Hi guys,

Im looking for an east way to pump down this system, i dont want to recover it due to access so looking to be able to active the force pump down mode..

Unfortunately the is no manual on site and nothing obvious on the unit.

Any help appreciated.

east way?-run it in heating to get the room temp up then change to full cooling and shut the liq line and when ur suction gauge goes into a vac then shut the suction valve.-not recommended on long piperuns,also valves can pass so they will req capping with copper caps .
