Models SD323-3B3:
The VRDXL used on the SD323-3B3 units is only available as a remote unit (wall mounting bracket supplied),
although it can be mounted on the wall directly over the humidifier unit if desired. (2 VRDXL units are required for
models SD360-384 and 3 are required for the SD3B3). Dimensions shown above.
1. Secure the VRDXL to the wall using
the wall mounting bracket supplied.
2. Connect steam and condensate
hoses to the bottom inlets and run to
the top of the humidifier unit. Run
wires from X1 and X2 in the VRDXL
into the humidifier’s electrical
compartment.
3. Connect the steam hoses to the top
of the cylinder outlet and secure them
with the supplied hose clamp. Run the
condensate hose to the unit drain pan
and lay it in the bottom so that it will
drain into the drain pan.
4. Connect the wires from X1 and X2
in the VRDXL to terminals X1 and X2
in the back of the humidifier unit.
