7. TRANSPORT AND 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.
8. MAINTENANCE AND SERVICE
„Mercor” SA devices should undergo periodical technical inspections and maintenance actions, no less frequent than
12 months during the entire operation period, that is during the warranty period and after it. Inspections and
maintenance should be carried out by the manufacturer or by companies that have authorisation for servicing of
„MERCOR” SA devices.
The obligation to carry our regular service inspections of fire protection devices results from the Art. 3(3) of the
Regulation by the Minister of Internal Affairs and Administration of 7 June 2010 on fire protection of buildings, other
civil structures and areas (Journal of Laws of 2010 No. 109, item 719).
It is recommended to execute, between inspections, the following:
Inspections of the condition of electrical conditions, taking the mechanical damage particularly into account.
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
