SAFETY INSTRUCTIONS
INSTALLATION - CONTINUED
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 person-
al injuries or death from oxygen depletion.
Be very careful when transporting the product.
• Do not attempt to carry the product without assistance.
• Some products use polypropylene bands for packaging.
• Suspend the unit from the base at specified positions.
• Support the unit a minimum of four points to avoid slippage from rigging apparatus.
Don't install the unit where it's directly exposed to ocean
winds.
Ocean winds may cause corrosion, particularly on the condenser and
evaporator fins, which, in turn could cause product malfunction or ineffi-
cient performance.
When installing the unit in a low-lying area, or a location that
is not level, use a raised concrete pad or concrete blocks to
provide a solid, level foundation.
This may prevent water damage and reduce abnormal vibration.
Properly insulate all cold surfaces to prevent "sweating."
Cold surfaces such as uninsulated piping can generate condensate that
may drip and cause a slippery surface condition and/or water damage to
walls.
When installing the unit in a hospital, mechanical room, or
similar electromagnetic field (EMF) sensitive environment,
provide sufficient protection against electrical noise.
Inverter equipment, power generators, high-frequency medical equip-
ment, or radio communication equipment may cause the air conditioner to
operate improperly. The unit may 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
preserving foods, works of art, wine coolers, or other
precision air conditioning applications. The 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 be damaged.
Keep the unit upright during installation to avoid vibration or
water leakage.

Do not use polypropylene bands to lift the unit.
Due to our policy of continuous product innovation, some specifications may change without notification.

Install the unit in a safe location where nobody can step on or
fall onto it.
There is risk of physical injury or death.
Properly insulate all cold surfaces to prevent "sweating."
Cold surfaces such as uninsulated piping can generate condensate
that could drip, causing a slippery surface that creates a risk of slipping,
falling, and personal injury.
Do not install the unit in a noise sensitive area.
When connecting refrigerant tubing, remember to allow for
pipe expansion.
Improper piping may cause refrigerant leaks and system malfunction.
Take appropriate actions at the end of HVAC equipment life
to recover, recycle, reclaim or destroy R410A refrigerant
according to applicable U.S. Environmental Protection
Agency (EPA) rules.
Periodically check that the outdoor frame is not damaged.
There is a risk of equipment damage.
Install the unit in a safe location where nobody can step on or
fall onto it. Do not install the unit on a defective stand.
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.
Don't store or use flammable gas / combustibles near the
unit.
There is risk of product failure.
Always check for system refrigerant leaks after the unit has
been installed or serviced.
Low refrigerant levels may 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 system
and authorization to do so has been obtained from the com-
missioning 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.
