GENERAL SAFETY
Risk of explosion. The pump body may explode if used to boost pressure above the pressures noted on Page 3. Do not use this pump with inlet pressure greater than 70 psi (483 kPa)or less than 3 psi (20.7 kPa). If not already in the piping system, install a pressure relief valve in the pump discharge line capable of passing the full pump flow at maximum rated pressure. If local code requires installation of a pressure relief valve capable of handling the full pump flow at a pressure less than 100 psi (689 kPa), follow the code requirements.

Risk of fire or explosion. To avoid risk of fire and explosion, pump water only with this pump. Do not pump salt water, flammable liquids or chemicals. Do not  use the pump near gas pilot lights or where chemical or gas fumes are present.Use of an electric pump with liquids other than water or in an atmosphere containing chemical or gas fumes may ignite those liquids or gases and cause injury or death due to an explosion and/or fire. Pump approved liquids only with this pump.

Risk of burns. If water is trapped in the pump during operation it may turn to steam. Trapped steam may cause an explosion resulting in injury or property damage. Never run the pump with the outlet closed or obstructed.
Risk of freezing. Do not allow pump, piping, or any other system component containing water to freeze. Freezing may damage system, leading to injury or flooding. Allowing pump or system components to freeze will void the warranty.

NOTICE only service agent or qualified person should replace power cord to avoid injury.
Periodically inspect pump and system components.
Wear safety glasses at all times when working on pumps.
Keep work area clean, uncluttered and properly lighted; store properly all unused tools and equipment.

WARNING
Risk of explosion and scalding. Never run pump against closed discharge. To do so can boil water inside pump, causing hazardous pressure buildup and possible explosion.
CAUTION
Risk of flooding. Do not run the pump dry. This will damage mechanical seal and void warranty. It may cause burns to person handling pump.
CAUTION
Motor normally operates at high temperature and will be too hot to touch. It is protected from heat damage during operation by an automatic internal cutoff switch. Before handling pump or motor, stop motor and allow it to cool for 20 minutes.

INSTALLATION

PIPING – GENERAL
Support both suction and discharge piping independently at a point near the pump to avoid putting a strain on the pump housing. Start all piping AT THE PUMP.
Increase pipe diameter at both the suction and discharge by one (1) standard pipe size (minimum) to obtain desired performance and flow rate. Refer to Table I when sizing pipe for your pumping system.
NOTICE: Do not use pipe with smaller diameter on the suction side of pump.
SUCTION PIPE
Increase pipe size from pump tapping as shown in Table I.
Figure 1 depicts a recommended run of pipe and fittings for the suction side of a centrifugal pump. Please refer to this illustration when choosing pipe and fittings for your suction connection.
IMPORTANT: All connections must be air tight!

Table I – Pipe Tapping and Recommended Pipe Size Data

Figure 2 depicts conditions that are NOT DESIRABLE on the suction side of a centrifugal pump and may cause problems in flow rate and priming. Please look this illustration over carefully before choosing pipe and fittings for your suction connection.

DISCHARGE PIPING
Increase pipe size from pump tapping as show in Table I.
Figure 1 depicts a recommended run of pipe and fittings for the discharge. Install tee with priming plug as close to pump as possible. Figure 2 notes conditions that should be avoided. Please read over carefully before making discharge connection.
PRIMING THE PUMP
A pump is primed when all air in the suction line and pump volute has been evacuated and replaced with water.

To Prime:

1. Close valve in discharge line.
2. Remove priming plug from tee and fill pump and suction line with water until water is flowing back out of tee.
3. Replace priming plug.
4. Start pump and slowly open valve until desired water flow is achieved.

NOTICE: If water is not being pumped, turn off pump, close valve, and repeat steps 1 thru 4.
If pump volute is rotated as shown in Figure 1, loosen vent plug when priming to evacuate air trapped inside volute and tighten when volute is completely filled with water.

MAINTENANCE

PUMP SERVICE
This centrifugal pump requires little or no service other than reasonable care and periodic cleaning. Occasionally, however, a shaft seal may become damaged and must be replaced. The procedure as outlined below will enable you to replace the seal.
NOTICE: Pumps use mechanical seals with a rubber seat ring or a sealing O-Ring. THESE SEALS ARE COMPLETELY INTERCHANGEABLE.
NOTICE: The highly polished and lapped faces of this seal are easily damaged. Read instructions and handle the seal with care.
Some models are equipped with an impeller screw, which has a left hand thread. Before unscrewing the impeller, remove the impeller screw.

REMOVAL OF OLD SEAL

1. After unscrewing impeller, carefully remove rotating part of seal by prying up on sealing washer, using two screwdrivers (see Figure 5A). Use care not to scratch motor shaft.
2. Remove seal plate from motor and place on flat surface, face down. Use a screwdriver to push ceramic seat out from seal cavity (see Figure 5B).

INSTALLATION OF FLOATING SEAT (Figure 5C)

1. Clean polished surface of floating seat with clean cloth.
2. Turn seal plate over so seal cavity is up, clean cavity thoroughly.
3. Lubricate outside rubber surface of ceramic seat with soapy water and press firmly into seal cavity with finger pressure. If seat will not locate properly in this manner, place cardboard washer over polished face of seat and press into seal cavity using a 3/4” socket or 3/4” piece of standard pipe.
4. DISPOSE OF CARDBOARD WASHER. Be sure polished  surface of seat is free of dirt and has not been damaged by insertion. Remove excess soapy water.

INSTALLATION OF ROTATING PART OF SEAL UNIT (FIGURE 5D)

1.  Reinstall seal plate using extreme caution not to hit ceramic portion of seal on motor shaft.
2. .Inspect shaft to make sure that it is clean.
3.  Clean face of sealing washer with clean cloth.
4.  Lubricate inside diameter and outer face of rubber drive ring with soapy water and slide assembly on motor shaft (sealing face first) until rubber drive ring hits shaft shoulder.
5.  Screw impeller on shaft until impeller hub hits shaft shoulder. This will automatically locate seal in place and move the sealing washer face up against seat facing. Reinstall impeller screw (if used).
