YORK
Model UQ units are factory assembled heat pump
designed to be installed along side the home or building. Field-
installed electric heater accessories are available to provide
supplemental electric heat.
The units are completely assembled on rigid 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 electric heaters have nickel-chrome resistance wire
elements and utilize single point power connection.
Safety Considerations
This is a safety alert symbol
labels or in manuals, be alert to the potential for personal injury.
Understand and pay particular attention the signal words
DANGER, WARNING or CAUTION.
