Your best bet is to get a pro to do it for you, he will only charge you RD1000, to RD1,500, do it properly and he will be a handy person to have to call when it does something you don't understand. Usually when you buy the unit they will recommend someone. Also for warranty reasons, if you do not do something correctly and screw up then the warranty will be void, as you installed it wrong. Get a pro to do it right, if it goes wrong then the warranty will stand as he is a pro, and if he installed it wrong then he will be responsible for compensating your loss if the warranty is voided by the incorrect installation. Either way you are covering your back by having nothing to do with any faults that ocurr.
