Installation Notes

⚠️ Pump must be installed below bath water level – Self-draining design requires gravity feed for proper drainage

⚠️ Never run the pump dry – Causes immediate seal damage and motor overheating

⚠️ Ensure proper bonding to earth – All metal components must be equipotentially bonded

⚠️ Check air switch tubing – Pneumatic line must be free from kinks or blockages

⚠️ Use appropriate sealant – Thread sealant tape on all threaded connections

⚠️ Test before enclosing – Run pump and check for leaks before completing cabinet installation

Pneumatic Air Switch Installation

The pump features integrated pneumatic activation:

Air button mounts on bath surround above water level
Flexible tubing connects button to pump air switch
Tubing must be continuous with no joints or damage
Maximum tubing length typically 3 metres
Ensure tubing routing avoids heat sources and sharp bends

🔧 Maintenance Guide

Routine Maintenance Schedule

Motor ventilation check	Quarterly	Ensure air vents free from dust and debris
Drain function verification	Quarterly	Confirm water drains completely after use
Professional electrical inspection	Annually	Check connections, earth continuity, RCD function

Operating Best Practices

💡 Run regularly – Operate whirlpool system at least weekly to prevent seal drying and bacterial growth

💡 Clean the bath – Use appropriate whirlpool bath cleaner monthly to prevent biofilm buildup

💡 Drain completely – Ensure self-drain function operates correctly after each use

💡 Monitor temperature – Avoid operating with excessively hot water (above 40°C) for extended periods

❓ Frequently Asked Questions

Q: What horsepower is this pump? A: The Superflow Plus delivers 1.0HP motor power with 1.13kW electrical output, suitable for medium-sized whirlpool bath systems.

Q: Will this pump fit my whirlpool bath? A: This pump features 63mm connection diameter with 1.5″ male buttress thread unions. Check your existing pump connections match these specifications. It’s designed for Spa-Tec Superflow systems but may fit other configurations with matching plumbing.

Q: What voltage does this pump require? A: 220-240V at 50Hz – standard UK mains supply. All electrical installation must be performed by a qualified electrician with proper RCD protection.

Q: Is this a single or dual speed pump? A: Single speed only, running at 2820 RPM. This provides consistent jet pressure without speed variation controls.

Q: How does the pneumatic activation work? A: An air button mounted on your bath surround sends an air pulse through tubing to the pump’s integrated air switch. Pressing the button toggles the pump on and off without any electrical contact near the water.

Q: What is self-draining and why does it matter? A: Self-draining pumps automatically empty residual water when the system stops. This is essential for hygiene in whirlpool baths, preventing stagnant water and bacterial growth in the pump and pipework between uses.

Q: Can I use this in a hot tub? A: This pump is designed for intermittent whirlpool bath use, not continuous hot tub circulation. It lacks the duty rating and thermal protection required for 24/7 hot tub operation.

Q: What warranty is included? A: Manufacturer’s standard 1-year warranty. Extended warranty options may be available – contact Parts4Tubs for details.

Q: Are spare parts available? A: Individual spare parts are not available for this pump model. In the event of seal failure or internal component wear, complete pump replacement is recommended.

Q: My pump isn’t starting – what should I check? A: First verify the air button tubing isn’t kinked, disconnected, or damaged. Check the RCD hasn’t tripped. If the pneumatic system appears intact, the pump may require replacement.
