WARNING
Provide adequate measures to prevent that the unit can be used as a shelter by small
animals. Small animals that make contact with electrical parts can cause
malfunctions, smoke or fire.
NOTICE
Make sure to open the stop valves after installing the refrigerant piping and
performing vacuum drying. Running the system with the stop valves closed may
break the compressor.
NOTICE
▪ Be sure to use the supplied accessory pipes when carrying out piping work in the
field.
▪ Be sure that the field installed piping does not touch other pipes, the bottom
panel or side panel. Especially for the bottom and side connection, be sure to
protect the piping with suitable insulation, to prevent it from coming into contact
with the casing.
