The inserts create a restriction in the flow stream and may cause clogging Where this could be a problem we suggest using one of the other three installation systems instead Because the flow metering inserts are installed from street level it is not possible to measure the level Instead you must set the level to zero before installing the flow metering insert in the pipe Set the level to zero using the following instructions 1 Install the module in the Sampler and remove the red cap from the desiccant cartridge 2 Assemble the flow metering insert to the length that will be installed 8 Attach the bubble line to the module The inside of the bubble line must be dry and unobstructed 4 Turn on the sampler and wait 2 to minutes to allow the bubbler s air system to stabilize 5 Select Program from the sampler s main menu and step through the screens until the Current Level screen appears Detailed programming instructions appear in the sampler manual 6 Adjust the level to read zero 0 00 feet or meters 3 1 730 Bubbler Module Section Installation Methods You may exit the programming after setting the current level to zero When you install the flow metering insert the bubbler module will then provide liquid level readings based on this zero level 7 Proceed with installing the insert into the pipe 3 1 2 Spring Rings Consult your Isco Mounting Rings instruction manual for detailed hardware informati
