The QTFX-B4 has an open-front fluid tank and should be operated in an upright position.
Choose a position where the bubble output is facing the area to be filled.
Ensure easy access to the rear panel and to the bubble fluid tank for refilling and cleaning.
When moving the unit around, take care not to spill the contents of the tank inside the machine.
Safety

For bubbles that glow in UV light, qtx UV bubble fluid may be used (160.576UK, 160.577UK)

Operation
The QTFX-B4 is operated by a 3-position rocker switch. The center position is off.
Press this switch to the left for constant bubble output.
Press this switch to the right for remote control of the bubble effect.
In this mode, bubbles are only produced when the switch on the remote control is pressed.
After use, switch off the machine and disconnect from the mains.
Drain the remaining fluid via the drain tap at the rear of the unit.
Rinse the bubble fluid tank with clean water and drain this also, then close the tap.
Remote control
When the remote control is connected and the rear rocker switch is pressed to the REMOTE setting, pressing the button on the remote produces bubble output on demand.
Replacing the fuse
Disconnect from the main power supply first, then remove the fuse holder part of the IEC Socket to reveal the fuse. Replace the correct fuse rating as stated on the fixture safety label or in the user guide. Lock the fuse holder cover back into place.
General maintenance
To maintain optimum performance and minimize wear, the item should be cleaned frequently. Usage and environment are contributing factors in determining frequency. As a general rule, fixtures should be cleaned after each use to avoid dust build-up and blockages, which can result in poor performances, overheating and breakages. Be sure to power off the fixture before conducting maintenance.
Unplug the fixture from power. Use a vacuum or air compressor and a soft brush to remove dust collected on external vents and internal components. Clean the external case when the fixture is cold with a dry cloth or tissue and drag dirt and grime to the outside case.
To ensure a continuing high performance it is recommended to use warm water to clean the internal tank.
