SAFETY INSTRUCTIONS
INSTALLATION - CONTINUED
Replace all control box and panel covers.
If cover panels are not installed securely, dust, water and animals may
enter the outdoor unit, causing fire, electric shock, and physical injury or
death.
Always check for system refrigerant leaks after the unit has
been installed or serviced.
Exposure to high concentration levels of refrigerant gas may lead to
illness or death.
Be very careful when transporting the product.
Use appropriate moving equipment to transport each unit; ensure
the equipment is capable of supporting the unit's weight.
• Some products use polypropylene bands for packaging.
use the polypropylene bands to lift the unit because they will not support
the unit's weight.
• Suspend the outdoor unit from the base at specified positions.
Support the outdoor unit a minimum of four points to avoid slippage
from rigging apparatus.
Do not install the product where it is exposed to directly
to ocean winds.
Sea salt in the air may cause the product to corrode. Corrosion,
particularly on the condenser and evaporator fins, could cause product
malfunction or inefficient operation.
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 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 broad-
casting.
Do not use the product for mission critical or special pur-
pose applications such as preserving foods, works of art, or
other precision air conditioning applications. The equipment
is designed to provide comfort cooling and heating.
There is risk of property damage.

Periodically check that the outdoor frame is not damaged.
There is a risk of explosion, physical injury, or death.
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.
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.
When connecting refrigerant tubing, remember to allow for
pipe expansion.
Improper piping may cause refrigerant leaks and system malfunction.
Do not install the outdoor unit in a noise-sensitive area.
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
.
Do not store or use flammable gas/combustibles near the
unit.
There is a risk of product failure.
Install the drain hose to ensure adequate drainage.
There is a risk of water leakage and property damage.
