MAINTENANCE
Remove Lime and Mineral Deposits
The amount of lime and mineral content in the water and how
often the unit is operated will dictate how often the unit needs
to be delimed.
Units used with water that contains high lime and mineral
content may require deliming on a daily basis.
Use the following procedure to remove lime and mineral
deposits.
1. Move the Power ON/OFF (I/O) toggle switch to the OFF (O)
position and allow the unit and water to cool.
2. Connect one end of a drain hose onto the sump drain with
the other end in a bucket or open site drain in a manner
according to local plumbing codes.
3. Remove drain cap from side of unit and drain all water from
heating compartment.
4. Replace the drain cap on the side of unit.
5. Close the sump drain by moving the drain handle toward
the front of the unit until it stops.
6. Add a mixture of 75% water and 25% white vinegar into the
heat tank through the sink strainer assemblies. Do not use
flavored vinegar. Allow the unit to stand with the mixture in
the reservoir for an appropriate period of time.
NOTE: The amount of lime and mineral content in the water
and how often the unit is operated will dictate how often
the unit needs to be delimed. Units used with water
that contains high lime and mineral content may require
deliming on a daily basis.
NOTE: The time required will vary depending on the solution
used and amount of deposits in reservoir.
NOTE: Product failure caused by liming or sediment buildup is
not covered under warranty.
NOTE: The delimer used should be a safe, non-toxic, non-
corrosive solution. Follow the delimer’s instructions.
7. After cleaning, drain all expended solution from the unit
through the sump drain and heating chamber drain.
8. Thoroughly flush heater through the front and rear openings
with fresh water for several minutes until discharge is clear.
9. Re-install drain cap and close sump drain.
10. Upon visual inspection, if tank is not thoroughly clean,
repeat steps 6-9.
Draining Heater For Service Protection
Use the following procedure when shutting down the unit for
long periods of time.
1. Move the Power ON/OFF (I/O) toggle switch to the OFF (O)
position.
2. Perform the entire “Cleaning” procedure in this section.
3. Turn off the electrical power supply to the heater.
4. Make sure the water has been drained from the unit as well
as the sink or holding vessel.
NOTE: Heating element chamber holds from 2-1/2 up to 4-1/2
quarts of water, depending upon model.
Resetting the Energy Cut-Off Switch (ECO)
FR Models are equipped with a manually-resettable high
temperature limit switch that prevents the water temperature
from getting dangerously high.
If the water inside the unit becomes too hot, the high
temperature limit switch will shut the unit off.
To reset the energy cut-off switch after it activates, use the
following procedure.
1. Move the Power ON/OFF (I/O) toggle switch to the OFF (O)
position.
2. Press the high temperature limit switch until it clicks. The
switch is a small red button located on the front of the unit.
• The high temperature limit switch is now reset.
NOTE: 3CS models do not have a manually reset on the high
temperature limit switch. If the unit shuts off due to high
water temperature, turn the unit off and let it cool.
NOTE: Contact an Authorized Service Agent if the high
temperature limit continues to trip.
