4.1.3.3 Softer bearing (UC/11 and later)
Softer bearing (UC/11 and later) & non-softer bearing (UC/06)
heater assemblies, circulation pumps and sumps cannot be
mixed and matched. Softer bearing heaters don’t fit in older
models and older heaters don’t fit in softer bearing models.
Softer bearing & non-softer bearing heater assemblies are
connected to circulation pumps differently:
• Softer bearing models (UC/11 & above) have gasket
assembled to heater and have a separate hose clamp
(order # 172272).
• Older models (UC/06) have a separate gasket and do
not have a hose clamp.
4.1.3.4 Top Rack Only
Models with Top Rack Only have separate actuators mounted
underneath heater assemblies. The actuator moves a magnetic
float to block the lower rack port, diverting water to the top rack.

The actuator moves a magnet under the magnetic float so the
north poles align, repelling the magnetic float upward until it
blocks the water flow to the lower spray arm.
