• Before working at heights, put a sign in place so that no-one will approach the work location,
before proceeding with the work. Parts and other objects may fall from above, possibly
injuring a person below. While carrying out the work, wear a helmet for protection from falling
objects.
• The refrigerant used by this Dx-coil interface is the R410A.
