The Fluid-o-Tech pump is no longer available, but units with this pump can be
retrofitted with the SciCan pump oNlY.

The SciCan pump and ulka pump are NoT interchangeable. They are both still
available. If replacing the pump during maintenance or servicing, the same pump must
be fitted to ensure the unit works correctly.
Testing pump flow (for all types)
To test a water pump, proceed as follows (see Figure 2):
The control box should be attached to the unit, or select ‘pump’ in the device test sub menu of the
revision 7.x controller board service menu (if cover is removed but still connected). The unit should
be powered on with the cassette removed.
1. Disconnect the Teflon™ steam generator inlet tube (1) from the top of the steam generator (2)
using a 3/8-inch wrench.
2. Connect the disconnected end of the steam generator inlet tube to the pump tester (3).
Do not
cross thread the fittings. Do not overtighten.
3. Using the button on the control box or appropriate keypad button (revision 7.x controllers),
activate the pump for 2 seconds to purge any air that is trapped in the fittings. Empty any
water that enters the pump tester. Recap the pump test bottle. The pump tester MUST be
empty before starting the pump test.
4. Be prepared to record the time it takes for the water level displayed on the pump tester to
reach the top of the line marked MIN (see below). Activate the pump.
5. If the water level reaches the top of the line marked MIN within the time allotted in the Pump
Flow Parameters chart (below), the pump is performing correctly.
