Component Removal/Installation
5. Reconnect the green ground wire to the inspiratory manifold.
6. Install four screws and washers at the inspiratory outlet port (Figure 9-
72), but do not tighten until the outlet port is installed and secured.
7. Inspect the inspiratory outlet:
•
Check the o-ring on the inspiratory outlet, and replace if cracked
or deformed. Lightly lubricate the o-ring with Krytox GPL226
lubricant.
•
Check that check valve CV3 in the inspiratory outlet is oriented
and seated properly.
8. Insert the inspiratory port completely into the inspiratory manifold and
fasten by tightening the locking screw (Figure 9-71). Pull on the
inspiratory outlet to ensure it does not come out or rotate.
9. Reconnect the SV, inspiratory, and exhalation tubes to the solenoids
10. Reconnect all remaining tubes to the inspiratory manifold (Figure 9-
70).
11. Reconnect the cables labeled EXHAL SOL, INSP SOL and SAFETY
SOL (Figure 9-70).
12. Install the enclosure brace and top enclosure (see “Top Enclosure” on
Installing the Cable
Extension Kit
Updated three-station solenoids and crossover solenoids (SOL1) are used to
manufacture Esprit ventilators. Because the electrical connectors on these
solenoids differ from the original versions, a cable extension kit (P/N
1010867) must be installed when replacing the original versions of any of
these components:
•
Three-station solenoid
•
Inspiratory module (which includes a three-station solenoid)
•
Crossover solenoid
•
Oxygen valve assembly (which includes a crossover solenoid)
Install the cable extension kit to the main PCB to motor cable (P/N 610-1000-
05) to make the electrical connector(s) compatible with the updated
component(s):
1. Use wire cutters to remove electrical connector(s) from the main PCB
to motor cable (Figure 9-73). Cut as close to connector as possible,
and remove only the connector(s) for the component(s) being
