Unit Lockouts
Periodic lockouts almost always are caused by
water flow problems. The lockout (shutdown) of
the unit is a normal protective measure in the
design of the equipment. If continual lockouts
occur call a mechanic immediately and have them
check for: water flow problems, water
temperature problems. Use of the pressure and
temperature charts for the unit may be required to
properly determine the cause.
