opened. 

2. Do not replace the drier until after all other repair or replacement has been 

made. Install the new drier with the arrow on the drier in the direction of the 
refrigerant flow.

3. 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).

1) Remove the refrigeration system cartridge. Perform steps 1 through 14 in "IV.B.1.

Recovery Procedure." Once the refrigeration cartridge is out, proceed to step 2.

Be careful when handling the cabinet evaporator assembly. This assembly 
includes a defrost heater sheathed in a glass tube. This sheathing can be 
easily damaged and may also cause cuts if broken. The defrost heater will also 
be hot after a defrost. Use gloves when handling and avoid touching the glass 
directly. Also prevent the defrost heater from touching other parts.

2) Remove the defrost heater, defrost thermostat, defrost and cabinet thermistors from the 

evaporator. See Fig. 3.

3) Remove the evaporator shroud and evaporator bracket from the evaporator.
4) Remove the insulation tubing, and disconnect the evaporator inlet and outlet tubing.
5) Remove the screws holding the evaporator to the refrigeration system cartridge. 
6) Remove the evaporator and drier.
7) Place the new evaporator and new drier in position. Provide a safe means for 

supporting the evaporator.
