Connection Tightness:
After thread sealant is applied, tighten all connections by hand (3.5-6 turns, depending on pipe
size), then use the following Turn Past Finger Tightness guide to complete the tightening
process:

NOTE: Never loosen a fitting for correct alignment. Doing so will prevent the thread from
maintaining a proper seal.
CAUTION: Do not overtighten the connection. Overtightening can damage threads, pipes,
fittings, and the eFlo device.
Leak Checking
Before operation, all plumbed components should be leak checked. To avoid damage to
sensors and other components, check with SSi for the maximum pressure for the sensor in
your eFlo device (the installed sensor may vary based on the parameters needed in your
particular application).
IMPORTANT!
Ensure that the inlet pressure is within specified parameters for your eFlo unit.
