Introduction

This instruction manual provides essential information for the proper installation, use, and maintenance of Lesso America 839 Series Schedule 80 PVC Fittings. These fittings are designed for cold-water pressure applications, including potable water supply, irrigation, and pool/spa systems. Adhering to these guidelines will ensure optimal performance and longevity of your plumbing system.

Safety Information

Always prioritize safety when working with plumbing materials and tools. Failure to follow safety precautions can result in injury or damage to property.

• Personal Protective Equipment (PPE): Wear safety glasses, gloves, and long sleeves to protect against chemical exposure and physical injury.
• Ventilation: Ensure adequate ventilation when using PVC primer and solvent cement, as fumes can be harmful. Work in a well-ventilated area or outdoors.
• Flammability: PVC primer and solvent cement are highly flammable. Keep away from heat, sparks, and open flames. Do not smoke while working.
• Chemical Handling: Read and follow the manufacturer's instructions and safety data sheets (SDS) for all primers and cements used.
• Pressure Testing: After installation, always pressure test the system to check for leaks before putting it into full service. Start with low pressure and gradually increase.
• Local Codes: Always comply with local plumbing and building codes and regulations.

Product Overview

Installation Instructions

Proper installation is critical for a leak-free and durable connection. Follow these steps carefully:

1. Preparation:
   • Ensure the pipe ends and fitting sockets are clean, dry, and free of dirt, grease, or moisture.
   • Cut the pipe squarely and deburr both the inside and outside edges to prevent solvent cement from being scraped off during assembly and to ensure proper flow.
   • Dry fit the pipe into the fitting. The pipe should fit snugly, entering about one-third to two-thirds of the way into the socket. Mark the pipe at the depth of the fitting socket to ensure full insertion during cementing.
2. Apply Primer (if required):
   • Apply a liberal coat of PVC primer to the outside of the pipe end and the inside of the fitting socket. The primer softens and prepares the surfaces for solvent cement.
   • Allow the primer to dry for the time specified by the primer manufacturer, typically a few seconds.
3. Apply Solvent Cement:
   • Apply a uniform, heavy coat of PVC solvent cement to the outside of the pipe end.
   • Immediately apply a medium coat of cement to the inside of the fitting socket. Avoid puddling.
4. Assemble Joint:
   • While the cement is still wet, quickly insert the pipe into the fitting socket, rotating the pipe a quarter turn (90 degrees) to ensure even distribution of cement.
   • Hold the joint firmly for at least 30 seconds to prevent the pipe from pushing out of the fitting.
   • Wipe off any excess cement from the exterior of the joint.
5. Curing Time:
   • Allow the joint to cure for the recommended time before handling or pressure testing. Curing times vary based on pipe size, temperature, humidity, and type of cement. Refer to the solvent cement manufacturer's instructions for specific curing times.
   • Typically, for cold water systems, a minimum of 30 minutes to 2 hours is recommended before handling, and 6-24 hours before pressure testing.

Maintenance

Lesso America PVC fittings are designed for long-term durability with minimal maintenance. However, periodic inspection can help ensure continued optimal performance:

• Leak Inspection: Periodically check all joints for any signs of leakage, especially after initial installation and during seasonal changes.
• Physical Damage: Inspect fittings for any signs of physical damage, cracks, or discoloration, which could indicate stress or UV degradation over time. While UV resistant, prolonged direct sunlight exposure can eventually affect PVC.
• Cleaning: If necessary, clean the exterior of the fittings with mild soap and water. Avoid harsh chemicals that could degrade the PVC material.
