What should be considered when installing a purifier outdoors?

Outdoor installations need rain, sun and freeze protection plus service access; the power and control boxes must have suitable ingress protection, and brackets should be corrosion-resistant and secure. Prevent rainwater from flowing along ducting into the cells or power box. 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.
