Safety Precautions

• Care should be taken when working on the Flushmate System. Surfaces can become wet, which may create a slip/fall hazard. Exposed tank bolts have sharp threads and may cause injury – avoid contact. Lifting the toilet tank (up to 45 Ibs./20.4 kgs) is required. If you are unable to lift the toilet tank contact Flushmate: at 1.800.533.3460

Vessel Under Pressure

• Prior to servicing the Flushmate System, first, completely CLOSE the water supply stop and then flush the toilet to release pressure from the Flushmate vessel. Failure to do so can result in injury or damage to the toilet tank and bowl.

NOTICE

• Use of petroleum-based lubricants or cleaning products containing chlorine (household bleach, drop-in blocks or tablets, disinfectants) that are applied or inserted into the toilet tank and/or Flushmate vessel will void your
• Flushmate Limited Warranty. When cleaning the exterior of the toilet, follow the manufacturer’s recommendations.
• Install according to the applicable plumbing code.
• Use cold, potable water only.

Installation

• Please follow the toilet manufacturer’s installations
• instruction for installing the fixture. Note that the toilet requires a minimum water supply line pressure. See or refer to the manufacturers’ specifications for minimum operating pressure for the fixture. Before attaching, you should always flush the water supply lines.
• After completing the installation, you are required to adjust the Cartridge Actuator (F). To adjust, make sure the water is turned on and the vessel is completely charged.
• The Actuator needs to be set at the proper clearance, 1/8″ from either the Flush Rod or push button. To make this adjustment, hold the Actuator while loosening the
• Phillips setscrew in the center of the Actuator, and rotate the Actuator up (counterclockwise) or down (clockwise) until the proper clearance is obtained. See Figure 4 for the clearance required for the flush-handle fixture. Tighten the setscrew after adjusting the Actuator.

Additional notes:

• Water supply requirement: cold water, potable water system.
• You may be required to initially flush the toilet a few times to properly charge the system.
• Should a two-piece fixture develop a leak between the tank and bowl, please refer to the fixture manufacturer’s installation instructions.

Steps for Run-On Condition:

1. Recheck the actuator adjustment described above
2. Clean the Shank Inlet Screen ©(A) and check your water supply pressure – See Step 6
3. Remove/Rinse/Reinstall the Flush Cartridge ® – See Step 2 for Cartridge Removal/Installation.

Operation

All pressure-assist toilets get their energy from the water supply line. It is important to have sufficient pressure on the supply. Refer to the toilet manufacturers’ specifications for minimum operating pressure for the fixture.

Step 1. Check Flush Cartridge

• A. Turn off the water supply and flush the toilet.
• B. Pour water onto the top of the cartridge (Fig. 1) and turn on the water.
• C. Watch for air bubbles. A consistent flow of bubbles indicates the cartridge needs to be replaced. If no bubbles are visible, move on to Step 4.

Step 2. Flush Cartridge Installation

• A. Turn off the water and flush the toilet.
• B. Use the handle end of the pliers (Fig. 2) to unscrew the cartridge from the vessel.
• C. Drop in a new cartridge and screw in until one female thread (Fig. 3) of a vessel is showing.
• D. Turn on the water. Continue to screw in the cartridge slowly, in 1/8 to 1/4 turn increments until water stops running into the bowl and the tank pressurizes.

Step 3. Actuator (F) Adjustment

• A. Start by loosening the set screw in the center of the actuator. Adjust the height of the actuator by screwing it up or down.
• There should be a gap (Fig. 4) (about the thickness of a penny) between the rod and actuator when gently lifting the rod. When accomplished tighten the setscrew in the center of the actuator.

Step 4. Check Air Inducer (D)

• A. Place several drops of water over a hole on top of the air inducer and flush the toilet (Fig. 5). If a drop is vacuumed in, move on to step 6. If not, the air inducer needs to be cleaned.

Step 5. Clean Air Inducer (D)

• A. Turn off the water and flush the toilet. Unscrew the cap of the air inducer (the smaller of the two caps) (Fig. 6).
• Pull the duckbill out from the cap and clean it by gently squeezing it (Fig. 7) between your fingers under a flow of water.
• Inspect the lips of the duckbill. If they are deformed, the duckbill needs to be replaced.
• Reassemble, insert the duckbill into the housing (Fig. 8) body, and reinstall the cap finger tight.

Step 6. Clean Inlet Screen (A)

• A. Clean the inlet screen by turning off the water supply, disconnecting the water supply line from the supply shank, and removing the screen with a paper clip (Fig. 9).
• B. Clean the screen (Fig. 10) and replace it.

Other Points to Remember

1. Pressure-assist toilets get their energy from the water supply.
2. Refer to the toilet manufacturers’ specifications for minimum operating pressure for the fixture.
3. A blocked bowl or drain will affect the fixture’s performance. To check for this, pour 2 to 3 gallons of water into the bowl. If the bowl accumulates water in it, this would indicate that something is blocking the bowl/drain. If you need additional help, please contact the manufacturer of the flushing system, or do a word search on “pressure-assist toilets” on the web.
