INSTALLATION
Install to a convenient ½"–1½" nominal water line, nearest the trap or traps to be served. Install in the upright, vertical position only. Install at least 5" (127 mm) above the grid of the floor drain or the flood rim of the sink or fixture which the trap serves. Install near plumbing fixtures to insure a full pressure drop of 10 PSI or more. If the trap primer is installed too far upstream in the system, the pressure drop may not be enough for activation. To help prevent sediment buildup, install a vertical loop that rises above the supply line tee. (see figure 1) Flush trap primer branch line prior to installing the trap primer. Install MIP adapter. Thread on trap primer. Install FIP union to bottom. Use PTFE tape sealant on both connections. Do not use pipe dope. Do not solder or braze directly to trap primer or fittings installed in trap primer. Water discharge is factory set—no adjustment is required on normal installations. However, for static pressures over 100 PSI, adjustments may be necessary. First loosen the nipple locknut (10, below), then turn the nipple (19, below) counter-clockwise until the trap primer starts dripping, turn the nipple clockwise ¼-turn, and re-tighten nipple locknut.
