the flow rate has to be reduced, use a bypass valve instead of throttling the suction or delivery.
Protect the suction pipe with a filter with max. degree of filtration 25µm. For the use of filters with filtration
different from 25µm, ask FPZ. Foreign bodies are: dust, sand, gravel, dirt in the pipes, cutting burrs and
shavings, welding slag and spatter, metal burrs and sealant residuals produced when connecting the pipes.
Change the filters regularly.
Size the pipes and choose accessories that minimise pressure losses; therefore:
•
do not fit pipes narrower than the ports of the machine.
•
when installing several machines in parallel, suitably size the manifold and the main line.
•
use large-radius curves and not elbows.
•
do not install valves with a smaller flow than nominal and check valves with shutter opposed by spring (the check valve with
lowest pressure loss is the lightened non-return valve).
•
when used for oxygenation, choose diffusers with low flow resistance (low pressure loss).
Danger due to foreign bodies and dirt entering the unit!
The ingress of even tiny foreign bodies causes serious damage to the unit with probable breakage of the impeller blades and the danger
of debris being thrown out!
See INSTALLATION DIAGRAMS in the first section.

HORIZONTAL INSTALLATION

•
Units supplied with standard set-up are ready to be installed in the horizontal position
by means of the feet.
•
The feet have holes for fixing; use all the holes and choose the appropriate type of
screw.
•
Remove the protection on the ports before checking the rotation direction and before
final connection.
•
To connect the unit to the piping, remove the flanges from the silencer housings to
make the appropriate connections using flexible sleeves, thereby avoiding rigid
connections which can cause stress and harmful vibrations.
•
Refit the flanges on the silencer housings complete with gaskets and tighten.
Check the motor rotation direction

INSTRUCTIONS FOR REPOSITIONING SILENCER HOUSINGS

•
The SCL K MOR series has been designed for maximum flexibility in positioning the silencer housings in order to allow different
installation configurations.
•
The blower is normally supplied with silencers positioned as shown in figure A.
•
If this arrangement has to be changed, establish the required arrangement of the silencer housings.
See the diagram provided in the first section of this manual
•
Remove and refit the housings and blind flanges according to the following diagram to obtain the desired configuration
Removing the blind flange (B)
•
Place the unit horizontal, resting the feet on a flat and stable surface.
•
Undo the screws and remove the blind flange and gasket
Removing the silencer housing (C)
•
Undo the screws.
•
Remove the silencer housing with gasket.
