Application Recommendations
NEVER
use NONEL EZTL detonators with detonating cord. The low strength
surface detonator will not initiate detonating cord.
ALWAYS
ensure the shock tube(s) are securely inserted, one at a time, into the
plastic EZ connector. The head of the connector block should rise to accept the
tube, and return to a closed position with an audible click.
ALWAYS
ensure the individual shock tubes remain aligned side by side in the EZ
connector channel and do not cross over one another during insertion.
ALWAYS
protect the plastic EZ connector and all shock tube leads from impact or
damage. Use care when placing blasting mats and cover material on top of the
blasting circuit. The EZ connector contains a detonator and is subject to
detonation caused by abuse such as impact. Shock tube which has been cut,
ruptured or damaged may cause misfires.
NEVER
attempt to disassemble the delay detonator from the EZ connector block
or use the detonator without the connector.
NEVER
place more than six shock tube leads into an EZ connector block. Misfires
may result.
NEVER
tie-in NONEL EZTL units until all holes have been primed, loaded,
stemmed and the blast site has been cleared.
NEVER
connect NONEL EZTL units with other manufacturers products as they
can be incompatible and misfires can occur.
Shelf Life -
For maximum shelf life (3 years), NONEL EZTL must be stored in a
cool, dry, well ventilated magazine. Explosive inventory should be rotated. Avoid
using new materials before the old. Accuracy of delay detonators may deteriorate
with age and stocks should be rotated regularly.
Application Recommendations (continued)
Using the Figure 80 Wind -
The Figure 80 wind may be reliably deployed by
removal of the securing sleeve or by drawing either end from the sleeve, the
remaining tube length will be retained in the sleeve.
Connecting NONEL tubes into the EZ block -
Form each tube into a loop and
pull it firmly into the NONEL EZ connector block until an audible
‘click’ is heard.
This indicates you have correctly inserted the tube.
•
Insert tubes one at a time to avoid crossovers in the block.
•
After inserting all tubes slide the block along the tubes to ensure that all are
fully engaged and any crossover is removed.
•
DO NOT double wrap tubes into the block.
•
Ensure that all tubes leave the block correctly and do not allow tubes to loop
back near the block. Keep tubes neat between holes, taut but not tight.
Disconnecting NONEL tubes from the EZ block -
If a tube has to be
disconnected from a EZ block, follow these steps:
1. Hold the tube to be disconnected in a firm position at one side of the block.
2. Fold the tube back into the beak area towards the opposite side of the block.
3. Use your thumb to gently push back the beak.
4. Gently pull the tube under the beak and out of the block.
If there are several tubes connected in a block, we recommend that tubes are
removed one by one, until the tube that has to be disconnected is removed.
Avoid excessive force, as this may damage tubes or the retaining mechanism in
the block. Make sure that all the tubes, except the one to be disconnected, are
reconnected to the block using the above steps.
