Notes
For compliance to ASSE 1061 a pipe insert (provided) must be
used with each connection when joining PEX pipe.
A collet cover is provided for each CTS connection and is
intended to prevent accidental disconnection of fitting during
pull-through installations while the system is unpressurized. To
disconnect the fitting, manually remove the collet cover and
depress the collet.
