slowly turn on the main water supply. Let the water run for a few minutes or until the
system is free of any air or foreign material.
2. Make sure there are no leaks in the plumbing system before proceeding and shut off the
nearest faucet when water runs clear.

WARNING! If the system is leaking at all, turn the unit to the bypass position and shut off main

STEP 5. Flushing and Testing the Plumbing Lines
IMPORTANT! Flushing the system lines is necessary to ensure that all plumbing work has been
done correctly, that there is no debris or air trapped in the piping, and that there are no leaks.
IMPORTANT! The system is not ready for service until you complete the “System Initialization”
section of the owner’s manual.
