■ DX Coil Schematic and coil preparation
Maximum real piping length between Dx-PMV kit and Dx-Coil is up to 16ft.
(Note) Be sure to connect piping in correct direction. On the bottom on base box, there is the label to indicate the direction
of inlet coming from outdoor unit and outlet to Dx-Coil.
The VRF Dx-PMV kit (RBM-A___1GUL) is necessary as separate products. These will need to be assembled and then fitted to
Dx-Coil. This is a custom process as each Dx-Coil will be different. Time and care should be given to this activity, and it should
be prepared off-site.
