REFRIGERANT Open DISCHARGE valve on CR CONTAINING UNIT TO BE unit. SERVICED Rotate the center valve to the “RESERVICE PORT COVERY” position. RECOVERY TANK Turn power switch to “ON” position. SCALE Once unit has started, open the SUCTION valve on the CR unit to start the refrigerant flow.
ROUTINE MAINTENANCE FILTER MAINTENANCE - the CR SERIES is equipped with a 100 mesh screen filter. This filter should be checked periodically. A partially clogged filter will slow down the recovery rate of this unit. Replace the filter cartridge as follows: 1. Use a 7/8” socket or boxed end wrench to loosen the suction port as shown in Figure 1. 2. Once loose, remove the suction port- filter cartridge assembly is shown in Figure 2. 3. Either clean the current cartridge or replace with new cartridge. (Item NO.
TROUBLE SHOOTING CHART PROBLEM: The unit will only pull down to 0 pressure or a slight vacuum. SOLUTION: Remove refrigerant hose from Suction port. Place a cap on this port: 1. If the unit pulls a vacuum, then the low side leak is somewhere between the refrigerant hose and the equipment being recovered. 2. If the unit does not pull a vacuum, then suspect an internal low side leak on the CR unit. PROBLEM: The unit starts for a few minutes, then shuts-off. SOLUTION: The high pressure switch has activated.
