Installation Data
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.
Component
Recommended
Requirements
• A flow switch or equivalent, fitted adjacent to the water outlet side of the Chiller.
CAUTION
The correct operation of the flow switch is critical if the chiller warranty is to
be valid.
• 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.
• 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.
When installing circulating water pumps or equipment containing them, the following rules
should be applied:
• Ensure the system is filled with water then vented and the pump primed with water
before running the pump. This is required because the pumped liquid cools the pump
bearings and mechanical seal faces.
Pump Statement
• To avoid cavitation the NPSH (Net Positive Suction Head) incorporating a safety
margin of 0.5m head must be available at the pump inlet during operation.
When all the pipework has been connected in the system, proceed as follows:
• Ensure all shut off and control valves are fully open.
• Pressurise system to the operating pressure, hold for 1 hour (a gradual fall in
pressure shown on the gauge indicates a leak).
• Leaks should be found and repaired and the unit pressure tested for a further hour.
Pressure Testing
When the pressure remains at the operating pressure for 1 hour, the system can be
considered leak free.
CAUTION
Although a pressure of 1.5 x working pressure is adequate for testing purposes,
most local water authorities require 2 x working pressure.
Filling
The whole system MUST be flushed prior to filling to remove debris left in the
water pipework by using a flushing bypass as shown to avoid serious damage to
the plate evaporator.
During filling the system should be vented at all high points.
Once the system has been completely vented all vents should be closed.
To prevent air locking in the system it is advisable to fill the systems from the lowest
point, ie drain point on pipework.
CAUTION
If auto air vents are used then we strongly recommend an auto pressurisation unit be
fitted to the system.
