1.3 Site requirements
· Hard, level surface.
· Clean, dust free environment. Air-cooled chillers move large volumes of air, and
large amounts of air-borne contamination will result in fouling of the condenser.
This will reduce the capacity of the unit and in extreme cases cause a system shut-
down.
· Non-condensing ambient, from +4°C to +40°C. Maximum cooling capacity is
achieved at 22°C, and will de-rate by 2% per °C until capacity is lost at 30°C.
· Electrical supply. Two standard versions are available, 230V 50Hz 3A or 115V
60Hz, 6A. Other options are available on request.
· Clearance front and rear of the unit at least 250mm (10 inches).
· Plumbing to be clean and compatible with the fluid to be used. It is advisable that
the minimum of right angle bends and compression fittings are used to reduce
pressure losses in the pipework. See also section 2.0
2.0 Installation
Having ensured that your installation meets all of the site requirements identified in section
1.3, it is best practice that the fluid lines between your application and the chiller have the
following characteristics.
Fluid line requirements
· As short as possible. Ideally between 1 and 2 metres (between 3 and 6 feet).
· Large diameter. Ideally at least 12mm (½ inch) internal diameter
· Black tubing, to inhibit growth of algae. Alternatively, use solid copper or welded
ABS.
· Free from right angle bends
· Clean. If your installation is to existing pipe work, the system should be flushed
clean prior to filling. Hexid fluids are the recommended coolant choice as they
