I'm trying to maintenance a MSY-17NA Mitsu Mini Split... does anyone know what the low side pressure should read for this unit?

 

[bronzbeard]

there is no specific reading

I realize that the pressure depends on a number of variables... just looking for some general pointers/advice on what readings should be acceptable or unacceptable...

im just checking to make sure the unit runs properly... if there's a leak somewhere i'll be adding r410a after i fix it
