INSTALLATION
The following diagrams show the Harmsco BC4 Housings with typical plumbing
hook-up requirements.
Note: Do not install the unit in direct sunlight.
Do not install near a heat source.
1. Install incoming water supply to 2” FNPT coupling marked "Inlet".
2. Install outlet line to 2" FNPT coupling marked "Outlet", use stainless steel fit-
ting.
3. Install valves in drain lines and connect to 1/2" FNPT couplings located at
the bottom center and side of housing. Use stainless steel fittings.
Note: It is recommended to plumb a by-pass line to
supply unfiltered water while servicing if necessary.
4. Mount and secure housing using the three slots at the bottom of the legs.
See Installation Diagrams.
5. A qualified technician should make all connections.
6. Ground the filter housing utilizing the grounding lug on the leg.
7. Make sure housing’s cartridges,
lid and clamp-band are properly
positioned, see the Filter Car-
tridge Maintenance Instructions.

OPERATION
Description:
The BC4 series filters come in three sizes, BC4-1, -2 & -3,
which represent the number of levels of #801 cartridges, and consists of
a housing, lid, lifter rods (qty 4), top plate assembly, and a clamp band &
O-ring housing seal. Each level will contain four cartridges that are inter-
nally supported by the lifter rod and are sealed to the housing by the top
plate assembly to prevent by-pass. The housing is divided into two
chambers; an upper, “inlet”, chamber, which Is where the cartridge filters
are, and lower, “outlet”, chamber. All metallic components are made of
300 series stainless steel.
The cartridges (filter cartridges) are sold separately and avail-
able in a wide variety of materials and functional pore sizes. Please con-
sult with your Sales/Application Engineer to properly select the correct
filter that will achieve your desired requirements.

OPERATION cont.
Water enters the housing through the inlet located in the up-
per chamber. There is a baffle that protects the cartridges from the force
that is generated by the inlet flow. Once in the upper chamber, the water
must then flow through the filtering media of the cartridges and up to the
open end of the lifting rod located in the center of each cartridge. Water
will then enter the inside of the lifting rod and travel down and through
the housing’s tube sheet to the outlet chamber and then to the outlet
port. The tube sheet is integrally welded to the housing and contains
sealing cups that work in conjunction with similar features in the top
plate assembly to create and maintain the necessary bypass seals. The
cartridge end caps seal against themselves when assembled.

THE FOLLOWING INSTRUCTIONS MUST BE READ AND FOLLOWED PRIOR TO USE.
Filter Cartridge Maintenance Instructions: For Filter Housings With “V” Shaped
Band Clamp Closure.
1. Always Remove Pressure From Housing Before Servicing. Housing is to be shut off
and drained of fluid.
2. Open filter housing by turning clampband "T" handle counter-clockwise.
3. Remove cartridges from packaging.
4. Make sure center cores are clear of all obstructions, mainly from shipping materials.
5. Insert Cartridges into housing and onto lifting rods. First cartridges should come into
contact with sealing cup of housing.
6. Position housing O-ring seal on flange and outside of housing wall.
7. Place Lid onto housing and properly align on seal before applying clampband. Do not
allow tilting or cocking of Lid on gasket.
8. Position V-Band Clamp around housing and make certain clamp envelopes housing
flange and lid flange. Tighten V-Band Clamp slowly ensuring proper engagement of
clamp to flanges. Continue tightening clamp closure bolt. You might have to tap the
clamp in an inward radial direction, and all around its circumference, with a mallet to
prevent sticking between clamp and flanges.
9. Open Filter Housing Outlet valve.
10.Slowly open inlet valve to begin operation, allowing fluid to fill housing.
11.It is recommended to flush all air out of the system by running water through the filter for
about 30 seconds to one minute.
12.Start pump, if applicable, and operate filter.
Should a leak appear at the clamp, relieve pressure and repeat steps 8 through 11.
Always remove pressure from housing before servicing any part of filter.
