Slab Mounting - Lennox Elite EL22XPV Series Installation Instructions Manual

WARNING
To prevent personal injury, as well as damage to panels,
unit or structure, observe the following:
While installing or servicing this unit, carefully stow all
removed panels so that the panels will not cause injury
to personnel, objects or nearby structures. Also, take
care to store panels where they will not be subject to
damage (e.g., being bent or scratched).
While handling or stowing the panels, consider any
weather conditions (especially wind) that may cause
panels to be blown around and damaged.
IMPORTANT
Exhaust vents from dryers, water heaters and furnaces
should be directed away from the outdoor unit. Prolonged
exposure to exhaust gases and the chemicals contained
within them may cause condensation to form on the steel
cabinet and other metal components of the outdoor unit.
This will diminish unit performance and longevity
PLACEMENT
INSTALL UNIT AWAY FROM WINDOWS.
TWO 90° ELBOWS INSTALLED IN LINE SET
