Starting from November 2025, this automatic stop function will be activated sequentially for products manufactured in 2015. ■ Response Procedure at the Time of Automatic Stop It is anticipated that customers will contact the sales and installation stores. We ask that the sales and installation stores respond according to the following steps: 1. Conduct a safety inspection based on the "Underfloor and Attic Ventilation Fan Inspection Checklist." * Please be sure to check for looseness and retighten the connections of the controller and timer. If any liquids such as water, oil, or detergent have come into contact, the internal components may corrode, leading to ignition or fire, necessitating the replacement of the main unit. 2. If there are no issues, press and hold the set button to restart operation. ■ Start of Shipment for Controllers/Timers with Inspection Period Notification Function For details regarding the shipment history of timers, please contact our company: your sales representative or the Quality Control Department.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
