HEALTH AND SAFETY WARNING The resin used in the compound can cause eye and skin irritation. For
your personal protection, wear the gloves supplied while mixing and applying. The uncured compound
should not be allowed to come into contact with foodstuff.
A COMPREHENSIVE SAFETY DATA SHEET PROVIDED BY THE COMPOUND MANUFACTURER IS AVAILABLE
ON REQUEST.
5. Check compound has not passed its
“Use By”
date. Installation at temperatures below 10 °C should be avoided if possible.
6. Trim any hardened pieces from ends of stick. Mix the compound by rolling, folding and breaking. Ease mixing by cutting
large sticks in half. Fully mixed compound has a uniform yellow colour with no streaks.
7. Support the cable and Rear Assembly, holding them roughly concentric. Any lead sheath should be pushed through the
continuity washer – ensure that contact has been made. Splay out the cores. Starting at the middle, pack small amounts
of rolled-out compound between the cores. Restraighten each core and work outwards until all gaps are filled. Bundle the
cores with cord or tape so they are not disturbed. Pack around the outside of the outer cores to completely fill the Rear
Assembly cup. Build up compound around the outside of the cores, with a slight taper & to approximate compound length
shown in diagram & Table 1 column 7.
8. Pass cores through & push compound into Entry Body until Rear Assembly engages. Remove squeezed out compound at
arrow A. Screw Union Nut 7 full turns onto Entry Body
(arrow B).
Ensure that compound emerges at entry thread
(arrow C).
9. Clean off excess compound from Entry Body to allow withdrawal when cured (arrow C). Cores may be disturbed after
1 hour. Leave to cure for 4 hours when working at 21 °C.
10. To release and pull back joint for inspection, unscrew Union Nut. Ensure that the compound is uniform and full form to fit
into the entry body.
11. Hand-tighten Union Nut to remake joint. Then refer to table below table and tighten Union Nut using wrench to the given
amount.
12. Hold Mid Cap with wrench and tighten Back Nut onto cable. Ensure seal makes full contact with cable sheath, then tighten
1 extra turn.
13. The equipment should not be energised until the compound has been left to cure for at least 4 hours when working at
21 °C. See chart ´Energising Time vs. Temperature´ for further guidance.
