Water Factory SQC-3 Reverse Osmosis

I purchased a home with a Water Factory SQC-3 Reverse Osmosis Drinking Water System installed under the kitchen sink.
It seems to work fine, except for a water leak once I removed one of the cartridge filters trying to figure it out.
The system uses one High flux TFC membrane, and water factory replacements #47-55706G2 (pre sediment/carbon split), #47-55710G2 (post carbon block filter), #66-4703G2 (Reverse Osmosis membrane).
There wasn’t any paperwork on how to maintain the system, can you supply me with instructions on how to preform proper maintenance?

Thanks for contacting us.
