Remove the unit from its original packaging and ensure that there is no packaging left
around the cooling ducts.
Please retain all packaging in the unlikely event that the chiller needs to be returned to
our local representatives.
1.3 Site requirements
Hard, level surface. Ideally smooth, to allow freewheeling of the castors, which
are designed for indoor use.
Non-condensing ambient, from +4C to +40C, ideally indoors. Cooling
capacity is lost above 30C.
Clean, dust free environment. Air-cooled chillers move very large volumes of
air. Large amounts of air-borne contamination will result in fouling of the
condenser, reducing the capacity of the unit, and extreme cases may cause a
system shut down.
Water supply (applies only to water cooled chillers). Water cooled K series
chillers up to and including the K6 all require clean process water at a flow rate of
at least 10 litres per minute at a pressure of not less than 1 bar (15psi). The
systems are designed for water to the chiller at 15C. If the water available does
not meet these requirements, please consult ATC for specific advice regarding
your installation. Please have the following information available: (i) cooling
water flow, (ii) cooling water pressure, (iii) cooling water temperature and
(iv) chiller serial number.
Suitable power. The supply requirements can be determined from the details
printed on the rating plate. All ATC units are designed for a –15% to +10%
fluctuation in supply voltage. Ensure that the house supply circuit breaker is
suitably rated and is of the slow-blow type, since the chiller is capable of
momentarily drawing ten times the current shown on the rating plate at startup.
Clearance front and rear of the unit at least 500mm.
