Using your new sink set is easy. First, choose the mounting type that suits your kitchen - drop - in, top mount, flush mount, or under mount. Then, use the included clips and cut - out template to install it properly. When using, place your dishes in the double bowls and let the X flume design quickly drain the water through the 90mm waste strainer. As for maintenance, wipe the sink regularly with a soft cloth to keep it clean. Avoid using abrasive cleaners as they may scratch the PVD coating. The anti - condensation paint helps prevent mould and moisture, but still, make sure the area around the sink is well - ventilated. With proper care, your sink will last for a long time.
