PFTP3500
Trap Primer Valve
With Adjustment Screw
Installation Instructions
A 1-1/8” open end wrench should be used to install the PFTP Series of trap seal primers to the line by using the flats on the top of the trap seal primer. Water lines must be flushed before installing the PFTP Series of trap seal primers. The trap seal primers should be cycled at least six times to ensure optimum performance. Ensure that all flux and other debris is removed. Use only teflon tape around threads. Do not use pipe dope. Do not solder fittings directly onto the inlet or outlet of the primer. Failure to follow these instructions will negatively affect performance of the product. The primers have a unique design which allows the primer to be taken apart and cleaned before re-assembly. Do this in the event of excess water discharge. Do not install the trap seal primers closer than forty feet apart when using the same potable water supply line. The device should be located within 20 feet of the valve or faucet for optimal discharge. Trap seal primers should be mounted one foot above the finished floor for every twenty feet of floor drain trap make-up water line. For easy assess to the trap seal primer, install a union connection above it. Install a line shut off valve upstream of the trap seal primer in order to shut off the water supply when performing maintenance on the trap primer. There is a 1/2" M.I.P. connection at the top of the trap seal primer and a 1/2" F.I.P. connection at the bottom of the trap seal primer.
Inspection Instructions
After installing and pre-cycling the trap seal primer, use any of the four holes to view water discharge from the orifice. A light can be placed opposite the observed view hole to improve clarity in this inspection.
Maintenance Instructions
In order to replace the filter screen, remove the trap seal primer by using an open end wrench on the top
set of flats. Grasp the top of the filter screen with fingers, squeeze and remove filter. Insert the new filter screen by squeezing and pushing it firmly down into the top of the trap seal primer. Re-install the trap seal primer using the top set of flats. In regions that experience heavy residual deposits such as calcium in the water supply, the PFTP Series of trap seal primers can be field refurbished by removing the bottom end of the primer and replacing the cartridge.
