on a CVHF and all chillers there should be no work on refrigerant side meaning charging or recovering refrigerant with out flow thru all vessels with out flow you can freeze and rupture tubes

You could try factory at 1111 or 0111 this typicaly works or service tool

This is govt bldg. we have proposed that before but they said no but now they might

The problem is cured and the biggest problem was Trane's service bulletin on converting to new wiring and sensors on this Rtac was completely wrong on the wiring, I rewired by unit diagram and bound...

this is a rtac when first made and no sensors with plugs

no the led did not lite

yes I have

REPLACED HI PRES TRANSDUCER BUT BINDING VIEW DOES NOT COMM WITH AND SOUTH POLE MAGNET DOES NOT LITE LED

there is a spill point but still the best way is to test solutions and load slowly
so you can track

You may be right but remember their comm is 3 packets short from being modbus tsu, and 7 packets short from being modbus rtu

A slipper seal is like a oring going around the slide valve it works like a piston ring.

The FSU screw comp is one screw that only the manafacturerer should control because of its itricate...

yes you do energize fast unload at shut down or any operating alarm

I used to be the National Service Manager for Dunham Bush and this upgrade to the new controls will make all operations smoother and this upgrade is easy just be careful of terminal markings

Try checking subcooling should be 10 -12 f at full load and make sure that that evap water flow meets chart in machine . Water flow can change charge
and subcooling will tell you that

Try CTS Services at 1-800-791-7088 ask for Steve Wells

we need to know if you have a BMTS or BMTW, BMTX model of BCU

You can print all point info and addressing from gx-9100 guide

With out seeing the problem 1st hand we are all guessing, high water flow and condensor fouling produce the same effects the fouling can be tested with citric acid which will not hurt the metals but...

this problem is due to high water flow infringing on the metals, remember for
condensors you should have 3 GPM per ton any more will not pick up enough heat which can add to the errosion. I have...
