If I'm understanding I need a double pole 15 amp breaker for the electrical panel inside the house correct ?

Correct, that model calls for a double pole 15a breaker, 208 - 230 V. The power goes into a disconnect switch located outside the house, near the condenser unit - then through a weatherproof whip to the outdoor unit. The control wire that connects the indoor unit carries power to the inside component, no further wiring to the panel is necessary. HVAC Direct carries everything you need under Accessories on the product page. If you have any further questions please feel free to give us a call! Thanks.
