NNUse appropriate tools and piping materials for installation.

The pressure of R410A is 1.6 times higher than R22. Not using the appropriate tools and materials, or improper installation could cause the pipes to burst causing

an injury.

NNWhen pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes.

If the refrigerant pipes are disconnected while the compressor is running and the stop valve is open, air could be drawn in and the pressure in the refrigeration cycle

could become abnormally high, causing the pipes to burst.

NNWhen installing the unit, securely connect the refrigerant pipes before starting the compressor.

If the compressor is started before the refrigerant pipes are connected and the stop valve is open, air could be drawn in and the pressure in the refrigeration cycle

could become abnormally high, causing the pipes to burst.
