7. REPLACEMENT OF MAIN COMPONENTS
7-1. REPLACING THE EVAPORATOR COIL
* Turn the unit off before replacing any part.
A. Remove all lids. Remove the dividers.
B. Cut the silicone line around the countertop frame with a knife.
Remove all screws in back of the countertop frame.
C. Remove all the screws around the lid rail.
Lift the countertop from the rear first. Push countertop forward and top will come off.
(Now, you can replace the evaporator fan motor or the temperature control (thermostat) if you
unscrew the duct(A) or the temperature control box.)

14
REPLACEMENT OF MAIN COMPONENTS
D. Carefully move the countertop to a safe place.
See the join bracket and understand join system.
E. This is the duct(A) and the temperature control box.
Unscrew the temperature control box if necessary.
F. Unplug the temperature control harness assembly.

15
REPLACEMENT OF MAIN COMPONENTS
G. Pull the sensing tube of the temperature control.
Replace the temperature control if necessary.
H. Remove the screws on duct(A) and remove.
I. Unplug the evaporator fan motor harness assembly if necessary.

16
REPLACEMENT OF MAIN COMPONENTS
J. Remove screws to the evaporator fan motor if necessary and replace it with new one.
K. Remove the screws on duct(B) and remove.
L. Remove the screws on the suction line cover (horizontal) if necessary.
