INSTALLATION
Maintenance
Unpack the unit.
To hoist the unit, secure using 4 slings attached to the
4 fitting hang tabs on the corners of the unit.
Mounting
The unit should be mounted on a completely flat
surface, using the side holes provided for this purpose.
We recommend securing the unit with anti-vibration
mountings and flexible connectors.
Allow clearance equal or greater than dimension C for
replacement of the filter.
Note: The unit can also be wall-mounted, in the
vertical position. All positions are possible
When fitting the unit to a ceiling, we recommend
previously installing the 4 cover tabs supplied with this
instruction leaflet for cover removal.
These enable the cover to be moved sideways to
have access to the filter. Then the filter can be
removed and replaced by a new one.
To remove the cover completely, just slide it off
sideways.
To fit the 4 cover tabs, unscrew the 8 sheet metal
screws fixed to the sides of the unit.
Screw them in again to secure the 4 cover tabs.
These 4 cover tabs allow the fitting screws to be
unscrewed from the cover without it falling.
