5. Make sure that there are no open flames or other heat sources (such as electrical switches, etc.) close to the cabinet.
And do not smoke!
6. Open the refrigeration circuit on the ad-hoc gas-charging pipe by removing the cap attached to the end. If necessary
retrieve the R290 gas with proper equipment.
7. Before using any flame, fill the circuit of nitrogen in order to eliminate any R290 gas residues.
8. Empty the nitrogen from the circuit. Start repairs by replacing the faulty parts, (replace the drier filter if necessary).
9. Once repairs have been completed, make the vacuum in the refrigerant circuit through the charging pipe, using the
appropriate throttle valve or the "Schrader" adaptor previously welded to the end.*(See note).
10. After the vacuum phase has been completed, start charging the gas entering 50% of the quantity of R290 gas
indicated on the rating plate applied on the cabinet. Connect its electrical plug to the power supply socket.
11. Turn on the power on the cabinet (see par.6), wait for compressor's start-up, and then complete unit charging with
remaining 50% quantity of R290 gas.
12. Verify the correct cabinet operations.
13. With the cabinet running, seal the end of the charging pipe with an ad-hoc cap available in the tools set. With a proper
tool clamp the charging pipe 2 times, about 2-3 cm distant from each other, just behind the cap.
14. Turn off the cabinet and check the tightness of the refrigeration circuit with a leak detector calibrated to detect the
R290 gas.
* N.B.- The opening of the refrigeration circuit has to be done from the gas charging pipe, after the charge the
circuit MUST be tightly closed by sealing the charging pipe. In case of need you can weld a "Schrader" adaptor to
perform vacuum operations and refrigeration circuit filling. Once the R290 gas filling has been completed, clamp the
charging pipe with the proper tool, just behind "Schrader" adaptor, at least 2 times, at about 2-3 cm distant from each
other.
