3.6Filling the Pumped Circuit—R-134a

Using a refrigerant pump or cylinder heater pads will speed the charging process.

1.Connect a charging manifold to the service port of the receiver outlet valve or to the suction and discharge side of the pump.

2.Purge the hoses.

3.Calculate the amount of R-134a refrigerant needed to charge the system, using the values in Tables 6, 7, 8 and 9; for assistance, refer to 3.6.1 - Calculating Refrigerant Charge— Example. The section includes a worksheet to calculate system refrigerant charge requirements.

4.Weigh in the calculated charge.

5.After adding the calculated charge, allow the system to sit 15 to 30 minutes to reach equilibrium. Observe the refrigerant level through the sight glasses of the receiver. The level should be above the second sight glass at a minimum when the Liebert XDP is off.

6.If the refrigerant level is improper, the charge must be adjusted.

If the level is too high or too low, recalculate the required charge and reduce or increase the amount as needed to reach the proper level.

NOTE

All lengths in Tables 6, 7 and 8 are actual pipe lengths, not equivalent pipe lengths.

NOTE

System refrigerant volume calculations derived from Tables 6, 7, 8 and 9 are based on a fully loaded system. Additional charge may be required for lightly loaded systems.
