How much space should be reserved for installing an integrated purifier?

Besides the unit dimensions, reserve space for hood operation, fan connections, oil-drawer removal, module extraction, cleaning and maintenance. Mounting it flush against walls or ceilings may make the electrostatic cells and replacement parts inaccessible. Checklist: Define capacity, accuracy, materials and operating environment before requesting quotes on a uniform basis. Request specification sheets, test reports, certificates, maintenance manuals and spare-part lists. During acceptance, verify appearance, dimensions, functions, safety protection and packaging, and keep test records. Do not compare unit price alone; include customization, freight, spare parts, after-sales support and downtime risk. Keep written records of inquiries, confirmations, FAT, acceptance and warranty commitments.
