ClearWater MineralPURE SPA-1R, Installation & Care Manual

20

If the 

SPA-1R

 control box needs to be replaced for any reason, the 

SPA-1R

 was designed so that only the circuit board 

needs to be checked out. This allows for all external electrical connections and the enclosure to remain at the same 
location during repair. 

To remove the circuit board: 

FIRST DISCONNECT ALL POWER!!! 

1.) Open up clear lid 
2.) Unscrew four (4) screws holding faceplate assembly in place. 
3.) Lift up faceplate assembly and turn over. 
4.) Note the two sets of wires going to the circuit board. Using a small screwdriver, unscrew them. A diagram follows to 

help you reinstall a new board. 

a.) The thick black power cord has three wires coming out of it - black, white and green. A green terminal with 

three screws (next to AC Input-printed on circuit board) houses these three wires. The far left terminal, 

L2

 should 

have a black wire going to it. The middle terminal, 

L1

 should have a white wire coming from it. The right terminal,

GND

 should have a green wire coming from it (ground). 

b.) The gray electrode wire set has two wires coming out of it - black and red.  A green terminal with two screws 

(next to Electrodes printed on circuit board). 

It does not matter which wire goes to each of the terminals, just as long 

as the red is connected to one of them, and the black to the other. 

5.) Once the wires are disconnected, remove the faceplate assembly, with circuit board attached.
6.) Obtain an 

RMA

 number from 

Clearwater Enviro Tech

 before returning the faceplate assembly, with circuit board 

attached.

7.) When reinstalling the circuit board, use the following chart to reconnect. Improper connections may void the warranty. 

See warranty card for full details.
