Connect tubes to the pump and install a check valve.
Before operation
• Cut the tube ends flat.
Necessary tools
• An adjustable wrench or spanner.
Tube connection
a. Pass a tube into the fitting nut and stopper and then slide it down
to the adapter as far as it will go.
b. Put the tube end (adapter) in the fitting. Then hand tighten the
fitting nut.
c. Retighten the fitting nut by turning it further 180 degrees with an
adjustable wrench or spanner (crush tube mount).
*
Do not use excessive force to the plastic fitting nut.
* In your try to remove the connection, the adapter may be stuck in
the crushed tube and the stopper. Try not to damage the taper of the
adapter that is crushing the tube against the stopper. If it has been dam-
aged, contact us for the new adapter/stopper.
* Do not reuse the same tube end for the crush sealing. Cut it off for
ensuring the new seal is established.
