UNPACKING AND INSPECTION

Handle with care. Check the items received against the packing list to be sure that all equipment has been received. Inspect the pump for shipping damage. If any is found, file a claim with the carrier immediately.

GENERAL SAFETY INFORMATION

READ AND FOLLOW SAFETY INSTRUCTIONS!

This is the safety alert symbol. When you see this

symbol on your pump or in this manual, look for one of the following signal words and be alert to the potential for personal injury.

Warns about hazards that will cause seri-

ous personal injury, death, or major property damage if ignored.

Warns about hazards that can cause serious

personal injury, death, or major property damage if ignored.

Warns about hazards that will or can cause

minor personal injury or property damage if ignored.

NOTE: Indicates special instructions which are important but not related to hazards.

NOTE: Install the pump in the vertical position only. Installing the pump in any other position will void the warranty.

NOTE: This unit is not designed for applications involving salt water or brine! Use with salt water or brine will void warranty.

1. To avoid serious injury and/or property damage, read

these rules and instructions carefully.

2. Check your local codes before installing. You must

comply with their rules.

3. Vent any sewage or septic tank according to local

codes.

4. Do not install the pump in any location classified as hazardous by National Electrical Code, ANSI/NFPA 70-1984.

5. The pump can run hot. To avoid burns when servicing the pump, allow it to cool for 20 minutes after shut-down before handling it.

6. Do not run the pump dry. Dry running can overheat the pump and will void the warranty.

7. The pump is permanently lubricated. Check the oil level in the seal plate periodically. Check for water in the oil in the seal plate. See instructions under "Operation/Lubrication”, Page 4.

Hazardous voltage. Can shock, burn, or kill. During operation the pump is in water. To avoid fatal shock, proceed as follows if the pump needs servicing:

Electrically ground the pump to a suitable ground such as a grounded water pipe, a properly ground-

ed metallic raceway, or a ground wire system.

Do not remove cord or strain relief.

Do not connect conduit to pump.

Do not lift the pump by the power cord (See ‘Cord Lift Warning’, below).

A. Ground the pump according to all applicable codes

and ordinances.

B. Disconnect the power to the outlet box or circuit

breaker before servicing.

C. To reduce the risk of electric shock, take care when

changing fuses or resetting the circuit breaker. Do not stand in water when working on the control box or with the circuit breaker.

D. This pump is intended for permanent connection only.

Provide a strain relief at the control box for the power supply cord connection to box. All control components must be UL or CSA listed and suitable for end use application. Only qualified personnel should install the pump and associated control equipment.

Risk of electrical shock and fire.

1. Attempting to lift or support the pump by the power cord can damage cord and cord connections, expose bare wires, and cause a fire or electrical shock.

4. Use handle on top of pump for all lifting or lowering of pump. Disconnect the power to the pump before doing any work on it or attempting to remove it from the pit.

3. Lifting or supporting the pump by the power cord will void the warranty.

Risk of electrical shock. Can burn or kill. Do not lift pump by

power cord.

INSTALLATION

This pump may be installed on a guide-rail lift-out system for ease of inspection and service. Guide rails allow removal of the pump without disturbing the piping or requiring personnel to enter the wetwell (most codes require protective equipment and training before entering the wetwell). If installed with a guide-rail system, place the pump opposite the influent opening to prevent stagnant areas where solids can settle.

Install the pump on a hard, level surface (cement, asphalt, etc.). Never place the pump directly on earth, clay, or gravel surfaces. The basin must be at least 18" (458 mm) in diameter and 30" (762 mm) deep.

The pump’s feet are shipped loose in the crate with the pump. Install them before putting the pump in the pit.

Pump Mount

Install the pump as a free standing unit.

Set the pump on the floor of the basin. Install a pipe union in the discharge piping to allow removal for servicing.

Piping

The piping must not be smaller than the pump discharge.

ELECTRICAL

Hazardous voltage. Can shock, burn, start a fire, or kill. When installing, operating, or servicing this pump, follow electrical safety instructions below.

Only trained service personnel should install or service this pump.

1. DO NOT splice the power cord.

2. DO NOT handle or service the pump while it is connected to the power supply.

3. DO NOT operate the pump unless it is properly grounded. Wire the pump directly into a grounded terminal block in an automatic float or pump controller box for automatic operation. Connect the pump according to all applicable codes. For continuous operation, wire the pump directly into the switch box.

4. Incorrect voltage can cause a fire or seriously damage the motor and voids the warranty. Make sure that the frequency and voltage shown on the nameplate corresponds to the frequency and voltage of the electrical supply. The supply voltage must be within + 10% of the nameplate voltage. If in doubt consult a licensed electrician.

5. The pump rotation must be clockwise ( – viewed from the top of the pump). NEVER operate it in reverse.

6. Connect the pump to its own circuit with nothing else on the circuit. See Table I, Page 4, for fuse or circuit breaker sizes. See Figures 2 and 3 for 230/460 Volt 3 phase connection diagrams. Use a control panel sized to match the pump. Refer to Control panel installation instructions for wiring connection information.

7. Install the pump in accordance with all electrical codes that apply. Install a fused disconnect switch or circuit breaker in accordance with local codes.

8. If a three phase unit runs backwards, interchange two of the three power supply wires to reverse the motor’s direction of rotation.

Control Panels

Risk of electric shock. Ground pump and motor before connecting controls or power supply. Adhere to local electrical codes governing pump and control installations.

A control panel is not included with the pump.

Install simplex or duplex control panel (purchase separately) for proper pump operation. A full range of controls and switches is listed in our catalog.

If a Sta-Rite control panel is not used, install a control panel with circuit breaker or fused disconnect as required by local code. Use magnetic starters with ambient compensated overload protection. Three phase units require three line protection; single phase units require only one line protection. Inadequate protection voids the warranty.

Control Panel Overload Adjustment – Three Phase

NOTICE: See your control panel installation and operat-

ing instructions before adjusting overload setting.

Set the overload protective device to the nameplate full load current.

Size the overload protective device so that the trip current is 115% of the nameplate full load current.
