WATER SYSTEM DATA
When all the pipework has been connected in the system, proceed as follows:
Pressure Testing
•
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.
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.
CAUTION
All free-cooling units should use minimum 20% glycol concentration.
Filling
CAUTION
It is recommended that the whole system 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 tubes in the cooler.
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.
Auto air vents are fitted, Airedale strongly recommends an auto pressurisation unit be
fitted to the system.
