Installing Connector Blocks and Steam
Traps on Connector blocks
Standard
The Standard connector block should be installed in piping with the flow direction stamp pointing in the correct direction as
indicated on the connector block.
• The trap will then be bolted to the connector block after the connector block has been installed.
• When installing the trap to the connector block, apply 35-50 ft-lbs of torque to the bolts using a 9/16” wrench. Allow
2.5” clearance for bolt installation and removal.
• When starting a trap, be sure to open the valve slowly.
Note: Armstrong strongly recommends adding an upstream strainer and isolation valves upstream and downstream of the
trap. Refer to figures 4.1 and 4.2.
IS2
The IS2 connector block should be installed in piping with the flow direction stamp pointing in the correct direction as
indicated on the connector block.
• The trap will then be bolted to the connector block after the connector block has been installed.
• When installing the trap to the connector block, apply 35-50 ft-lbs of torque to the bolts using a 9/16” wrench. Allow
2.5” clearance for bolt installation and removal.
• When starting a trap, be sure to open the valve slowly.
Note: Armstrong strongly recommends isolation valves upstream and downstream of the trap. Refer to figures 5.1 and 5.1.
