VUT .. WH ЕС
Mount the unit on a rigid and stable structure. Check the technical parameters and the unit
weight.
Use bolts to suspend the unit to the ceiling. Make sure that the construction has sufficient load
capacity to carry the unit weight. Otherwise reinforce an installation place by beams etc. After that fix
the bolts. If the construction strength or surface is not rigid enough it can resonate with the unit and
create abnormal noise and vibration.
While mounting the unit provide enough service space and an access door in the ceiling for
inspection and maintenance of the filters, heat exchanger and fans. One access door is required for
each unit.
Make sure that the ambient conditions match the unit operation requirements before starting
any installation works.
The operating temperature for the unit ranges b1°C and +40°C for dry bulb thermometer
at relative humidity 80%.
If the bolts used for the unit mounting are too short the unit can generate abnormal noise and
resonate with the ceiling.
Use longer bolts with to prevent resonance.
Use longer bolts with to prevent resonance. If the connection point to the spiral seam duct is
supposed to be the source of the abnormal noise, install a flexible air duct instead of the flexible one.
For the better effect you may use anti-vibration connectors.
Make sure of no foreign objects inside the casing before installation. Preinstall M8 anchor bolt.
Then insert the anchor bolt inside the mount for the fixing bracket and fix it with nuts and washers.
While mounting the unit provide enough minimum distances for accessing the unit for its
servicing and maintenance. The minimum distance from the unit to the wall is shown in fig. 6.
