SAFETY INSTRUCTIONS
INSTALLATION - CONTINUED
Properly insulate all cold surfaces to prevent “sweating.”
Cold surfaces such as un-insulated piping can generate condensate that will
drip and cause a slippery surface condition and/or water damage to walls.
When installing the unit in a hospital, mechanical room, or

SURYLGHVXႈFLHQWSURWHFWLRQDJDLQVWHOHFWULFDOQRLVH
Inverter equipment, power generators, high-frequency medical equipment,
or radio communication equipment will cause the air conditioner to operate
improperly. The unit will also affect such equipment by creating electrical
noise that disturbs medical treatment or image broadcasting.
Do not use the product for special purposes such as pre-
serving foods, works of art, wine coolers, or other precision
air conditioning applications. This equipment is designed to
provide comfort cooling and heating.
There is risk of property damage.
Do not make refrigerant substitutions. Use R410A only.
If a different refrigerant is used, or air mixes with original refrigerant, the
unit will malfunction and become damaged.
Do not install the unit in a noise sensitive area.
When connecting refrigerant tubing, remember to allow for
pipe expansion.
Improper piping will cause refrigerant leaks and system malfunction.

There is risk of product failure.
Take appropriate actions at the end of HVAC equipment life
to recover, recycle, reclaim or destroy R410A refrigerant ac-
cording to applicable U.S. Environmental Protection Agency
(EPA) rules.
Periodically check that the outdoor unit is not damaged.
There is a risk of equipment damage.
Install the unit in a safe location where no one can step on or
fall onto it.
Do not install the unit with defective hanging,
attaching, or mounting hardware.
There is risk of unit and property damage.
Install the drain hose to ensure adequate drainage.
There is a risk of water leakage and property damage.
Always check for system refrigerant leaks after the unit has
been installed or serviced.
Low refrigerant levels will cause product failure.
The unit is shipped with refrigerant and the service valves
closed.
Do not open service valves on the unit until all
non-condensibles have been removed from the piping sys-
tem and authorization to do so has been obtained from the
commissioning agent.
There is a risk of refrigerant contamination, refrigerant loss and equip-
ment damage.
Do not run the compressor with the service valves closed.
There is a risk of equipment damage.
If the air conditioner is installed in a small space, take
measures to prevent the refrigerant concentration from
exceeding safety limits in the event of a refrigerant leak.
Consult the latest edition of ASHRAE (American Society of Heating,
Refrigerating, and Air Conditioning Engineers) Standard 15. If the
refrigerant leaks and safety limits are exceeded, it could result in per-
sonal injuries or death from oxygen depletion.
Properly insulate all cold surfaces to prevent “sweating.”
Cold surfaces such as un-insulated piping can generate condensate
that could drip, causing a slippery surface that creates a risk of slipping,
falling, and personal injury.
WARNING
CAUTION
Be very careful when transporting the product. Failure to follow these directions will result in minor or moderate physical injury.
• Do not attempt to carry the product without assistance.
• Some products use polypropylene bands for packaging. Do not use polypropylene bands to lift the unit.
• Suspend the unit from the base at specified positions.
• Support the unit a minimum of four points to avoid slippage from rigging apparatus.
