(2) Set VENT MULTIMEDIA FILTER valve to OPEN.
NOTE
There should be air venting out of the pipe as the multimedia filter fills, followed by a steady stream of
water when the filter is full. If not, the vent line is probably blocked by a small piece of filter media. Notify
unit maintenance.
(3) Set VENT MULTIMEDIA FILTER valve to CLOSE as soon as a full stream of water flows out of vent pipe
(located at bottom right-hand front of trailer, below R.O. pump belt guard).
