and the length rising out of the
ground at the control panel.
NOTE: Wiring must be installed
per national and local codes.
Conduit must enter panel from
bottom and be sealed per NEC
section 300.5 & 300.7.
8a. Installing E/One supply
cable:
1)
Open the lid of the station,
Locate the cable and the feed-
thru connector on the wall of
the shroud. If the station has
a field joint and was delivered
in two pieces, be sure both
halves of the EQD are securely
assembled together. Loosen
the nut on the connector
and pull the supply cable out
through the connector until it
hits the crimped on stop feature
on the cable, approximately 24”
from the EQD.
**IMPORTANT:
All but 24” of the cable must be
pulled out of the station, and
the EQD and Equalizer should
be hung as high in the station
as possible to ensure that the
pump functions properly. Do
not leave the excess cable in
the station.
2)
Retighten the nut. This
connection must be tight or
ground water will enter the
station.
3)
Feed the wire through the
length of conduit (contractor
provided), which will protect it
until it is below the 24” burial
depth.
4)
Position the conduit
vertically below the cable
connector along side of
the station reaching down
into the burial depth. Attach
the small fiberglass guard
(protective shroud) provided
with the station to protect the
exposed cable where it enters
the station. Four self-tapping
screws are provided.
5) Run the cable
underground, in a trench or
tunnel, to the location of the
panel. Leave a 6- to 12-inch
loop of cable at each end to
allow for shifting and settling.
Connections made at the panel
are shown in Figures 2a and
2b.
9. DEBRIS REMOVAL:
Prior
to start-up test procedure, the
core must be removed and the
incoming sewer line flushed to
force all miscellaneous debris
into the tank. Next, all liquid
and debris must be removed.
Once tank is clean, re-install
the pump and proceed with the
test.
10. TEST PROCEDURE:
When the system is complete
and ready for use, the following
steps should be taken to verify
proper pump and high level
alarm operation:
a) Make sure that the
discharge shutoff valve is fully
open. This valve must not
be closed when the pump is
operating. In some installations
there may be a valve, or
valves, at the street main that
must also be open.
(Ignore all Trouble
indications, LEDs and/or
messages until the panel
is reset at the end of this
procedure.)
For models DH272 and
DH502:
b) Turn on the alarm breaker.
c) Fill tank with water until the
high level alarm turns on. Shut
off water.
