Bleed Ports
Liquid Devices
Liquid devices include bleed ports (8-32 Nylon-tipped screw)
on the front for the removal of air bubbles.
✓
Note:
A small amount of liquid will leak from the
device during this procedure. Take necessary
precautions to prevent damage to anything nearby.
Bleed both of the ports as follows:
1.
With the device installed, start a flow greater than 50% of
full flow. Gently loosen the upstream bleed port screw 1
to 2 turns, or until liquid begins to leak from the threads.
Do not remove the screw
, as it has pressure behind it, is
very small, easy to lose, and delicate to rethread.
2.
Gently tap the flow body to remove air bubbles (screwdriver
handles work well). This may not be visible or audible.
3.
Gently tighten the screw until the leakage stops, taking
care not to crush the nylon tip.
4.
Repeat steps 1–3 with the downstream port.
✓
Note:
If your device is mounted in an inverted
position, avoid using the bleed screws, as liquid
may leak and cause permanent damage.
