XT SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
WIRING XT STEAM BLOWERS
Make the following wiring connections between the humidifi er and the XT
steam blower, and tighten all terminals securely:
Fuses provided. See page "XT steam blowers" on page 40.
Connect XT steam blower fan wires to humidifi er terminals 32, 33, and GRD.
Refer to the external connections diagram shipped with the XT steam blower.
PIPING CONDENSATE TO HUMIDIFIER FILL CUP
1. Remove fill cup cap from XT Series humidifier, and drill a 1/2" (13 mm)
hole in fill cup cap for SDU-006E and SDU-017E condensate hose as
shown in Figure 44-1.
2. Route XT steam blower 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
44-2. The water seal is required to ensure condensate drainage
from the XT steam blower and to keep steam from blowing out of the
condensate hose.
PIPING CONDENSATE TO DRAIN
The XT steam blower condensate hose must be routed as shown in Figure
44-2. The water seal is required to ensure condensate drainage from the XT
steam blower 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.
