WARNING: PERSONAL INJURY/ENVIRONMENTAL HAZARD

Any attempt to repair a central air conditioning product may
result in property damage, severe personal injury, or death.
These units use R-410A refrigerant which operates at
50 to 70% higher pressures than R-22. Use only R-410A
approved service equipment. Refrigerant cylinders are
painted a "Rose" color to indicate the type of refrigerant
and may contain a "dip" tube to allow for charging of liquid
refrigerant into the system. All R-410A systems with variable
speed compressors use a POE oil (VG74 or equivalent )
that readily absorbs moisture from the atmosphere. To
limit this 'hygroscopic" action, the system should remain
sealed whenever possible. If a system has been open to
the atmosphere for more than 4 hours, the compressor oil
must be replaced. Never break a vacuum with air and always
change the driers when opening the system for component
replacement.
CAUTION: HOT SURFACE

Do not touch top of compressor. May cause minor to
severe burning. Failure to follow this Caution could result in
property damage or personal injury.
CAUTION: HIGH PRESSURE

Failure to follow proper procedures can result in personal
illness or injury or severe equipment damage.System

refrigerant to relieve pressure before opening system.

grounding devices. All parts of this product that are capable
of conducting electrical current are grounded. If grounding
wires, screws, straps, clips, nuts, or washers used to
complete a path to ground are removed for service, they
must be returned to their original position and properly
fastened.
