PLACEMENT OF THE HE2XRT
The HE2XRT is designed for installation on a roof or other outside location. Select a location that is central
to the inside duct runs, and close to any other air handler that might be part of the system.
PLANNING
YOUR INSTALLATION
INSTALLATION
It is the installer’s responsibility to make sure that
the screws or bolts used for securing the units
are properly selected for the loads and substrates
involved. Secure the HE2XRT so that it cannot fall
or tip in the event of accident, structural failure or
earthquake. See Rigging Information for unit weight.
RenewAire strongly recommends that you secure
rooftop units properly to the building structure.
Strong winds, tornados, and hurricanes can and do
displace or remove rooftop equipment from rails or
curbs. When this happens, the equipment, adjacent
roof structure, and even vehicles parked near the
building can be damaged, and rain typically enters
the building. The equipment is put out of service
and the collateral damage can be very expensive.
