葡萄牙采购需求：热泵热回收通风机

I'm reaching out to inquire if you have any authorized dealers for your products in Portugal as I'm interested in purchasing them. Could you please provide me with information on whether there are any local representatives I can get in touch with? Additionally, I'd like to know if you have any installation documentation available for the product I'm interested in. Having detailed instructions would be really helpful for a smooth installation process. Thanks!
