11. VENTS MAINTENANCE
The devices must be installed in observance of all the necessary SHE principles,
particularly those related with working at height and using adequate personal protective
equipment.
Periodical maintenance works and service inspections are required on the installed
devices. These are performed by MERCOR S.A. authorized service. The service interval is
6 months. The following actions are required from the user between inspections.
1. Checking the condition of electrical connections, particularly checking for
mechanical damage.
2. Checking the condition of pneumatic connections, particularly checking for
mechanical damage.
3. Checking hook consoles (to see if they are completely shut and not blocked).
4. Check that the pressure frame holding the vent glazing is securely fixed; in case of
loosening, proceed as shown on point 10.
5. For vents with mechanical control, check that the cord opening the lock is not
tangled and moves without additional resistance. Check proper operation of the
lock. In case of its fault, proceed with the adjustments described in point 8.4.3
6. Periodical cleaning of the surfaces of domes/polycarbonate panels:
use sponge or soft fabric and lukewarm water with a mild cleaning detergent for
general household use. The panels must not be scrubbed with brushes and
sharp items. Do not use abrasive, strongly alkaline agents or solvents. In doubt,
test the cleaning agent on a sample or small area.
7. Due to natural processes taking place in the polycarbonate panel chambers, water
condensation may be observed. The most frequent symptom of this is occurrence
of mist, or - in case of high humidity - visible drops. If diffusion-based air exchange
is ensured between the air inside the chambers and the ambient air, humidity levels
in both areas will equalize in time, and the above mentioned visual effects will
disappear.
Condensation does not affect the material's life or quality of the product.
NOTE
It is prohibited to use salt for snow fighting works on roofs with mcr-PROLIGHT
vents installed - it causes risk of discoloration and damage to the aluminium
profiles, polycarbonate panels of acrylic domes. Any damages to the vents caused
by failure to observe the above instructions are not subject to warranty or other
claims.
