If you choose to install the check valve, you'll need to add the auxiliary side connector to the refrigerant distributor. The reverse flow during the heating mode has to not only bypass the TEV but also the refrigerant distributor nozzle. The orifice in the nozzle is too small to allow the full mass flow of the system through it without an excessive amount of pressure drop.
The auxiliary side connector is essentially a tee, that allows you to move the nozzle from the distributor body to the ASC body, which then allows the refrigerant in reverse flow to enter between the nozzle and the distrbutor body, bypassing the nozzle.
Regarding sizing of the check valve....if it's a 5 ton system, you'll need a check valve capable of 5 tons of mass flow with a minimal pressure drop for the refrigerant in the system.
