REPAIRING LEAKS IN STEAM JACKETED KETTLE FITTINGS
If unit will not hold a vacuum the most likely cause is a leak at one of the fittings.
Often, the easiest way to eliminate a leak is reseal the suspect areas.
1. Water Level Probe Remove, clean threads, apply teflon thread sealant and reinstall.
2. Pressure Relief Valve A / Inspect for signs of leaks. Replace if required.
B / Remove, clean threads, apply teflon thread sealant and reinstall.
3. Pressure Gauge A / Inspect face of gauge. If it contains moisture on the inside of face
replace.
B / Inspect compression nut and inspect for tightness. If it looks cracked
or damaged replace.
