August 2007
BTAS Replaceable Suction Filter Cores or Suction Filter-Drier Cartridges
DO NOT OPEN BAG UNTIL READY TO INSTALL BLOCK OR SUCTION FILTER CORE
1. Pump down the system and the BTAS assembly completely.
2. Remove flange bolts (B), flange cover (C), spring (D), and
flange gasket (F).
3. Remove used suction filter core or filter-drier cartridge
(E).
4. Clean all internal parts thoroughly.
5. Remove the core cartridge from packaging and reassemble as rapidly as possible to minimize moisture
contamination.
6. Lubricate the new neoprene gasket (F) sparingly with
refrigerant oil, and place in groove at the top of the shell
(G).
7. Install the filter core or filter-drier cartridge (E) with the
closed end toward the flange cover (C).
8. With the large end of spring (D) against flange cover (C),
push the flange cover (C) against the shell (G), being
careful to align the cover inside the gasket (F). Install two
flange bolts (B) in diagonally opposite holes to hold the
cover snugly against the shell (G).
9. Install the remaining 4 flange bolts (6 flange bolts for the
BTAS -5– series).
10.Torque all flange bolts evenly in a criss-cross pattern to
the following maximum torque:
BTAS-2: 12 Ft. Lbs.
BTAS-4: 20 Ft. Lbs.
BTAS-3: 14 Ft. Lbs.
BTAS-5: 50 Ft. Lbs.
11.Test for leakage.
12.Start the compressor and put the system in operation.
Record the pressure drop on the enclosed label (H) and
apply to the side of the shell (G) as shown.
WARNING: Do not use suction filter cores or filter-drier
cartridges on liquid line applications.

SAFETY INSTRUCTIONS
INSTALLING BTAS TAKE-A-PART SHELL
1. Read installation instructions thoroughly. Failure to follow
instructions may result in drier failure or system damage.
2. Do not remove blocks from bag until just prior to installation. Early removal could result in contamination of the
desiccant from surrounding atmosphere.
3. Check arrow for correct flow direction. Reverse flow may
cause internal damage.
4. CAUTION: In a severely contaminated system avoid
breathing acid vapors, and avoid contact with the skin or
clothing from contaminated refrigerant.
5. Thoroughly leak test system after installation. Failure to
do so could result in loss of refrigerant.
6. These products are intended for use on the following
refrigerants up to a maximum working pressure marked
on the product.
R-12: dichlorodidifluoromethane
R-22: monochlororididkuoromethane
R-500: by weight:
73.8% monochlorofiffluoromethane
26.2% difluroethane
R-502: by weight:
48.8% monochlorodifluoromethane
51.2% monochloropentafluoroethane
7. The product listed in this bulletin should not be used for
liquid line or hot gas operations.
1. Locate the BTAS shell in the suction line as close as
possible to the compressor, but upstream of vibration
eliminators. Install the shell in a vertical position, or in one
the two suggested positions shown which permit oil return
to the compressor and convenient installation of the core
or cartridge.
NOTE: "The side connection of the BTAS shell must
always be the inlet when using all cores and cartridges to
ensure compressor protection from possible rupture.
2. Remove the flange bolt (B), flange cover (C), spring (D),
and discard the flange gasket (F). See Figure 1.
3. Install the filter core or filter-drier cartridge as noted on
the reverse side starting with step 5.
