Trane air cooled water chiller help

[Psenterprise]

Hi guys, was wondering is there any remedy to rectify "m ckt1 fault"? It's for the cgah aircooled water chiller series. The instruction manual suggests resetting pressostat before resetting the SMM.

Any idea how do we do that? Pls advise.

Hi you should get aquainted with this unit, the presostats are inside the chiller, you must remove a panel to accses them, be carful!!
you should also check the compressor klixon that is wired in series with the hp presostat,
good luck:)

And be aware that generation of Trane scroll chillers (the European version at least) often has unusual HP switches. They screw directly onto the 1/4" coupling & should be a black plastic. Look for a blue dot on one side, about 6mm diameter. That's the reset button. Push it in until it clicks, then you can reset the SMM.
