PROCESS for RESOLVING INCONSISTENT INJECTIONS or PURGING CONTAMINATION from the Conditioning System

Note: Before starting on the following 12 or 23 step procedures, please read these “Suggestive Steps to Solve Inconsistent Injections”.  Try these first, and if issues persist, go to “Purging Contamination from the Conditioning System” below.

Suggestive Steps to Solve Inconsistent Injections:

Purging Contamination from the Conditioning System:

 Refer to pages 132-144 of the Envoy Operation & Service Manual (14-900101-000)

IF CLEANER IS ACCIDENTALLY ADDED TO THE CONDITIONER TANK BUT NOT CIRCULATED THROUGH THE SYSTEM:

DO NOT OPERATE THE MACHINE BEFORE CONDUCTING THE 14 STEP PROCEDURE below to contain the resulting white sludge from being spread through the rest of the conditioner system.  Conducting this procedure as soon as possible after the cleaner has been added to the conditioner tank will minimize the negative effects and avoid the need to conduct the 24-step process to purge the contamination from the complete conditioner system.

1. Remove the pump outlet tubing at the compression fitting where it connects to the inlet of the Spin-On Oil Filter.

2. Use union fitting to attach ~40” tubing (from spare parts kit or local hardware or plumbing store).

3. Place loose end of this tube into a 2-5 liter container to collect the waste fluid.

4. Go to the Diagnostics menu to activate the conditioner pump to pump all the fluid out of the conditioner tank.

5. Remove conditioner tank to remove any solid or gel that remains in the bottom of the tank. Use IPA99 if necessary to help remove any contamination from inside the conditioner tank before reinstalling.

6. Fill the conditioner tank with 99% Isopropyl Alcohol (61-860254-000/61-860254255-000 IPA 99) and purge any remaining conditioner/cleaner from the system tubing by activating the conditioner pump until the drain tubing in the waste container runs with CLEAR IPA 99.

7. Clean or replace the conditioner screen filter. (page 137-138)

8. Drain the Conditioning Supply Tank completely of all IPA 99. (pages 133-134)

9. Fill the conditioner tank with the desired new Conditioner.

10. Purge any remaining IPA 99 from the system tubing by activating the conditioner pump until the drain tubing in the waste container runs with CLEAR new Conditioner.

11. Remove the drain tube and reconnect the tube onto the compression fitting where it connects to the inlet of the Spin-On Oil Filter.

12. Replace the 11-655029-001 Spin-On Filter if necessary (pages 135-136). NEVER BYPASS the Spin-On Oil Filter when pumping fluid through the injector rail.

13. With the machine in the operating position, turn on the heat cycle to circulate the new Conditioner in the system for a few minutes to purge air out of the system.

14. Run the new Conditioner through the injectors by running a minimum of 5 lanes with the 100 Unit pattern for all 39 injectors for a single zone of 50 feet.

• If the above procedure was not effective or if you are unsure if you contained the cleaner in the conditioning tank before it was spread to the rest of the system, you will need to conduct the 23-step procedure below:

IF CLEANER WAS CIRCULATED THROUGH THE SYSTEM or if the injectors are suspected of contamination USE THE BELOW PROCEDURE.

Please purchase 2 each 11-655029-001 Spin-On Filters for Replacement During this Procedure.

Parts needed: 

• 2 Each 11-655029-001 Spin-On Filters
• 6 Quarts IPA 99% alcohol (61-860254-000/61-860254255-000)
• Teflon thread tape
  

1. Completely Drain the old conditioner and residue from the Conditioning Supply Tank (pages 133-134). Pump out as much of the existing conditioner from the tank and system tubing as possible (+Physically remove conditioner tank to empty liquid or contamination below the inner tubing level.) BEFORE adding any IPA99.  If the 11-655029-001 Spin-On Oil Filter is completely plugged and blocking the outlet of the pump, it may be necessary to replace it with a new filter at this time instead of at step #7 (pages 135-136). NEVER BYPASS the Spin-On Oil Filter when pumping fluid through the injector rail. 

2. Remove the accumulator from the accumulator rail and drain contents. Pour IPA 99 into the opening and fill to top. Shake the IPA 99 inside the accumulator to wash out any contaminates. Note: When replacing the accumulator, be sure to add Teflon tape to the threads of the fitting before reinstalling the accumulator.

3. Fill the conditioner tank with 99% Isopropyl Alcohol (61-860254-000/61-860255-000 IPA 99).
   

4. Purge any remaining conditioner from the system tubing by activating the conditioner pump until the drain tubing in the waste container runs with CLEAR IPA 99. 

5. Remove the drain tube and reconnect the tube from the accumulator rail to the pressure control valve.

6. Activate the conditioner pump to let the conditioner pressure increase to 45psi in the Diagnostics with the Oil Pressure Valve closed and then quickly turn the conditioner pump off.  Then open the Oil Pressure Valve to let the pressure drop to 0psi.  (This step helps purge residual conditioner that may be trapped in the accumulator).

7. Replace Spin-On filter with new one.
   

8. With the machine in the operating position, circulate the IPA 99 in the system for a few minutes to purge air out of the system (page 137).

9. Remove the buffer brush (pages 143-144

10. Create a special pattern that is 100 units of oil for all 39 injectors for a single zone of 50 feet.

11. Run the IPA99 through the injectors by running a minimum of 10 lanes with this pattern.

12. Drain the Conditioning Supply Tank (pages 133-134) by pumping out as much of the existing IPA99 from the tank and system tubing as possible.

13. Fill the conditioner tank with the desired new conditioner.

14. Purge any remaining IPA 99 from the system tubing by activating the conditioner pump until the drain tubing in the waste container runs with CLEAR new conditioner.

15. Remove the drain tube and reconnect the tube from the accumulator rail to the pressure control valve.

16. Activate the conditioner pump to let the conditioner pressure increase to 45psi in the Diagnostics with the Oil Pressure Valve closed and then quickly turn the conditioner pump off.  Then open the Oil Pressure Valve to let the pressure drop to 0psi. (This step helps purge residual IPA 99 that may be trapped in the accumulator).

17. Replace the Spin-on Filter: Remove the spin-on filter that has residual conditioner and replace it with a new spin-on filter.

18. With the machine in the operating position, turn on the heat cycle to circulate the new conditioner in the system for a few minutes to purge air out of the system.

19. Run the new Conditioner through the injectors by running a minimum of 5 lanes with the 100 Unit pattern for all 39 injectors for a single zone of 50 feet.

20. Run the Oil Injector Zig-Zag Test (pages 91-92) to assure that all injectors are properly firing with the expected pentagon shaped pattern.

21. Reinstall the buffer brush. (pages 143-144)

22. Select an actual pattern and run 10 lanes.

23. Use the Computer Lane Monitor to assure that the oil volume is correct for the selected pattern.
