“Fusion” sequence
4.1
Siting, connection, and startup
Before every use, you should check that the FRIAMAT fusion unit is not
damaged and operates properly within the specifications. All parts must be
correctly installed and all conditions fulfilled. Only then can the device operate
properly.
The FRIAMAT fusion unit can be sited and operated out of doors when it is
protected against rain and moisture.
1. The FRIAMAT fusion unit must be sited on level ground.
2. Prepare the fitting and pipes for fusion in compliance with the assembly
instructions.
3. Make sure that the fitting’s contact pins are accessible for connection
to the fusion plugs.
NOTE
Danger of overheating in the cables!
Before use, all cables must always be unwound completely. This applies to the
device, fusion, and extension cables.
4. Connect the device to the power supply (mains or generator).
To do so, insert the device’s plug into the socket.
5. If necessary, use an extension cable. Make sure that the conductor cross
section is adequate (see also Section 2.6).
6. When operating with a generator, make sure that it is fused with at least
16 A (slow acting, see also Section 2.5).
7. When operating with a generator, first start the generator and let it warm
up for 30 s.
8. Switch ON the FRIAMAT fusion unit at its main switch.
NOTE
Danger of scorching!
The contact areas on the fusion plugs and fitting must be clean. Soiled contacts
can cause the plug to overheat, damaging it.
• If necessary, wipe clean of any contaminants.
• You must always protect the plugs against soiling.
• When a deposit has formed that cannot be removed completely, the fusion plugs
must be replaced.
• First examine the fusion plugs and the fitting’s insert contacts for soiling,
then connect them.
