refrigerant leaks, degradation of performance, or any other potential
problems or damages as a result of interconnecting piping, their joint
connections, isolation valves, introduced debris inside the piping system,
or other problems caused by the interconnecting piping system.
Do not install the product where it is exposed directly to

When installing the outdoor unit in a low-lying area, or a lo-
cation that is not level, use a raised concrete pad or concrete
blocks to provide a solid, level foundation.
This prevents water damage and 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.
Always check for system refrigerant leaks after the unit has
been installed or serviced.

unit.
There is a risk of product failure.
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.
Keep the unit upright during installation to avoid vibration or
water leakage.
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 or BD unit in a noise-sen-
sitive 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.
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 a risk of unit and property damage.
Install the drain hose to ensure adequate drainage.
There is a risk of water leakage and property damage.
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.
