Depending on what your CYA level is, you can bring your FC up to shock level before you leave. For people who do not have automated chlorine injection/production systems, you can also place a floating chlorine dispenser in the pool containing a few tabs to help maintain the FC level while you are away.
I recently left on a 7 day vacation but I have a stenner pump to add the required chlorine 3 times per day to maintain my FC levels. I also run my pump from 8 AM to 8 PM every day. Since my CYA was 50, my target FC is about 6 ppm, but I brought it up to 10 ppm before I left just to be safe. I also had a family member who could check the water level and add some if it got too low. You might want to ask a neighbor to check on your pool once or twice and add water if it is needed. They could also add some chlorine for you to ensure your FC levels don't drop too low.
