Electrical Connections; Routine Leak Testing; Condenser Fan(S) & Motor(S); Certification & Approval - Emerson Copeland Eazycool OMTE-90D-TFD Application Manuallines

As a rule, and for a clean environment, Emerson recommends that the fins be cleaned with liquid
detergent diluted with clean water. The condensing unit has a well-designed chassis, and provided
the unit is installed level, any cleaning solution should be able to drain away. A light brush downward
(in the direction of the fins) should be done before washing to remove heavy deposits.

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 EazyCool Large Outdoor
Condensing units are no exception. Over time, due to these slight vibrations and to temperature
fluctuations within the unit housing, electrical terminations may become loose. The components most
likely to be affected are the main terminal strip and the compressor contactor. It is recommended 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.
In all cases, if metal covers (with grounding connections) have been removed for maintenance, all
grounding connections have to be reconnected before unit operation when the covers are put back
in place.
5.5

Routine leak testing

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.
All joints inside the system should be leak-tested as part of a regular maintenance schedule.
5.6 Condenser fan(s) & motor(s)
A yearly inspection of these items is recommended. Fastenings can become loose; bearings may
wear 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.
6 Certification & approval
▪
Copeland EazyCool Large Outdoor Condensing units comply with the Low Voltage Directive
LVD 2014/35/EU. The applied harmonised standard is EN 60335 (Safety Household and Similar
Electrical Appliance, Part 2-89: Requirements for commercial refrigerating appliances with an
incorporated or remote refrigerant condensing unit or compressor).
▪
The piping complies with the Pressure Equipment Directive PED 2014/68/EU (Art.3 §3 - Sound
Engineering Practice).
▪
The refrigeration units and their components as far as required are CE marked and thereby
establish conformity with the relevant directives.
▪
Conformity Declarations for components are available as far as required.
