MODEL:Hi Flow, Stroller, and Sprint

ISSUE:Hi Flow, Stroller, and Sprint SRV Retrofit Kit Instructions

NOTES:

This instruction is to guide technicians how to remove the SRV mounting from the FCV onmeter Sprints and Strollers. This was a plumbing consolidation for the Sprint and Stroller
Models that have capacitance meters. This will also streamline the 30PSI Secondary Relief
Valves. These kits are required for the Sprint, Stroller, or Hi Flow Strollers with meters inthe event that there is a need to replace the Flow Control Valve as these will no longer have
the SRV port in them.
WARNING: Do not use the new FCV that does not have the SRV port without installingthe entire kit.

1. Procedure A: Sprint Retrofit PN 21373979 & 21373980
Caution: The unit must be empty, warm and vented before starting procedure.
1.1 Remove the condensation pad cover from the bottom of the unit.
1.2 Remove (2) screws from bottom assembly as shown.

Ref 21368597 Rev B

Figure 1.2
1.3 Remove the strap from the unit if attached. Remove the knob and decal
from the Flow Control Valve (FCV). Remove the dome cover then remove thethree screws as shown.

Figure 1.3
1.4 After screws are removed, pull the top cover off the unit and pull out theassembled bottle.
1.5 Use a Phillips head screw driver #1 to remove screws from the top of the FCV
locking plate to release the FCV from bracket. Use a 3/8” Wrench to remove
the fitting from the bottom of the FCV.
Note: Save the Secondary Relief Valve (SRV) from the old FCV for step 1.7

Figure 1.5
1.6 Slide the new FCV back through the bracket and reattach the fitting to thenew FCV with the 3/8” wrench. Attach the locking plate back on top of FCV
with the 2 screws using a Phillips head screw driver #1.

1.7 Remove the Secondary Relief Valve (SRV) from the FCV with a 9/16 Wrench(make sure threads are clean) and attach to the Street Tee fitting (PN21385560), torque SRV to 80-90 in/lb when reinstalling. Remove the PRVfrom the plumbing with a ½ Wrench, clean off threads, apply new Teflon
tape leaving the 1st thread bare, and attach to the Street Tee fitting.

1.8 Attach Street Tee fitting PN 21385560 to plumbing where the PRV wasremoved. See Figure 1.8 A for Side Fill and Figure 1.8 B for Top Fill.

1.9 After assembly is complete with the new FCV and Street Tee fitting, thebottle can be put back into casing and assembled back together.
2. Procedure B: Hi FLOW and Stroller Retrofit PN 21371863, 21371865, and21371866.
Caution: The unit must be empty, warm and vented before starting procedure.
2.1 Follow steps from Procedure A 1.1 through 1.5.
Note: For HI FLOW, remove from casing and continue to step 1.5 from
Procedure A.
Note: Save the SRV from the old FCV for step 2.2
2.2 Assemble the SRV onto the Manifold Tee (PN 21237266), which will comewith Fitting Feedthru (PN CA404841) and Ferrule (PN B-775068-00) alreadyattached, tighten to 80-90 in.-LB. The wire harness assembly will be threaded
through the Manifold Tee by the red wire. Manifold tee assembly will beneeded in step 2.6.
Note: Feed the red wire through. Do not pull on the wire or it could strip
the insulation of the wire.

2.3 Disconnect the meter wire harness and remove the (2) mounting screws
from the meter.
2.4 Remove the (3) screws on the bracket and lift the bracket from the manifold.
2.4.1 For Top fill, remove fitting 1 with a ½ Wrench and fitting 2 with a
9/16 Wrench from the plumbing as seen in figure below.
2.4.2 For Side fill, remove fitting 1.

2.5 Remove (4) screws from the top of the mainfold with a hex key wrench.
2.6 Remove the manifold assembly from the Dewar.
2.7 Remove the ¼ ‘’ wide heat shrink insulation collar and unsolder the wirefrom the probe.
2.8 Solder the Pull Wire CA406704 to the end of the Probe Wire. This wire will
be used as a tool to pull the wire harness through the heat shield.

Figure 2.8
2.9 Remove the fitting on the mainfold with the red and blue wire harness using
a 3/8 Wrench. As the fitting is removed from the manifold, the pull wire will
also be pulled through the heat shield and manifold.

2.10 Unsolder the Pull Wire from the removed probe wire and re-solder it to
the manifold tee assembly.
2.11 The manifold tee assembly will be threaded through the hole that thewire harness was removed from. Tighten it finger tight and then 1 flat more.
NOTE: Only spin the brass nut on the manifold tee when tightening, not thewhole body.
2.12 After using the Pull Wire to pull the harness asemby through the heatshield, it can be unsoldered. The harness will now be slid through the new
1/4" wide heat shrink insulation collar, and soldered back to the probe. Heat
shrink the insualtion collar (PN11370584) to support the wire. Add fittingback under the manifold tee. Tighten it finger tight plus 1 flat. See below forcompleted manifold.
Note: Be sure to not have any solder material touch the inner probe. This
will affect the capacitance.

Figure 2.12.2
2.13 Insert manifold back into the bottle and secure with (4) screws using theT-handle. Reattach fittings from step 2.4. Reattach the bracket (see Figure
2.13.1) and meter (see Figure 2.13.2).

Figure 2.13.1
Figure 2.13.2
2.14 Insert the new FCV into the bracket; attach locking plate on the top of
FCV and fitting to bottom of FCV. Tighten it finger tight plus 1 flat.
