SCOPE
When performing service work on a CEV Post-Mix dispensing unit that involves opening the refrigeration circuit to the atmosphere, replacement of the liquid line drier is necessary .
ACTION Drier Replacement Instructions
1. After recovering refrigerant charge from system, remove factory OEM drier by sweating brazed joint s apart. Leave service line taps or valves open to atmosphere while sweating joints to prevent explosions!
2. After removing factory OEM drier , clean outside of cap tube and .250" condenser liquid line. Be sure inner diameters of cap tube and .250" liquid line are free of debris, solder or blockage.
3. Place cap tube and .250" condenser liquid line into the Service Replacement Drier . Place a heat sink source around Service Replacement Drier before brazing joints.
4. After Drier has been installed connect vacuum pump and micron gauge to system. Pull the refrigeration system to a 250 micron vacuum. After the system has reached the desired vacuum, let vacuum pump run for an additional 30min. A standing vacuum test may be preformed at this time as a pleliminary means of leak checking. Monitor the system for a pressure rise, if rise occurs that is an indication of a vacuum leak or moisture in the system. If a leak is suspected, locate leak, repair leak and repeat step 4.
5. When system has been pulled into a vacuum and no leaks are present charge the system by weighing in the correct nameplate refrigerant charge.
