Replace the air filter and regulator
1. Turn OFF the power, disconnect the power cord, and disconnect the gas supply.
2. Use a #2 Phillips screwdriver to remove the 2 screws from the handle on the top of the power supply. Tip the end
panels back slightly so that you can get the edges of the handle out from underneath them. Lift the cover off the
power supply.
3. Remove the gas fitting from the rear of the power supply.
4. Remove the drain hose from the hole in the bottom of the power supply’s base.
5. Disconnect the gas supply hose from the filter.
6. Unscrew the nut that holds the air filter in the bracket. Tip the bottom of the air filter away from the power supply
and slide the filter out of the bracket.
7. Position the new gas filter in the bracket and replace the retainer nut.
8. Route the drain hose through the hole in the base of the power supply.
9. Connect the gas supply hose to the new filter. If you are replacing the hose, cut the new hose to the same length
as the old hose.
10. Reconnect the gas fitting, and then reconnect the gas supply to test it for leaks.
11. Being careful not to pinch any of the wires, slide the cover back onto the power supply. Position the handle over
the holes in the top of the cover, then use the 2 screws to secure the cover.
12. Reconnect the electrical power.
