(*) The recommended oil for units with R410A refrigerant is EMKARATE RL 32-3MAF
Check oil level inside the compressor, where compressor’s oil level sight glass is available, after 30 min. of compressor running at
maximum capacity: oil level must be between 1/2 and 3/4 of sight glass. In tandem compressors, the oil level must be checked with both
compressors running at maximum capacity (note: when only one compressor is running, the oil level inside the compressor that is not currently
running could be at the minimum and the compressor, that is running, at the maximum capacity; when one compressor is running at maximum
capacity and one compressor is running in modulating capacity, the oil level in the latter one could be between 1/2 and the minimum).

(1) The recommended oil for units with R410A refrigerant is EMKARATE RL 32-3MAF.
(2) Unit coupled with remote condenser suggested for ambient temperature up to 35°C. With

(3) For distance D see Fig. 1 below.
(4) Topping up is requested for short pipeline too, due to the extra-charge of refrigerant.
