Installation Instructions
Install feeder as illustrated. If boiler tappings for equalizing pipes “A”
and “B” are not available, connect either one or both as shown by
dotted lines.
Install with “water line” mark on fl oat chamber on a level with the
middle try-cock, or about halfway up the gauge glass.
Connect water supply line “C”. If a strainer is used, install it in this
line. Connect feed line “D” from valve to bottom of boiler.
Install by-pass “E” so that boiler can be fi lled by hand if necessary.
All valves should be tight-closing and of good quality. Leaky valves
will fl ood boiler.
Blow down fl oat chamber at least once a week by opening valve “F”
and letting water run for a few minutes.
A shutoff and check valve must be installed in the water supply line
“G”.
For pressing machine and other small process boilers.
Water is automatically supplied to the boiler as needed
to maintain boiler water at the correct working level.
Feed valve is fl oat-operated and simply constructed.
Can be easily cleaned if fouled by dirt in the water sup-
ply.
Water is fed to the boiler through an independent con-
nection to the bottom of the boiler.
