8 – Maintenance and Repair
Replace the gas filter element
1. Turn OFF the power, disconnect the power cord, and make sure the gas supply is disconnected.
2. Position the rear of the power supply so the removable gas filter bowl is easily accessible.
3. Grasp the filter bowl with your right hand.
4. Push down the thumb latch and turn the filter bowl approximately 45 degrees to the right.
5. Pull the filter bowl straight down to remove. You can see the white filter element and retaining nut.
6. Unscrew the plastic retaining nut that secures the filter element.
7. Replace the dirty element with a new element. Reinstall the plastic retaining nut to finger-tight only.
8. Clean the filter bowl by removing any oil or other residue.
9. Inspect the o-ring at the top of the filter bowl. If necessary, replace the o-ring with the one provided in the kit. Apply a
thin film of silicone lubricant to the o-ring before installing.
10. Insert the filter bowl with the thumb latch positioned approximately 45 degrees to the right of center. This is the same
orientation in which the filter bowl was pulled down and removed.
11 . Vertically align the filter bowl (with metal guard) and firmly push the filter bowl up to the top of the receptacle to seat
the bowl. It is helpful to lift the bowl with your left index finger under the nut on the bottom of the bowl.
12. Once the bowl is seated properly, turn the bowl 45 degrees to the left until you hear the thumb latch click into place.
13. Reconnect the gas supply hose to the power supply and check for leaks.
14. Reconnect the electrical power, and turn ON the power switch.
