IV. REPLACING TUBING
To disconnect tubing, push in the plastic
collet of the push-to-connect and pull out
the tubing.
Replace damaged tubing with replacement
sections in the field.
Regularly inspect the tubing ends for chemical
residue build-up, deep scoring, and kinks.
NOTE: Push-to-connect fittings are designed to score the
tubing to hold it firmly in place. Over time, the scoring
becomes deeper and can cause leaking with repeated
connecting and disconnecting. Restore bad tubing ends by
using a sharp box cutter, razor, or knife to make a straight,
vertical cut past the damaged section. Do not use scissors or
shears.

IV. REPLACING TUBING
To disconnect tubing, push in the plastic
collet of the push-to-connect and pull out
the tubing.
Replace damaged tubing with replacement
sections in the field.
Regularly inspect the tubing ends for chemical
residue build-up, deep scoring, and kinks.
NOTE: Push-to-connect fittings are designed to score the
tubing to hold it firmly in place. Over time, the scoring
becomes deeper and can cause leaking with repeated
connecting and disconnecting. Restore bad tubing ends by
using a sharp box cutter, razor, or knife to make a straight,
vertical cut past the damaged section. Do not use scissors or
shears.

remove tubing and tees.
NOTE: To use a push-to-connect, press and hold
down the plastic collet and pull out the tubing.
7.
Lay the Q-connect harness around the base of the
tree. Ensure both ends of the harness are con-
nected (connector should “click”) and the harness
is connected to the bottle.
