Care Of Sweden Mattress System CuroCell Cirrus

Connect the pump to the testing equipment according to fig 2.6. Make sure all air connections are secure.

Pump started and finished the start-up procedure

Indicator changed from Autofirm to Alternate

Checklist for incorrect pressure range

CAUTION when working with the pump when the power is on.

Air leak detected from timing motor?

Leaks found from air tubing? (Pump exploded view diagram, fig 3.1)

Assure the voltage supplied from power cord is correct

Switch on the power. The normal power supply light will be illuminated

Press the comfort left/right selection button, and the power button together for 5 seconds, to enter in the calibration procedure

When in the calibration procedure, the On/Off LED will be lit, while the remaining LED lights should not be lit. The compressor will not function as the timing motor is in the repositioning process

When the timing motor repositioning process is finished, the low pressure LED will start flashing. The compressor will start to work and the calibration can begin

Make sure the pump air let is not obstructed, and that the air output is normal

Press the alarm mute button, the low pressure LED will turn off. The LED lights of Comfort 1 and Comfort 2 will light up and flash, and the compressor will stop working. The first part of the calibration is now finished, and the pump is ready to perform the low pressure calibration

Provide a stable 15 mmHg pressure

Press the Alarm mute button, the LED lights of Comfort 1 and Comfort 2 will turn off. After that, the LED lights of Comfort 9 and Comfort 10 will light up and flash, and the compressor will stop working. The low pressure calibration is finished, and the pump is ready to perform the high pressure calibration

Fasten or replace with new timing motor or compressor:

1. Assure the voltage supplied is correct.

2. Check the pump according to the steps in section 2.3.4, if problem encountered isn’t included perform the following check.

3. Check the timing motor functions well, if not, perform step 5 and 6 to replace components.

4. Check the compressor is well functioning, if not, perform step 7 and 8 to replace components.

5. Disconnect the wires to the timing motor and the micro switch from the PCB.

6. Use a screwdriver to loosen 2 screws that secure the timing motor.

7. Replace with a new timing motor according to the part number listed from the BOM, then fasten the screws and wires.

8. Disconnect the wires to the compressor from the PCB using longnosed pliars, pull loose the 4 rubber dampers from the compressor mounting plate.

Upload a photo of the fuse in the holder before removal

Is the new fuse properly inserted and fastened?

Any visible damage inside the pump?

Upload a photo of the pump after fuse replacement

Is the pump functioning normally after fuse replacement?

Sign off on the fuse replacement

Warning: Ensure the device is powered off before starting the procedure

Disconnect all wire leads from the PCB

Loosen the air tube from the pressure sensor

Remove the 4 screws from the PCB

Enter the part no. listed from the BOM

Replace with a new PCB according to the part no.

Connect all wire lead connectors in the correct positions on the PCB

Connect the pressure sensor tube in the correct position on the PCB
