Using oil on a new frypan

Hi! I just bought a new frypan; ‘Triply Clad Non Stick Frying Pan’. The instructions that came with it say “when using the pan for the first time wash it, dry it and apply cooking oil inside it, then heat on a low heat for 2 to 3 minutes. Leave it to cool down, wash it with a sponge, mild detergent and warm water, rinse and dry as usual.” I don’t plan on using oil on it to cook (just water) but should I still follow the instructions? Why does it say to do this? Thanks in advance submitted by /u/Zealousideal_Read902
