Installation 1. Shut off water supply. Flush toilet; sponge remaining water from tank. Remove old ballcock. 2. Slide threaded valve-shaft through hole in bottom of tank. Note: Be sure to install valve in the locked position at the angle shown in Fig A. Thread mounting-nut onto exposed shaft under tank; hand-tighten the nut. 3. Connect water supply as shown below. Pipe dope is not recommended. Hand tighten only; do not over tighten coupling nut. 4. Finally, attach refill tube to valve and clip other end to overflow pipe. Note: For Mansfield flush valves Fig B, use special refill tube adapter, Hunter P/N 617301 or Lavelle R528 (sold separately).

Water Level Adjustment 1. To adjust, simply turn upper half of valve counter-clockwise to unlock, pull up till water line on valve is level with water line marked in tank, Fig.C then turn clockwise till valve snaps into locked position. 2. Turn on water supply to fill tank. 3. Tamper proof key is optional, and may be used to simply to prevent further adjustment once final setting is achieved. Fig D |

Helpful Hint Did you know, that if the top of the overflow pipe in your toilet is higher than the level of the flush lever opening, water could leak out? To test this important system, overfill the tank to check that overflow pipe is not too long. Top of overflow pipe should be 3/4" or more below flush lever opening for safe installation. If not, cut off overflow pipe as needed. |

Servicing Instructions A. Turn off water supply. Flush toilet. Remove refill tube and snap off cover (A) B. Remove float by gently squeezing float arms inward. (B) C. While holding valve with one hand, twist cap 1/8 turn counter-clockwise and remove. (C) D. Lift out center tube. (D) E. Use pliers to remove strainer from center tube. (E) Clean strainer and cap by rinsing under running water. F. Re-assemble valve by reversing the above procedure. Note: If the main valve is worn out, (look inside cap), cleaning will not suffice, and a Replacement Cap Assembly, Hunter P/N R528 will be required. Note: If the fill valve turns on and off by itself, or runs continuously without spilling into the overflow tube, the problem is not the valve. The fill valve is running due to a slow leak in the tank, probably caused by a flapper. Either worn out or misaligned.
