Installation Instructions

This Flushmate system is designed as a direct replacement for existing Flushmate 500, 501, 501-A, and 501-B series units. It is not intended for retrofitting gravity-fed toilets. Ensure the serial number of your old Flushmate tank matches the required format (e.g., XXXXXX-F31A-XXXX) and corresponds to the correct china manufacturer.

Turn Off Water Supply: Locate the water shut-off valve behind the toilet and turn it clockwise until the water supply is completely off. Flush the toilet to drain the tank.
Disconnect Water Line: Disconnect the water supply line from the bottom of the toilet tank. Have a bucket and towel ready to catch any residual water.
Remove Old Flushmate Unit:
- Remove the toilet tank from the bowl if necessary for access.
- Unscrew the tank nuts securing the Flushmate vessel to the toilet tank.
- Carefully lift and remove the old Flushmate unit from the tank.
Install New Flushmate Unit:
- Position the new Flushmate M-101526-F3BK vessel inside the toilet tank.
- Secure the vessel using the provided tank nut and lower supply nut. Ensure a snug fit to prevent leaks, but do not overtighten.
- Install the new handle replacement kit, connecting it to the Flushmate system's flush mechanism. Note that the flush handle screw often has a left-hand thread.
Reconnect Water Line: Reconnect the water supply line to the new Flushmate system's inlet.
Restore Water Supply & Test: Slowly turn on the water supply valve. Allow the tank to fill. Check for any leaks around the connections. Flush the toilet several times to ensure proper operation and adjust the cartridge if necessary for optimal flushing.

Maintenance

Cleaning: The enclosed design of the Flushmate system helps keep the inside of the toilet tank clean. If cleaning is required, turn off the water supply, drain the tank, and carefully remove the Flushmate unit. Clean the tank interior with a mild cleaner and soft brush. Avoid abrasive cleaners or harsh chemicals that could damage the Flushmate unit.
Inspection: Periodically inspect the water supply connections and the Flushmate unit for any signs of wear, damage, or leaks.
Chemicals: Do not use in-tank chemical bowl cleaners, as these can damage the Flushmate system components and void the warranty.
