5 Maintenance
CAUTION
Do not attempt to repair this water heater
yourself. Call a service person for assistance.
Always turn off the power supply to the
heater prior to servicing or draining the
heater.
NOTICE
For most of these operations, the water will
have to be drained from the heater. For all
of these operations the cord should be
disconnected and the front cover removed.
5.1 Removing the cover
Remove rubber seal which covers the Phillips
n
screw(Fig. 5 [S]), and unscrew the Phillips screw.
The cover (Fig. 5, [C]) can now be removed by
n
slightly rotate. When reassembling, work in the
opposite way being careful to insert the tongue
of the cover into the slot.
5.2 Draining the heater
If the heater has been installed with flexible hoses:
Shut off the power supply.
n
Turn the heater upside down over a sink to drain
n
the water out of it.
5.3 Inspecting the anode rod
If the heater has been installed with flexible hoses:
The purpose of the anode rod (Fig. 8, [N]) is to
protect the tank against corrosion. It is critical that
the anode rod be inspected once a year to
determine whether it requires replacement. To
access the anode rod, the heating element must
be removed (see Section 5.4 Removing the heating
element). Upon inspection, the anode rod surface
should appear smooth. If the rod surface appears
pitted, bumpy, rusty, or if the rod is missing
completely, then it must be replaced.
To access the anode rod:
Remove the heating element (see Section 5.4
n
Removing the heating element).
Original anode rod sizes
Length 4.72" Diameter 0.787"
l
Certain installations may require more frequent
replacement of the anode rod:
recirculation applications
l
poor water quality
l
galvanic/electrolytic corrosion
l
high flow applications
l
In the event of poor water quality, we recommends
consulting a local water treatment professional for
water treatment options. Always ensure the water
heater is grounded. Damage resulting from poor
water quality or failure to replace the anode rod is
not covered under the manufacturer's warranty.
For additional questions, please call Fogatti
