First steps
When receiving the unit, please do the following:
✓ Check the integrity of the unit's transport packaging.
✓ Check if the unit is pressurized with 2 bar nitrogen.
✓ For the OME-16T model only, remove the transport bracket from the unit. Please refer to Figure 1 below and
to section 3.6 "Transport bracket" in the unit's application guidelines for more information.
Figure 1: Transport bracket on the OME-16T model
✓ Follow the instructions in the application guidelines when dealing with BOM version OM(T)E-**T-TEM-*-2**
(split/flexible models).
The piping between the unit and the evaporators shall be designed taking into account the design pressures.
If the system piping design pressure (PS) is lower than 90 bar in the liquid line, additional safety devices are required.
An additional safety device in the suction line is required in any case.
The minimum required design pressure (PS) is 80 bar for the liquid line and 60 bar for the suction line. Longer
standstill times of the unit can be achieved by a design pressure of more than 60 bar in the suction line.

  • Page 5 Evacuation IMPORTANT The evacuation procedure is based upon achieving an actual system vacuum standard and is NOT TIME DEPENDENT! The installation must be evacuated with a vacuum pump before commissioning. Proper evacuation reduces residual moisture to 50 ppm. The installation of adequately sized access valves at the furthest point from the compressor in the suction and liquid lines is advisable.

    4) Click on "ENABLE". " " Figure 9: Enable button in the evacuation menu 5) The flashing "EVACUATION" on the main page indicates that the evacuation mode is active. Starting the evacuation mode: The evacuation mode will start when clicking on "ENABLE" only if the suction, discharge and liquid receiver pressures are below 10 bar.

First the gas cooler fan(s) start(s) up, then the compressor(s) switch(es) on and start(s) controlling according to the suction pressure.
  • Page 8 Copeland recommends charging the liquid receiver only up to 60 %. Charging must be done with compressor(s) switched on. NOTE: Never charge the system to a liquid level higher than the upper sight glass of the liquid receiver.
