heater, space heater, stove, etc., harmful gases will be generated.
Use 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.
When 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.
When 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.
