Perform the following Preventive Maintenance procedures every 12 months or 4000 hours of machine operation, whichever comes first.

Make copies of the Annual Preventive Maintenance Checklist provided at the back of this manual and use them to record the maintenance done.

Before starting the Annual Preventive Maintenance, select one of the following on Annual Preventive Maintenance Checklist:

Clean filters and replace O-rings as follows. Replace any filters that appear damaged or corroded.

Inlet Water Filter in the inlet connector of the water supply (See Figure 2, pg. 9).

Filters and O-rings in the concentrate (acid) and bicarbonate connectors (See Figure 4). Replace all three O-rings in each connector.

Clean the Dialysate Inline filter (See Figure 2, pg. 9).

Replace the O-rings in the Dialysate Line Connectors (See Figure 2, pg. 9).

Warning! The use of a 'test drip chamber' or 'dummy drip chamber' must never be used on the treatment floor. It must only be used in a controlled technical environment.

Place the dialysate lines in the shunt and close the door

Place a venous chamber filled with water in the holder on the level detector module

Place the machine in Dialyze mode and start the blood pump. Clear all blood and water alarms

Select the Test & Options button. On this screen select the Both Tests button. Press the [CONFIRM] key to start

Observe the machine stepping through the following alarm tests and ensure that each alarm produces all of the responses shown in Table 1

When the tests shown in Table 1 are complete, the machine conducts a pressure holding test. When the test ends verify that the display screen reports TEST COMPLETE, indicating that all the tests were passed successfully. Press the [RESET] key

Pull the hydraulic out and remove the output tube from the UF pump. Install a 24' tube (part number 545325-10) to the empty output port. Route this tubing out the back of the machine so that it will not be kinked or pinched when the hydraulics is closed. Close the hydraulics and place the other end of tube into a collection container
