Overview
The Hydro-Guard HG-6 Hydrant-
Based Flushing System is a
portable and emergency use device
designed to flush water lines from
fire hydrants located anywhere in
the distribution network. These
devices require the hydrant to be
live when programmed for flushing.
The HG-6 has been engineered and
manufactured to provide outstanding
dependability and performance.
1.
Remove the Hydro-Guard Unit
from its packaging and inspect
for possible damage during
shipping.
2.
Using the pumper nozzle, flush
hydrant for several minutes to
ensure the water flow is free of
debris (i.e., rocks, etc.)
3.
Confirm hydrant is turned off.
4.
Gather 2" NTP connector and
hydrant wrench.
5.
If necessary, loosen but do not
remove the four bolts on the
side of the Hydrant Flusher
in order to adjust connection
height, ensuring the device is
supporting its own weight. Once
proper height is determined,
tighten the four height
adjustment bolts.
6.
Connect the Hydro-Guard Unit
by means of the 2" threaded
nipple and supplied hose
adapter.
7.
Open the hydrant’s valve in
order to charge the hydrant.
flow away from the Hydro-Guard
Unit or to be absorbed by the
surrounding soil. The Unit’s ground-
level erosion controlling splash
plate is designed to disperse the
water energy from the discharging
water and reduce the risk of
erosion from around the base of
the fire hydrant. In order to prevent
undue pooling of the effluent water,
multiple nightly flushes are effective
in managing discharge volumes.
8.
If the HG-6 has been shipped
with the Dechlorination System;
remove the security screws at
side of unit to access, remove the
dechlorination chamber, open, fill
with sodium sulfite or ascorbic
acid tablets, reinsert and replace
security screw.
9.
Disinfect the Hydro-Guard
Automatic Flushing Device in
accordance with the utility’s policy.
Do not exceed the dosage and
contact times recommended
by the American Water Works
Association.
10.
The Hydro-Guard Automatic
Flushing Device may now be
programmed and placed
into service.
