2.- INSTALLATION
2.4.- UNIT LOCATION
The bedplate is made up of three galvanized metal channels, capable of withstanding the weight of the units whether hung from the
ceiling or mounted on the floor.
If the unit is floor mounted, then the profiles should be isolated with shock absorbing material such as anti-vibration or pads. Keep in
mind that fans rotate at approximately 850 rpm.
If the unit is hung, M-0 threaded rods should be used along with shock absorbing ceiling supports.

2.5.- INSTALLATION CLEARANCES
Clearance around the unit for service and maintenance
SERVICE SPACE
Space should be left free for access or servicing, to ease the installation of cables, drainage connections, electric installation and
cleaning filters, as well as easy access to the unit.
2.6.- DRAINS
All the indoor and outdoor sections of these units have a 3/4” steel threaded drain pipe welded to the condensation tray.
Drainage pipes will be fitted for each tray through a siphon with a height
difference of 80 mm. to avoid drainage problems from the depression formed
by the fans. The pipes should have an inclination of 2% to ease drainage of
condensation.
Also slightly tip the unit (2%) toward the drainage side. Check that the condensation
trays are clean and free from dirt and other debris from the works and that water
drains correctly.
