WARNING
"Polyolester Oil, commonly known as POE oil, is synthetic oil
used in many refrigeration systems. POE oil, if ever in contact
with PVC/CPVC, will coat the inside wall of PVC/CPVC pipe
causing environmental stress fractures.
Although there is no PVC/CPVC piping in this product, please
keep this in mind when selecting piping materials for your
application, as system failure and property damage could result."

Uncrate and Inspect the Unit Ventilator(s)

to provide jobsite unit location information and temporary protection
for the unit ventilator after installation.) Be sure to dispose of plastic
packaging and protective cardboard properly, in accordance with local
recycling rules and guidelines.
If unit is damaged, file a claim with the carrier. Notify the local AAF
HermanNelson Unit Ventilator representative immediately.
Prior to unit installation, be sure that the exterior wall openings and
