CAUTION
For proper work of the device with the limit switches, it is recommended that the rated voltage
housed tolerance of 24V±2% or 230V±2%. Power supply devices other than listed above may
cause malfunction and will not be covered by the warranty conditions.
In the case of damper working in particularly difficult conditions once every 3 months, a review should be
carried out including cleaning the electromagnetic surface and checking the confidence in hold.
7. TRANSPORT & STORAGE CONDITIONS
Fire dampers are packaged in cardboard boxes or placed on pallets. Dampers are protected against
damage by film or another covering material. Damper transport may take place using any means of
transport, provided they are protected against weather factors. Dampers placed on means of transport
should be secured against shifting of position during transport. Before installing dampers, control each of
them visually. Do not move the damper by holding by the connection cable or put a device on a release
and control mechanism. Do not hit or drop the damper. When moving and installing, support the damper
on the sides or edges of the body.
Dampers should be stored in closed rooms that provide protection against external weather conditions. In
the case dampers are stored on the ground, place them on protection pads in order to protect them against
damage. Storage should take place in rooms where:
• there is no access to dust, gases, caustic vapors and other aggressive chemical vapors that can
destroy insulating elements and structural elements;
• the dampers are not affected by direct sunlight and UV radiation;
• maximum relative humidity does not exceed 80% at the temperature of + 20 ºC;
• the ambient temperature is between - 20 ºC and + 40 ºC;
• there are no vibrations.
8. MAINTENANCE AND SERVICING
The equipment from Mercor SA requires periodic technical inspection and maintenance at least every 12
months throughout its operating life, i.e. during the warranty and post-warranty period. Inspection and
maintenance may only be carried out by the manufacturer or contractors authorised by MERCOR SA to
service its products.
Regular service inspections of fire protection equipment is mandatory in Poland according to § 3 Section

protection of buildings, other structures and areas (Polish Journal of Laws, Year 2010, No. 109 Item 719).
Do these recommended actions in the inspection intervals:
Check the electrical connections, especially for all mechanical damage.
Inspections of the condition of the supply voltage for the devices, which allowed the following
tolerances:
24V±10% for electric actuators
24V±2% for electromagnetic release mechanism
230V ±10% for electric actuators
230V±2% for electromagnetic release mechanism
Check the equipment casing, especially for all mechanical damage.
Check for any obstructions to proper performance of the equipment.
To facilitate the activities under service inspection, servicing and warranty claim response, e.g. visual
inspection or repairs, the equipment user/operator shall provide physical access to the equipment by
removing thermal insulation, suspended ceiling, and other installations, as required and applicable to
warrant unobstructed access.
Inspection ports, e.g. type mcr KRW are recommended for equipment installed in ducts.
In the case of roof mounted equipment, provide access to the area (via ladders or elevated platforms).
