Discharge Of The Safety Valves; Emergency Stop - Swegon BlueBox Omega Sky Installation, Use And Maintenance Manual

In units with capacitors and/or inverters, certain components can remain live for several minutes even after
having turned off the main switch.
Wait 10 minutes before working on the electrical parts of the unit.
Circuits supplied from external sources (made with orange cable) can remain live even after the power sup-
ply to the unit has been turned off.
Work on the unit only if there is sufficient lighting for the type of work to be carried out.
Failure to comply with the instructions in this manual and any modifications made to the unit without prior written consent,
will immediately void the warranty.
The law regulating the use of stratospheric ozone depleting substances prohibits the release of refrigerant
gases into the environment and obliges owners to recover and return them to the dealer or take them to spe-
cial collection centres at the end of their operational life.
The refrigerant contained in the refrigerant circuit is included among the substances subject to special con-
trol regulations provided for by law and must therefore be disposed of as indicated above.
Particular care should be taken during maintenance operations in order to reduce refrigerant leaks as much
as possible.
2.1.1

Discharge of the safety valves

If present on the refrigerant circuit, installation requirements and/or national regulations lay down that the discharge of the
safety valves must be routed to the outside.
The conveying must be done with a pipe whose diameter must be at least that of the valve outlet, and the weight of the pipe
must not be borne by the valve.
Always direct the discharge to areas where the jet cannot cause harm to anyone.
Risk of burns following contact with hot and cold parts.
2.1.2

Emergency stop

In case of emergency, an immediate stop is carried out using the red disconnecting switch/master switch on the electrical
control panel by turning it to 0. When it is turned to 0, the disconnecting switch turns off the power to the whole unit.
The main disconnect switch/master switch, used to electrically isolate the unit, is also intended for use as an
emergency device and it is only in an emergency that it should be used to stop the unit.
Unless there is an emergency condition, the operation of the unit must be stopped using the displayed con-
trols "control or external OK signal".
