Non-condensables would _ the pressure on the high side of an active recovery device.

Explanation:
Non-condensables in the condenser hinder heat rejection. They take up space and add an insulating barrier, so the refrigerant can’t condense as easily. To push the vapor through and achieve condensation, the compressor has to develop a higher discharge pressure. That means the pressure on the high side of an active recovery device increases when non-condensables are present. Purging air or evacuating and recharging properly helps keep that high-side pressure down.
