REPLACING THE RS-485 OR PUMP I/F PCB 

 
1. 

Disconnect the connector [1] from the RS-485 or Pump I/F PCB. 

 
2. 

Remove the two Phillips screws [2] from the RS-485 or Pump I/F PCB. 

 
3. 

Pull the RS-485 or Pump I/F PCB from the CPU PCB. 

 
4. 

Reverse Steps 1 through 3 to install the new RS-485 or Pump I/F PCB. 

 

 
 
NOTE:  Older units may have a 5-position cable from DC conduit.  New pump and RS-485 PCBs 
have a 4-position connector.  When installing the new PCB, make sure that pin 1 of the cable (red 
wire) matches up with pin 1 of the PCB connector.
