Evening All.

We have six PURY-EP400YJM-A's to pump down and relocate a couple of fan coils on each. Does anyone have experience or recommendations on the best procedure to pump these systems down taking into account that there are two outdoor modules.

Should I operate them in cooling for a while and then begin to close high pressure pipes on OC & OS or close high pressure pipe first OC & OS and then operate in test run cooling?

Should I use pump down mode (SW2 - 4-ON) or Cooling test run?

Should I disconnect any hot gas bypass solenoid coils?

What sort of pressure should I expect these to pump down too?

Any advice welcome

Regards
