There is no risk to damage the module even if you short the resistor(unless
you connect it to mains voltage or similar :-)

I'd recommend a value in the range 10k (~ doubles the max. level) to 2k2 (~
max. level x10).

Good luck

btw: it's not necessary to remove the existing 22k resistor. Simply connect
the new resistor in parallel to the 22k type on the bottom of the pcb.
