• Before any installation work is started, en-
sure that fan unit equipment is correct for
application. Location for installation is sol-
id, level, fl at and suitable for mounting fan
unit assembly.
• Fan unit should be located in position, and
assembled with any accessory equipment
supplied, on relevant mounting, antivibra-
tion mountings, safety protection guards,
on a solid level base to avoid any distortion
and misalignment and with correct air di-
rection as shown on nameplate. Fan unit
should then be levelled on any anti-vibra-
tion mountings. Flexible connectors must
be taught to ensure no disruption to air
fl ow, especially on inlet to fan unit.
• Make sure there are no loose elements near
the fan unit. When the fan unit is mounted in
a duct, check that it is clean of any elements
and exclusively used for ventilation system.
• The electrical installation must include a
double pole switch with a contact clearance
of at least 3 mm, correctly sized and in ac-
cordance with the electrical standards of
the country of installation.
• For electrical connections follow the wiring
diagram "A" indicated in this manual.
The fan unit classifi ed as Residential Ven-
tilation Unit with control factor 0,65 have to
comply with the requirements of the Europe-
an Directive 2009/125 and must be installed
following the local demand control defi nition
given in the regulation nº1253/2014 (See the
wiring diagram "B", as example).
START UP
• Check fan unit equipment name plate data
is appropriate to the location electrical sup-
ply, especially Voltage, Frequency, Phase,
Amps, speed are correct.
• Check earth connections, electrical termi-
nations and terminal box lid, with any seals,
if fi tted, are correct.
• In compliance with Machine Directive, if the
fan unit is accessible to operators and is a
health and safety risk, adequate protection
must be fi tted, information for safety equip-
ment, including guards, can be found in
S&P accessories catalogue.
• Check all rotating parts have free, unob-
structed movement.
• Check there are no foreign bodies inside
the fan unit or that can be drawn into, or fall
into fan unit.
• Check the structure is complete and has no
damage. Check installation and area is safe
and energise fan unit and start motor.
• Check that the impeller and airfl ow direc-
tion is correct, and there are no unusual
vibrations.
• Check current does not exceed fan equip-
ment nameplate data.
• If any of the electrical safety devices blow,
the fan unit must be quickly disconnected
from the mains supply. The whole installa-
tion should be carefully checked before try-
ing to start up the fan again. After two hours
of operation, check that all fi xings are tight
and adjust if necessary.

MAINTENANCE
Maintenance/repairs must be carried out by
competent and local regulations. Fan unit
equipment should be electrically isolated
and locked out before any work started.
Fan unit equipment should be regularly
cleaned, frequency depending upon service
load and application, but no less than every
year. Cleaning should include all areas where
dust can accumulate in the fan equipment.
Special attention should be made to any unu-
sual sounds, vibration or temperature.
If any problems are detected the fan unit
equipment should be stopped immediately
and cause inspected. The impeller and blades
should be regularly checked for damage that
could cause imbalance in the moving parts.
