Additional Cross Ref., Compatibility & Installation
Installation instructions:
Connect the BLACK W3 wire to the fuse holder mounted inside the control box and then connect the wire on the other side of the fuse holder to"J61 BLK AC" on the alternate replacement circuit board.
(No soldering needed.)
Tip: If "J61 BLK AC" is occupied then use "J62 BLK AC" instead.
Failure to move this wire to the correct location will prevent your system from running properly and may also cause damage to other equipment including this circuit board.

For systems with two jet pumps or an electric air blower set dip switch "A7" to the OFF position.
Tip: It is a good idea to make a note of this adjustment on your wiring diagram's dip switch descriptions (for future reference) .
Tip: The wiring diagram is usually located on the inside of the control box.

Set all other wires and dip switches on the replacement circuit board as per how they are on the old circuit board.
Note: If the new alternate replacement circuit board has a wire that is not on the old circuit board (or visa versa) then just ignore it.

Please note: system start up process can take up to 10 minutes.
