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.
Connect the stop valves to the field piping using the accessory pipes supplied with
the unit.
The connections to the branch kits are the responsibility of the installer (field
piping).
