High-pressure filter
The machine has a high-pressure filter (see Figure 14) located in the high-
pressure line before the chemical injector. It has the following specifications:
Sintered 316 stainless steel filter element
Standard micron ratings include 1, 5, 10, 50 and 100
Pressure rating:
316 stainless steel – 6000 psig CWP
Brass – 3000 psig
Temperature rating:
Viton (-15° F to 400° F)
Buna-N (30° F to 275° F)
Ethylene propylene rubber (70° F to 275° F)
This filter traps any mineral chips or scale in that breaks loose from the I.D. of
the coil. If this debris is not filtered, it could plug the orifices in the chemical
injector. Service this filter weekly as follows:
1.
Remove the hose from the top of the filter.
2.
Remove the end cap and filter element (screen).
3.
Examine the filter element for damage. Do not reinstall a filter element
showing any sign of damage.
4.
If the filter element is intact, clean it, lightly grease the rubber seat
inside the end cap and replace the element. If the element is not intact,
obtain a replacement kit (element, spring, white ring) from PEM, and
replace it.
