    • The return of instruments to NortekUSA for service or repair has several formal steps:
    • Please note that there is a minimum charge for any instrument return. This charge should be paid in the web store or we will need a formal order from your purchasing department.
    • As soon as the order process is initiated, we will issue an RMA number (Return merchandise authorization) that should be written into all the relevant shipping documents. Unauthorized returns may be refused.
    • When preparing the instrument for return, please make sure you follow these instructions:
      1. Care should be taken to remove marine growth, anti-fouling paints or toxins. Instruments that have obvious marine growth or are covered with unidentified substances may be refused.
      2. Please remove all batteries before shipment. Be especially careful to remove lithium or lithium-ion batteries since they are considered dangerous goods. If batteries are included, you will not get them back after repair or service.
      3. Note that freight insurance for inbound transport is not covered by Nortek so please make sure the shipment is insured (see below for more information).
    • When we receive your instrument, we will inspect it and send you a status notification within five working days. If the service to be done only includes standard maintenance (inspection and testing of all for sensors basic functionality, cleaning O-ring grooves and changing O-rings), there will be no additional charge beyond the initial fee. If a repair is required, we will send you a quotation within ten working days after we received the instrument.
    • For systems that require repair, you have a maximum of six weeks to issue a purchase order after you have received our quotation. If we don't hear from you during this period, the instrument will be returned to your address with UPS ground service.
