5-2. 

ACCESS TO THE INTERIOR OF THE BLANKETROL III UNIT 

 
All internal operating components are readily accessible by removing the rear enclosure panel, 
removing the top of the unit, or extending the front storage drawer.   
 

 

NOTE:  DRAIN THE RESERVOIR AND DISCONNECT THE POWER CORD 
FROM THE POWER SOURCE BEFORE REMOVING ANY PART FROM THE 
UNIT.

 

5-2.1.  Removing the Rear Enclosure Panel 

 

 

A. 

Remove the four Phillips screws, one in each corner on the rear enclosure panel. 

 
B. 

Guide the rear enclosure panel outward and downward from the bottom so that the 
panel clears the bottom edge of the top assembly. 

 
C. 

Set the rear enclosure panel and screws to the side. 

 
D. 

Installation is reverse of removal. 

5-2.2.  Removing the Top of the Unit                               

         

                                                                  

 

A. 

Carefully pry off the caps of the two screws on the left side and right side of the unit.   

 
B. 

Remove the four Phillips screws. 

 
C. 

Carefully lift up the front edge of the top of the unit so that you can see the stainless 
steel divider reservoir cover.  The microprocessor board is attached to the top 
assembly.   

 
D. 

Ensure that no water drips on the electrical components. 

 

After the screws on the side of the unit are removed and the top is lifted, there are two ways to 
disconnect the top from the base depending upon what part is to be replaced. 

WARNING

 

 

Always 

unplug the unit 

before accessing internal components during service. 

Failure to unplug the unit could result in electric shock.

 

WARNING

 

 

Always 

unplug the unit 

before accessing internal components during service. 

Failure to unplug the unit could result in electric shock.

 

 

Working with electronic boards, plugs, and cables requires delicate handling.  
Proper 

electrostatic discharge (ESD)

 procedures should be followed during 

replacement of any electronic board.  

Failure to do so may result in damage to 

the board.
