CAUTION
Full design water flow MUST be maintained at all times. Variable water volume is
NOT recommended and will invalidate warranty
The correct operation of the flow proving device is critical if the chiller warranty is
to be valid.
Following components are fitted within the chiller unit as standard:
•
Temperature
Sensors
•
Drain
Point
•
Auto Air Vent
WATER SYSTEM
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 20 mesh strainer fitted prior to the evaporator inlet
•
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
Component
Recommended
Requirements
•
If several units are installed in parallel adjacent to each other, reverse return should
be applied to avoid unnecessary balancing valves
