Dechlorination
The Hydro-Guard
®
HG-8
Warm Climate Unit is equipped
with a dechlorination system.
Dechlorination takes place as a
portion of the discharged water
passes through a housing containing
either sodium sulfite or ascorbic
acid tablets. This action creates a
concentrated dechlorination solution
that then mixes with the non-directly
treated portion of the discharge to
effectively dechlorinate the entire
discharge volume.

options.
Integrated Sample Station
The HG-8 Warm Climate Sub-
Surface Discharge Unit, features
a Sample Port quick connect that
allows the end user to collect a
sample from the HG-8 installation
site. To collect a sample from the
sample quick connect the HG-
S116 Portable Sample Valve will be
required. (Recommendation: one
HG-S116 per every five HG-8 units)
You may wish to run a brief manual-
mode flush prior to the collection in
order to ensure water indicative of
the main-line water quality is being
sampled. Generally a two-minute
flush is sufficient. Track your residual
levels and alter flushing frequency
and/or duration in order to maximize
water conservation.

water quality at a specific flush point
and automatically initiate a flush
event when water quality conditions
warrant.
