Requirements The recommended requirements to allow commissioning to be carried out correctly are:

The inclusion of Binder Points adjacent to the flow and return connections, to allow
temperature and pressure readings

A flow switch or equivalent, fitted adjacent to the water outlet side of the unit Chiller

A water-flow commissioning valve set fitted to the system

In multiple chiller installations, 1 commissioning valve set is required per chiller

Isolating valves should be installed adjacent to all major items of equipment for ease
of maintenance

Balancing valves can be installed if required to aid correct system balancing

All chilled water pipework must be insulated and vapour sealed to
avoid condensation

If several units are installed in parallel adjacent to each other, reverse return should
be applied to avoid unnecessary balancing valves
