1、All products sold by our company are qualified products. When products are sold, professional installers from each exclusive store will provide on-site installation services. This avoids product damage caused by insufficient manpower or customers' unfamiliarity with the products.

2、After the installation of our company's products, professional staff will demonstrate and explain to you on-site the product usage methods, simple handling methods for abnormal phenomena, and maintenance common sense.

3、If you encounter problems during use that you cannot handle, please contact the exclusive store. The exclusive store will send professional personnel to solve the problem with you. Do not disassemble or knock the product by yourself.

4、Our company's products have a designed service life of 20 years and we provide lifelong maintenance services. The warranty period and "Three Guarantees" (guarantee of repair, replacement, and refund) period are calculated from the date of issuance of the sales receipt. Within the validity period of the product's "Three Guarantees", users can enjoy the "Three Guarantees" service with the warranty card and sales certificate.

5、If product parts become unusable due to improper use, improper handling, natural wear, or other such factors during your use, our company will be responsible for repair or replacement, but a maintenance labor fee or a fee equivalent to the value of the product parts will be charged.

6、Product damage caused by natural disasters or other force majeure events is not covered by the free warranty.

(When problems arise, please first contact the local exclusive store. If the problem cannot be resolved, please contact the company headquarters.)
