During system operation, pump must be submerged at all times.
Pipe joint compound can cause cracking in plastics. Use only
teflon tape when sealing joints in plastic pipe or connecting
pipe to thermoplastic pumps.
Warranty is void in the following conditions:
• Water is highly corrosive.
• If entrained gas or air present in water being pumped
reduce the flow and cause cavitation (which can damage
the pump).
• Pump has been operated with discharge valve closed
(severe internal damage will result).
ELECTRICAL
Wiring/Grounding
Hazardous voltage. Can shock, burn, or cause
death. Permanently ground pump, motor and control box
before connecting power supply to motor.
Ground pump and motor in accordance with all codes and
ordinances that apply. All wiring must meet National Electrical
Code and Canadian Electrical Code (whichever applies). Use
copper ground wire at least as large as wires carrying current
to pump.
Pump is supplied with copper ground wire. Use only copper
wire for connections to pump.
Permanently ground pump before connecting power cable to
power supply. Connect ground wire to approved ground first,
then connect to equipment being installed.
Do not ground to a gas supply line.
Float switches or any other approved motor control must
match motor input in full load amperes.
For more information, contact your local code officials.
Installation Wiring Instructions
Pump has two power supply wires (Red/Black) and one ground
wire (Green).
Fasten power supply wire leads securely to control panel;
leave 4-5" of slack in leads at this point. Securely fasten leads
to plastic pipe within 6" of the pump discharge section.
NOTICE:
To avoid dropping pump or damaging wires or
splices,
NEVER
allow pump wires to support weight of pump.
EFFLUENT APPLICATIONS
Pumps designed and tested for effluent applications must meet
the following:
Risk of electrical shock.
Do not remove or alter
cord. Do not connect conduit to pump.
1. Only qualified personnel should install the pump and
associated control equipment.
2. Vent sewage tank according to local code.
3. Do not install pump in any location classified as haz-
ardous by National Electrical Code, ANSI/NFPA 70-1984.
4. These pumps are intended for permanent connection only.
Provide strain relief at control panel for power supply cord
connection to box. All control components must be UL
listed and suitable for end use application.
5. Do not pump flammable liquids, strong caustics, or strong
acids with this pump.
PUMP INSTALLATION
1. To prevent dropping pump, lower it by the drop pipe, not
by the cables. The electrical cables will not hold the pump
weight.
2. Discharge outlet is 1-1/4" NPT threaded.
NOTICE:
If installing external check valve, hold discharge
with pipe wrench to prevent loosening discharge in shell.
3. If pump is to be operated with an open discharge, a dis-
charge valve
must be installed
. Before startup, open this
valve about 1/3 open. Start pump.
Slowly
open valve until
the desired flow rate is reached. Final setting must be with-
in pump’s recommended operating range.
OPERATION
1. The pump must be submerged at all times during normal
operation.
Do not run pump dry.
2. Make sure that the float switches are set so that the pump
stops before the pump runs dry or breaks suction. If neces-
sary, adjust float switches to achieve this.
3. The motor bearings are lubricated internally. No mainte-
nance is required or possible on the pump.
