Chapter 6: Unit Maintenance

Never attempt to service a unit until a qualified
electrician has opened and locked out the main
disconnect using OSHA 1910.147 standards.

The water supply should be turned off and internal
pressure should be relieved before you remove panels.

All electrical connections must be done by a qualified
electrician.

Disconnect all power to the unit, let the unit
cool down, and turn off the water

prior to any

servicing

.

Failure to do so can result in SERIOUS INJURY
OR DEATH!

6-1 Preventative Maintenance

Draining

Drain the TCU thoroughly if you are taking it out of service for a long period of time, or you
expose it to freezing. Drain plugs are provided at the base of the heater tank and at the base of
the pump pedestal.

Periodic Checks

Every Six Months

Inspect all electrical connections for secure attachment and for safe and secure ground
connections. Inspect the power cable, especially at the entrance point to the unit. This
inspection should be made by a qualified electrician. Check for leaks, especially under the
pump, as it may indicate a worn pump seal.
