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.

NOTICE !

Roof Damage!
This system contains both refrigerant and oil. Some
rubber roofing material may absorb oil, causing the
rubber to degrade. Failure to follow this notice could
result in damage to roof surface.

IMPORTANT !

Exhaust vents from dryers, water heaters and fur­
naces should be directed away from the outdoor unit.
Prolonged exposure to exhaust gases and the chemi­
cals contained within them may cause condensation
to form on the steel cabinet and other metal compo­
nents of the outdoor unit. This will diminish unit per­
formance and longevity.

STEP 2 -- REFRIGERANT PIPING -- Flush­
ing Existing Line Set and Indoor Coil 

Flush the existing line set per the following
instructions. CAUTION - DO NOT attempt to flush and
re-use existing line sets or indoor coil when the
system contains

 

contaminants (i.e., compressor burn

out).

IMPORTANT !

If this unit is being matched with an approved line
set or indoor unit coil that was previously charged
with mineral oil, or if it is being matched with a coil
which was manufactured before January of 1999,
the coil and line set must be flushed prior to installa­
tion. Take care to empty all existing traps. Polyol es­
ter (POE) oils are used in units charged with
HFC-410A refrigerant. Residual mineral oil can act
as an insulator, preventing proper heat transfer. It
can also clog the expansion device and reduce sys­
tem performance and capacity.

WARNING

Fire, Explosion and Personal Safety
Hazard. Failure to follow this warning
could result in damage, personal injury or
death.
Never use oxygen to pressurize or purge
refrigeration lines. Oxygen, when ex­
posed to a spark or open flame, can
cause fire and/or an explosion, that could
result in property damage, personal inju­
ry or death.
