NOTE: In order to meet the requirements of the Ecodesign Directive 2009/125/EC with
regard to efficient system operation, ensure the heat exchangers remain clean at all times.
5.4 Electrical connections
WARNING
Isolating switch "On"! Danger of electric shock!
Before undertaking any
task on electrical equipment, turn off the main power supply to de-energise
the unit.
All condensing units will generate some degree of vibration. Copeland ZX Small units are no
exception. However, the vibration level from the compliant scroll technology is less severe than in
units using reciprocating compressor technology. Thanks to this reduced vibration, ZX Small
refrigeration units can be mounted on simple, less expensive rubber mounting pads.
Nevertheless, over time, due to these slight vibrations and to temperature fluctuations within the
unit housing, electrical terminations might become loose. The components most likely to be
affected are the main terminal strip and the compressor contactor. It is suggested to check the
main electrical terminations for tightness and to carry out a visual inspection of the low voltage
crimped terminals at least once every 6 months.
5.5 Routine leak testing
All joints inside the system should be leak-tested according to EN 378-4 as part of a regular
maintenance schedule.
NOTE: In order to meet the requirements of the Ecodesign Directive 2009/125/EC with
regard to efficient system operation, ensure the refrigerant and oil charges are sufficient.
5.6 Condenser fan & motor
A yearly inspection of these items is recommended. Fastenings can become loose, bearings may
wear out and fans may require cleaning of solid deposits that can cause rotational imbalance.
Motors come with lifelong lubrication bearings that do not require lubricating on a routine basis, but
just need to be checked for wear.
