Fill Valve Installation 2/3 |
9. With correct WASHERS in place (see Step 8), tighten COUPLING NUT. Hand-tighten only. DO NOT OVERTIGHTEN. CAUTION: DO NOT USE CONE WASHER WITH PLASTIC SUPPLY LINE.
10. Clean drain with a soft cloth. Snap ADAPTER RING away from FLAPPER. Align FLAPPER over mounting ears located on base of OVERFLOW PIPE. Center FLAPPER over drain opening. Snap to mounting ears by pushing down on the rigid frame near mounting ears. FLAPPER should open and close without binding.
11. ADAPTER RING FOR 1" OVERFLOW PIPES WITHOUT MOUNTING EARS. If there are no mounting ears on base of OVERFLOW PIPE, install ADAPTER RING: 1) Position ADAPTER over top of OVERFLOW PIPE and press down until it expands and slips over the outside of the OVERFLOW PIPE. If the ADAPTER will not slide down OVERFLOW PIPE, remove spring, slip ADAPTER around the PIPE and replace spring; 2) Slide ADAPTER down until it contacts base of OVERFLOW PIPE. Position spring clip opposite the drain seat. NOTE: If OVERFLOW PIPE is brass, use steel wool or wet/dry sandpaper to remove excess scale from PIPE prior to installation. If OVERFLOW PIPE is larger than 1", Model 555C can be used.
12. If you have a Fluidmaster bowl cleaning system, re-attach tube (“IN”) to FILL VALVE NIPPLE (see Diagram 1). Be sure toilet tank flushing components move freely (if you don’t have a cleaning system, continue to Step 13).
13. Remove and discard overflow pipe cap if present. Attach one end of black REFILL TUBE to ANGLE ADAPTER and the other end to NIPPLE located near top of VALVE. Attach ANGLE ADAPTER to OVERFLOW PIPE. Trim REFILL TUBE as necessary to prevent kinking. NOTE: Flow from REFILL TUBE must be positioned just above the OVERFLOW PIPE. Do not insert REFILL TUBE down into OVERFLOW PIPE below water level. This will siphon water down the OVERFLOW PIPE, which causes the VALVE to turn on and off as it tries to keep the tank full. Hot Water Heaters If the ANGLE ADAPTER cannot be used, you may need the Model 599 Refill Clamp (not included).
