10. 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 the condition of gaskets.
5. For vents with mechanical control, check that the cords opening the locks are not
tangled, and move without additional resistance. Confirm proper operation of the lock.
In case of their improper operation, perform the adjustment actions 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. Check that the clamping frame holding the leaf glazing is securely fixed. If the
clamping frame loosens, loosen M6x30 screws slightly, and then screw them in
consecutively, simultaneously pressing on the frame and the glazing downwards.
8. 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 roofs with mcr-PROLIGHT vents installed -
it causes risk of discoloration and damage to the aluminium profiles and
polycarbonate panels. Any damages to the vents caused by failure to observe the
above instructions are not subject to warranty or other claims.
