Component Replacement Procedures - Rheem 70103 Service Instructions Manual

Component Replacement Procedures

When performing a component replacement procedure; ensure any
escaping water is caught in a container and does flow onto any electrical
components.
When draining water from tank using the tap, some water will remain in the
tank.
 If it is necessary to remove the BWU from the wall, take care to keep the
BWU standing upright to prevent water escaping from top fittings onto
electrical components.
 If replacing an element, lock the tap open, remove the wiring connector
from the water level probe and restore power. This will allow cold water
to enter the tank and cool any remaining boiling water.
Isolate power before performing any component replacement procedures
When performing any component replacement procedure, water of an
elevated temperature may be present. Ensure PPE is worn to prevent the
risk of scalding.
