Electrical safety
Safety extra low voltage V DC!
Do not connect directly to the mains supply!
Connection has to be carried out only by an
authorized electrical specialist.
Actuator rating: IP Protected from limited
dust ingress. Not protected from liquids.
Actuator must be installed on the inside of the
building.
Other Risks
When the product is voltage fed, the ventilator
will be either open or close and there can be a
risk for pinch injuries, for example, on the ngers
if these are placed between the louvred blades.
Danger of crushing hands and ngers!
Initial Checks
Firstly, check the site and ensure that it is safe
and clear of obstacles or hazards before com-
mencing work. Inspect the work area again
checking for potential trip hazards. Ensure that
adequate edge protection is provided if working
from height.
A method statement and risk assessment should
be prepared before any work is carried out.
Suitable access equipment, scaolding or
MEWPs should be used if working at height. All
personnel should be suitably trained in their use.
If working in a high up location, ensure that
there are no walkways or footpaths below the
work area and that no one is working below.
This could put people at risk from falling debris.
Employ a marshal if necessary to keep people-
from going into the area below the work.
Ensure that the xing substrate is structurally
sound and capable of supporting the vent.
Ensure that it is also free of any potentially
hazardous material. Use a detector to ensure
there are no services such as electrical cables or
gas pipes that could pose a potential hazard.
Unloading
The weight of the goods should be assessed
before unloading. Unloading of goods should
be carried using suitable ooading equipment
if required. Manual handling should only be
employed if the weight of the goods is within
safe limitations and the right number of people
should carry out the li.
Goods should be stored in a safe storage area,
as near to the area of work as possible to avoid
unnecessary handling.
Liing and handling
As with ooading, appropriate liing equipment
should be used if required. If NSHEVs are to be
handled manually then the relevant number of
people should be employed for liing.
When NSHEVs have to be moved on site, louvres
must be closed. The NSHEVs can be stored
either on their ends or on their sides. Avoid
placing force on the corners. This may result in
mechanical failure.
Extra care should be taken when handling glass
and every precaution should be taken to avoid
breakages.
All liing should be carried out using best
practice. Suitable hop-ups or access equipment
should be used to avoid stretching or liing
overhead.
The HSE Work at Height Regulations should
be followed at all times.
Installation
Install the product for easy access during
service/maintenance.
Use appropriate tools and the recommended
xings – ensure that the vent is installed safely
and securely. Avoid long periods of drilling.
When opening and closing the NSHEV ensure
that hands are held away from any moving
parts to avoid the possibility of trapping/
crushing.
Once installed the NSHEV should be le in a
safe manner, ideally with the blades closed
ensuring that no parts of the NSHEV are
protruding into a walkway area.

Installation
Builders clear opening
Use the below graph to check the opening
sizes meet the minimum requirements
For the horizontal clearance apply the width
of the VENGEN28 NSHEV to obtain minimum
clearance values to be applied to each side of
the NSHEV.
For the vertical clearance apply the height of
the VENGEN28 NSHEV to obtain minimum
clearance values to be applied to the top &
bottom of the NSHEV.
Example:
Unit 1000 (W) x 1300 (H)
Horizontal Clearance : 9.7mm ----
Vertical Clearance : 12.5mm ----

Cleaning
External surface
Cleaning should start at the time the products
are installed, ensuring that construction
materials such as concrete, plaster and paint
splashes are removed before they have a
chance to dry. Failure to remove these materials
at this early stage will require the use of
aggressive cleaning materials and techniques
with potential damage to the powder coated
surface.
The best method of cleaning is by regular
washing of the coating using a solution of warm
water and non-abrasive, pH neutral detergent
solution. Surfaces should be thoroughly rinsed
aer cleaning to remove all residues. All surfaces
should be cleaned using a so cloth or sponge
or nothing harsher than a so natural bristle
brush. Cleaning of powder coated sections can
be conveniently carried out at the same time
as window cleaning. If the project is subject to
any hazardous unusual environmental factors,
or is close to salt water an estuary or marine
environments then swegon must be consulted
on an individual project basis.
The frequency of cleaning depends in part on
the standard of appearance that is required and
also the requirements to remove deposits, which
could cause damage. For frequency please refer
to Interpon D series Cleaning and Maintenance
Guidelines.
