Upon receipt of unit - Before signing for the delivery
Flourescent yellow stickers are attached to every package we
despatch detailing receipt instructions and what to do if your goods
are damaged.
The instructions on this must be followed or HVC will not be able to
assist with any claims for damage.
Prior to installation
If the damper is to be stored on site, ensure it is stored in a clean
and dry environment.
Immediately prior to fitment, remove all packaging from the unit.
Take particular care inspecting the inside of the unit for any
packing materials which may disrupt damper operation.
Installation
All fire damper installations must be carried out as stated by HVC.
Installation instructions are available to download at:
www.h-v-c.com/installations
Installation should only be carried out by competent persons. Fire
dampers are life safety devices, their effectiveness is reliant on
correct installation.
Damper edges can be sharp. The relevant PPE should be used
when handling dampers, in accordance with the relevant local risk
assessment/s.
Larger dampers can be very heavy, ensure suitable lifting methods
are used to help prevent injury.
Ensure that ductwork is appropriately supported, and that the
damper itself will not be relied upon to support ductwork.
Remove the safety cable tie from the fusible link. Failure to remove
this will render the damper inoperable.
Installation should always take into account the requirement to
provide future access for testing and maintenance, by fitting
appropriately positioned and sized access doors.

Operation
Fusible link fire dampers are passive devices, and are designed to
operate without any command from an operator or system.
Fusible links will split, closing the damper when the temperature
inside the duct reaches that embossed on the link body.
The use of electromagnets or solenoids enables the damper to be
closed remotely, however they will still close when the link’s rated
temperature is reached.
Once the damper has been shut, it can only be reset manually.
Once a fusible link has split, it must be replaced with a new unit.
Spares
An amount of spare fusible links should be kept on site.
Thank you for purchasing an NCA Series 100 fire damper.
Please ensure the following information is read, understood and
followed at all stages of the damper’s life.
