How can I find installation instructions for a DELTA RP21462WH

If your new Delta single handle shower valve won't shut off, it could be due to an issue with the valve itself or with the installation. Some possible causes include a misaligned handle, debris in the valve body, or a faulty cartridge. It is best to check the installation instructions and ensure that everything is properly seated and aligned. If that does not solve the issue, you may need to contact Delta customer service for further assistance or consider hiring a plumber to diagnose and fix the problem.

Email a vendor on Amazon to request specifications and installation instructions. You might want to offer to pay for a photocopy or scanned copy.

There should be a nut and washer clear up against the bottom of the counter top. I think the clip you are looking at holds the spout hose to the diverter assembly. You need to look beyond that to see the nut you are looking for. I could be mistaken, but every one of this type of faucet I have seen mounts this way including Delta. It is not easy, there is no room to work up there but it can be done. The best way is with a large basin wrench (a sort of swivel-head jaw on a rod) but with some perseverance and possibly a colorful word or two it can be done with a large pair of slip-jaw pliers too, I've done it.

You probably need to remove the spout and lubricate the o-ring seals or replace and lubricate them.

More info would be helpful.
If it is "Old" then the rubber washer/seal is probably worn in need of replacement. If new it either has a "Defect" or was installed improperly (More likely installed wrong).
SO if NEW then using the installation manual that came with it carfully remove the "Valve". (AFTER TURNING H20 OFF!). Inspect the ruber parts for damage. DELTA 800-345-3358 will replace usually (except cheapos 1or2 yrs) for life the "Defective" parts NOT WHAT YOU DAMAGED.
OLD: Go to www.delta.com look up your faucet or call DELTA and ask for the "Manual" it will give you blow by blow instructions on YOUR FAUCET how to remove/replace/repair. It is fairly simple to do. AND Delta is a VERY GOOD CO. they honor their warranties. SO DON'T ABUSE THEIR GOOD NATURE, but DO GET FREE PARTS if you deserve them. There are so few companies like that any more, lets try to keep them that way.

If you are handy, the best solution is to call delta and have them send you a new diverter. They will need the model of your faucet. The new diverter will come with instructions on the install process. As far as fixing it without the new diverter, I don't believe you will be able to.

Here is the owners manual and installation instructions for your particular faucet:
