Chapter 4 Operating instructions
FLUSHING PUMP OFP-2
36
NOTE
• It may be found that the pump head moves from side to side during
operation. This is perfectly normal and is indicative of the pump head
attachment method.
• After the pump has stopped, the pump may rotate for approximately two
seconds in the reverse direction. After each flush, it may appear that
bubbles in the tube are flowing back to the water container from the
OFP-2 pump head. This is a perfectly normal operation to help reduce
the pressure within the tube.
7.
To refill the water container while using it on a patient, press the standby switch to put the
OFP-2 on standby, keep the pump head lever closed so the tube is not disturbed.
Pull the tube from the water container cap and remove the container from the unit. Unscrew
the cap, fill the container with the appropriate fluid then secure the cap. Place the container
back on the unit. Push the tube into the container cap up to the indicator line. Press the
standby switch to put the OFP-2 back into “run mode”.
CAUTION
• During the water container refilling procedure, ensure that the tube is
handled appropriately to prevent contamination.
• Should the tube become contaminated during the water container filling
procedure, replace with a new tube.
