CyberRow unit is precharged with nitrogen at the end of manufacturing process. Check that the
stop valves of the air conditioner are closed when connecting refrigerant pipes.
1. Connect the pipes to the condenser. If the connections are pipes with brazed ends then cut the pipes, enlarge
them and braze them to the pipe. If the connections are threaded then flange the pipes and connect. Check which
is hot gas line and which is the liquid line.
2. Blow out the lines as follows:
• Plug the free ends of the pipes
• Connect a cylinder of dry nitrogen equipped with a pressure reducer (maximum pressure 10 bar) to the Schrader
fittings on the condenser.
• Pressurize the pipes with dry nitrogen
• Instantly unplug the pipes
• Repeat this process several times
3. Weld the pipes to the fittings on the air conditioner. For pipe passage, use the openings either on the base or on
the top of the unit.
Only for CyberRow size 1: electric box of the unit can rotate on its side for a better accessibility
during maintenance. Lay out pipes inside the unit so that they do not impede its free movement.
Refrigerant at high pressure and temperature might go out from the discharge point of safety valve.
Danger in the proximity of the discharge point.
• In case of any leakage, after finding and repairing the leak, repeat the check.
After checking the pipe seal open the conditioner and condenser cocks and proceed with the next installation phase
(creation of a vacuum and filling the circuit).
