Lay-Z-Spa Aruba Signature AirJet (Grey, 170cm)

How long does it take to heat the water to 40°C?

The heating time depends on starting water temperature and ambient conditions. From cold tap water (around 15°C), expect 12-24 hours to reach 40°C. The compact 800-litre capacity heats faster than larger spas. In warmer weather or with warmer starting water, heating time reduces significantly. The pump heats approximately 1-2°C per hour.

Can the Aruba be used during winter months?

Yes, the Freeze Shield technology specifically protects the pump and liner from cold weather damage. The system automatically activates heating when temperatures drop to prevent freezing. However, in very cold conditions, heat loss may exceed heating capacity, so the cover should be used when not in use to maintain temperature efficiently.

How many people can realistically fit in this spa?

The 170cm diameter comfortably seats 2 adults with plenty of space to move and relax. Three adults fit reasonably well, though space becomes more limited. Four people would be quite cramped. For regular entertaining, consider this primarily a couples' spa with occasional capacity for a third person.

What maintenance is required for the Aruba?

Regular chemical balancing is essential - test and adjust chlorine, pH and alkalinity levels using test strips. Change the filter cartridge after the first 24 hours, then weekly with frequent use. Clean debris from the water surface daily. Drain and refill completely every 6-8 weeks depending on usage frequency and bather load.

How much does it cost to run the spa daily?

Running costs vary by usage and local electricity rates. The pump typically uses 1.5kW when heating and 0.5kW for filtration. Expect £2-4 per day for heating and maintaining temperature with regular use. Using the timer function and cover when not in use significantly reduces energy consumption.

Is professional installation required?

No professional installation needed. The spa inflates in minutes using the included pump. Simply choose a level surface, lay protective matting, inflate, fill with water and connect to a standard 13-amp socket with RCD protection. The entire setup process takes 2-3 hours including filling time.

What chemicals are needed and where do I buy them?

You'll need chlorine granules or tablets, pH increaser/decreaser and alkalinity increaser. The ChemConnect dispenser evenly distributes chlorine. Purchase spa chemicals from pool suppliers, garden centres, or online. A starter chemical kit costs around £20-30 and lasts several weeks depending on usage.

How do I drain the spa when needed?

The spa includes a drain plug at the bottom, but gravity drainage is slow due to the 800-litre capacity. Many owners invest in a submersible pump for faster emptying. Position the spa where drainage water can flow away safely, avoiding flooding neighbouring properties or overwhelming drainage systems.
