You'll need to hook up a relay to your remote turn on lead to power the pump.
The best way to fill the system is to use the pump to draw the liquid into the system through the open end, and then put the hose in place once the system is filled.
If all this sounds foriegn to you, don't do it. The C.H.I.L. system is one of those things that really needs a little experience, or the quick wit of a good installer...
