A kitchen ESP handover can contain a product catalog, a certificate and a cleaning instruction without making clear whether all of them describe the installed unit. That inconsistency follows the asset into purchasing, maintenance and later alterations. Useful model and maintenance records should identify the physical equipment and preserve the operating basis behind its selection.
Electrostatic precipitation uses washable collection cells, while UV-C and activated carbon introduce different replacement items. A facility needs to know which of those stages it owns, which model documents apply and which service actions were specified. More documents do not solve a mismatch between the records and the installation.
Start the asset record with the installed assembly
Record what arrived. Match the equipment identification and supplied accessories to the purchase schedule, then keep the relevant drawings with the asset record instead of treating the entire manufacturer’s catalog as the installed specification. A catalog may contain several arrangements with different capacities and functions.
Polygee’s electrostatic precipitator for kitchen directory includes LK in-duct products, LK-E engineering products, integrated hoods and separate odor modules. Electrostatic precipitation appears across those categories, but the categories are not interchangeable entries in a maintenance system.
Give each installed stage a traceable identity and location. The record should let a purchasing colleague or service contractor determine which assembly is being discussed without guessing from a photograph, particularly where similar units serve different kitchens in the same property. Retain the source document for each important specification.
Keep revisions attributable. When a contractor updates the kitchen ESP schedule, identify the installed change and the document it replaces, then make the current version available to both purchasing and maintenance. Otherwise a correctly updated drawing can coexist with an outdated parts enquiry, leaving both teams confident that they are working from the approved information.
Attach the electrical information to the correct model
Polygee identifies UL 867 File E522667 for its LK/SE-6K, LK/SE-12K and LK/SE-18K in-duct models at 230 V/50 Hz. Its published description also identifies a separate file for the power supply. These are manufacturer-stated document scopes, not a reason to assign the same certification or supply information to every catalog product.
Keep the scope attached. Electrical drawings, equipment identification and the supplied documentation should agree on the proposed or installed configuration; where they do not, ask the supplier to resolve the discrepancy before the facility treats the record as authoritative.
This matters during replacement purchasing. A familiar family name does not establish that a replacement assembly has the same supply, connections or document coverage. Use the installed model and the supplier’s approved replacement information rather than buying from a generic category entry that has lost those distinctions.
Label the boundary behind each pressure figure
The product directory gives equipment-resistance figures of 23 Pa for LK-E1, 31 Pa for LK-E0 and 34 Pa for LK-E2. Store the associated model and stated basis alongside each value. A pressure field with no indication of which components it covers invites a future user to apply it to the wrong extent of the system.
The ecology-unit guide separately describes the complete LK-E stage, including its distribution plate, at no more than 150 Pa, while the cell itself contributes approximately 20–30 Pa. It calls for configuration-specific UV and carbon resistance figures. A cell value cannot silently become a complete treatment-train value in the facility database.
Preserve the design airflow and the fan review with those entries. If an odor module is added later, the responsible engineer should be able to identify the original system basis and what has changed. This is more reliable than reconstructing the selection from isolated numbers copied into different spreadsheets.
Separate reported test results from design descriptions
Polygee reports 96.0–97.6% grease removal in third-party tests for LK units and separately describes 98.0–98.1% tested efficiency for its HME integrated hood. These results belong to different product arrangements. An asset record should not inherit the largest percentage shown on a shared product page.
Retain the applicable report. Identify its tested model, airflow, method and conditions so that a maintenance manager can distinguish the supplied evidence from a general design-efficiency label or a sales summary. The reported result is useful only when its subject remains clear.
Also distinguish laboratory evidence from site observations. A clear outlet during commissioning is a record of that operating condition, not an independent reproduction of the laboratory test. Store both accurately where available, without allowing a broad field labelled efficiency to conceal how each value was obtained.
Write maintenance records around the actual treatment stages
The supplier’s guide separates washed electrostatic cells from consumed UV-C lamps and activated carbon media. Frames remain while carbon media is exchanged. These distinctions should carry into work orders, replacement-item records and service reports rather than being compressed into an instruction to clean the unit.
A completed work order should identify what was done. Removing and washing collector cells does not prove that lamps were replaced or carbon media renewed, so a single completion tick for the whole assembly can give the next contractor a false picture of its condition.
Record the supplier’s service basis and any later revision. Cooking duty, operating hours and airflow matter to maintenance planning, while a change in menu can make an inherited schedule inappropriate. Preserve who approved the revised basis and which installed stages it applies to so future staff can follow the decision.
Keep the service route and observed condition with the asset
Documents should help someone do the work. Retain a drawing or clear record of the access side, removal route and cleaning location, especially when the installation is above a ceiling or in a crowded plant room that the purchasing team rarely visits.
Polygee’s ecology guide gives 1,000 mm of access-side clearance for its UV and carbon modules. That is a module-specific provision worth preserving in the facility record. It should not be mistaken for the casing dimension or extended to every collector without the selected equipment’s own service information.
Add observations with their context. If the visible cooking plume or odor returns, record the affected location, cooking activity and maintenance status alongside the service request, rather than overwriting the original commissioning observation. The history then helps distinguish a changed duty from a missed service action or an unresolved installation issue.
Preserve the scope of safety documentation
UL Solutions explains that UL 8782 concerns safety aspects of pollution-control assemblies installed in commercial grease ducts and does not measure grease-removal effectiveness. A document record should therefore identify what a listing covers rather than use a general certification field as proof of treatment performance.
Store the exact identifier and applicable equipment. The designer or responsible authority still needs to assess whether the proposed installation meets the project’s requirements, and a component file should not be promoted into an assembly listing merely because both documents mention electrical equipment.
No database entry can repair a missing approval. Where the supplied scope is unclear, keep the issue visible until the appropriate project participant resolves it. An orderly set of files is useful evidence management, but it is not evidence that an unchecked configuration is suitable.
Make updates follow changes in the physical installation
A handover becomes stale when replacement parts, added stages or revised operating duties are recorded only in correspondence. Assign responsibility for updating the asset information after those changes, so the next purchase and the next service visit begin from the same description.
- Confirm the installed model, location and supplied stages.
- Keep electrical information and document scope tied to that model.
- Label pressure values by airflow and included components.
- Retain separate evidence for performance tests and site observations.
- Log washed cells, UV-C work and activated carbon replacement distinctly.
A useful kitchen ESP record is consistent with the physical asset and the basis on which it operates. Model identity, pressure boundaries and stage-specific maintenance make the handover practical. They allow purchasing and facilities teams to work from shared facts without extending the scope of a catalog, certificate or old service note beyond what it actually covers.
