Installation and operating instructions, General specifications, Connecting the filter
These quality engineered, high-flow filters in 304 Stainless
Steel are widely used and recommended for “Central
Filtration” systems such as required for apartment buildings,
schools, clubs, camps, institutions, farms, restaurants and
cafeterias where outside building installations require flow
rates from 28 - 125 gpm (1,580 - 7,500 gph), when installed
with PENTEK dirt/rust cartridges (Models S1 or P25) for cold
water installations up to 100° F (38° C).
When used with PENTEK taste/odor Model C1 cartridges,
flow rates will range from 12 - 60 gpm (720 - 3,600 gph).
All 304 Stainless Steel filters are shipped without
cartridges installed, featuring a single clamp for fast and
easy removal of the cover.
The internal center rod features a tightening hand knob to
facilitate fast cartridge change-over and sealing. Rated flow
capacities are based on sediment removal with
25-Micron Rated filter cartridges.
* Above Rated Capacity based on sediment removal with a 25-Micron filter cartridge and 1 psig initial clean pressure drop. For taste/odor removal, rated flow capaci-
ties based on effective contact time are: ST-BC-4, 12gpm; ST-BC-5, 15 gpm; ST-BC-8, 24 gpm; ST-BC-10, 30 gpm; ST-BC-12, 36 gpm; ST-BC-15, 45 gpm; ST-BC-16, 48 gpm;

WARNING: The housing MUST BE protected against freezing. Failure to do so may result in cracking of the housing and leakage.
WARNING: If pressure may exceed 125 psi at anytime, a pressure regulator MUST BE used.
WARNING: After opening to install cartridges, make sure to replace cover according to instructions, or it will leak under pressure.
WARNING: DO NOT use air to test housing for leaks.
WARNING: DO NOT use housing for air filtration.
The filter should be mounted in an elevated position permitting
easy draining. The drain plugs located on the filter wall should
be removed, and piping with drain valves installed as in Fig. 1 or 3.
Identify inlet and outlet connections (inlet is always higher
than the outlet).
TAKE CARE NOT TO HOOK THE FILTER UP BACK-
WARDS. Place filter as shown and connect piping, being sure
to install a shut-off valve on each side of the filter. NOTE:
When filter is installed next to the water meter or pressure
tank, the main shut-off valve serves as pressure-side (filter
inlet) shut-off.
