12. Release the negative pressure ball. If the negative pressure ball is fully expanded
within 30s, it indicates that the float flowmeter leaks. Handle this problem as described
in the troubleshooting table.
13. Pull out No.27, 28 and 29 PU tubes (No.27 and 28 tubes in case of O2+N2O
configuration, No.27 and 29 tubes in case of O2+AIR configuration, and No.27 tube in
case of single O2 configuration) which connect the flow regulator to the throttling
device. The ends of the tubes which connect the throttling device are pulled out but the
other ends are not.
14. Occlude the pulled-out tube end on the throttling device by using 3126-08-00 tube
plug.
15. Flatten the negative pressure ball to remove the gas inside. Then re-install the gas
outlet switch of the negative pressure ball properly. Connect the other end of the
negative pressure ball to the pulled-out end of No.26 PU tube through 3106-06-00
adapter connector, as shown below.
16. Release the negative pressure ball. If the negative pressure ball is fully expanded
within 30s, it indicates that the throttling device leaks. Handle this problem as
described in the troubleshooting table.
17. Pull out No.46, 49 and 51 PU tube (No.46 and 49 tubes in case of O2+N2O
configuration, No.45 and 51 tubes in case of O2+AIR configuration, and No.45 tube in
case of single O2 configuration) which enter the flow regulator. The ends of the tubes
which connect the flow regulator are pulled out but the other ends are not.
18. Occlude the pulled-out tube end on the flow regulator by using 3126-06-00 or
3126-04-00 tube plug.
19. Flatten the negative pressure ball to remove the gas inside. Then re-install the gas
outlet switch of the negative pressure ball properly. Connect the other end of the
negative pressure ball to the pulled-out end of No.27,28 or 29 PU tube in turn (No.27
and 28 tubes in case of O2+N2O configuration, No.27 and 29 tubes in case of
O2+AIR configuration, and No.27 tube in case of single O2 configuration) through
3106-06-00 adapter connector, as shown below.
