Nameplate Information
All important information for identication of the compressor is printed on the nameplate located below the compressor oil pump.
The type of refrigerant used should be stamped on the nameplate by the installer.
The date of production indicates the year and week of production. The year and month of production are also part of the serial number
(Jan. = A, Feb. = B, ... Dec. = L).

IMPORTANT
It is essential that the glide of refrigerant blends (primarily R407C) is carefully considered when adjusting pressure and
superheat controls.

Table 2: Qualied refrigerants and oils for recharging and topping up
To Recharge:
When the compressor is completely empty of oil, the amount of oil to be “recharged” is typically 0.12 litre less than the original oil
charge (oil will already be around the system).
To Top up:
During commissioning, planned maintenance or servicing, add oil so that the compressor oil level is correct.
