I'd suggest keeping it at 24/7 hashing.
Only thing to avoid except high temperature - high fan speeds. Most common issue with every gpu miner out there - is when the fan dies because of it's high usage. Not a big problem per se, but still a setback.

Keep them cool and keep them running $
I restart maybe once a month on win7 just to install updates and give it a reboot. None of my rigs have all the same model card in them as I am way to cheap to have bought them all new and at once.
Did you have any problems with used cards?
three of my 7 are new, and no I don't have problems.
Until you keep control of temperatures, there is nothing to worry.
I restart mine due to power outages, the mining software ( for the USBs is BFGMiner ) and it is restarted when I change devices ( time varies due to delivery from either group buys or eBay purchlters ases and/or issues with powering hubs ).
Alot of my mining stuff is used. The USBs worked fine ( 3 are used out of them all ) and I have a bi-monthy reflow of an old HD 4850 card that may give up one of these times due to the heat it suffers mining and how curved the board has become over time. I've had my share of bad experiences ( hd 5850 that won't do anything and does not show anywhere but complains if it's not got both 12V lines connected ) and good ones ( poor seller managed to have me as sole bidder for an erupter for a buck plus shipping ). The rules for my rig are simple due to it being in the ' outdoor smoking section '
1) keep the air filters clean, it IS outdoors.
2)keep the fans spinning, they keep it cool inside
3) Safety !!! ( refrence to Redneck Rocket Science )
4) plug holes mice can get in to, they are bad for fans and chew power cables.
5) every 3 months clean, reflow if needed and replace thermal paste on the GPUs - clean the case during the reflow time to save down time.
It's simple to use a toaster oven with timer while you are cleaning the case, the heat to 120 for 5 min, heat to 200 for 2 min and cool to 100 for 3 min before final cool does alot to keep the solder on those cards. Yes, 200 Fahrenheit. Once it's back together and mining, go to the other pc and play games, shop, etc...
results will vary with use and miners added.

As usual the answer is 'it depends'. I have r9-280x Linux rigs I can leave 24x7 but some rigs with the same os/gpu cards and just a slightly different model of motherboard I find I need to re-power (as apposed to reboot) them every 18 hours or so. So there are no hard and fast rules, just general guidelines for high availability, of which here are some:
a) Choose a motherboard with reputation for mining stability.
b) Run a linux based miner (Bamt/cgminer works for me).
c) Use a high quality power supply and don't run it close to it's limit.
d) Make sure you have failover pool configured in your miner.
e) If overclocking introduces instability dial it back down.
f) If undervolting introduces instability dial it back up.
g) Use cards of same model per rig where possible.
h) Keep everything as cool as possible (Trade this off with overclocking/undervolting based on your situation).
i) If your doing it at home, use different rings of your mains for each rig.
j) Constant power cycling, overclocking or undercooling will all reduce the working life of your rigs dramatically.

best answer... almost i can contribute though and make it best here
c)use this.These test use proper EQ not some multimeter toys. http://www.realhardtechx.com/index_archivos/Page541.htm also searchgoogle power supply review list for more.
g) i woulndt be so sure. Why u so sure?
k) if you can, move your rigs to basement/coldest broom in house and cover all windows os there is pitch blackness for max coolness.
g) Because then when something goes wrong your not playing with driver combinations for half a dozen card types to isolate the issue. When you stick to the same model problem solving gets faster as you scale. Also cgminer does not support mixed cards requiring different gpu thread count, so youend up having to run multiple cgminers on same rig.

I was wondering to keep miner functioning well is it necessary to turn off occasionally or can these rigs run constant?
dont turn off if you dont have to because temperature cycles kill everything faster not only hardware but pretty much all that exists faster than constant temperature (no cycles)

The only necessary downtime would be to clean fans, and that is variable from location to location. If you don't remove dirt/dust the efficiency will go down as the rig will run hotter typically.
its a good idea to have your system autoreboot every 12-24 hours for increased uptime
Clueless.
I've got a Windows machine mining, and it's somewhere near 100 days since it was rebooted. It's an ancient old Dell machine, so it's not even anything fancy - it had 5 years of 24/7 use as a desktop, I stuck a couple of GPUs in it, and dumped it in the corner of the server room, and now it's just sitting there mining happily. Heck, it's still running cgminer 2.something

Nonsense. Downtime to improve uptime? Windows may be less reliable than linux, but seriously it's no longer windows 95 days. Current windows is stable long term, and there's no excuse at all on linux.
Downtime will cause thermal contraction and after enough cycles you could have some traces fail requiring a reflow. Let them run 24/7 and don't push them. Slow and steady....
Correctness

Not buy used, profit from official guarantee.

Well, turning off occasionally won't help much. Just make sure you don't force it too far..
Temperature is the most important if you want it to stay healthy..
