Equipment
Lumo 2” wetware
Strap wrench/wrench large enough to fit around the union collars
Hose nuts - minimum of 2
Adjustable crescent wrench
Plumbers grease
Lumo wrench or needle nose pliers
Phillips screwdriver
Remove the Current Wetware
Ensure there are no irrigations scheduled or currently running
Shut/close the ball/gate valve located before the Lumo valve
Manually open the Lumo valve to clear any residual water left in the valve
Turn off the manual irrigation once you see water stop coming out of the discharge port/hose
Disconnect the hoses from the dome and remove the nuts from the hoses attached to the wetware
Take the dome off of the wetware and set aside
Using your strap wrench, loosen the unions before and after the wetware
Use the wrench to start the process, then loosen the unions by hand
When loosening the unions on either side of the LUMO valve, there should be no difficulty doing this whatsoever. If you feel that this is extremely difficult and you need to consistently use the wrench to loosen the unions, stop immediately. This could mean a few things:
There is still water in the line and the system is pressurized
The union collars are cross-threaded and need to be re-aligned or very slowly and carefully loosened
Once the unions are loosened, slide the wetware out from between the two loosened unions on the manifold and set aside.
Installing the New Wetware
Take the new wetware and remove the unions
Find the arrow located on the wetware and make sure that it is pointed in the same direction as the flow of water through the manifold
Check the flow meter of the new wetware to ensure it spins with ease and is correctly seated and positioned
Place the new wetware between the unions on the manifold, making sure that the arrow is pointing in the direction of the flow of water
Ensure the o-rings are laying flat in their designated grooves on both the inlet and outlet side of the wetware; use plumbers grease on the O-rings if needed
Carefully align the ends of the wetware with the unions on the manifold
Hand tighten the union collars onto the newly installed wetware, then tighten ¼ of a turn with the wrench
Attach the hoses to the dome that was previously set aside
The short hose goes to the inlet that is closest to the bottom of the dome
The long hose goes to the inlet that is closest to the top of the dome
Make sure the nuts are hand-tight, then tighten with a wrench ¼ turn
Attach the dome to the wetware
Adjust/rotate the hoses so there are no kinks
Testing the New Wetware
Open the ball/gate valve slowly and listen for water to fill the Lumo valve, checking for leaks at the unions and hose connectors
Test the wetware by running a manual irrigation
Check Ops Center to ensure flow data is being tracked
If you do not see flow being registered;
Check that ball/gate valve is open
Check that the dome is properly seated on the wetware
Check that the hoses are properly attached to the dome and are not kinked
Check the irrigation LED indicator light
Check that the flow arrow is pointing the same direction of water flow
Check the pump to ensure it is powered on and functional
