Hi,

I am converting a Trane chiller from R22 to R422D. I understand the Helical Rotor compressor runs on ISO68 oil. The chiller is going to be operated at -10C. Will ISO68 be ok at this temperature or should I change it to a polyolester based oil i.e. EAL Arctic 32?

Also, the chiller has an Adaptive Control unit on it. Where can I download a manual for this, including the password?

Thanks
