LE AK CHECK GUIDELINES
True Manufacturing recommends to leak check a unit by using a trace amount of refrigerant and charging
the system with nitrogen to 200 psi (not to exceed 220). If leak is not located by this method, then True
Manufacturing recommends that the low side be separated by the high side. Charge both sections with nitrogen
at 200 psi and see which side does not hold.
SYS TEM EVACUATION
Any time a system is open, True Manufacturing expects the drier to be changed, the system vacuumed down to
500 microns or lower and the refrigerant charged weight in.
