INSTALLATION INSTRUCTIONS

300 Series End Suction Pumps

Notice to Installer:  Instructions must remain with installation.

PREINSTALLATION  CHECKLIST  -  ALL  INSTALLATIONS

SEE BELOW FOR LIST OF WARNINGS

1. 

To help reduce the risk of electrical shock, a proper ground 

or control box of grounding type must be installed and pro-

tected by a ground fault circuit interrupter (GFCI) in accordance 

with the National Electrical Code and applicable local codes.

2. 

DO NOT USE AN EXTENSION CORD. Extension cords that 

are too long or too light do not deliver sufficient voltage to the 

pump motor. But more important, they could present a safety 

hazard if the insulation were to become damaged or the connection end 

were to fall into a damp or wet area. 

                      

3.  Make sure the pump’s electrical supply circuit is equipped with fuses 

or circuit breakers of proper capacity. A separate branch circuit, sized 

according to the National Electrical Code for the current shown on the 

pump name plate is recommended.

4. 

 

TESTING FOR GROUND. As a safety measure, electrical  

supply should be checked for ground using an Underwriters 

Laboratory Listed circuit analyzer which will indicate if the 

power, neutral and ground wires are correctly connected . If they are not, 

call a qualified licensed electrician.   

                      

5. 

 Installation and checking of electrical circuits and hardware 

should only be performed by a qualified licensed 

 

electrician.

6. 

 FOR YOUR PROTECTION ALWAYS DISCONNECT PUMP 

FROM ITS POWER SOURCE BEFORE HANDLING.  De-

energize the circuit at the control box. If the power point is 

out-of-sight, lock it in the open position and tag it to prevent unexpected 

application of power. Failure to do so could result in fatal electrical shock. 

7. 

 Unit must be securely and adequately electrically grounded. 

This can be accomplished by wiring the unit to a ground 

metal-clad raceway system or by using a separate ground wire 

connected to the bare metal of the motor frame or other suitable means.

8. 

 Do not put a valve in the discharge line 

without

 automatic shut-

off capability. Failure to install an automatic shut-off (pressure 

switch and tank) can allow the pump to run at no flow causing 

the pumped liquid to overheat and cause steam burns.

9. 

 Risk of electric shock. This pump has not been investigated 

for use in swimming pool areas.

10.  According to the state of California (Prop 65), this product contains chemi-

cals known to the state of California to cause cancer and birth defects or 

other reproductive harm.

NOTE: Repair and service should be performed by an Authorized Service Sta-

tion only (Consult factory).

                                            

NOTE: Pumps are designed to have a maximum static lift (suction head) of 25 

feet (vertical distance from water surface to center line of pump) see suction 

limitations.

NOTE: Pumps with the CSA CUS mark are tested to UL standard UL 778 and 

certified to CSA standard C22.2 No. 108.

1.   Check to be sure your power source is adequate to handle the 

amperage requirements of the motor as indicated on the pump or 

unit I.D. tag.

2.  All plumbing (discharge and intake lines) must be installed to meet 

local codes.

3.  Be certain the pump is completely primed before starting. Other-

wise damage may occur to the seal.

4. 

 Be careful when touching the exterior of an operating 

motor - it may be hot enough to be painful or cause injury.
