Repairs
Remove and replace the cover and Mylar® barrier
The first step in most maintenance and repair procedures for the Powermax45 is removing the
cover and the Mylar barrier. To protect your power supply, it is important to replace both items
properly when the maintenance is complete.
Removal
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. Gently pull on the end panel nearest the screw you are removing to keep pressure on
the screw. When the screw is almost out, tilt the screwdriver slightly to help pull the screw out
of the recessed hole.
3. Tip the end panels back slightly so that you can get the edges of the handle out from
underneath them. Set the handle and screws aside. Continue to tilt the end panels outward to
release the fan side of the cover from its track. Then lift the cover off the power supply.
4. Remove the Mylar barrier from the power-board side of the power supply.
DANGER

Allwork requiring removal of the power supply cover must be
performed by a qualified technician.
