Measure the superheat at the compressor suction line at least 6 inches (152 mm) away from the com-
pressor. Compare suction pressure and temperature reading between the dap4 and the manifolds. If
the difference between the manifold reading and dap4 reading is more than 5%, check for the EEV wir-
ing and any possible alarms on dap4, or EEV driver. Measure sub-cooling at the liquid line.
When charging is complete, add the correct amount of oil, if the line run exceeds longer than 20m or
66ft. This procedure must be conducted with the system running at high load (compressor at full speed).
ALWAYS use original Danfoss POE oil 160SZ from new cans.
Oil addition is calculated based on refrigerant charge, shown in the table below:
Additional Oil Required (oz)
Note: Additional oil is only needed if pipe run is longer than 20m or 66ft.
