Mitsubishi Heavy SRK/SRC20ZJX-S test mode / pumpdown

[lexmark42]

Hi guys,

I am seeking for information as how to enable test mode for forced cooling on a small Mitsu SRK of the latest SRK hyper inverter series.

Usually I expect to find some kind of notice about it in the service manuals, but I had little luck with both the technical manual and the data book.

I would appreciate if you have any ideas on that.

Thanks a lot,
-Dave

9) Test run

a) For a test run, it is possible to use the dip switches SW5-3 and SW5-4 on the printed circuit board in the outdoor unit.

b) Test run time is 30 minutes. Protective devices are effectively controlled.
sw 5 4 OFF Test run for cooling
sw5 4 ON Test run for heating
sw 5 3 on to initiate test mode

Thanks a lot! That's just what I was looking for.

Is there any service manual / data book I have missed?

Cheers,
