Features
Finish Cover (1) - A nish cover is provided with each basin to help protect the basin top from
construction debris during installation. After basin installation, the cover can be removed for
cleaning then reinstalled for a clean and nished look.
Finish Flange Bolts (2) – Two ange bolts are provided to secure the nish cover.
Float Controls Cover (3) - The controls cover allows access to level control oat switch and
optional alarm.
External Control Module (ECM™) (4) - The optional ECM™ is an advanced control switch for a
sewage basin.
Pump Access Cover (5) - The pump access cover allows access to pump for removal and
installation. Removal of the access cover also allows the installer to monitor operation of the level
control oat switch and the optional alarm oat switch during installation or service.
Discharge and Vent Pipe Slip-Fit Connections (6 & 7) - The basin assembly is supplied
pre-plumbed with schedule 80 PVC discharge and vent pipe ready for immediate connection
to plumbing.
External Intake Hub (8) - Designed for a standard 4" slip-t connection allowing for
easy installation.

Start Up Procedure
Step 1
Remove nish cover and set aside.
Step 2
Remove bolts and washers from pump access cover and set cover aside.
Step 3
Observe position of pump. The pump should be upright with standoff feet located within the three
(3) integral torque stops (Figure 1).
Step 4
Verify that the pump discharge pipe is securely connected to the exit pipe (inside the basin) with
the exible coupling. If the pump is not in the correct position or the discharge pipe is detached,
reposition pump with pump legs located within the three torque stop features (raised molded
features on the bottom of the basin) and reconnect discharge pipe to exit pipe with exible
coupling and band clamps.
Step 5
Examine level control oat switch and optional alarm oat (if included). Verify the oat pole is
secured to bottom of control cover and there are no obstructions that might interfere with the
operation of the level control oat switch or alarm oat switch.
Note: The oat pole assembly (Figure 2) is assembled at the factory to specications for optimal
operation. The cord grips are installed for the primary and alarm oat (if equipped) tethered at
specied length(s). Changing the length(s) could result in system failure. Reference the oat switch
and/or alarm switch instruction manual for additional installation and operation information.

Step 6
External Level Control Option - If the basin is equipped with an External Control Module (ECM™),
verify that the sensor tube extending from bottom of control module (Figure 3) is not damaged.
Note: The cord/plug for the ECM™ (Figure 3) must be unobstructed at the plug end, to allow for air
to pass through the vent tube.
Step 7
Remove temporary pipe caps from the vent and discharge pipes.
Once the above steps are completed, plumbing connections
and electrical connections can be made.
Step 8
Connect the basin discharge pipe to drain pipe.
A check valve, not included, must be installed near basin to prevent backow into basin. For best
performance of check valves when handling solids, install in a horizontal position or at an angle not
more than 45 degrees.
Step 9
Connect the Pit+Plus® vent pipe to vent pipe.
Step 10
Connect piggyback plug to a 115 V outlet. Plug the pump power cord into back of piggyback plug
(Figure 4).
Step 11
Verify Operation - Once all plumbing and electrical connections have been made, ll basin with
water to activate controls and pump. If the unit does not operate, refer to the troubleshooting
guide located in the pump owner’s manual.

Pit+Plus Troubleshooting Guide
Condition Possible Cause Corrective Action
Pump will not
operate
Circuit breaker tripped or power
turned off Reset circuit breaker or correct electrical supply
Switch failure
1. Disconnect electrical power
2. Remove piggyback plug from outlet
3. Plug pump power cable into outlet
4. Turn on electrical power
5. If pump operates the switch is in failure mode
Pump will
operate, but
water/waste will
not exit basin
Blocked discharge pipe Remove blockage
Blocked vent pipe
Remove blockage
Note: Air admittance valves can create problems with sealed sewage basins. They
restrict the free passage of air in the vent pipe that is needed for efcient pumping.
Pump is air-locked
1. Consult pump installation instructions
2. 3/16" hole in discharge pipe (inside basin) is not present or is blocked. This allows
air to escape the pump volute

ECM Troubleshooting Guide
Condition Possible Cause Corrective Action
Pump does not shut off.
NOTE: Before troubleshooting
automatic control, check to see
that pump operates on
manual control. To do this,
disconnect electrical power,
remove piggyback plug from the
outlet, plug pump power cable
into outlet, turn on electrical
power, if pump operates the
switch is in failure mode.
Diaphragm switch Replace switch
Weak or hardened rubber diaphragm Replace rubber diaphragm
Plugged vent tube Clear vent tube of any obstructions
Dirt or sediment lodged between
retainer ring and rubber diaphgram
causing contact to remain closed
Clean area around rubber diaphragm
Pump is air locked
Shut power off for approximately 1 minute, then restart. Repeat several
times to clear air from pump. If system includes a check valve, a
3/16" hole should be drilled in discharge pipe approximately 2" above
discharge connections
Liquid inow matches pump capacity Larger pump required
Defective switch Disconnect switch, check with ohmmeter, open-innitive resistance,
closed-zero
Loose connection in level control wiring Check control wiring
Pump runs but does not
discharge liquid
Check valve installed backwards Check ow indicating arrow on check valve body to ensure it is
installed properly
Check valve stuck or unplugged Remove check valve and inspect for proper operation
Lift too high for pump Check rating table
Inlet to impeller plugged Pull pump and clean
Pump is air locked (See corrective action above.)
Pump does not deliver rated
capacity.
Lift too high for pump Check rated pump performance
Low voltage, speed too slow Check for proper supply voltage to make certain it corresponds to
nameplate voltage
Impeller or discharge pipe is clogged Pull pump and clean. Check pipe for scale or corrosion
Impeller wear due to abrasives Replace worn impeller
Pump cycles continually
No check valve in long discharge pipe
allowing liquid to drain back into sump Install a check valve in discharge line
Check valve leaking Inspect check valve for correct operation
Basin too small for inow Install larger basin
