I. RECEIVING INSTRUCTIONS
Make-up Air Units with multiple furnaces are shipped
in sections. Each section has a label with Order no.,
Model No., Unit No., and Part No. marked on it. Make
certian that the order, model, and part numbers agree
on each section to be connected together.
Inspect shipment immediately when received to
determine if any damage has occurred to the crate
during shipment.
After the unit has been uncrated, check for any visible damage
to the unit. Check motor position and turn blower wheel to
