Part A: Heating up phase
7. During the heating up phase tighten the welding tools carefully with
the Allan key.
Take care that the tools completely contact the heating plate. Never
use pliers or any other unsuitable tools, as this will damage the coating
of the welding tools.
8. The temperature of 260° C is required for the welding of aquatherm
PP-R pipes.
Acc. to DVS - Welding Guidelines the temperature of the welding
device has to be checked at its tool before starting the welding
process.
This can be done with a fast indicating surface thermometer.
ATTENTION:
First welding - soonest 5 minutes after reaching of the welding
temperature. DVS 2207, Part 11.
Part A: Handling
9. A tool change on a heated device requires another check of the
welding temperature at the new tool (after its heating up).
10. If the device has been unplugged, e.g. during longer breaks, the
heating up process, has to be restarted (see item 6).
11. After use unplug the welding device and let it cool down. Water
must never be used to cool the welding device, as this would
destroy the heating resistances.
12. Protect aquatherm- welding devices and tools against impurities.
Burnt particles may lead to an incorrect fusion. The tools may be
cleaned with aquatherm cleaning cloths, Art.-No. 50193.
Always keep the welding tools dry.
13. After welding, do not lay the the device on the Teflon coated tool,
but put it down in the provided supporting stand.
14. For a perfect fusion, damaged or dirty welding tools must be
replaced, as only impeccable tools guarantee a perfect connection.
15. Never attempt to open or repair a defective device. Return the
defective device for repair.
16. Check the operating temperature of aquatherm- welding devices
regularly by means of suitable measuring instruments.
