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 the requirements of ARI Standard 700 (latest edition) be used. -
Page 28: Removal And Replacement Of Compressor
2. When brazing, protect the drier by using a wet cloth to prevent the drier from overheating. Do not allow the drier to exceed 250°F (121°C). Note: Hoshizaki recommends that compressor starting components be replaced at the same time as the compressor. Due to the ability of the POE oil in the compressor to absorb moisture quickly, the compressor must not be opened more than 15 minutes for replacement or service. - Page 29 15) Evacuate the system, then charge it with refrigerant. See the nameplate for the required refrigerant charge. 16) Connect the terminals and replace the terminal cover in its correct position. 17) Replace the control box, louver, and panels in their correct positions. 18) Plug the unit back in.
