Lighting and control
Chauvet Professional Cloud 9
Identify the original Cloud 9, check both liquid reservoirs and trace fan and fog channels to investigate a low-level warning without bypassing the sensors.
Ask about rental or purchase with a date, venue and route description, even without final dimensions or program.

An ultrasonic low-lying fogger that uses distilled water and approved fog fluid without dry ice or a CO2 supply. The two liquids have different reservoirs and functions. Rehearse the effect with the room’s actual airflow and floor conditions rather than assuming a guaranteed low layer or coverage area.
Plan a low-fog moment
For an entrance or scene with Cloud 9, tell us where people move, the viewing positions and the duration of the moment. The system uses distilled water and approved fluid in separate reservoirs; dry ice is not required. Layer shape and persistence depend on airflow and floor conditions, so assess the full sequence, including dissipation.
- Confirm the voltage version, circuits and level position before planning installation. Identify distilled water, suitable fluid, directional hose and drainage as system components, without mixing reservoirs or blocking outlets.
- Check permission, detection and ventilation with the venue. Review traffic routes and possible condensation: fog starting low does not guarantee it will not rise or that the floor stays dry.
- Include preparation, Ready status, trigger, stop and floor inspection in an operator-led rehearsal. Keep that result separate from approval for the full program; reassess if conditions change.
Questions to define your proposal
- What route does the entrance or dance follow?
- Is the floor level, and how will condensation be monitored?
- Which electrical version is supplied, and what access is available?
- Who supplies distilled water/fluid, operates and drains afterward?
A solution to assess with GLMedia
We can assess a Cloud 9 low-cloud moment with airflow, floor and visibility checks. Scope electrical version, access, consumables, operation and draining responsibilities. If conditions or permission prevent the effect, prepare an entrance alternative using lighting and video.
Ask about rental or purchase with a date, venue and route description, even without final dimensions or program. We can assess this system or another option and the supply, preparation, installation and operation scope to quote.
Features and connections
The 120 V version uses 2 power cords, each on its own circuit as required by the manual; the 230 V version uses 1. Have qualified personnel check the nameplate and distribution. A power connector’s IP marking does not make the complete machine weatherproof.
Operate level on a suitable floor with casters secured. Fit the directional hose and overflow/drain arrangement without kinks or blocked outlets. Drain the distilled water before transport or storage and keep the fog tank cap upward.
Prepare the system
- Confirm the model and voltage, inspect hoses, tank and cables, and allow the machine to acclimate after a temperature change. Save the existing address, timer and output settings before adjustment.
- Fill each reservoir with its specified liquid, respecting its own maximum line. Use Chauvet-approved fluid, with LLG specified for the low-lying effect; do not fill the water reservoir with fog fluid.
- Agree an attended low-output test with the venue, including detection, visibility, wet-floor checks and stopping the effect. Wait for Ready to Go Low rather than relying only on elapsed warm-up time.
Questions and troubleshooting
A low-level warning appears: distilled water or fog fluid?
Fog Fluid Low and Distill H2O Low refer to different reservoirs. A full fog-fluid tank does not establish enough distilled water.
- Read the exact message. For Fog Fluid Low inspect the fog-fluid tank, pickup hoses and level; for Distill H2O Low inspect the distilled-water reservoir and its fill line.
- Check for a kinked fluid hose and excess water. Overfilling the water tank can reduce performance; remove excess through the documented drain before continuing.
- Keep the fluid sensor enabled. If the warning remains with correct levels, stop and arrange service rather than bypassing the sensor. Failure to Heat also calls for service.
Record the exact message and check each reservoir separately before repeating a command. If levels are correct but the warning persists, refer for inspection; do not bypass sensors or add another product to force output.
Fan and fog seem reversed, or the machine starts a timer on reboot: what should I compare?
The Cloud 9 channel order is fan first, fog second. A profile copied from another hazer can reverse those functions.
- Compare the console’s first channel with Fan Speed and the following channel with Fog Output. For the complete footprint in one universe, use a starting address no higher than 511.
- Check Timer, Direct Timer and local output settings before a restart. Timer mode can persist after power is removed; press the documented STOP control and verify the stopped state in the test.
- Compare the actual revision and raw console output. The published chart contains an invalid upper DMX value; obtain a corrected map before building exact parameter ranges rather than copying that figure.
Fog rises into the room or the floor becomes wet: what is a useful check?
The visible result depends on fluid, water level, airflow and the cue. Low-lying fog does not guarantee a dry floor or permanent ground coverage.
- Verify approved low-lying fluid and correct water level. Compare a short low-output cue with the planned fan setting and hose position; do not improvise a fluid mixture from a forum report.
- Rehearse with the venue’s normal airflow and the expected activity on stage. Coordinate any ventilation change with the responsible team and check visibility beyond the effect area.
- Inspect the outlet, underside and walking surface for condensation. Stop if the surface becomes slippery or liquid leaks; protect the circulation area and investigate before repeating the cue.
Can we plan a low-cloud entrance or dance moment?
We can assess the effect around route, duration, floor, ventilation and cameras. The proposal includes a test under venue conditions: fog that starts low can rise or move with airflow and people.
- Define machine/hose positions, power for the actual version, approved water/fluid, operator and filling, testing and draining time. Operate level in a dry indoor location.
- Check floor and visibility during rehearsal; reduce or stop if condensation appears or the effect invades another scene. A light/video entrance is an alternative; a uniform layer in every room is not promised.
What if the venue forbids fog or rehearsal time is unavailable?
We can retain the intended moment through a lighting look, video background and coordinated entrance. Design the alternative around available space and resources; it is not offered as an equivalent physical cloud.
- Before quoting, discuss atmosphere, circulation and detection restrictions with the venue lead. Do not assume another gas or machine is authorized instead.
- If Cloud 9 remains in the plan, agree on testing and specified consumables. Do not adopt homemade mixtures or other systems’ fluids suggested in forums to change persistence.
What must the venue confirm before low-cloud effects are quoted?
We can assess the full solution from access to removal: level dry-indoor position, correct-version power, distilled water, approved fluid and draining. A wheeled case does not remove handling and access planning.
- Request access photos, steps or level changes, effect position and supply information. The technical lead verifies required circuits; an unused outlet or another version’s rating is insufficient.
- Assign water/consumables, filling, control, floor monitoring and draining before transport. Separate equipment hire from setup, rehearsal and operation.
- If access, floor or supply prevents proper installation, assess another position or a light/video entrance. Agree the alternative before the event rather than improvising on arrival.

| 511 | 511 | 512 |
Precautions
- Use grounded protected mains, never a dimmer or rheostat. Do not repeatedly reset a tripping breaker; stop for damaged hoses, cables, tanks or serious faults.
- Keep ventilation clear and avoid contact with the hot nozzle, including after shutdown. Water in the reservoir does not mean the machine is suitable for rain or wet locations.
- Follow the maintenance and storage instructions for the actual revision. The current manual specifies Chauvet FCQ/CF250 cleaning products; do not transfer another manufacturer’s procedure or leave the machine running dry.
