Having ensured that your installation meets all the site requirements identified in section
1.2, it is best practice that the fluid lines between your application and the chiller have
the following characteristics:
• Short
• Large diameter (ideally at least 12mm internal diameter)
• Free from right angle bends, to suppress water hammer and reduce pressure
losses
• Opaque, ideally black, to inhibit growth of algae. Alternatively, use solid copper or
welded ABS. Caution: Never use transparent tubing.
• Clean. If your installation is to existing pipe work, it is good practice to flush the
system with either a commercially available central heating cleaner or 5% acetic
acid solution. The system should be flushed clean with tap water to remove all
traces of cleaner prior to filling the system.
All connections should be made using either the ATC ‘easy clamp’ or a jubilee type clip.
Where threaded or compression type fluid joints are to be made, always use a suitable
jointing compound such as PTFE tape.
Voltage selection
Caution: If your KT1 series chiller is rated for multi voltage and dual frequency operation,
it is essential that the voltage selector switch on the chiller is set to match the voltage and
frequency available at your site.
The voltage selector switch can be found on the front of the chiller. Access is gained by
removing the two knobs on the front ventilation panel to expose the selector switch.
Confirm the required voltage setting, then always replace the cover for normal operation.
