1.3 Site requirements
· Hard, level surface. Ideally smooth to allow freewheeling of castors, which are
designed for indoor use.
· 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,
reducing the capacity of the unit and in extreme cases causing a system shut-down.
· Non-condensing ambient, from +4°C to +40°C. Cooling capacity is lost above
30°C.
· Electrical supply 230V ±10% (50Hz) single phase

. Internal circuit breaker is
rated at 15 Amps, normal operating current is 7 Amps.
· Clearance front and rear of the unit at least 250mm.
· 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. See also

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:
· Short
· Large diameter (ideally at least 12mm internal diameter)
· Free from right angle bends, to suppress water hammer
· Opaque, ideally black, to inhibit growth of algae. Alternatively, use solid copper or
welded ABS. Caution: Never use transparent tubing.
