ProFlo M-500 Series Installation Instructions

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.
