Parts compatibility resource
Spare parts create support problems when a dealer only asks for a part name. The safer method is to match model, heater, controller, voltage, dimensions, connector, finish, and batch evidence before promising compatibility.
Match by model and part
Use the CSA model code, part family, and visible label before confirming a replacement.
Check risk before shipping
Electrical, glass, heater, controller, and structural parts need stronger evidence than small trim parts.
Keep a compatibility record
A matrix helps dealers avoid repeated mistakes across showroom, distributor, and commercial projects.
Compatibility check matrix
Use this table before confirming a spare part. It reduces wrong shipments and makes the dealer look more professional with buyers.
| Part family | Must match | Evidence required | Risk if wrong |
|---|---|---|---|
| Heater | kW, voltage, phase, controller type, heater dimensions, safety clearance, certification scope. | Heater label, controller photo, order record, wiring note if safe. | Electrical risk, poor performance, failed approval, warranty dispute. |
| Controller | Controller model, sensor type, heater compatibility, cable connector, voltage, display size. | Screen photo, controller back label, connector photo, heater label. | No operation, error code, unsafe mismatch, support delay. |
| Glass and door | Door size, hinge side, glass thickness, handle type, frame shape, gasket profile. | Wide door photo, measurement photo, hinge close-up, model code. | Fit failure, glass stress, shipping damage risk. |
| Bench and interior wood | Bench length, support style, wood type, finish, fastener position, room size. | Interior photo, measurement, underside photo, product page. | Poor fit, unstable seating, wrong finish. |
| Sensor and cable | Sensor model, plug type, cable length, controller compatibility, installation location. | Sensor photo, connector photo, controller model. | Incorrect temperature reading or controller error. |
| Trim, handle, gasket | Profile, size, color/finish, fastening method, door or panel version. | Close-up photo with ruler and wider context. | Cosmetic mismatch or repeated adjustment. |
Dealer compatibility worksheet
This worksheet gives a parts coordinator enough information to approve, reject, or ask for more evidence.
| Field | Entry needed | Example | Approval note |
|---|---|---|---|
| Requested part | Part name, quantity, reason for replacement. | Door gasket, 2 sets, wear after commercial use. | Confirm whether normal wear or warranty route. |
| Product model | CSA model code and product page. | CSA-184, indoor infrared room. | Use public catalog code for communication. |
| Original part evidence | Photo, label, dimensions, connector, side, orientation. | Gasket profile and door frame photo. | Photo must show context and close-up. |
| Replacement requirement | Same part, upgraded part, alternative part, emergency temporary part. | Same gasket profile preferred. | Do not substitute without buyer approval. |
| Compatibility decision | Approved, conditional, needs factory review, not compatible. | Needs factory review due to controller difference. | Record who approved the decision. |
| Shipment note | Packing method, label, model reference, included screws or accessory bag. | Label part bag with CSA-184 door gasket. | Avoid warehouse mixing. |
High-risk part approval levels
Some parts can be approved by the dealer. Others need factory or electrician review before shipment.
| Risk level | Parts included | Who can approve | Extra evidence |
|---|---|---|---|
| Low | Handle, trim, small gasket, cosmetic cover, loose accessory. | Dealer parts coordinator. | Photo with ruler and model code. |
| Medium | Bench board, hinge, door gasket, wood panel, lighting strip. | Dealer plus installer if fit affects safety. | Wide photo, measurements, installation context. |
| High | Heater, controller, sensor, wiring-related cable, glass, structural bench support. | Factory technical review or qualified site professional. | Labels, voltage, connector, dimensions, site condition, stop-use note if needed. |
| Commercial account | Any repeated replacement in hotel, gym, spa, resort, or chain project. | Dealer manager plus factory contact. | Case history, maintenance log, quantity, buyer impact. |
Compatibility record table
Keep the compatibility result for future dealer training and repeat orders.
| Record item | What to save | Where it helps | Review cycle |
|---|---|---|---|
| Approved match | Model code, part code, evidence, approver, date. | Faster repeat shipment. | Review when model changes. |
| Rejected match | Why the part was not compatible. | Avoids repeated wrong requests. | Review during dealer training. |
| Conditional match | Condition required before use. | Clarifies buyer risk. | Review after installation. |
| Part photo library | Clear photos of labels, connectors, profiles, sizes. | Dealer self-service support. | Update quarterly. |
| Batch or version note | Which product version or shipment uses the part. | Private-label and commercial projects. | Update after each model revision. |
Team workflow for using this worksheet
The worksheet is most useful when it becomes part of the dealer operating routine, not a one-time document. Assign a clear owner, collect evidence before promising a solution, and review repeated cases so the next order, spare-parts kit, or buyer handover file improves.
| Workflow step | Owner | What to do | Output |
|---|---|---|---|
| Open the case | Dealer service desk | Create the record with buyer type, CSA model code, site, symptom, priority, and requested result before technical review starts. | A complete first ticket or worksheet row. |
| Collect evidence | Buyer, dealer, installer, or warehouse | Attach the minimum evidence listed in the table: photos, screenshots, labels, dimensions, service notes, or stock records. | A reviewable evidence folder instead of scattered chat images. |
| Decide the route | Dealer manager or parts coordinator | Classify the case as buyer guidance, installer review, warehouse check, part compatibility, warranty review, or factory technical support. | A clear owner and next action. |
| Close and learn | Dealer service desk | Record the final action, part used, credit or replacement decision, buyer notice, and any change needed for future stock or handover notes. | A closed case that improves future dealer operations. |
Spare-part master data fields
A dealer parts library should not depend on memory or a photo album. Each spare part needs a stable record that connects the part to the model code, version, evidence, approval level, and packing note. This is especially important for heaters, controllers, glass, door hardware, lighting, and private-label projects.
| Master data field | What to record | Used by | Example entry |
|---|---|---|---|
| Part family and function | Heater, controller, sensor, glass, hinge, handle, gasket, bench board, LED strip, speaker, fastener, or trim. | Dealer service desk and warehouse. | Door gasket, seals glass-front outdoor cabin door. |
| Compatible model range | CSA model codes, product URL, model revision, door direction, heater route, or private-label version. | Parts coordinator and sales support. | CSA-641 to CSA-649 curved outdoor cabin family, right-hinge variant only. |
| Critical dimensions | Length, width, thickness, hole spacing, connector shape, glass thickness, voltage, kW, or phase. | Installer, electrician, and factory technical reviewer. | Handle hole spacing 160 mm; 8 mm tempered glass; black finish. |
| Evidence required before approval | Label photo, close-up with ruler, wide product photo, controller screenshot, wiring note if safe, or order record. | Dealer, buyer, installer, and factory. | Old controller label, connector photo, heater label, product model page. |
| Approval level | Dealer approval, installer confirmation, factory technical review, or qualified electrical review. | Service manager. | Factory review required because controller and heater are electrical parts. |
| Packing and label note | Bag label, carton mark, screws included, gasket orientation, fragile mark, or separate accessory box. | Warehouse and logistics team. | Pack hinge set with screws; label as CSA-644 left door hinge kit. |
| Version control | First order used, latest order used, replaced part number, discontinued note, and alternative route. | Dealer training and reorder planning. | Old LED driver discontinued; new driver requires connector adapter after 2026 Q2. |
Substitution approval matrix
Sometimes the original part is not available, or a buyer wants an upgraded part. A substitute should be approved only when the risk is understood and the buyer, dealer, installer, or factory has the correct evidence.
| Substitution type | Allowed when | Evidence needed | Approval condition |
|---|---|---|---|
| Same specification, different batch | The part dimensions, connector, finish, and function match the original product version. | Old and new label photos, dimension photo, model code, and order record. | Dealer can approve low-risk parts; factory confirms high-risk electrical or glass parts. |
| Cosmetic finish alternative | The buyer accepts a visible finish difference and the part does not affect safety or installation. | Color/finish photo, buyer approval note, model context photo. | Record as accepted variation before shipment. |
| Upgraded part | The upgraded part is compatible with the existing model, electrical route, and installation condition. | Specification sheet, connector or dimension check, installer note when relevant. | Factory technical review for heater, controller, glass, sensor, or structural parts. |
| Temporary service part | A commercial site needs a short-term service route while the exact part is being prepared. | Stop-use or limited-use note, service manager approval, buyer acknowledgment. | Use only with a written follow-up plan and final exact replacement schedule. |
| Not acceptable | Voltage, phase, connector, glass thickness, hinge side, load-bearing support, or safety clearance does not match. | Mismatch evidence and rejection reason. | Do not ship as a substitute; open a factory review case. |

This is the difference between a blog post and a working B2B resource: the buyer can read it, the dealer can use it, and the factory can respond with fewer repeated questions.
Parts matching appendix
Spare-parts compatibility evidence pack
Compatibility should be approved from evidence, not from a part name. The same part label can be misleading if voltage, connector, model version, or dimensions changed.
Part-family evidence requirements
| Part family | Evidence to collect | Compatibility risk | Approval owner |
|---|---|---|---|
| Heater and controller | Heater label, controller label, voltage, connector, wiring path if safe, model code, order date. | Wrong voltage, wrong controller protocol, certification mismatch, unsafe replacement. | Factory technical review plus qualified local professional where electrical work is involved. |
| Glass and door parts | Door width/height, glass thickness, hinge side, frame photo, gasket profile, opening direction. | Wrong side, stressed glass, poor seal, shipping damage after wrong packing. | Dealer technician or factory review before shipment. |
| Bench and interior boards | Interior dimensions, wood species/finish, support position, fastener location, underside photo. | Poor fit, weak support, finish mismatch, repeat installation work. | Dealer service desk plus installer if site fitting is required. |
| Trim, handle, gasket | Close-up with ruler, wide photo for context, color/finish note, old part condition. | Cosmetic mismatch or wrong profile but low safety risk. | Dealer parts coordinator can approve if evidence is clear. |
Compatibility decision log
| Decision | When to use | Message to buyer/dealer | Record to keep |
|---|---|---|---|
| Approved match | Evidence confirms model, version, dimensions, and connector. | Part can be supplied for the stated model and record. | Approved row with photos and approver name. |
| Conditional match | Part may fit only if buyer confirms one missing measurement or version detail. | Ask for the missing measurement before shipment. | Open condition and deadline. |
| Factory review required | Electrical, glass, controller, heater, or repeated failure case. | Do not promise shipment until technical review is complete. | Case file and reviewed evidence. |
| Not compatible | Evidence shows different model, part version, voltage, or dimensions. | Explain mismatch and request correct model or new evidence. | Rejected row so the same error is not repeated. |
How dealers should use this appendix
- Keep the approved compatibility row with the order file so repeat shipments are faster.
- Use public CSA model codes in every parts message; do not rely on vague buyer descriptions.
- A photo library of labels, connectors, profiles, and dimensions becomes a dealer training asset over time.
Editable worksheet note: Buyers or dealers can message CSauna for a clean spreadsheet version of this appendix. The request can be for service planning, dealer training, project handover, or buyer documentation and does not need to be a quotation request.
Compatibility examples
Compatibility case pack for high-risk sauna parts
Compatibility review is not just a yes/no table. Dealers need examples that show when to approve, when to hold, and when to route the case to technical review before shipping a replacement part.
High-risk compatibility scenarios
| Scenario | Risk | Required check | Decision |
|---|---|---|---|
| Controller looks similar but connector differs | Wrong controller can fail or create unsafe installation work. | Compare old/new controller labels, connector shape, model version, voltage, and order date. | Hold shipment until factory technical review confirms the exact version. |
| Glass panel size is close but hinge side differs | Panel may not fit or may be stressed after installation. | Confirm door swing, hinge side, glass thickness, frame photo, and opening measurement. | Do not approve from approximate dimensions only. |
| Bench board length matches but support pattern differs | Board can fit poorly or weaken under use. | Check underside support, board thickness, wood species/finish, and exact bench location. | Approve only after layout position is confirmed. |
| Handle/gasket profile appears close in photo | Small profile differences create leakage, rubbing, or cosmetic mismatch. | Ask for ruler photo, cross-section/profile photo, old part location, and quantity. | Dealer can approve if profile and location are clear. |
Compatibility record fields for reusable dealer files
| Field | Example entry | Why it should be saved | Reuse condition |
|---|---|---|---|
| Model and version | CSA-214 indoor room, 2026 order, controller V2. | Prevents future orders from using a visual match only. | Reuse only for same model, version, and voltage. |
| Approved part family | Controller set: display, sensor, connector, manual note. | Clarifies whether the part is single item or kit. | Reuse if the full kit scope matches. |
| Evidence set | Old label, new label, connector, location photo, order record. | Shows why approval was made. | Reuse only when evidence pattern repeats. |
| Approver and date | Factory technical review, dealer parts manager, date. | Keeps responsibility clear if issue repeats. | Review again after product version changes. |
How to use these examples
- Compatibility evidence should be stored as a reusable file, not lost inside a chat thread.
- If a part is safety-critical, the dealer should not approve it from visual similarity alone.
- A rejected compatibility case should still be saved so the same wrong match is not repeated.
Editable case-pack note: Dealer teams, service teams, distributors, and facility managers can ask CSauna for this example table in spreadsheet form. It is intended for buyer-file setup, service training, warranty review, and spare-parts control; it does not need to be framed as a quotation request.
