Installation Procedure

 

 

Controller  shall  be  installed  inside  the  unit 
electrical  box;  mounting  holes  are  available 
on  the  location  of  the  previous  board.  The 
plastic stand-offs from the UPM board match 
the pilot holes on the electrical box.   

Remove Old Board 

1.

 

Locate  existing  UPM  in  unit  electrical 
box. 

2.

 

Verify old part number on the old board 
as one of the four listed on page 3. 

3.

 

Take  a  picture  or  LABEL  all  wires 
currently  present  and  according  to  the 
terminal  designations  on  the  UPM 
board. 

4.

 

Disconnect  all  the  previously  labeled 
wires. 

5.

 

Remove existing circuit board. 

Mounting Holes 

If existing UPM has plastic stand-offs, pinch 
the  tab  on  the  stand-off  from  the  top  side 
and  push  downward  to  release  it  from  the 
circuit board as shown in 

Figure 2

. The snap 

the new board onto the stand-offs. 

If  existing  UPM  does  NOT  have  plastic 
stand-offs, choose one of the following: 

A.

 

If drilling is possible bigger pilot holes 
will need to be made.  

1.

 

Use  a  unit  bit  or  a  3/16”  (0.187”) 
drill bit to enlarge the existing pilot 
hole of the electrical box.
