Plumbing
The feeder can be mounted on a horizontal or vertical cold water supply line.
It must be installed with a manual by-pass valve and unions (as shown
above) for future serviceability. Arrows on the valve indicate direction of
water flow. Do not install feeder on hot water supply.
IMPORTANT: It is important to prevent any contaminants from entering the
feed valve during or any time after installation. The feeder must be installed
with non-ferrous plumbing materials only to prevent rust from contaminating
the valve. Apply pipe compound sparingly. Remove and clean the feed valve
strainer after the first feed cycle to remove any contaminants that could have
been introduced during installation. See Service / Maintenance on page 4 for
additional information.

What should the display flash? Mine is 292.
The display on a Hydrolevel Company VXT-120 flashes when the digital counter has “rolled over” (exceeded 999). If the display shows 292, it is not flashing due to rollover. Flashing only occurs when the feed amount exceeds 999, indicating an excessive feed amount.
