4)Close the low-side valve and high-side valve on the gauge manifold.

5)Disconnect the gauge manifold hose from the vacuum pump and attach it to a refrigerant service cylinder. Remember to loosen the connection and purge the air from the hose. See the nameplate for the required refrigerant charge. Hoshizaki recommends only virgin refrigerant or reclaimed refrigerant which meets ARI Standard 700 (latest edition) be used.

6)A liquid charge is required when charging an R-404A system (to prevent fractionation) and optional when charging an R-134a system. Place the service cylinder on the scales; if the service cylinder is not equipped with a dip tube, invert the service cylinder, then place it on the scales. Open the high-side valve on the gauge manifold.

7)Allow the system to charge with liquid until the proper charge weight is met.

8)If necessary, add any remaining charge to the system through the low-side.

CAUTION! To prevent compressor damage, use a throttling valve or liquid dispensing device to add the remaining liquid charge through the low-side access valve with the unit running.

9)Close gauge manifold valves and disconnect the hoses.

10)Cap the access valves to prevent a possible leak.
