Solenoid Valve Replacement for 1030/1031 Compressor

*WARNING: Unplug compressor before beginning. Before replacing valve, draw all

of the air out of the compressor by pressing both the + and – buttons on the exercise
equipment. When this is done, shut off valve to exercise equipment by turning the red
handle clockwise. When the valve has been turned off, it should be parallel to the
compressor like this:

The Mac® valve cannot be cleaned. Therefore, once faulty, it must be replaced.
The Allenair® valve functions well in this application, and it can be cleaned.
There are three steps for valve removal:

1 Dismount valves
2 Remove hoses
3 Remove electrical wires from circuit board

Step One: Dismount valve

First, remove the screws on either side of the valve. There are two.
Use the needle nose pliers to grab and hold the nut underneath the valve while using a
Phillips screwdriver to remove the screws from the top.

Inside the computer control system box, cut all other zip ties holding the four wires.
Trace each of the wires from the valve to the circuit board. There are two per valve, four
wires total. The connectors are marked V1 and V2 on the circuit board. Remove each
connector from the circuit board by pushing down on the board as you use the needle
nose pliers to pull up on the connector. This allows you to safely remove the connectors
without flexing or breaking the circuit board.
