Specific conditions for use may apply for ATEX/UKEX and IECEx.
Warning: To prevent electrical shock, short circuit or arcing, this product must be installed correctly and water ingress must be avoided before and during the installation.
Warning: The purchaser should make the manufacturer aware of any external effects or aggressive substances that the equipment may be exposed to.
Before installing this product, read the installation instructions completely.
Caution: Prolonged or repeated contact with the sealant in the core sealer may cause skin irritation. Wash hands thoroughly. Overheating or burning the sealant will produce fumes that may cause polymer fume fever. Avoid the contamination of cigarettes or tobacco. Consult MSDS VEN 0033 for further information.

Specific conditions for use using ATEX/UKEX or IECEx approvals:
For ambient temperatures >+40°C:
Use a power cable with continuous temperature resistance of minimum +90°C
Use a metallic power cable gland approved for use in hazardous areas (for example GL-38-M25-METAL).
For voltages >254 Vac and BTV, QTVR, XTV(R), KTV or HTV heating cables:
- Use a power cable with continuous temperature resistance of minimum +90°C
- Use a metallic power cable gland approved for use in hazardous areas (for example GL-38-M25-METAL).
- For pipe temperature > 150°C and XTV(R), KTV or HTV heating cables, the maximum operating current shall be reduced to maximum 20 A.
Installation
Remove the tubes and dispose of them in the core sealer plastic bag. 
Install power cable and gland. Pull in power and ground wires, strip off 13 mm of insulation and terminate. (For -EP version only: connect earth plate to ground according to local requirements). 
Install lid.
- τ = 1.02 to 1.47 Nm
- Apply insulation and cladding. Weather seal the stand entry. Leave these instructions with the end user for future reference.
