length, control panel location and
conduit length must allow the
cords to run continuously to the
control panel without splices.
Step 4
Make the electrical connections at
the control panel. Seal the opening
of the conduit at the entrance into
the control panel with electrical
putty or a similar sealant to
prevent sewer gases from entering
the control panel.
Failure to properly seal the
electrical conduit from the basin
at the entrance to the control
panel may allow sewer gases
to condense inside the control
panel and cause premature
panel failure. Warranty claims
for this type of failure cannot be
processed by Hydromatic.
Electrical Connections:
Risk of electrical shock or
electrocution. May result
in serious injury or death or
fire hazard. Installer must
disconnect all electrical sources
prior to installation. Only
qualified personnel may install
this system. NFPA 70/National
Electric Code (NEC) or local
codes must be followed. System
must be properly grounded
according to NEC or local codes.
NOTE: Failure to use a
Hydromatic approved control
panel voids the pump warranty
and guarantee.
IMPORTANT: Properly
connect the panel ground wire
to a grounding rod. Improper
grounding voids warranty.
junction box to all incoming
control panel wires.
Step 4
It is recommended that the
customer furnish and install a
conduit seal outside the basin
to prevent surface water from
entering the junction box.
Systems Without Junction Box:
Step 1
An inlet grommet for 2" PVC
conduit is the standard supplied
electrical conduit connection
device. If another type of
connection device is used, refer
to the directions included with
the device. Determine the point
at which the electrical conduit
will enter the basin and, using a
3" diameter, properly maintained,
piloted hole saw, drill a hole
through the basin wall. If using a
fiberglass basin, clean the edges
of the hole and apply a sealant
coating to the cut section to
prevent fiberglass deterioration.
Insert the inlet grommet into the
drilled hole.
Failure to use a properly piloted
hole saw may result in damage
to the basin which may result
in structural failure of serious
leaks.
Step 2
Lubricate the inside lip of the inlet
grommet with pipe soap. Clean the
outer end of the conduit and push
the conduit through the grommet.
Ensure that the conduit does not
protrude inside the basin so as to
interfere with pump removal or
float operation.
Step 3
Fish the pump and float switch
cords through the conduit to the
control panel. The pump cord
Panel Wiring:
Step 1
Ensure power source is off or
disconnected.
Step 2
Connect pump power and float
cords to panel terminals per the
schematic provided. All conduits
and cables entering the panel must
be sealed off.
Check panel wiring to ensure
white, black, and red pump leads
are connected according to the
schematic and panel wire labels.
Single phase pumps will run only
if connected one way.
Cutting r
isk. Risk of serious
cutting or amputation exists.
Disconnect all power sources
prior to handling or servicing
pump or grinding mechanism.
Pump may start without
warning. Grinding mechanism
is extremely sharp. Use caution
when handling the grinder
mechanism. Do not leave pump
in basin unless it is placed in
operation. If a pump has been out
of service for an extended period
of time, with the power off, rotate
the impeller by turning the radial
cutter with a screwdriver to be
sure it rotates freely.
Preoperational Grinder Pump
Checks:
Step 1
Ensure power source is off or
disconnected.
Step 2
Remove pump from basin.
