Installation
Dispersion:
XT steam blowers
Wiring wall-mounted XTSB
Make the following wiring connections between the humidifier and
the XTSB, and tighten all terminals securely:
Connect humidifier terminals L1, L2, STM, C, and GRD to
matching XTSB terminals L1, L2, STM, C, and GRD.
Refer to the external connections diagram shipped with the XTSB.
Installing base plate
The XTSB has a base plate for wall-mounted XTSBs to isolate
the hot steam box from contact. After the electrical connections
are made, assemble the base plate onto the XTSB with the screws
provided.
Piping condensate to XT humidifier fill cup cap
1. Remove fill cup cap from XT humidifier, and drill a ½" (13 mm)
hole in fill cup cap for XTSB-20 and XTSB-50 condensate hose
as shown in Figure 43-1.
2. Route XTSB condensate hose through hole in fill cup cap, and
secure condensate hose in place.
Note: Make sure condensate hose has a water seal, as shown
in Figure 43-2. The water seal is required to ensure
condensate drainage from the XTSB and to keep steam
from blowing out of the condensate hose.
Piping condensate to drain
The XTSB condensate hose must be routed as shown in Figure
43-2. The water seal is required to ensure condensate drainage
from the XTSB and to keep steam from blowing out of the
condensate hose.
After the water seal, run the condensate hose to an open drain. Cut
the hose at a 45 degree angle on the end above the drain to permit a
direct stream of water into the drain while maintaining an air gap.
The condensate hose must be installed and sized according to
governing codes.
