The device should be left at rest for at least 2 hours after the completed installation before it is turned on (applies to devices with an internal unit), then the oil level is leveled and it prevents problems with the start- up of the refrigeration unit!
In devices with an internal unit special attention should be paid not to block the inlet holes in the aggregate chamber (perforation in the lower part of the rack), used for cooling the air of the unit. Accurate horizontal positioning of the rack prevents noisy operation and ensures proper water drainage during defrosting.

2.2 CONNECTION OF THE SEWING MACHINE.
During the cyclical defrosting process, the ice accumulated on the evaporator of the device melts.
The water created as a result of the process must be removed from the device. The place of removing water is the siphon located under the device.
