2. Using aNSHEV
2.1 How itworks
Air moves through an open NSHEV as a result of the pressure difference between the inside and the outside of the
building. This pressure difference is a result of thermal buoyancy, convection, wind pressure or mechanical ventilation.
The direction of the airflowandalso its speed depends onthe prevailing conditions and can change while the NSHEV is being
used.
2.2 Smoke control ventilation
Opening and closing with M1B24 –electric control channel
The flap is moved by one 24 V DC electric actuator. The flap moves to its open position, opening angle ~140°. The flap is closed
using a 24 V DC electric actuator.
2.3 Day-to-dayventilation
Day-to-day ventilation with M1B24–electric control channel
The electric actuator used for day-to-day ventilation is identical to the electric actuator for the smoke control function,
the flap will open completely to its SHEV position of 140°. In this instance it is recommended that the ventilator is not
opened for day to day ventilation in high winds, otherwise damage to the unit may occur. Further, without a rain sensor
override, rain entry may occur if the ventilator is left open.
2.4 Acceptableapplications
The NSHEV is suited as a roof ventilator for industrial, commercial, residential and public buildings to provide:
• Smoke control and exhaust ventilation.
• Day-to-day ventilation. Not in high winds or without rain sensor.
• Providing an access route from inside the building to the roof.
• Allowing the movement of building components, machines or similar objects onto or off from the roof, within size
limits.
• Daylight entry with polycarbonate lid option.

2.5 Improper use
Such NSHEV may only be used in the manner described on these pages. In particular they are:
• Not suitable for use in places where there is likely to be an explosion.
• Not suitable for use in extreme conditions (for instance where there is high condensation, very high temperature
or corrosive substances within the air stream).
• Not suited to being walked upon.
• The maximum installation height depends on local wind load conditions. For further information, please contact
your Colt representative.
3. Essential safety information
Itisessentialto takenoteofthese basic warning signs. There are additional warnings given within other pages of thismanual.
󱛻󱛼󱛽 WARNING
Danger of flaps breaking when they are trodden upon
• Do not walk on a NSHEV since the flaps are not designed for such loads and can
break.The dangerofthis canariseparticularlyif therehasbeensnoworiftheNSHEV
isvery dirty orif the visibility is poor and as a result the safety labels are not clearly
visible. If someone falls through the unit, this can lead to injury or death as well as
damage to property
• It is important to inform all those who have access to the roof about the danger
of falling through such a unit, particularly when it is snowing, when the roof is dirty
orwhenvisibility is poor.
󱛻󱛼󱛽 WARNING
Injury as a result of the height of the installed ventilators
• Persons working on the unit at height need to avoid the possibility of tools or unit
components dropping. If this is not observed, there can be fatal consequences.
Those working at height should always observe all applicable health and safety
regulations. Those who are installing or working on a NSHEV need to be qualified
and trainedsuitably.
• The optional associated components are not stable enough to be used as
positions to fix safety harnesses to, which would have the purpose of stopping
people from falling off buildings. If this is not observed, there can be fatal
consequences.
󱛻󱛼󱛽 WARNING
Risks related to unsuitable positioning of the ventilator
• Ifit isinstalledonto anunsuitable roof there isa riskof collapse caused byitsweight,
among other things. If this is not observed, there can befatal consequences. Before
installation the engineering calculations must be checked in accordance with
applicable rules, to check whether the roof is suitable for installation of theNSHEV.
• A NSHEV is designed for extract ventilation and may not to be used for inlet air unless
the ventilator position and operation are considered carefully. Polluted air or exhaust
gas can harm people within the building.

󱛻󱛼󱛽 WARNING
Risk of smoke not being vented from the building
If the unit is not appropriately installed or commissioned, it is possible that the
NSHEV will not function as a smoke ventilator in the case of fire. This can lead
to damage, injury or death.
Such NSHEV need to be installed by trained personnel and commissioned
appropriately. If there are any malfunctions or if people are working on the
NSHEV, appropriate measures need to be taken to remedy them. The NSHEV
must be regularly inspected, maintained and if necessary, repaired.
󱛻󱛼󱛽 CAUTION
Unexpected opening or closing of the flaps
• It is possible to trap a part of the body between the flap if it opens or closes unexpectedly
whilst working on a NSHEV.
• When working on a NSHEV it is necessary to ensure that the control system cannot be
accessed and the ventilator cannot be opened or closed in an unexpected manner. It is
also important to keep in mind that the smoke exhaust and ventilation control function
canopen theunitunexpectedly.ThosewhoareinstallingorworkingonaNSHEVneedtobe
qualified and trained suitably.
󱛻󱛼󱛽 CAUTION
Damage as a result of rain ingress through open flaps or damaged
seals
• If a ventilator is left open when it rains or if seals are damaged, water can enter the
building and can damage the ventilator mechanism. Water can result in damage
to property or injury to persons.
• Clear any water and check if the flap closes correctly when there is rainfall.
Damaged seals or flaps need to be replaced in a timely fashion.
󱛻󱛼󱛽 CAUTION
Danger as a result of high weight
• The product identification (PID) label shows the unit's weight. The PID label is affixed
to the outside of the unit.
• The unit’s weight can lead to injury or damage if the unit is not correctly handled.
• Iftheunitismovedmanually sufficientnumbersofpeoplemustbeavailable.Thereis
Health and Safety guidance which provides information on the correct handling,
lifting and carrying of heavyweights.
