IMPORTANT SAFETY INFORMATION
CAUTION
It is highly recommended that you do not open or close
the stop valves when the outdoor temperature is below
-5°F (-21°C) as this may cause refrigerant leakage.
After a long period of disuse in an environment 32 °F (0° C)
or lower, supply power to the unit at least 12 hours before
re-starting the unit.
Do not touch the fins of the heat exchanger. Touching the
heat exchanger fins could result in damage to the fins or
personal injury such as skin rupture.
The power source capacity must be the sum of the air
conditioner current and the current of other electrical
appliances. When the current contracted capacity is
insufficient, change the contracted capacity.
When the voltage is low and it is difficult to start the air
conditioner, contact the power company to have the
voltage raised.
Be sure to install a breaker of the specified capacity.
Regulation of cables and breaker differs from each
locality, refer in accordance with local rules.
Do not use existing pipes.

Observe all governing
Use pipes that have clean external and intermal sides
without any contamination which may cause trouble
during use, such an sulphur, oxide, dust, cutting waste,
oil, or water.
It is necessary to use seamless copper pipes. Material:
Phosphor deoxidized seamless copper pipes. It is
desirable that the amount of residual oil is less than 40
mg/10 m.
Do not use copper pipes that have a collapsed, deformed,
or discolored portion (especially on the interior surface).
Otherwise, the expansion valve or capillary tube may
become blocked with contaminants.
Improper pipe selection will dearade performance. As an
air conditioner using R410A incurs pressure higher than
when using conventional refrigerant, it is necessary to
choose adequate materials.
To prevent breaking of the pipe, avoid sharp bends. Bend
the pipe with a radius of curvature of 4 in. (100 mm ) or
more.
If the pipe is bent repeatedly at the same place, it will
break.
CAUTION
• Aluminum building wiring may present special
problems - consult a qualified electrician.
• When the unit is in the STOP position, there is still
voltage to the electrical controls.
