tion is stopped due to disruption to power supply, en-
sure no risk due to build-up of hazardous substance,
excessive temperature etc. Care may be needed when
restarting fan after disruption to power supply.
• If the fan shall be operated also for daily ventilation,
this shall be subject to weather conditions at the time.
It may be recommended to install wind and/or rain
sensors, so that the HATCH will not open in order to
prevent rain ingress or damage to the opening me-
chanism due to strong wind. However, these sensors
shall not have any priority whatsover in case of fi re
emergency. Under such event, the unit shall operate
regardless of the weather conditions.
Safe installation
• Avoid risk of foreign objects, debris being drawn into,
or falling into fan impeller.
• Ensure no objects or tools remain resting on the
HATCH's frame, as the cover or opening mechanism
may be damaged when closing.
• Allow safe access to fan for inspection, maintenance, re-
placement of parts, cleaning, especially for dust hazards.
• Access with suitable lifting to repair in-situ, should be pro-
vided, greater than largest impeller / motor dimension.
• Ensure all necessary safety guards are fi tted and secu-
re to prevent injury.
• Axial fans should be installed with clear, unobstructed
airfl ow upstream and downstream, if fl exible connec-
tors are fi tted on the inlet side to minimize vibration
transmission, these should be taught and not encroach
into airstream to disrupt airfl ow.
• The unit shall be installed so that any prevailing winds
will blow against the opening motion.
Safe commissioning
• Installer to ensure safe to start fan and commission,
which may include determination of installed air duty
and system pressure if the fan inlet is connected to
ductwork.
Safe maintenance
• The user is responsible for effective maintenance, re-
placement of parts, cleaning, especially where dust
may form inside the fan.
• Do not remove safety protection guards or open access
doors when fan is in operation, or if hazardous substance
is present. Fan equipment should be electrically isolated
and locked out before any access or work is started.
• Refer to specifi c motor Instructions for further guidance.
Support
• If there is any problem with this unit contact your local
S&P Distributor. S&P reserve the right to make modifi -
cations without prior notice.
Safety risks – summary list
• Installation: incorrect installation or function repre-
sents a risk to safety.
• Rotational speed: identifi ed on fan name plate and mo-
tor. Never exceed this speed.
• Rotation of impeller: identifi ed on fan with direction
arrows. Do not run impeller in reverse.
• Working temperature: identifi ed on fan nameplate and
motor for S1 duty cycle. Never exceed this range.
• Protection devices: These should always be operatio-
nal and never disconnected for S1 duty cycle.
• Electrical risks: motor name plate data should never
be exceeded, effective connection to earth, and all
checked regularly every 6 months.
• Power supply should be via a protected source to ena-
ble fan to run under emergency fi re smoke conditions,
Direct on line.
• Foreign bodies: ensure no risk from debris, or material
that could be drawn into fan.
1.3. TRANSPORT, LIFTING
Transport and lifting must be carried out by competent
personnel and in accordance with applicable Internatio-
nal, National and Local regulations.
When transporting this unit, recommend that:
• Fan equipment and packaging are protected from ad-
verse atmosphere, especially water, sand, dust, vibra-
tion and excessive temperature.
• The fan should be protected from any impact, or risk
of damage.
When lifting / moving this unit, recommend that:
• All identifi ed fan lifting points are used to support wei-
ght and ensure safe transport via hoists, sling, sprea-
der bar as appropriate, without damage. Follow lifting
diagram affi xed to the unit's side. Maximum included
angle of any support sling must not exceed 30°.
• All slings or lifting forks under the fan equipment are
safe, and spaced to avoid tipping or slipping or damage
to fan equipment.
• Any lifting equipment must be safe and of suitable ca-
pacity for weight and size, plus lift distance.
