INSTALLATION

• When facing the pump, the roller assembly spins in a clockwise direction. The inlet (suction) side is located on the left side of the pumphead, and the outlet (discharge) is located on the right.
• Mount the pump in a level, dry location close to the injection point. To minimize backpressure on the system, keep the discharge tubing a short as possible.
• The recommended location is above the height of the solution tank. Mounting the pump lower than the solution tank will gravity-feed the solution and create a “flooded suction” installation. In this scenario, a shut-off valve or other device must be installed to stop the solution flow to the pump during pump servicing.
• In installations involving pressure, a check valve should be used at the point of injection to prevent potential backflow.
• DO NOT mount the pump directly over an open solution tank as chemical fumes may damage the pump.
• The voltage and frequency of the power supply must be the same as shown on the unit specification label.
• AC power must be connected to a Grounded Power Outlet (Ground Fault Circuit Interrupter GFCI). DO NOT operate the pump on an un-grounded circuit.
• Ambient air temperature should not exceed 104° F (40° C) and adequate airflow should be provided.

OPERATION

• WARNING : Tube failure may result in fluid being sprayed from the pump. Use appropriate measures to protect the operator and equipment. Tubing should be inspected periodically for tears, cracks, cuts, or abrasions.
• WARNING! Use only factory-approved tubing from the designated tubing class. Incorrect tubing can adversely affect performance or damage the pump.

Controls

3-Way Rocker Switch – All models are equipped with a 3-way rocker switch mounted on the side of the pump. The Up and Down positions turn the pump ON in the clockwise and counterclockwise direction, respectively, and the center position is OFF. Always confirm the switch is in the designated OFF position before plugging the pump into any power receptacle.

Potentiometer – All models are equipped with a potentiometer on the side of the pump which is used to regulate pump speed (output) and analog signal scaling, depending on the model. Mode Switch – For models equipped with a remote operation function, a 2-way switch is located on the back of the pump which activates and deactivates external control. LEFT=LOCAL;RIGHT=EXTERNAL.

Adjusting Flow Output

Flow output is controlled by motor speed utilizing the potentiometer. Rates are adjustable from approximately 5% to 100%. If equipped with a 4-20mA control option, pump speed will vary as the dedicated input signal changes amplitude. Please refer to Remote Operation below for more details on 4-20mA operation.

Remote Operation

Remote Start/Stop – For pump models equipped with remote start/stop, this feature operates by receiving a dry contact signal and is intended to be connected to a dry contact switch. The input has no polarity. No voltage is permitted on the input signal. The pump will activate and run while the switch is closed and deactivate and stop when the switch opens

To establish and operate this feature:

1. To activate this feature, install the pair of wires from the dry contact switch closure device into the terminal block (Figure 1)
2. Set the MODE switch to the RIGHT to enter External mode. The pump will now operate only when receiving a dry contact signal.

To return the pump local control, place the MODE switch to the LEFT, Internal mode position.

4-20mA Control – For models equipped with a 4-20mA feature, the pump’s output will vary according to the level of an incoming 4-20mA analog signal. The pump’s maximum output to the signal is scalable between 20% and 100%, as determined by the percentage setting on the potentiometer.

For standard signal models, the minimum output is approximately 5.0% at 4.8mA and increases in 1.0% increments for every .16mA until 100% of the scaled output (based upon the potentiometer setting) is reached at 20.0mA (Figure 2).

For inverted signal models, the maximum output (as established by the potentiometer setting) is reached at 4.8mA and decreases, as above, until reaching zero output at 20.0mA (Figure 3)

NOTE: Loop voltage for all models may not exceed 36VDC.

To establish and operate the analog control feature:

1. Install the two-wire lead (right side of the terminal is positive; left is negative) from the 4-20mA source into the terminal block (Figure 2)
2. Set the potentiometer to the desired scaling percentage. To operate without scaling, set the potentiometer to 100%.
3. Set the MODE switch to the RIGHT position to enter External mode. The pump will now operate only when receiving the analog signal. While in External mode, the pump canbe turned off by setting the potentiometer to 0%.

To return the pump local control, place the MODE switch to the LEFT, Internal mode position.

MAINTENANCE

Routine Inspection

The pump should be inspected on a weekly basis. Inspect for any signs of leaking and early indications of potential tube failure (e.g., swelling, cracking or discoloration). Replace any worn or damaged components immediately. Always check the chemical compatibility and pressure rating of the tubing prior to its use.

5.2 Replacing the Tubing

Pump tubing must be replaced on a regular basis. While replacement within 500 hours of run time is recommended, tube longevity is ultimately determined by many factors, including tube formulation, the chemical composition of the fluid being pumped, system back pressure, pump speed, temperature, and more. Use only factory-designated tubing. Incorrect tubing can adversely affect performance or damage the pump.

WARNING! Tubing connections may be under pressure. Always depressurize the system prior to connecting or disconnecting the pump.

WARNING! Tubing may contain chemicals. Wear protective clothing, gloves and safety glasses when working with or near the pump.

WARNING! Severe pinching of fingers can occur while installing and removing the tubing. Caution must be used to keep fingers away from rotating parts.

Tubing Removal

When facing the pump, the roller assembly spins in a clockwise direction. The inlet (suction) side is located on the left side of the pumphead, and the outlet (discharge) is located on the right.

1. Disconnect any suction and discharge tubes from the pump tube.
2. Remove the tubing retention clips.
3. With the pump running clockwise, pull down on the outlet (right) side of the tubing until the tube is out of the pump head.

Tubing Installation

Start with a section of tubing at least 14” in length. Once installed, this will result in approximately 1

1/2” extending below both sides of the pump head for fittings and attachments.

1. With the pump running, insert tube into the channel of the inlet (suction) side of the pump head. Carefully feed the tube into the pump head and through the outlet (discharge) side of the pump head and then stop the pump (Figures 3 & 4).
2. Attach the retention clips on both sides of the tube, just below the base of the pump head, to prevent tube migration during operation (Figure 5)

Pumphead Maintenance

1. Remove tubing per the Tubing Removal procedure.
2. Disconnect power to the pump.
3. Remove the screws from the pump head tabs and remove housing (Figure 6).
4. Remove the free-floating ring that rides over the roller assembly and against the pump housing (Figure)
5. Remove roller assembly by sliding it off the motor shaft (Figure 8).

Once disassembled, remove any particles or debris from the pumphead housing and roller assembly. Inspect the pump head for cracks or other damage. Ensure rollers turn freely. Be sure all cleaning solvents are removed prior to reassembly and tube replacement.

Fuse Replacement

1. Disconnect power to pump.
2. Slide out the fuse tray from the IEC socket (Figure 9).
3. Replace with one of identical size & Amperage rating.
4. Slide fuse tray back in to lock.
