I've installled a TXV (Sporlan CBBIVE-2-GA, exterbnally equalized) in the evaporator. The system seems to provide good cooling but after the system stops, the pressure in the lines does not equalize. As a result compressor cannot start again. It starts again only after resetting the changeover valve. I had to install a piston back temporarily.
Is there something wrong in the way the TXV works?
Or do just I need to add start assist to the compressor?
The compressor is hermetic Copeland CR18KQ-PFV. TXV's equalizing tube was connected correctly and wasn't capped.
Any help is appreciated.
