There was probably a kind od generic Safari manual, but the bulk of it would have been separate manuals for the individual appliances and systems. Most of those will be available online. List all your appliances, e.g. a/cs, water heater, fridge, furnace, tvs, water pump, etc. and then Google each one coupled with "manual" and you will find most.
Here is one good place to start:
