HI, I am involved in a site that has a Pqry 407c,unit connected to 8 indoors. Its been giving problems for a while. Basically about half of the units seem to work perfectly most of the time while the other half work for maybe 20 mins after doing a virgin re-start and the gradually the air off temp rises and rises. There is no leak on the system as i have carried out a pressure test. The unit never shows a fault but the compressor does not seem to ramp up, even though some of the indoors are well over their setpoint.
Could there be something wrong that the compressor is not ramping up?
I have checked all the addresses, b,c box etc and cant find anything wrong. Even if i turn off the 4 "good" units the cooling out of the other 4 is not good at all. Im 90% its not SOG but could be wrong
Any help will be greatly appreciated as im starting to look stupid in front of the client!
Thanks
