Operating Requirements

Water Pressure
Pressure-assist toilets harness the energy of incoming water and air to provide a more robust flush. It is important to have sufficient pressure and flow in the water supply for the Flushmate System to function.
Minimum Operating
Pressure: 20 psi / 137.9 kPa
Maximum Operating
Pressure: 80 psi / 551.6 kPa
Minimum Water Flow Rate: 1 gal. / 3.79 l in 30 seconds

Water Supply
Flushmate Systems are designed to be used with a cold, potable water supply only. Use of non-potable water supply or a hot/tempered water supply may damage the system and will void your Flushmate Limited Warranty.

Toilet Installation
This manual contains instructions to replace the Flushmate System installed in your toilet tank. Please follow the toilet manufacturer’s instructions for installing the toilet.

WARNING

To Prevent Injury:
Read Installation Manual
Read entire manual before performing any tasks.
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 lb /20,4 kg) is required. If you are unable to lift the toilet tank contact Flushmate: 1.800.533.3460

Vessel Under Pressure
Prior to servicing the Flushmate System, first completely CLOSE water supply stop and then flush 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 manufacturer’s recommendations.
Install according to applicable plumbing code.
Use cold, potable water only.

Remove Existing Flushmate


Completely CLOSE toilet’s water supply stop. Not all valves look alike. Flush toilet to release water and air pressure from the vessel. If unable to close water supply stop, contact plumber. WARNING: Failure to release pressure from the Flushmate vessel can result in injury or damage to the toilet tank and bowl.	Place bucket and towels near toilet tank to prepare for draining water from tank. Disconnect water supply line ➊ from supply shank ➋. Pliers may be needed. Drain excess water from water supply line into bucket. TIP: Verify rubber gasket remains seated inside supply line connector.

Place bucket under supply shank, completely remove supply shank locknut with pliers, and allow water to drain into bucket. Discard locknut.	CAUTION: To prevent a slip/fall hazard, use towel to wipe up excess water that may have fallen in your work area. Repeat as necessary.

Remove toilet tank lid and place flat on floor, away from work area.	Press actuator to flush toilet. This will ensure all pressure is released from the vessel. TIP: You will not hear a flush if pressure has already been released. Pull up on actuator and hold for 1 minute, until excess water from vessel drains into toilet bowl.

If you have a push button toilet, >>> Skip to Step 8. Before removing existing handle, note its orientation. To remove handle ➊, loosen and remove nut ➋ (inside toilet tank). It is reverse thread. Pliers may be needed. Disconnect the flush rod ➌ as you are removing the handle. Discard nut and handle.	Locate tank bolts and nuts under toilet tank and bowl. Some toilets have two tank bolts and nuts, others have three.

Use the flat wrench to hold upper nuts in place. Loosen and remove tank bolt nuts with 4-in-1 tool. TIP: If it is difficult to loosen nuts with 4-in-1 tool, use pliers.	Keep all tank bolt nuts and washers for re-use during installation of your new Flushmate System. Place a towel on floor of work area to protect toilet tank during removal of the existing Flushmate System.

WARNING: Lifting the toilet tank (up to 45 lbs./20.4 kgs) is required. Exposed tank bolts have sharp threads and may cause injury – avoid contact. Lift the toilet tank straight up to remove from the toilet bowl.	Lay toilet tank on towel, with the front side of the tank facing down.

CAUTION: To prevent a slip/fall hazard, use towel to wipe up excess water that may have fallen in your work area. Repeat as necessary.	Remove tank to bowl gasket from discharge extension. Discard.

CAUTION: Exposed tank bolts have sharp threads and may cause injury – avoid contact. Loosen and remove discharge locknut. Depending on your tank bolt configuration, you may need to reposition toilet tank for better access. Once removed, discard locknut.	Slide existing Flushmate out of the toilet tank. Dispose of in accordance with local waste handling procedures. TIP: Now is a good time to remove any debris you may find inside of the toilet tank. >>> You are ready to install your new Flushmate System.

Line up the Flushmate vessel with toilet tank as shown.	Release lower supply group ➊ from the vessel’s mounting post ➋. Gently wiggle lower supply group ➊ and pull to release.

Holding the lower supply group, guide the supply shank inside the toilet tank and through the small opening at the bottom of the tank.	Hold supply shank in place (inside toilet tank), and thread on supply shank locknut by hand.

Insert the new Flushmate System into toilet tank. Guide discharge extension through center opening.	Hold vessel in place so discharge extension stays centered in opening while hand tightening discharge extension locknut. Be careful not to cross-thread locknut.

Center vessel within toilet tank. Use both hands on opposite ends of the vessel to gently twist into position.	CAUTION: Exposed tank bolts have sharp threads and may cause injury – avoid contact. Tighten discharge locknut using 3-in-1 wrench, but do not over-tighten. Depending on tank bolt configuration, you may need to reposition toilet tank for better access.

Tighten supply shank locknut using 3-in-1 wrench. NOTICE: Both locknuts should be snug to prevent leakage, but do not over-tighten, as this can damage the toilet tank.
