InRoom CW/DX – Operating Instructions

Controller, Start/stop-key

• Adjust the return air temperature at the controller.

• Start the cooling unit by pressing the Start/Stop-key on the controller.

• After 20 minutes of operation, check whether bubbles are visible in the sight glass of the liquid line. If

this is the case, refrigerant might have escaped by a leak. Check the circuit for leaks, eliminate these

and charge the system with additional R407C refrigerant, if necessary. See "Maintenance", beginning

on page 76, for additional information.

• Check the oil level at the compressor.

The oil level should be between the lower quarter and the middle

of the sight glass.

• Check the current consumption of the compressors and the fans,

comparing it with the values of the technical data.

• Teach the operational staff how to use the controller (refer to the

controller manual).
