F1
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 HE1.5XRT 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.
Provide Adequate Service Access for Maintenance. The HE1.5XRT will require regular filter and core
inspections. Install the HE1.5XRT where you can open the doors for cleaning the core and replacing the
filters, and where you can get at the wiring for installation and service. Observe all safety precautions when
working on roofs, including locating the unit away from roof edges, provision of safety railings and use of fall
protection equipment.
CAUTION
CAUTION
Provide service access to the unit to allow for cleaning the core and filter.
