When removing a connector carefully NOTE its position and label. There are several unused (empty)
positions, AVOID them! Be VERY CAREFUL to return connectors to their correct positions!
If possible, unplug only one connector at a time
To prevent damage, turn the machine off BEFORE removing OR returning a RIBBON cable. These
include the sensor, actuator, acid and bicarbonate pumps, blood leak sensor and digital heparin
pump (if equipped). RULE! If it's a RIBBON cable don't unplug it with the machine on!
The 5-pin female connectors can be unplugged and returned with the power on
THE 8-PIN HEATER CONNECTOR PRESENTS AN ELECTROCUTION HAZARD. ALWAYS TURN
