SAFETY INSTRUCTIONS
INSTALLATION - CONTINUED
Don’t install the unit where it’s directly exposed to ocean
winds.
Ocean winds may cause corrosion, particularly on the condenser and
evaporator ns, which, in turn could cause product malfunction or inef-
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 eld (EMF) sensitive environment,
provide sufcient 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 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.

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.

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.
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.
