Generally, we wouldn't say 'the Web' like that — it would more usually be 'the Internet', or else we would talke about a 'website'.

Saying "refer to the Web" is a bit like saying "refer to the Library" — and you simply wouldn't say that in natural EN: you would go to the Library and refer to some specific information in it (e.g. perhaps a book or directory).

I would only say 'refer to' if I was going on to say to WHAT one should refer: page 6 / a particular book, etc. But in any case, it is pretty unusual to see 'refer to' used in reference to all things Internet — though once on a website, one might find an insturction to 'refer to the 'Contacts' page for our address'

It is not in fact totally clear what you are really trying to say: do you actually mean 'please see our [specific] website'? Or do you mean 'go and look it up [soemwhere] on the Internet'?

Generally, I wouldn't use 'the web' in this way, since that strictly speaking refers to the technical infrastructure on which the Internet resides.

All credit, of course, to Port City, who was the first to suggest this in their peer comment.

Asker:
You can always use the 'discussion' area to add further information or a correction to your question.

If you were trying to say "please refer to the web [+ url]", then I'm afraid that wouldn't be at all natural in EN; to start with, we would call it either a 'website' or just a 'site', but NEVER 'the web'; but if you are giving the actual URL, then you don't really need to say anything at all: "please refer to www.mysite.com" — but I still maintain that 'see' or 'visit' is more idiomatic in the friendly and informal world of the Internet; using an unusually formal term might stand out with an unwarranted contrast compared to the style of the rest of your text.
