Blu 09 9 (White, 9000 BTU)

What room size can the Blu 09 9 effectively cool?

The unit is designed for rooms up to 20 square metres. However, cooling effectiveness depends on factors like ceiling height, insulation quality, sun exposure and heat sources. In well-insulated rooms with standard 2.4m ceilings, it can maintain comfortable temperatures even during hot weather. Larger or poorly insulated spaces may require longer cooling times or may not reach target temperatures efficiently.

How much electricity does this air conditioner consume?

The unit draws 1010W of power input with a rated current of 5.3A at 240V. Running costs are approximately 30-35p per hour based on current UK electricity rates. The energy class A rating indicates good efficiency compared to similar capacity units. Using the timer function and switching to fan mode after initial cooling can reduce energy consumption significantly.

Does the unit require permanent installation or window modifications?

No permanent installation is needed. The unit works straight from the box with the included window kit. The exhaust hose connects to a window adapter that seals using velcro strips without drilling or permanent fixtures. The system works with both inward and outward opening UK casement windows. Setup typically takes 20 minutes including window seal installation.

How loud is the Blu 09 9 during operation?

The sound pressure level measures 49-53 dBA, which is quieter than many portable air conditioners. This is comparable to moderate rainfall or quiet conversation levels. While not silent, most users find it acceptable for bedroom use. The noise level remains consistent across all fan speeds and cooling modes, with occasional water trickling sounds during operation.

What maintenance does the self-evaporating system require?

The self-evaporating function handles most water removal automatically by recycling condensed water to cool coils and evaporating excess through the exhaust. Manual water removal is rarely needed during normal operation. However, if the unit is moved or tilted, small amounts of water may leak. The system includes continuous drainage capability for extended use periods.

Can I use an extension lead with this air conditioner?

The manufacturer strongly advises against using multiway extension leads as this can cause whining noise and affect performance. If an extension is necessary, use only a single gang heavy duty extension lead rated for the 1010W power consumption. The unit comes with a 2m power cable which should reach most wall sockets when positioned correctly.

What's included in the box and what do I need to buy separately?

The package includes the air conditioner unit, remote control, 1.5m expandable exhaust hose, window seal kit for UK casement windows, user manual and hose connection components. You need to provide AA batteries for the remote control. No additional window adapters or installation tools are required for standard UK windows.

Does this model provide heating as well as cooling?

No, the Blu 09 9 is cooling-only and does not include heating functionality. It operates in three modes: cool (full air conditioning), fan (air circulation without cooling) and dehumidifier (moisture removal). For year-round climate control, you would need a separate heating solution during winter months.
