Diakin chiller issue

[Stretch79]

Hi guys. This is my first post so a hello and a question and the same time.

I have a new diakin chiller which has had the charge recovered due to someone else forgetting dual port manifolds. Now recovery and vac'd the unit then recharged.

The chiller is coming up with a OffEvapPressLo on the display. It's a two circuit machine circuits A and B. Circuit B was recovered first and won't start unless A is on but when taking readings circuit B would run without A being on.

I'm trying to reset but it won't have it. Am I doing something silly stupid?

Also it has an electronic expansion valve, are you able to override these for recovery of and recharging as a cool magnet won't work on it?


Thanks

Do we assume that you don't have the operating and maintenance manual for this new chiller?

[Stretch79]

Yes not to hand that's not about unfortunately

Thanks

Spoken to DAIKIN and they say there is no way to by pass the eev?

Probably has a recovery/charge mode in the software.

What model is the chiller?

Hi fault.

Thanks for trying to help. Basically being the eev and coming up low pressure on low side I put some vapour into the suction side. This equalised the pressure needed on the control panel. Fault codes gone and all up and running.

Thanks
