Daikin R410A Installation Manual page 3

Safety Precautions
• After connecting all wiring be sure to shape the cables so that they do not put undue stress on the electrical
covers, panels or terminals.
Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, fire or equipment damage.
• When installing or relocating the system, be sure to keep the refrigerant circuit free from all substances other than
the specified refrigerant (R410A), such as air.
(Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise which may result in rupture, resulting
in injury.)
• During pump-down, stop the compressor before removing the refrigerant piping.
If the compressor is still running and the shut-off valve is open during pump-down, air will be sucked in when the refrigerant piping is removed,
causing abnormally high pressure which could lead to equipment damage or and personal injury.
• During installation, attach the refrigerant piping securely before running the compressor.
If the refrigerant pipes are not attached and the shut-off valve is open when the compressor is run, air will be sucked in, causing abnormal
pressure in the refrigeration cycle, which may result in equipment damage and even injury.
• Install a leak circuit breaker, as required.
If a leak circuit breaker is not installed, electric shock may result.
• Be sure to install a ground fault circuit interrupter breaker.
Failure to install a ground fault circuit interrupter breaker may result in electrically shocks or personal injury.
• Establish drain piping according to the instructions of this manual.
Inadequate piping may cause water damage.
• Note for installing the outdoor unit. (For heat pump model only.)
In regions of the country where the outside temperature is at or below the freezing point, the drain may freeze. If so, it is recommended that an
electric heater be installed in order to protect the drain from freezing.
• Tighten the flare nut according to the specified torque. A torque wrench should be used.
If the flare nut is tightened too much, the flare nut may crack over time and cause refrigerant leakage.
• Do not touch the heat exchanger fins.
Improper handling may result in injury.
• Be very careful about product transportation.
Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous.
