How to Use:

Pour Your Treatment Chemical Into A Bucket

Fill a small bucket with the boiler treatment chemical you are going to inject into the boiler.

Fill Hydro Booster with Boiler Treatment

Make sure the Hydro Booster plunger is all the way forward in the Hydro Booster. If it isn’t, operate your drill in FORWARD to move the plunger all the way forward until you hear a clicking sound. This sound will let you know the plunger can go no further and is ready to fill. Use the included 5/16″ hex socket bit to connect the Hydro Booster to your cordless drill. 

Pull Boiler Treatment Into The Hydro Booster

With your drill set to REVERSE, place the Hydro Booster’s hose into your bucket of boiler treatment chemical. Run your drill in reverse to fill the Hydro Booster with your boiler treatment chemical. On high speed, this should take about 11 seconds.

Stop Filling The Hydro Booster Before It Reaches the “STOP HERE” marker

The “STOP HERE” at the rear of the Hydro Booster is a label to let you know when the Hydro Booster has reached its maximum capacity. When the plunger reaches this label, stop the drill – DO NOT GO PAST THE MARKER. Going past this point can cause the plunger to suddenly stop, making the Hydro Booster difficult to hold.

Connect The Hydro Booster

Using the included female brass hose swivel connector, connect the Hydro Booster hose to an available hose bib on the hydronic boiler system. Once firmly connected, turn the hose bib on. This will equalize the pressure between the boiler and the Hydro Booster.

Inject The Boiler Treatment Into The Boiler

Put the drill on LOW speed and set it to FORWARD. Run your drill until the plunger injects all of your boiler treatment chemical into the boiler. On low speed, this should take about 30 seconds. When injecting 16 ounces of boiler treatment into a 2000 square foot house with a typical 5 gallon expansion tank you can expect an increase of approximately 2-3psi of hydronic system pressure.

The Plunger Will Click When Finished

When the boiler treatment has been completely injected into the hydronic system, the plunger will stop moving forward and make a clicking sound. This indicates it has injected all of its contents into the boiler.

Disconnect The Hydro Booster

Turn off the hose bib. Relieve any residual pressure from the hose and Hydro Booster by putting the drill into reverse and move the plunger back a small amount. Disconnect the hose.
