The centrifugal fan runs at two speeds:
·
Low speed provides normal steam exhaust. (It works similar to the
auto steam exhaust [ASE] feature).
·
High speed minimizes steam leakage from the cabinet during HABO.
Refer to the vendor-supplied cutsheet for instructions on setting fan speed.
Controlling HABO Heat
Thermocouples in the outside plenum on top of the washer cabinet and a temperature
controller inside the electrical control panel control HABO heat.
NOTE : The outside plenum contains the blower unit, the thermocouples, and the
heating element.
A redundant (back-up) heat-source measuring system works in conjunction with a high-
level shutdown system to de-activate the HABO system if the heating element should
overheat. Refer to section
"Troubleshooting."
9.2. Installation
If you have a HABO system, you must modify standard ASE installation procedures.
Refer to the following figures.
MART has available as an option flanged transition pieces to adapt the ASE fan to
round ducting.
To install the HABO , follow these guidelines :
1. There are two couplings welded into the ASE fan blade housing. Use one of
these couplings to connect a drain line back into the ASE ducting below the
fan. This will allow condensed water vapor to drain back to the washer.
2. The output of the ASE fan can be rotated to any direction. Select a direction
for the output that puts one of the two drain couplings on the fan in the
DOWN position.
3. Remove the fan housing and rotate it to the selected direction.
