MPS 3 System – Troubleshooting
11.4.5.Delivery Temperature Reads More Than 5° Above Water
Temperature
•
It is likely that the IR temperature sensor behind the heat exchanger has a dirty
lens. Clean the lens with water and a soft cloth.
•
If wiping the sensor does not fix the issue, ensure that there is not a heat source
pointed at the HEX or making contact with it.
11.4.6.Delivery/Vent Valves Errors
•
The antegrade, retrograde, or vent valve may have debris or buildup in the
mechanism. Rinse the valve with warm water and actuate the valve manually
several times to clear the debris.
11.4.7.Low/No Water Flow in Circulation System
•
The circulation system may not be primed properly.
•
If using Hypothermic Reservoir:
o Ensure the Hypothermic Reservoir has water filled to the drain
port.
o Elevate the Hypothermic Reservoir above the MPS 3 System so
that the outlet port of the reservoir is above the heat exchanger.
o Check the water lines to ensure they are properly connected to
the correct inlet and outlet ports
o Check the water lines to ensure they are not kinked or blocked.
o Try to prime the circulation system using the H2O Prime
function.
•
If using Heater Cooler:
o Ensure the heater cooler unit is properly filled with water and
primed per manufacturer recommendations
o Check the water lines to ensure they are properly connected to
the correct inlet and outlet ports
o Check the water lines to ensure they are not kinked or blocked.
o Ensure the heater-cooler is in the correct mode and able to flow
properly.
•
If Circulation system is having trouble priming due to excessive air, unlock heat
exchanger and insert one prong of the hemostat into HEX port to remove air
locked in Circulation system.
11.4.8.Cannot Close the Door
• If the door is opened while the delivery set is primed, blood will fill the cassette
and make it difficult to close the door. To close the door, clamp the source lines,
manually open the vent valve and depress both cassette chambers until most of
the fluid is evacuated. Release the vent valve and close the door.
11.4.9.Cannot Install Heat Exchanger
•
Refer to section 8.1.1 for full details on installation of the heat exchanger.
•
Verify that the locking knob is fully unlocked by rotating it counterclockwise
(CCW).
