Surely carry out high-quality pumping of air from a refrigerating contour before its charging coolant, otherwise the conditioner will fail.

It is necessary to consider two cases:

– pumping of air is made right after a contour discharge;

– pumping of air is made in several hours or days after a contour discharge.

Pumping of air is made right after a contour discharge.

Pumping of air is carried out within 20 min.

Pumping of air is made in several hours or days after a contour discharge.

Pumping of air is made within 45 min. completely to eliminate moisture traces.

Upon termination of pumping of air carry out an inspection of a contour on tightness (some charging stations do it automatically).
