CAll was reach in freezer no cool
m)G12011
s) T12921L05
box at 33* upon arrival went through system found parameters messed up, straightened that out
checked charge did not seem correct, so I pulled it. vacuum to 400 microns reset factory charge
pressures same 22/160 for 404a too low of head press,right. sh -4* at 33*box , checked coil temp -10*
bad valves , to small of an area to check amp draw and 3" ceiling very tight area . Any thoughts.

It sounds as if it may be valves or simply a worn out compressor, but if you can't get proper access, how do you expect to fix anything? Tell the customer you have to move the box to a spot with more headroom.....like outside if necessary. A quick check with Copeland's Performance Calculator will tell you if the pump is doing what it's supposed to be doing.

This box is about 83" tall.........pretty low ceilings, huh?

[skpkey9]

Yeah very low and outside also difficult busy resturant
but thanks for the reply, thats how I called it.. Thanks again:)

Suggestion time... If operating ambient was over 85*F with 3" clearance plan on removing the evap assembly and take apart the TXV, clean with alcohol, and Q-tips.;)

[skpkey9]

ambient temp 70-75*
checked against copeland curve and pump was not even close.

sounds like a metering issue.
