Wiring a Goodman packaged heat pump

Hello i am new here and would appreciate some help. i recently purchased a Goodman GPH1336H41 a package unit with a heat pump. my question is on the wiring for the electrical. my heat pump has a 50 amp and a 25 amp breaker in it. i am going to have an electrician hook it up but to save some money im going to run the lines and get the equipment for him. it appears to me it will need 2 220 circuits. my question is do i need 2 disconnects for this or is there a disconnect that will work for 2 circuits? and do i bring it off of a 50 amp and a 25 amp breaker off of my main panel? any information is appreciated. thanks

The voltage is nominal at 240 volts, but who's counting Yes, two separate circuits and two separate disconnects. You can use pull disconnects rather than breakers if you wish. The Overcurrent Protection will be the breakers in your panel. Be sure to provide water tight whips for the installer/electrician from the disconnects to the unit.

Follow the mfg. Recommendation a fused disconnect in site of the unit,but your breakers will serve that requirement,so just a pull out type disconnect will work there,follow their spec's for wire size.

Total Unit Amps - 20.06A
Min. Circuit Ampacity - 24.1A
Max. Overcurrent Protection - 40A

I'd use #10 for the heat pump section on a 2P30A breaker.

Wire size for heat section based on heater kit provided.
Heater kits
HKR-05*, HKR-05C*.... 25/min ckt A,,, 25/max OCP
HKR-08*, HKR-08C*.... 36/min ckt A,,, 40/max OCP
HKR-10*, HKR-10C*.... 49/min ckt A,,, 50/max OCP
HKP-15C*....,............. 49/min ckt A,,, 50/max OCP

depending on the run you might need a 30 amp and a 60 amp breaker at the main. and the correct wire size to handle it.
