REFRIGERANTPIPE

If the frequency conversion multi-training system, the combination ration of the indoor unit and the outdoor unit should satisfy the following conditions:

Remark:1, the N% value is 100%, if the indoor unit is not always fully turned on, N% can be 130%.2, the maximum cooling capacity of the unit is equal to the rated cooling capacity of the outdoor unit;3, it is recommended to minimize the number of indoor units and the length of the pipeline as short as possible.

REFRIGERANT PIPING

UNITINSTALLATION

The base is sufficient to withstand the weight and to isolate noise and vibration;Avoid direct sunlight, and if necessary, make a sunshade;The installation must be able to exclude rainwater and water formed by defrosting;The installation must ensure that the machine is not buried in the snow;The installation must ensure that the air outlet does not face strong winds;Ensure that the unit’s air and operating noise do not affect neighbors;The installation location must be free of debris and oil mist.For installation, please check with local service or dealer.

Warning :If the outdoor unit is operated in an atmosphere containing oil source(including oil), salt(marine areas), sulfide gases(in the vicinity of hot spring, refineries) these substances may cause unit failure.
