subassemblies (p/n 18530-001) with
attached tubing only needs to be
disassembled when it is necessary to
replace individual tubes or components
within the subassemblies themselves
To replace internal flexible tubing:
The LTV
®
1200/1150 ventilator contains additional components/tubing and consequently a
more complex tube routing configuration than other LTV
®
model ventilators. Detailed
replacement instructions are necessary and are based on the assumption that some or all of
the tubing, the Accumulator, Solenoid Mount assembly, Manifold to Back Panel Spacer, and
Analog PCBA or Solenoid Manifold has been removed from the ventilator.
Beginning with subassembly construction and initial tube attachment requirements to the
Solenoid Manifold and Solenoid Mount assemblies, the instructions are grouped together
and sequenced as necessary to accommodate all required tubing point to point connections,
routing and layering configurations.
1) Inspect all flexible tubes for excessive wear, tears or cuts and replace if worn or
damaged.
• See Tubing Table in this chapter for detailed descriptions and part numbers
of individual flexible tubes.
2) Route and reattach or replace the removed tubes (per the following instructions) by
gently twisting and pushing the ends of the tubes onto the appropriate ports,
elbows or tees.
CAUTION
Final Tubing Check - Anytime internal flexible tubing is removed or replaced, check to
ensure all tubes have been correctly routed (point to point and layering), are fully connected
on the ports or fittings, and do not have any holes or tears in them. If necessary, gently
reposition the tubing to eliminate possible kinks or occlusions.
