Operation
Initial Start-Up
1. Open all air vents so that air is eliminated from within the coil circuitry and headers.
Verify that all vents and drains are not obstructed and do discharge a stream of water.
2. Fill the coil with water then close all vents.
3. Perform an initial hydrostatic leak test of all brazed, threaded or flanged joints, valves
and interconnecting piping. Recheck the coil level and correct if necessary. When the
setup is found to be leak free, discharge and discard initial water charge. It is important
that all grease, oil, flux and sealing compounds present from the installation be removed.
