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.

6) A liquid charge is recommended 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) Close the high-side valve on the gauge manifold, then close the refrigerant access valve 

(if applicable). Disconnect the gauge manifold hose.

9) Cap the access valve to prevent a possible leak.

When replacing a component listed below, see the notes to help ensure proper 
operation.

Compressor

Install a new drier and PTC relay.

Upper and Lower 
Bearings

Inspect the upper bearing for wear. See "V.C.1. Upper Bearing Wear Check." Replace 
if necessary. When replacing the upper bearing it is advised to also change the lower 
bearing at the same time.

Evaporator

• Install a new drier.
• Inspect the mechanical seal and O-ring prior to installing the new evaporator. If worn, 

cracked, or scratched, the mechanical seal should also be replaced.
