General description
EWWD Frictionless Centrifugal Chillers are complete, self-contained, automatically controlled, fluid-chilling units featuring
oil-free, magnetic bearing compressors. Each unit is completely assembled and factory tested before shipment.
Magnitude chillers are equipped with one or two compressors operating in parallel with a single evaporator and single
condenser.
The chillers use refrigerant R-134a that operates at a positive pressure over the entire operation range, so no purge
system is required.
The controls are pre-wired, adjusted and tested. Only normal field connections such as water piping, relief valve piping,
electric power and control interlocks are required, thereby simplifying installation and increasing reliability. Necessary
equipment protection and operating controls are included.
All chillers are factory-tested prior to shipment and must be commissioned by a trained service technician. Failure to
follow this startup procedure can affect the equipment warranty.
Receiving the machine
The machine must be inspected for any possible damage immediately upon reaching its final place of installation. All
components described in the delivery note must be carefully inspected and checked; any damage must be reported to
the carrier. Before connecting the machine to earth, check that the model and power supply voltage shown on the
nameplate are correct. Responsibility for any damage after acceptance of the machine cannot be attributed to the
manufacturer.
Checks
To prevent the possibility of incomplete delivery (missing parts) or transportation damage, please perform the following
checks upon receipt of the machine:
a) Before accepting the machine, please verify shipment documensts and chechs the number of shipped items
b) Check every single component in the consignment for missing parts or for any damage.
c) In the event that the machine has been damaged, do not remove the damaged material. A set of photographs are
helpful in ascertaining responsibility.
d) Immediately report the extent of the damage to the transportation company and request that they inspect the
machine.
