4) Verify the thermo conductive pad is applied to the inside of the back panel. If it is not,
apply one. See instructions on page 8-130 to install.
5) If necessary, remove the spiral wrap from the flow valve's Stepping Motor 4-wire lead
wires.
6) Verify that the length of the clear flow valve tube is 5.00" ± 0.250" and that it is properly
routed. Refer to the routing instructions, tables and diagrams beginning on page 8-33.
7) Verify that the Tee Fitting has been installed to the middle port tubing of the Pilot-out
Solenoid (solenoid closest to the ventilator pressure ports on the Solenoid Mount) and
that the tube is properly routed. Refer to the routing instructions, tables and diagrams
beginning on page 8-33.
8) Verify that the Motor PCBA C52 capacitor (large capacitor located on the top of the
Motor PCBA) is secured with a tie wrap to the PCBA.
9) Visually inspect all flexible tubes to verify there are no tears, rips, pinholes or loose
connections.
10) Verify that the loop of tubing connecting the Flow Differential transducer to the solenoid
manifold does not loop past the edge of the power PCBA.
11) Verify that no tubing is kinked or twisted, and that it will not be pinched when
compressed by the back panel. Refer to the routing instructions, tables and diagrams
beginning on page 8-33 to check the tubing routing. Always check ALL tube routing
for kinks or compression that might result in restricted flows prior to closing the
ventilator.
12) Inspect the grounding clips on the back panel and replace if they are missing or not
making good connections. Missing or damaged grounding clips should be replaced
using Loctite 4541 Adhesive.
13) Verify the grounding clips connected to the oxygen blender are aligned correctly inside
the housing (clips should not be visible when screws are tightened down). (LTV
only) See O2 Blender Assembly in Chapter 8.
14) Verify the power cable for the oxygen blender is properly routed under the motor board,
behind the connection bus to the power board (LTV
15) Verify that the power cables for the turbine, sounder, fan Assembly, oxygen blender
