2.1 LOCATING AND MOUNTING THE UNIT
When performing installation, servicing or cleaning the unit, it is recommended to wear safety glasses and gloves.
WARNING
!
These units can be installed upside down if needed.
• Once the unit has been properly suspended with the chains, if required, rotate both backdraft dampers to make
sure they are positioned in such a way that the word "TOP" is up and that gravity allows them to close properly.
• For HRV130FL units, if unit is installed in reversed position, remove the condensing plate from the core by
removing the core from the unit, and removing both screws holding the plate to the core.
