5. Removal and Replacement of Evaporator

IMPORTANT

Always install a new drier every time the sealed refrigeration system is 
opened. Do not replace the drier until after all other repair or replacement 
has been made.

1) Remove the front panel. Move the flush/control switch to the "FLUSH" or "DRAIN" 

position.

2) After 2 min., move the power switch to the "OFF" position, then unplug the appliance 

from the electrical outlet.

3) Recover the refrigerant and store it in an approved container.
4) Remove the top panel and top insulation panel.
5) Remove the thumbscrews attaching spout (B) to the bin, then remove spout (B). 

See Fig. 3.

6) Remove the thumbscrews attaching spout (A) and safety bracket (A) (if applicable) to 

the evaporator assembly, then remove spout (A) and safety bracket (A) (if applicable).  

7) Disconnect the water hoses.
8) Remove seal bolts securing the extruding head. Using the cutter, lift out the auger 

assembly.

9) Disconnect the inlet and outlet tubing.

10) Remove the allen head cap screws securing the evaporator to the lower housing.
11) Lift off the evaporator.
12) Inspect the mechanical seal and O-ring prior to installing the new evaporator. The 

mechanical seal consists of two parts. One moves along with the auger, and the other 
is fixed on the lower housing. If the contact surfaces of these two parts are worn, 
cracked or scratched, the mechanical seal may cause water leaks and should be 
replaced. Instructions for removing the mechanical seal and lower housing are located 
later in this procedure.

13) Make sure the lower mechanical seal is in place, then place the evaporator in position. 

Secure the evaporator to the lower housing using the allen head cap screws.

14) Remove the drier, then place the new drier in position.

15) Braze all fittings while purging with nitrogen gas flowing at a pressure of 3 to 4 PSIG. 

16) Check for leaks using nitrogen gas (140 PSIG) and soap bubbles.
17) Evacuate the system, and charge it with refrigerant. See the nameplate for the required 

refrigerant charge.

18) Replace the removed parts in the reverse order of which they were removed. 

If applicable, make sure the safety switch components are in position.  

NOTICE! Seal bolts must be replaced once removed because seal material is 
one-time use only. Loctite 243 must be applied to seal bolt threads when seal 
bolts are replaced. Tighten seal bolts to 11.1 ft-lb/15 N·m.
