Operation
• If the compressor has been stored at an extremely low
temperature, allow it to heat to room temperature before
switching it on.
• The cut-in and cut-out pressure is preset from the factory
and it is normally not necessary to change this.
However, if it is necessary to change the preset settings,
the instructions of this manual shall be followed carefully.
• All AC compressors are designed for 100% duty but 50%
operation is recommended to prolong the lifetime.
• The fans on the back of the cabinet will start when the
temperature exceeds 0°C. It will run continuously even if
the compressor may have switched of until the temperature

• Do not lubricate the oil-less motor with oil, as it will destroy
important components.
