I am in the process of installing four separate Mini Splits, one in my house I'm selling in an upstairs that gets much more hot than the rest of the house.

The other three are going in our new house, 800 sq ft upstairs and downstairs and a separate office.

Before I start laying out plans for location and such, can someone have a look over on my part list and let me know if I'm missing anything or have something I don't need.

Part List
- Uniweld RHP400 400 PSI Nitrogen Regulator
- Uniweld UNF3 Nitrogen Flow Indicator with 1/4-Inch Female Flare Inlet Connection and 1/4-Inch Male Flare Outlet Connection
- Yellow Jacket 60325 Deluxe Wratchet Hand Bender (combines 60331/60342)
- NYLOG-GASKET/THREAD SEALANT
- Fieldpiece Digital Manifolds -SMAN3
- Robinair 15500 VacuMaster 5 CFM Vacuum Pump
- FJC 6014 Vacuum Pump Adapter
- Yellow Jacket 29985 PLUS II 60" Hose Set with Compact Ball Valve Ends
- R410a Refrigerant - 25 lb cylinder - New factory sealed tank
- Ductless Mini Split System charging vacuum port adapter, Converts new R410a style 5/16 SAE service ports to accept older 1/4 SAE gauge hoses.

Can anyone let me know if I'm missing anything before I make the purchase? I know I'll need to get nitrogen as well but I can get that locally.
