OVERVIEWThe Aqua-Lab Bug Prep Kit 2.0 integrates injector-based chemical dispensing with a pressure switch actuated foaming prep gun and a high temperature shutdown system to protect your pumps. The injector plugs into a Hydra-Cannon position and turns on the pump to create boosted chemical solution when a hand actuated gun is squeezed. If a failure occurs somewhere in the system causing the pump to run and bypass water, the temperature switch detects the temperature increase and shuts down the pump. If the pump is shut down due to a temperature trip, a red light will become illuminated.

BUG PREP KIT 2.0 RETRO INSTALLATION STEPS

1. Mount bug prep pressure switch box within 3’ of Aqua-Lab panel M12 junction block.

2. Mount temperature overload box next to panel within 32” of the bug prep pressure switch box and within 14’ of the pump that plumbs into the corresponding Aqua-Lab panel the bug prep.

3. Shutoff water to pump inlet, turn off power to pump (not shown).4. Close ball valve at the Hydra-Cannon inlet.

5. Disconnect quick connect on feed line to panel (not shown).6. Aim hose at drain. Open ball valve and run till water stops coming out of hose.

7. Plumb temperature switch into bypass line (see photos below).

8. Connect injector to manifold. Route 1/2” poly flow to top port on pressure switch box.

Cut Bypass line close to the end of hose bar, loosen hose clamp

Plumb in temp switch to regulator, connect hose to hose barb and re-tighten hose clamp

9. Plumb outlet solution line (3/8” poly flow from side port of pressure switch box) and airline to bay (not included).

10. Connect solution and airline to dual lumen hose.

11. Connect dual lumen hose to wye connector on foaming gun (Red Line or Black Line (depending on the age of your system) is used for air, Blue Line is used for chemical solution).

12. Attach M12 connector on injector manifold to corresponding Aqua-Lab junction block port.

13. Connect Din I to corresponding Aqua-Lab electric actuated air valve.

14. Connect 3 pin electrical quick connect on injector manifold to 3 pin electrical quick connect on temperature shutdown box.

15. Connect 2 pin electrical quick connect on temperature switch to 2 pin electrical quick connect on temperature shutdown box. a. Turn on water supply to pump (not shown). b. When water is coming out of feed line for 30 seconds close ball valve, re-prime pump (not shown). c. Reconnect feed line to panel (not shown). d. Press red light on temperature overload box.

16. Open ball valve on feed line, pump and valve will activate until 100 psi is stored in line. Once pressure is made between the gun and valve, the pump will turn off after approximately 20 seconds (not shown).

17. Verify that the system is leak free (not shown).18. Verify that the pump turns on when the gun trigger is squeezed (not shown).19. Verify the pump turns off when the gun in closed (not squeezed). Pump should turn off after

approximately 20 seconds of releasing the gun (not shown).

BUG PREP KIT 2.0 INSTALLATION STEPS

1. Mount bug prep pressure switch box within 3’ of Aqua-Lab panel M12 junction block.

2. Close ball valve at the Hydra-Cannon inlet, turn off power to pump.

3. Connect injector to manifold, route ½” poly flow tubing to top port on pressure switch box.

4. Plumb outlet solution line (3/8” poly flow from side port of pressure switch box) and airline to bay (not included).

5. Connect solution line and airline to dual lumen hose.

6. Connect dual lumen hose to wye connector on foaming gun (black line is used for air, blue line is used for chemical solution).

7. Attach M12 connector on injector manifold to corresponding Aqua-Lab junction block port.

8. Connect Din I to corresponding Aqua-Lab electric actuated air valve.

9. Once all plumbing and electrical connections are made, turn on power to the pump and slowly open the ball valve at the inlet of the Hydra-Cannon manifold. The pump will remain on until 100 PSI is stored in the solution outlet line. (This should take approximately 20 seconds.)

10. Verify that the system is leak free.

11. Verify that the pump turns on when the gun trigger is squeezed.

12. Verify the pump turns off when the gun in closed (not squeezed). Pump should turn off after approximately 20 seconds of releasing the gun.

STANDARD OPERATING PROCEDURE1. Squeeze hand applicator trigger.

a. Pump will turn on and valve will open simultaneously.

2. Apply solution to vehicle.

3. Release hand applicator trigger. a. Pump will build pressure in the bug prep solution line to 100 PSI and pump will shut down approx. 20 seconds later.

1. Close ball valve at inlet to Hydra-Cannon manifold.

2. Press red button on electric actuated air valve to purge pressure. a. Press and hold red button to purge pressure. Disconnect ball valve from Hydra-Cannon Inlet once pressure gauge reads 0 PSI.

3. Point valve towards drain, and slowly open to flush water through pump. Flushing water through pump will cool down the thermal switch. Once the thermal switch is cooled, press the illuminated red light on temperature overload box and reconnect ball valve to the panel.

4. Open ball valve.

HOW TO REDUCE TEMPERATURE IF TEMPERATURE OVERLOAD BOX

IS TRIPPED

PREVENTATIVE MAINTENANCE

TROUBLE SHOOTINGPROBLEM POTENTIAL CAUSES SOLUTIONS

Injector Does Not Draw Chemical

1. Back pressure is too high.2. Metering tip clogged.3. Foot valve is clogged.

1. Reduce foaming air pressure.2. Increase nozzle size.3. Increase solution outlet line size.4. Clean/replace foam generators.5. Clean metering tip.6. Clean foot valve.

Pump Does Not Turn On

1. Temperature overload is not plugged in.2. Light on temperature overload box is illuminated.3. Temperature overload is tripped.4. Ensure line pressure is < 50 PSI

1. Plug temperature overload box in.2. Press temperature overload reset button.3. Reduce pump temperature by purging pump system with cold water, hit reset button once pump has been purged with cold water.4. Verify with injector optimization tool (P/N: 1002018)

Pump Will Not Turn Off1. Leak in line2. Pressure switch failed3. Ensure line pressure is > 50 PSI

1. Fix leaks2. Replace injector manifold3. Replace check valve on airline4. Verify with injector optimization tool (P/N: 1002018)

Air Valve Chatters 1. Back pressure is too high 1. Decrease back pressure to below 60 PSI

No Foam 1. Chemical lacks surfactants needed to foam

1. Switch chemical

TIME FRAME ACTION

Daily Check for standard operating function: When the gun handle is squeezed, the pump turns on. When the gun handle is released, the pump turns off.

Weekly Check for leaks that may cause the pressure switch to trigger.

Monthly Inspect check valves on airlines to make sure valves are working. Replace when needed.
