i guess that the compressor (that fills up) is not running and that the oil is comming back from the suction line header is that possible?

I am very impress, very good compressor, so far, as I know, one IGV was replaced on a 90 ton compressor......the bad side of the compressor is the procedure for oil replacement....

disconect the LLS and keep the suction pressure low by starting the compressor manually....check for frost after the valve

hahaha:D and i know exactly where...;)

Y894 Receiver Pressurization Valve
Description
The Y894 is a differential pressure regulating valve used on surge
receiver type systems. It is installed in a line from the discharge of
the system...

huh??

open

??? think? why?

what changed in this system ?? the room temperature very high load

you need to install a cpr on the suction line not to overload the unit.....im surprise that the compr. doenst trip on overload!!

can u explain ?

be sure you have a minimum of 20 psig Oil differential check valve on the oil receiver,
check oils trainers, filters etc

i prefer copeland too

NO

the water-cooled cylinder heads are an option . now, do the old heads will fit in dunno

the replacement is a 4V6.2

how about 4 hrs per head

6 X 4hrs= 24 hrs (12 pistons)
8 X 4hrs= 32 hrs (16 pistons)

leave the epr on the med.temp circuit adjust it at about 55 psig then adjust the desire set point on the thermostat.

adjust lpc cut in at 20 psig cut out at 5 psig

one thing i always used is............

This is the time delay after which the control will attempt to restart the XDC after a loss of power. It
is programmable from 0.1 to 9.9 minutes in 6-second (0.1 minute) increments. The user can...

the pump do cavitate a couple time after a long shut down
ive seen it once
i presumed it was because r134 contained to much vapor(flash) before being subcooled mechanically from the r407 unit........

more refrigerant volume
more flow
more oil movement
more oil return

call a pro

lots of sense

TXV capacity =
TXV rating x CF liquid temperature x CF pressure drop


CF= Correction Factor

and i have a cool job too :rolleyes:

you probably broke the wire harness or sumting !!!!
p545 sensor harness are fragile......

carlyle use them

its bad when u get interruped

ok when its 70° outside?? 50°?? 0°??
at what level would you want to feel the temperature difference??

bring them

all you need,is a check valve on the discharge line after the oil separator.....;)

its easier with the enviroguard III

I think its bob......:rolleyes:

how many defrost a day??

The winter refrigerant charge must be either calculated or the winter charge must be topped off during low ambient conditions.
Typically, the system can be charged to a clear sight glass under...

8 out of 10 screw snap........

say thanks to many others:cool: not only carrier

anyone really using nitrogen on a rack??:confused:

3 days????:eek:




one's enuff:)

before checking circuit force a defrost to raise press. in evap.
