Adding Refrigerant - Bosch Climate 5000 Series Installation Instructions Manual

Installation Instructions

9.3 Adding Refrigerant

CAUTION: CONTAINS REFRIGERANT

Refrigerant charging must be performed after wiring,
vacuuming, and the leak testing.

DO NOT exceed the maximum allowable quantity of
refrigerant or overcharge the system. Doing so can damage
the unit or impact its functionality.

DO NOT exceed the maximum allowable refrigerant length.
Refer to table 4.

Charging with unsuitable substances may cause explosions
or accidents. Ensure that the appropriate refrigerant is used.

Refrigerant containers must be opened slowly. Always use
protective gear when charging the system.

DO NOT mix refrigerants types.
Depending on the length of connective piping or the pressure of the evacuated
system, you made need to add refrigerant. Refer to table below for refrigerant
amounts to be added:

Additional Refrigerant charge per ft
Refrigerant Type: R410A
For the Indoor unit with 1/4" liquid line diameter:
(actual pipe length – standard length) 0.16oz/ft (15g/m)
For the Indoor unit with 3/8" liquid line diameter:
(actual pipe length– standard length) 0.32oz/ft (30g/m)
Actual pipe length is measured based on the refrigerant
liquid line only.
See Section 9.4 Calculation Steps to determine the
additional refrigerant amount if the Indoor units have
diff erent liquid line diameters. (Refer to table 8 for
Indoor unit liquid line diameters)
