1.3 Overview Filter Components
HN-G models are automatic, self-cleaning screen-type water filters. The filtration system consists of a filter body, hydraulic piston, filter
screen, Self-Clean mechanism and drain valve.

1.4 Operation
Pressurized water enters the filter inlet and travels through a filter screen
where contaminants are filtered out. The clean water then
exits through the outlet .
The build-up of contaminants on the filter screen creates a differential pressure across the filter. Based on a preset Differential Pressure (DP)
programmed into the Backwash Controller (HN-G-01-1-XXX, HN-G-02-1-XXX models only), the drain valve will open and the backwash of the
filter screen will take place. After 7 seconds, the drain valve is closed to resume normal water filtering. A backwash of the filter screen can
also be initiated by a programmable timer.
The minimum pressure required for Self-Clean is 40 PSI (2.8 Bar).
NOTICE
Large particles may prevent the self cleaning mechanism from working properly. In that case, we recommend installing a coarse
strainer (10-14 mesh) prior to the filter.
