8 - SYSTEM START-UP
All operations on the refrigerant circuit must be carried out in accordance with the applicable environmental
regulations.
After making the necessary electrical and hydraulic connections, carry out the system start-up and check the following steps:
-
Check the tightness of the electrical connections,
-
Check the hydraulic connections (direction of inlet/outlet connections),
-
Make sure the inside of the cabinet is clean and free of foreign bodies,
-
Check the electrical supply voltage and the ratings of the overload protections against the current ratings of each component,
-
Check the height of the trap,
-
Vent the air out of the coils via the bleed screws,
-
Check the circuits for any leaks; retighten the valve if necessary,
-
To configure the setpoints, refer to the "CCU Controller" manual
-
The air flow rate can be adjusted manually using the inverter
-
If a master/slave control system is used, make sure that the connection cable between the vertical units is in place.
-
Evacuate the system to obtain -0.1 M Pa (-760 mm Hg),
-
Fill with the required quantity of refrigerant fluid (for charges see the "Refrigerating circuit" section),
-
Simulate a trip of the electrical components, controlled instruments and alarms.
-
Check the current of each.
