Installation Data
Chilled water pipework and ancillary components must be installed in accordance with:
National and Local Water supply company standards
The manufacturer's instructions are followed when fitting ancillary components
The system liquid is treated to prevent corrosion and algae forming
Glycol required as standard, with the correction concentration to suit the lowest
ambient the equipment will experience
WATER SYSTEM
The schematic is referred to as a guide to ancillary recommendations
CAUTION
The unit water connections are NOT designed to support external pipework,
pipework should be supported during installation.
STANDARD RECOMMENDED INSTALLATION
CAUTION
The following installation recommendations should be adhered to. Failure to do
this will invalidate the chiller warranty.

Following components are fitted within the chiller unit as standard:
Temperature Sensors
Drain Point
Auto Air Vent
Flow Switch
CAUTION
20 Mesh Inlet Filter
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.
Component
Recommended
Requirements
A flow switch or equivalent, fitted adjacent to the water outlet side of the Chiller.
CAUTION
Constant water flow MUST be maintained. Variable water volume is NOT
recommended and may invalidate warranty.
CAUTION
The correct operation of the flow switch is critical if the chiller warranty is to
be valid.
A water-flow commissioning valve set fitted to the system.
In multiple chiller installations, 1 commissioning valve set is required per chiller.
Air vents are to be installed at all high points and where air is likely to be trapped at
intermediate points.
Drain points are to be installed at all low points in the system and in particular
adjacent to the unit for maintenance to be carried out.
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.
