MOAS installation planning.
Plan the equipment location, utilities, remote nozzles, tubing, exhaust-fan interlock, access, and project responsibilities before installation work begins.
Project planning and coordination — not for construction
This guide helps owners and facility managers organize a MOAS project and gives engineers, architects, contractors, service personnel, and AHJs a common planning reference. It is not a construction drawing, wiring diagram, startup procedure, calibration procedure, service manual, or project approval.

Project inputs
Start with the complete commercial-kitchen exhaust path
Assemble these inputs before selecting equipment locations or coordinating utilities. A useful review starts with the full system—not only the cabinet.
Cooking and exhaust information
- Cooking equipment under the hood, including fuel type.
- Menu and cooking processes that affect the exhaust load.
- Hood arrangement, exhaust airflow, duct route, and fan arrangement.
- Discharge location and available path from the proposed nozzles to discharge.
- Nearby air intakes, occupied areas, property lines, and other sensitive receptors.
Site and project information
- Project name, address, jurisdiction, status, and anticipated schedule.
- New construction, remodel, or existing-system modification.
- Design professional, installing contractors, service contact, and AHJ contacts.
- Proposed cabinet and standard solution-container locations.
- Available electrical and cold-water utilities.
- Access for installation, inspection, refilling, startup, and future service.
System relationship
Coordinate the MOAS components as one project system
The wall-mounted cabinet supplies separate air and solution lines to two remote misting nozzles in the exhaust path. The standard solution container, utilities, fan-status relationship, and service access are coordinated with that path.
- 01
Exhaust path
Coordinate the hood, duct, fan, discharge, and available path after the nozzle location.
- 02
Two remote nozzles
Locate the misting nozzles through project-specific review; preserve access to the duct interface.
- 03
Separate tubing
Route 1/4-in. OD solution tubing and 3/8-in. OD air tubing back to the cabinet.
- 04
Cabinet and utilities
Coordinate cold water, dedicated electrical supply, standard container, ventilation, and fan interlock.
Exhaust-fan interlock intent
MOAS is intended not to operate when the exhaust fan is off. Qualified electrical personnel must coordinate the actual fan-status signal, control or relay function, dedicated supply, and authorized installation information. The planning guide does not provide relay terminals, conductor colors, line/load connections, or construction wiring.
Technical reference
Technical data for planning conversations
Keep the listed equipment rating separate from the project electrical requirement. These values describe different electrical concepts and cannot be substituted for one another.
| Item | Current planning value |
|---|---|
| Product scope | Commercial, indoor-use, permanently connected equipment |
| Listing | ETL Listed for the U.S. and Canada under Intertek Report 101453585DEN-002; the report identifies UL 197 and CSA C22.2 No. 109 |
| Listed equipment rating | 120 V, 3.5 A, 60 Hz |
| Project electrical requirement | 120 VAC, 20 A dedicated circuit for MOAS |
| Cold-water supply | 1/4 in. at 80 psi |
| Remote solution tubing | 1/4-in. OD |
| Remote air tubing | 3/8-in. OD |
| Maximum nozzle-line length | 100 ft; final routing and installation are project-specific |
| Nozzle-line conduit | 1 in. recommended; not a universal code requirement |
| Two-nozzle capacity | Up to 6,000 CFM; final configuration, nozzle location, available path, routing, startup, and calibration are project-specific |
| Cabinet | 18-gauge stainless steel; 24 in. W × 32 in. H × 8 in. D; approximately 100 lb |
| Standard solution container | 16-gauge stainless steel; 10 gal.; 24 in. W × 12 in. H × 8 in. D; approximately 20 lb empty and 100 lb full |
| Supplied container tube | 1/2 in. × 30 in.; custom lengths may be specified; 8 ft or less is documented as optimal |
| Low-solution alarm point | Below 2 gal.; operating reference, not a precision measurement guarantee |
Product listing does not establish project approval, code approval, suitability, or AHJ acceptance for a particular installation. The up-to capacity value is not a guaranteed result for every project.
Responsibilities
Coordinate the handoff before installation and startup
Installation, electrical work, startup, calibration, and service are for qualified or authorized personnel using current controlled information.
| Participant | Planning responsibility |
|---|---|
| Owner or operator | Provide current cooking, operating, site, access, and schedule information. |
| Engineer or designer | Coordinate the exhaust path, structural support, utilities, controls, access, project requirements, and AHJ review. |
| Qualified installer | Use current controlled project and installation information for the authorized work. |
| Qualified electrical personnel | Coordinate the dedicated electrical supply, fan-status relationship, and electrical work using current controlled information. |
| Authorized startup or service personnel | Perform startup, dilution adjustment, calibration, alarm checks, and service using current controlled instructions. |
| Authority having jurisdiction | Determine project acceptance under requirements applicable to the project location. |
| Molitron | Provide product information and project-specific application review. |
Safety boundary
MOAS is permanently connected electrical equipment. The cabinet contains no user-serviceable parts. Electrical-shock and hot-surface hazards may remain inside the equipment. Employer programs, qualified personnel, and current controlled instructions govern authorized work.
Scope and limitations
Final supports, anchors, clearances, access, nozzle location, duct penetration, fabrication, sealing, plumbing, controls, wiring, startup, and service require current controlled project information. Diagrams are educational and not to scale unless a scale is expressly shown.
