20. clean the carbon off the coil This may be done by taking it to a radiator dealer and having it boiled out The catalytic converter must be completely removed before cleaning carbon deposits or damage may result Proper maintenance of the unit such as regular tune ups proper fuel and a properly operating air pump will help prevent carbon build up on the coil and increase the life of the unit Using A212 ULTRA CLEAN INDUSTRIAL CLEANER or A217 1 ULTRAPAC RENO VATE will also greatly enhance the removal of carbon deposits Soak the coil and casing ONLY NEVER soak the catalytic converter core LEGEND SE 980059 07 23 02 4 6 MAINTENANCE VACUUM EXHAUST HEAT EXCHANGER 1 Cleaning the vacuum exhaust pre heater core is recommended as needed or if the unit was operated with the vacuum inlet filter damaged removed or improperly installed Pull out the core and remove all debris being careful not to drive debris deeper into the core We recommend removing the debris with water by either submerging the core and moving it back and forth until the debris loosens and falls off or by spraying the debris out of the core Allow the core to dry before reinstalling 2 Remove and inspect the vacuum exhaust heater core every 200 hours HIGH PRESSURE HOSES Inspect your high pressure hoses for wear after the first 100 hours of use Inspect every 25 hours thereafter hoses show any signs of damage or impending rupture replace the hos
