Need to modify the floater on Zoeller

Just installed Zoeller M98 but would like to modify when it comes on and when it shuts off. The reason is that my property has high water table so there always is a little bit of water at the bottom of the pit and it hoovers about the ON / OFF level. So the pump comes on once every hour for about 5 sec....and then just shut off.... as the water level drops...but within an hour it will go back just above the ON level and it will switch on again for 5sec. When it rains - it won't be an issue as the water will be coming at a higher rate but for now I find it annoying to have the pump come on for only 5 sec every hour. I have an old type floater that you plug in and then it controls the pump power, and I am thinking of plugging in my Zoeller into that. But first would like to know if this is safe and OK and if I should disable the switch/ floater on the Zoeller or just allow the power be cut off by the use of the other, old floater. Thanks!
