Connect and Disconnect Tubes
Follow these steps when connecting and disconnecting
any air tubes on the tandem DynaMite supply system.
Connection
1. Grasp the tube, then slowly push it straight into the
fitting until it stops.
2. Be sure that the tube is securely connected, and will
not pull out when air pressure is applied. To check,
pull gently on the tube.
Disconnection
1. Follow the Pressure Relief Procedure on page 12.
2. Push evenly on the fitting’s red release button.
3. While holding the release button in, pull the tube out
of the fitting.
4. To reuse the tubing, cut off the previous connection
portion at 90
°
, being careful not to damage the outer
diameter of the tube.
NOTE: Use of a tube cutter is recommended. The fitting
will leak if the tubing is not cut at 90
°
.
Flush the System
NOTE: The pumps in the tandem supply system are
tested with lightweight oil, which is left in to protect the
pump parts. If the fluid you are using might be contami
nated by the oil, flush it out with a compatible solvent
before using the pump.
Flush with a fluid that is compatible with the fluid you are
pumping and with the wetted parts in your system.
Check with your fluid manufacturer or supplier for rec
ommended fluids and flushing frequency. Always flush
the pump before fluid dries on the displacement rod.
Refer to DynaMite 190 Extruder Instructions - Parts
manual 308302 for instructions on how to flush the
DynaMite 190 Extruder pumps.
To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest pos
sible pressure.
NOTICE
Never leave water or water-based fluid in a carbon
steel pump overnight. If you are pumping
water-based fluid, flush with water first, then with a
rust inhibitor, such as mineral spirits. Relieve pres
sure, but leave rust inhibitor in the pump to protect
parts from corrosion.
