GERBER GER20918 Two Piece Toilet

Product Information

This Installation Manual is for Two Piece Toilets. The water closet has conventional fittings throughout, which makes it easy to understand and install. The tank to bowl assembly has lock nuts, tank bolts, rubber washers, plastic wing nuts, beveled gasket, and two-channel pads. The plastic trim parts of the toilet should not be exposed to strong oxidizing agents, chlorine, or acid levels of lower than 5.0 pH as some bowl/tile cleaners contain such agents. The warranty excludes such failures.

Product Usage Instructions

Before assembling the tank to the bowl, check the tightness of lock nuts on both the flush valve and fill valve.
Assemble tank bolts in the tank with rubber washers and plastic wing nuts. Tighten the wing nuts by hand sufficiently to compress rubber washers and ensure water seal.
Assemble the beveled gasket to flush valve shank so that lock nut is enclosed in recess, making sure that the entire surface of the gasket is in contact with the tank bottom.
Place two-channel pads in recesses on the back of the bowl ledge to prevent china-to-china contact.
Place tank assembly in position. Do not use putty. Plastic wing nuts are tightened by hand sufficiently to compress rubber washers and ensure water seal.
Do not use non-original parts during installation or repair as Gerber will not be responsible for the use of non-original parts.
The plastic trim parts of the toilet should not be exposed to strong oxidizing agents, chlorine or acid levels of lower than 5.0 pH as some bowl/tile cleaners contain such agents.
Do not use tank-type bowl cleaners as they can cause tank component failure and damage.
Do not use a wax ring during installation.

INSTALLATION 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.

Before assembling tank (B) to bowl (G) check the tightness of lock nuts on both the flush valve and fill valve.
Assemble tank bolts (C) in the tank with rubber washers (D) and plastic wing nuts (E). Wing nuts should be tightened by hand sufficiently to compress rubber washers and insure a water seal.
Assemble the beveled gasket (F) to flush the valve shank so that the lock nut is enclosed in recess, making sure that the entire surface of the gasket is in contact with the tank bottom.
Place two-channel pads (I) in recesses on the back of the bowl ledge to prevent china-to-china contact.
Place tank assembly in position. USE NO PUTTY. Plastic wing nuts (E) are tightened by hand sufficiently to prevent rocking; and 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).
Connect the supply line (M)(not included).
DO NOT USE PIPE DOPE OR TOOLS ON PLASTIC PARTS! HAND TIGHTENS ONLY! OVERTIGHTENING MAY SPLIT THE FILL VALVE OR DAMAGE THE BRAIDED HOSE (NOT INCLUDED) AND WILL VOID THE WARRANTY!
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.
Adjust the water level in the tank to the marked water line. Turn the water level adjustment (L) to move the float cup (K) up or down.
Check the action and nut tightness (left-hand thread) of tank lever (J). Also, check the looseness of the flapper chain (there should be slight slack in the chain when at rest) and the seal of the flush valve flapper.
Plastic bolt caps and Plastic washers (H) are provided to be used as indicated in the illustration.

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.
