1.6.4 Leakage
Cookpot leaks are almost always due to an improperly sealed temperature probe, float switches and
drain fittings. When installed or replaced, each of these components must be sealed with Loctite
PST567 sealant or equivalent to prevent leakage. In very rare cases, a leak may develop along one
of the welded edges of the cookpot, or where the tube is welded to the cookpot. When this occurs,
the cookpot must be repaired or replaced.
If the sides or ends of the cookpot are coated with water minerals, the most likely cause is spillage
over the top of the cookpot rather than leakage.
