every two weeks in a room with the temperature above 0°С.
3. In case of warehousing stor
age (at the ambient temperature above or below 0°С), the
periodic start-up of the compressor is not required.
Recommendations for maintenance of the air conditioning system
1. Perform filling of the system with R134a Freon gas in the capacity of 950 g.*
2. The filling the system with Freon gas and replacement of system units shall be
