2.6.2 Application limits

For application envelopes, please refer to the compressor application envelopes which can be
found in Copeland™ brand products Select software, available at www.emersonclimate.eu.
OM(T)E & OL(T)E condensing units can be used with an ambient temperature from -15°C to 45°C.
For lower ambient temperatures please contact your local Application Engineering representative.
WARNING
Compressor breakdown! Oil dilution due to low superheat! Low suction
superheat leads to oil dilution. Always operate the system with adequate
superheat to avoid viscosity decrease of the oil. Additional measures in
system design might help to avoid inacceptable lubrication conditions.

Main component description

2.7.1 Bill of material 501 – general description
OM(T)E & OL(T)E units have the bill of material 501. In general, those kind of units have an air
cooled condenser with 2 EC-fans for condensing temperature control.
A Tandem set of 2 Scroll-compressors (ZB** for OM unit, ZF** for OL unit) provides the required
cooling capacity. One of this compressor is always a Digital Scroll, which allows modulation to
very low part load conditions. Both compressors are equipped with a high efficient sound shell for
best sound performance.
An oil management system with oil separator, oil reservoir and oil injection devices secure
sufficient compressor oil levels.
Electronic controller XCM-25D is taking care for suction pressure regulation, fan speed control in
standard & heat recovery condition, as well as for system safety.
The main safety features provided by the unit: Compressor oil level control, discharge temperature
protection, voltage sensing, refrigerant charge level control & high and low pressure safety.

2.7.2 Housing

Large outdoor condensing units OM(T)E & OL(T)E with BOM 501 have additional housing
features:

New designed E-Box, accessible over hinged cover, adjustable in 2 steps (45° & 90°)

Service friendly accessible compressor chamber

Service friendly accessible liquid receiver/filter drier/sight glass area

Easy cleaning of condenser section
