Order details CSauna checks before quotation
CSA-840 is kept as a model reference, not a fixed retail SKU. Before quoting, our sales and design team match the visual direction with the buyer’s destination market, electrical standard, material preference, packing method, and order quantity. This prevents a buyer from comparing only the first unit price while missing voltage, heater clearance, wood grade, glass direction, carton or crate packing, certification support, labels, manuals, and spare-parts scope.
For importer, dealer, hotel, gym, resort, and private-label orders, the same model code can lead to different production files. CSauna records the buyer’s preferred wood species, surface finish, roof protection, glass tone, door direction, bench length, heater brand, controller location, accessory list, carton label, manual language, and loading plan before the final quotation is locked.
| Electrical route | 110-120V, 208V, 220-240V, or 380-415V can be reviewed by market when the model uses an electric heater. Heater kW, controller position, cable exit, and clearance are confirmed before production. |
|---|---|
| Material route | Red cedar, hemlock, thermo wood, spruce, pine, cedar, or project-confirmed wood can be compared by budget, outdoor exposure, surface tone, and buyer file requirements. |
| Commercial scope | MOQ is normally handled as 1 set sample order or 2 sets distributor start. Private-label work can include logo, package label, manual, SKU mix, and model revision notes. |
| Shipment file | Before handoff, CSauna confirms crate or carton packing, loading notes, destination port, accessory list, certificate support, and spare parts for the selected model direction. |
CSA-840 design and production review
CSA-840 combines a black outer frame, glazed side lights, an L-shaped bench, wraparound infrared panels, and a star-light ceiling. The drawing coordinates both bench runs, corner support, entry width, glass divisions, heater-panel distance, touchscreen, ceiling modules, ventilation, cable route, and service panels. Capacity is confirmed from the signed L-bench plan and not from the cabinet width alone.
Order-release checks for this model
The buyer confirms room access, expected users, timber and black-frame finish samples, glass thickness, door side, bench arrangement, touchscreen, lighting scenes, audio, and destination electrical standard. The emitter map separates back, side, calf, and lower zones around each bench run, with output, channel, sensor, connector, total load, and replacement reference. Supply and branch protection are approved after the complete heater and lighting load is checked. Factory inspection covers frame squareness, glass and door, both bench loads, each heating circuit, touchscreen, sensors, star lights, ventilation, finish, labels, and service access. Packing separates frame and wall panels, glass, benches, controls, wiring, ceiling modules, hardware, manuals, and spares.
| L-bench plan | Approve both bench lengths, heights, depths, supports, aisle, entry, glass sides, heater distance, cleaning route, and service access. |
|---|---|
| Wraparound heat | Map emitters by bench run and body zone; record ratings, control channels, sensors, connectors, total load, and replacement codes. |
| Star-light circuit | Separate ceiling lighting from heater circuits and confirm controls, drivers, service access, tested supply, packing protection, and spares. |
For Black-Frame Four-Person Infrared Sauna with L-Bench Layout, the final drawing, electrical schedule, packing list, labels, manuals, certificates, and spare-parts scope must carry the same CSA-840 reference.
