- Ensure proper ventilation in the installation area.
- Do not operate the pump if it is damaged or malfunctioning.
- Refer to chemical manufacturer's safety data sheets (SDS) for specific handling instructions.
5. Setup and Installation
5.1 Unpacking
Carefully remove the pump from its packaging. Inspect the unit for any signs of damage that may have occurred during shipping. Report any damage to your supplier immediately.
5.2 Mounting
- Select a stable, level surface for mounting the pump.
- Ensure the mounting location allows for easy access for maintenance and adjustments.
- Secure the pump using appropriate fasteners through the mounting holes provided on the base.
5.3 Tubing Connections
- Connect the suction tubing from the chemical supply tank to the inlet port of the pump head. Ensure the tubing is securely fastened to prevent air leaks.
- Connect the discharge tubing from the outlet port of the pump head to the injection point in your system.
- Ensure all connections are tight and leak-free. Use appropriate fittings for your tubing size (1/4 inch).
- Verify that the chemical being pumped is compatible with the pump head tubing material.
5.4 Electrical Connection
Connect the pump to a grounded 120V/60Hz power supply. Ensure the power source matches the pump's requirements. Do not use extension cords unless absolutely necessary and ensure they are rated for the pump's power draw.
6. Operating Instructions
6.1 Priming the Pump
The Stenner 45MHP10 is self-priming. To prime the pump:
- Ensure the suction tubing is submerged in the chemical solution.
- Turn on the pump. The pump will draw liquid and expel air from the system.
- Allow the pump to run until a steady flow of chemical is observed at the discharge point.
6.2 Adjusting Flow Rate
The pump features an adjustable output dial. To adjust the flow rate:
- Locate the adjustment dial on the side of the pump head (refer to Figure 1).
- Rotate the dial to the desired setting. Higher numbers typically correspond to higher flow rates.
- Monitor the actual chemical dosage to fine-tune the setting as needed for your application.
6.3 Normal Operation
Once primed and the flow rate is set, the pump will operate continuously as long as power is supplied and chemical is available. Regularly check the chemical supply and pump performance.
7. Maintenance
Regular maintenance ensures optimal performance and extends the life of your Stenner pump. Always disconnect power before performing any maintenance.
7.1 Tubing Replacement
The peristaltic tubing is a wear item and should be replaced periodically, depending on usage and chemical compatibility. Signs of wear include reduced flow, leaks, or cracking.
- Disconnect power to the pump.
- Carefully remove the pump head cover.
- Remove the old tubing from the rollers and ports.
- Install new, genuine Stenner replacement tubing, ensuring it is properly seated around the rollers.
- Reattach the pump head cover and reconnect power.
- Prime the pump as described in Section 6.1.
7.2 Cleaning
Periodically inspect the pump exterior and connections for any chemical residue or buildup. Clean with a damp cloth. Avoid using harsh chemicals that may damage the pump's materials.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not running | No power; Motor failure | Check power connection and circuit breaker. If power is present, contact support. |
| No chemical flow | Empty chemical tank; Air leak in suction line; Clogged tubing; Worn peristaltic tubing | Refill tank. Check all suction connections for tightness. Clear any blockages. Replace peristaltic tubing. |
| Inconsistent flow | Air in system; Worn peristaltic tubing; Incorrect adjustment dial setting | Re-prime the pump. Replace peristaltic tubing. Verify adjustment dial setting. |
