SAFETY CONSIDERATIONS
Due to system pressure, moving parts and electrical components,
installation and servicing of air conditioning equipment can be hazardous.
Only qualified, trained, service personnel should install, repair, maintain
or service this equipment.
Observe all precautions in the literature, on labels and tags
accompanying the equipment whenever working on air conditioning
equipment. Be sure to follow all other safety precautions that apply.
Wear safety glasses and work gloves, and follow all safety
codes. Use a quenching cloth and have a fire extinguisher
available for all brazing operations.
GENERAL
Model BDF Dual Fuel Heat Pumps are single package units with gas
heat designed for outdoor installation on a rooftop or a slab.
The units are completely assembled on rigid, permanently
attached base rails. All piping, refrigerant charge, and electrical
wiring is factory installed and tested. The units require only
electric power and duct connections at the point of installation.
The gas-fired heaters have aluminized steel tubular heat
exchangers and spark ignition with proven pilot.
INSPECTION
As soon as a unit is received, it should be inspected for possible
damage during transit. If damage is evident, the extent of the
FOR YOUR SAFETY
