Flushing/Descaling Procedures
1. Followand understand allsafetyrelated information providedwiththe tankless
water heater as well as the ushing system before starting the ushing
operation. Wear appropriate safety apparel including safety glasses and
rubber gloves. Inspect all hoses and electrical cords for any kinks, cuts,
etc. that could result in an electrical shock hazard or uid leakage. Replace
any worn or damaged components. Consult appliance instruction manual
for complete ushing instructions.
2. Disconnect power to the tankless water heater, following the instructions
provided with the appliance.
3. Drain the water heater following the instructions provided with the appliance.
4. Close the Cold Water Supply Valve and Water Heater Outlet Valve, isolating
the heat exchanger.
5. Connect a hose (supplied with the system) from the tting labeled “Pump
Discharge” on top of the Flushing System to the Service Valve on the Cold
Water Supply side of the water heater.
6. Connect a hose (supplied with the system) from the tting labeled “Return” on
top of the Flushing System to the Service Valve on the Hot Water outlet side
of the water heater.
7. Remove the black threaded cap on top of the system and add no more than 2
gallons of virgin food grade white vinegar to the tank. Replace the threaded
cap. Make sure the included o-ring is properly seated in the cap to provide a
leak proof seal.
8. Open the Hot and Cold Service Valves to the water heater heat exchanger.
9. Plug Power Cord from the Flushing System Pump to a properly grounded
electrical receptacle. Never allow the pump to run without adequate liquid
in the tank or possible damage to the pump may occur.
10. Allow the pump to circulate the vinegar solution for at least 45 minutes
or per the appliance manufacturer’s recommendation (consult appliance
instruction manual). Monitor the system for leaks or any peculiar behavior.
Unplug the power cord if the pump stops, an external leak develops, or the
ow is greatly reduced.
11. After the required time expires, unplug the power cord from the receptacle.
12. Close the Service Valve on the Cold Water Supply line and disconnect the
hose end from the Service Valve.
13. Disconnect the hose end from the Flushing System “Return” Line Connection
and route it to a suitable drain or to a bucket. Connect an extra length of hose
if necessary.
14. Open the Cold Water Supply Valve to ush the water heater with fresh water,
rinsing out the cleaning solution. Let the system ush for 5 minutes or as
required per the appliance instructions. Monitor the discharge from the
hose. If using a bucket, empty as needed.
15. After the required time expires, close the Hot Water Service Valve and disconnect
the hose.
16. Open the Hot Water Supply Valve.
17. Restore power to the heater system and return it to service.
Afer completing the flushing operation:
1. Discard the contents of the Flushing System by removing the threaded cap
from one of the tank access connections on the top or side of the tank. Pour
the contents into a suitable drain.
2. Remove the Return tting from the top of the tank to access the strainer
assembly. The strainer element is connected to the tting with a hose clamp.
Loosen the clamp to remove the strainer. Discard the contents of the strainer
and rinse away any remaining particles. Inspect the strainer for any tears or
damage. Replace the strainer as needed. Order P/N 150786. Re-assemble
the strainer to the tting assembly and tighten clamp.
3. Replace the tting assembly into the cover of the tank.
4. Add approximately one gallon of fresh water to the tank. Connect a hose to the
Pump Discharge connection and route to a suitable drain. Plug in the pump
to ush the vinegar solution out of the pump. Pour any remaining liquid from
the tank and replace threaded caps.
5. Store the pump system in an appropriate location to prevent damage by impact
and temperature extremes.
