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 Al

Step Two: Remove hoses After the screws have been removed, take the ½ inch open-ended wrench, and loosen the nut that connects the hose to the valve by turning it counter-clockwise, and remove the hose. Unscrew nut counter-clockwise Next, cut the hose to the plastic elbow 3/8 inch from the end of the plastic elbow using the wire cutter. cut tubing Repeat steps one and two to dismount the second valve before proceeding to step three. Step Three: Remove electrical wires First, clip the zip tie tha

Next, remove the lid to the computer control system box by unscrewing the screw on either side. remove two screws on lid Then remove the rubber grommet by using the needle nose pliers to carefully pop it out of the hole. pop out grommet 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

There are four steps to Allenair® valve installation: 1 Adjust and mount new valve 2 Install single to double splitter and electrical wires 3 Secure and tie wires and replace lid 4 Test compressor 5 Note: Keep two things in mind when you are ready to install the new valves. First, the new valve requires a different mount. Second, the electrical wiring requires the installation of a s

Step One: Adjust and mount new valve First, make sure that the valve is open. Try to turn the pet-cock on the valve counter- clockwise. If you cannot turn it further counter-clockwise, it is open. open valve counter-clockwise The new valve allows you to rotate its housing for easy mounting. Use the ½ inch open-ended wrench to loosen the nut on the top of the new valve. Loosen it just enough that you can rotate the red metal housing of the valve. turn nut counter-clockwise By adjusting the hou

Next, remove the compression nut that connects the hose to the valve. Replace it with the original compression nut, attach the hose, and tighten the compression nut finger tight. Take the ½ inch wrench and rotate the nut ½ to ¾ turn. Attach the second hose to the plastic elbow by using the needle nose pliers to push the hose all the way onto the plastic elbow. If you do not properly attach the hose, the pressure from the compressed air will force the hose off the elbow. push all the way down

Take the single to double adapter and turn it so that the two top prongs are pointing to the left hand side of the box. The bent portion with these two prongs should be over the fuse. Replace the connector with the single to double adapter in L1. single to double adapter Reconnect the connector that was removed from L1 onto either of the prongs atop the single to double adapter. Next, pull the two wires that lead to the valve on your right back to the hole in the box. This prevents crossing the

Step Three: Secure and tie wires and replace lid Make sure that all of the slack is inside the computer control system box. Use a zip tie to bind the wires and hoses on the outside of the box. Use the wire cutters to cut off the excess. zip tie all wires and hoses Next, gather the four wires inside the box, and arrange them so that the small grey LED on either side of the box is not blocked from view. Tie these wires using two or more zip ties. Cut the excess from the ties. secure wires to c

feel for air flow After the flow of air has stopped, wait thirty seconds. Slowly lower the air in the compressor to approximately 95 PSI and the compressor should start. Open the valve by turning the handle counter-clockwise to allow the air to reach the equipment. Open valve by turning counter-clockwise until the handle is directly above the valve. 10-5508 Rev A Service Department (800) 888-7009 13
