IFO Cascade (3180/3190) Toilet/Tank
DISASSEMBLY INSTRUCTIONS
All of the trim can be replaced without removing the tank, with the exceptions of the Flush Valve Assembly
(#IFO4), the Flush Valve Gasket (#IFO6), and Water Divider (#IFO5). If the flush valve body assembly
gasket or water divider must be replaced, then the following procedure should be used for disassembly of
the tank. NOTE: When disassembly of the tank from the bowl is required, all three expansion plugs (#IFO8)
must be replaced.
1. Shut off the water and read the assembly instructions.
a. Close the water supply valve and disconnetc the water supply line from the ballcock shank.
Hold UP the lift knob to flush the toilet and empty the tank.
2. Remove the tank lid.
a. Lift the knob, hold the lift sleeve and unscrew the knob from the lift sleeve. You may insert a
thin rod or nail into the hole of the side of the lift sleeve to aid in loosening the knob.
b. Unscrew and remove the lid retaining nut from the tank lid hold-down bracket. Remove the lid
and carefully set it somewhere safe.
3. Remove the bracket assembly and float.
a. Slide hold-down bracket away from the flanges on the tank.
b. Pull the refill tube off of the metal clip on the flush valve.

4. Remove the tank.
a. Sponge out any remaining water from inside the tank.
b. Use a screwdriver, 5/16” socket, or 8mm socket and completely remove the three tank bolts

from the bowl - these must be replaced with new expansion plugs due to distortion and
breakage.
