or exceeds 15 psi while the RO is running
1.
Start with all valves, sample ports, vents, and drain ports closed.
2.
Open the drain port on the bottom of the housing to allow the water to drain completely from
the housing. Close the drain port when water flow stops.
3.
Depending on the filter housing either open it, or use a filter wrench to gain access to the filter.
4.
Remove the old filter(s), and wipe out the inside of the housing with a clean, damp cloth.

. Insert the new filter(s).

Verify any o-rings are properly seated.

over-tightening.
8.
Slowly open the inlet valve to allow water to begin filling the housing.
9.
Partially open the sample port or vent to allow air to be purged from the device.

When water flows from the sample port or vent, signaling that the air has been purged from
the device, close the sample port or vent.

leaks.
