IMPORTANT NOTE
: When replacing a Copeland 4DL 1500, or 4DP 1500 series
compressor the IR4B3139Q series IR Impact compressor must be used. If the P series is used
the suction service valve from the 4D will not fit and will require suction line re-piping.
10. Larger capacity compressors
require the large 2 1/8” suction
valve with a 3 1/8 flange vs. the
2 1/8” suction valve with the
2 11/16 flange.
The larger valve will require a
spacer which allows the valve to
be positioned above the valve
well to accept the larger valve
flange.
The spacer ( A ) requires two
gaskets ( B ) shown in figure11
All other suction valve sizes do
not require a spacer and will fit
in the suction well using a
single gasket.
` Figure 12
11. The upper suction gasket has a tendency to
move when the valve is placed on the
suction flange.
Installation Tip:
Place the bolts in the suction valve and
Screw them into the flange about 1 -2 turns.
Center the gasket between the suction
spacer and the suction valve with a
screwdriver while lifting up on the valve.
Tighten the suction valve bolts evenly.
