Setup and Installation
- Safety First: Before beginning any installation, ensure the floor scrubber is turned off, unplugged from its power source, and all moving parts have come to a complete stop. Wear appropriate personal protective equipment (PPE) such as gloves and eye protection.
- Drain Recovery Tank: If the recovery tank contains liquid, drain it completely into an appropriate receptacle before proceeding.
- Locate Existing Hose: Identify the current drain hose connection point on your Tennant floor scrubber's recovery tank.
- Remove Old Hose: Carefully disconnect the old drain hose. This may involve loosening a hose clamp or unscrewing a fitting. Note the orientation and connection method for reassembly.
- Inspect Connection Point: Clean any debris or residue from the machine's drain outlet to ensure a secure and leak-free connection for the new hose.
- Install New Hose: Attach the new 1043538 drain hose to the machine's drain outlet. Ensure the connection is snug and secure. If a hose clamp was present on the old hose, transfer it or use a new one to firmly secure the new hose.
- Verify Connection: Gently tug on the hose to confirm it is securely attached and will not detach during operation or draining.
Operating Instructions
The drain hose is used to empty the recovery tank of your floor scrubber. Follow these steps for proper operation:
- Position the Scrubber: Move the floor scrubber to a designated drainage area, such as a floor drain or a large utility sink.
- Prepare for Drainage: Ensure the end of the drain hose is positioned correctly to direct the wastewater into the drain or receptacle.
- Open Drain Valve: If your drain hose features a cap or valve, open it to allow the wastewater to flow out of the recovery tank. Some models may have an integrated cap on the hose itself, while others might have a separate valve on the tank.
- Monitor Drainage: Allow the tank to drain completely. Monitor the flow to ensure there are no blockages or leaks.
- Close Drain Valve: Once the tank is empty, close the drain cap or valve securely to prevent spills during machine operation.
- Secure Hose: Return the drain hose to its stored position on the machine, if applicable, to prevent it from dragging or getting damaged during transport or operation.
Maintenance
Regular maintenance of the drain hose is crucial for its performance and longevity.
- Rinse After Use: After each use, especially when draining dirty water, rinse the inside and outside of the drain hose with clean water to remove any debris or chemical residues. This prevents buildup and odors.
- Inspect for Damage: Periodically inspect the entire length of the hose for signs of wear, cracks, punctures, or kinks. Pay close attention to the connection points and the corrugated sections.
- Check Clamps/Fittings: Ensure all hose clamps and fittings are tight and secure. Loose connections can lead to leaks.
- Proper Storage: When not in use, store the hose in a manner that prevents kinking or crushing. Avoid exposing it to extreme temperatures or direct sunlight for prolonged periods, as this can degrade the material.
- Replace When Worn: If significant wear or damage is observed, replace the drain hose promptly to prevent leaks and ensure efficient operation of your floor scrubber.
Troubleshooting
Below are common issues and their potential solutions related to the drain hose.
- Slow or No Drainage:
- Check if the drain cap or valve is fully open.
- Inspect the hose for kinks or blockages. Remove any debris that may be obstructing the flow.
- Ensure the recovery tank's internal filter (if applicable) is clean and not clogged.
- Leaks from Hose or Connections:
- Verify that all hose clamps and fittings are securely tightened.
- Inspect the hose for cracks, tears, or punctures. If damaged, the hose must be replaced.
- Check the seal around the drain outlet on the machine.
- Hose Detaches During Draining:
- Ensure the hose is properly secured with a clamp at the machine's drain outlet.
- Avoid excessive pulling or tension on the hose during drainage.
