Gerber Two-Piece Dual Flush Toilet Installation Manual

Instructions for Tank to Bowl Assembly

This water closet has been designed for easy installation. Conventional fittings have been used throughout so that the working parts and operation of this assembly may be easily understood.

1. Before assembling tank (B) to bowl (G), check the tightness of lock nuts on both flush valve and fill valve.
2. Assemble tank bolts (C) in tank with rubber washers (D) and plastic wing nuts (E). Wing nuts should be tightened by hand sufficiently to compress rubber washers and ensure water seal.
3. Assemble beveled gasket (F) to flush valve shank so that the lock nut is enclosed in a recess, making sure that the entire surface of the gasket is in contact with the tank bottom.
4. Place two channel pads (I) in recesses on the back of the bowl ledge to prevent china-to-china contact.
5. Place tank assembly in position. USE NO PUTTY. Plastic wing nuts (E) are tightened by hand sufficiently to prevent rocking. Since the tank bolts are already sealed, the tank can be leveled by the relative amount that each wing nut is pulled down on the three points of contact: beveled gasket (F) and two channel pads (I).
6. Connect the supply line (M) (not included).
7. DO NOT USE PIPE DOPE OR TOOLS ON PLASTIC PARTS! HAND TIGHTEN ONLY! OVER-TIGHTENING MAY SPLIT THE FILL VALVE OR DAMAGE THE BRAIDED HOSE (NOT INCLUDED) AND WILL VOID THE WARRANTY!
8. Make sure the refill tube adaptor is attached to the top of the flush valve overflow tube. Note: Flow from the refill tube must be positioned directly into the overflow tube.
9. Adjust water level in tank to the marked water line. Turn the water level adjustment (L) to move the float cup (K) up or down.
10. Check to make sure that the large (full flush) button of the push button (J) is positioned over the full flush button on the top of the flush valve (N). The small (reduced flush) button of the push button (J) should be positioned over the reduced flush button on the top of the flush valve (N).
11. Plastic bolt caps and plastic washers (H) are provided to be used as indicated in the illustration.

Gerber will not be responsible for the use of non-original parts during installation or repair.

ATTENTION: DO NOT EXPOSE PLASTIC TRIM PARTS TO STRONG OXIDIZING AGENTS, CHLORINE, OR ACID LEVELS OF LOWER THAN 5.0 pH. SOME BOWL/TILE CLEANERS CONTAIN SUCH AGENTS. TANK TYPE BOWL CLEANERS CAN CAUSE TANK COMPONENT FAILURE AND DAMAGE. OUR WARRANTY EXCLUDES SUCH FAILURES.
