Hi Grizzly

Thanks for your help !

My problem is, before me, the another company to modify the wiring
on the fan contactors, and the fan turn constantly , compressors on and off situation ! !! (May be in summer, in temporary situation, but no in Winter!!)

They did not see that the pressure HP fan sensor, was defective on the first fan !!

I have to change the pressure sensor and i want to place the wirring in original conformity,
and no wirring diagram in place!

Thanks

Patrick

Does this chiller not have the wiring diagrams on the inside of the Door to the Main panel.
There are wiring diags in the manual info you have.
Good luck.

Merci Grizzly pour toutes les informations!

Aucun câblage à l'intérieur du panneau électrique! (Machine fabriquée par Spain Factory, Sabadell Barcelona)
J'ai essayé sur weeb, sans succès!

Ce manuel que vous m'envoyez, est exactement pour ma machine, avec ceci,
un bidon pour résoudre la situation, merci

Question: mon refroidisseur est équipé de ceci (Photo): Quelle est la fonction?
Réfrigérant de stockage, sous-refroidisseur, situation de basse température extérieure ???
C'est optionnel? 157401574015740

Le tube supérieur Tue est connecté au Hp,
Le tube inférieur gauche est connecté uniquement à l'échangeur à plaques d'entrée avec une vanne sélénoïde,
Le tube inférieur droit est connecté à la batterie inférieure du condenseur,

Si vous avez les informations pour cela?

Merci Grizzly !!

I had to translate the page into english.
If I remember correctly, I could be wrong?
Someone feel free to correct me if I am!
But i think that is a Oil Cooling circuit using a small part of the condenser?
Check in the manual or just follow the pipes!

Hi Patric
I have been looking at this again, it may be part of a circuit used for low ambient running.
As I said before tracing it out may clarify the useage?
The more i look at it the more i think its for low ambient operation conditions.
Good luck Grizzly

Hi Grizzly

I'm Sorry for the Translation on the last message !!

You are right, that's it !!
the system makes it possible to inject directly into the evaporator inlet
via à sélénoid valve, when the externals conditions are low.

I also noticed that York Factory, placed à small heating resistor, ont the TXV Head,
i suppose it's for to help TXV opening in cold weather.

Thank you for your help Grizzly !!
