Page 17: Maintenance
Volume Booster Relays YT-300 / 305 / 310 / 315 / 320 / 325 series Product Manual Maintenance Replacement of Parts (Repair kit) The volume booster requires regular maintenance. In particular, periodic inspection is required as the diaphragm is not permanent even when used in the operating ambient temperature range. Even if there is no problem in the operation of the volume booster, disassemble it once every 2 to 3 years to check the condition of the diaphragm and replace it if necessary. - Page 18 Product Manual Manufacturer: Rotork YTC Limited Address: 81, Hwanggeum-ro, 89 Beon-gil, Yangchon-eup, Gimpo-si, Gyeonggi-do, South Korea Postal code: 10048 Tel: +82-31-986-8545 Fax: +82-70-4170-4927 Email: ytc.sales@rotork.com Homepage : http://www.ytc.co.kr Issued : 2025-02-18 Copyright © Rotork YTC Limited.
