General
Information
Attention:
This manual contains important
information for the safe use
of this product. Read this
manual completely and do not
throw away. Reasonable care
and safe methods should be
practiced. Check local codes and
requirements before installation.
Warning: Before handling pumps
and controls, always disconnect
the power first. Do not smoke or
use sparkable electrical devices
or flames in a septic (gaseous) or
possible septic sump.
Unpacking Panel:
When unpacking the unit, check
for concealed damage. Claims
for damage must be made at
the receiving end through the
delivery carrier. Damage cannot
be processed from the factory.
CALIFORNIA PROPOSITION
65 WARNING:
This product and
related accessories contain
chemicals known to the
State of California to cause
cancer, birth defects or other
reproductive harm.
Panel
Installation
Electrical Connections:
Panel Opening – Wiring: The
enclosure opening for intrinsically
safe wires must not be used for
non-intrinsically safe wiring.
This is to be the only opening in
the intrinsically safe area of the
enclosure. If this is not done, the
UL Listing for the control panel
will be void.
Electrical Connections:
The contractor must conform
to the latest requirements of the
National Electrical Code. All
conduit and cables shall have
conduit per NEC Code NFPA
#70, where conduit and cable
leave the hazardous locations.
Prior to conducting any
installation, repair or service with
regard to the control panel, refer
to the schematic appropriate for
that panel. The schematic will
provide guidance with regard
to terminal block connections.
Electrical ratings are indicated on
the schematic for terminal blocks
used in interfacing with controls
remote from the control panel. If
these ratings are violated, the UL
Listing for the control panel will
be void.
Make the Following Electrical
Connections:
Connect the pump heat sensor
and seal failure leads to the
appropriate terminal blocks in
the non-intrinsically safe area
outside the barrier in the control
panel. Connect all the float
control leads to the appropriate
panel terminal blocks in the
intrinsically safe area within
the barrier in the control panel.
If guaranteed submergence of
the pumps is critical to this
installation, contractor must
be very careful in locating the
floats at the proper elevations.
The maximum distance between
the control panel and the floats
is the lesser of 300 feet or the
maximum distance recommended
for the pump.
Connect the pump leads to the
overload relay on the control
panel. When connecting the
pump leads it is very critical
that the proper sequence
be maintained.
On single-phase pumps, the
white, black and red pump
leads must be connected to the
pump terminal blocks in the
panel exactly as shown on panel
markings and on the schematic.
Note: Pump will run only if leads
are connected as shown.
On three-phase pumps, ensure
proper phase sequence while
connecting to the overload relay
in the control panel. Incorrect
phase sequence will result in the
reverse rotation of the pump.
Note: Make sure pump ground
wire is connected to the panel
pump ground lug.
Before connecting power to
the control panel, make sure all
control switches (ex. H-O-A
switch) and protective devices
(ex. breakers) are in the Off
position. Now connect power to
main power terminal blocks or
the circuit breaker as directed
by the schematic. Control panel
must be grounded properly per
NEC and/or local codes. To
facilitate this, a ground lug is
provided on the control panel.
Panel Check List
Check List:
Check junction box for moisture.
Moisture may cause chattering of
relays/contactors.
Check O/L relay settings and
verify reset mode.
With H-O-A switch(s) in Off
position, energize power to panel.
Check voltage to the panel and at
secondary of control transformer
using a voltmeter.
Check float operation and
response of control panel
to the float operation. For
sequence of operation refer to
design specification.
