STARTING UP
STARTING UP FOR THE FIRST TIME
Installation:
•
Attention: the unit is filled with HFC R407C refrigerant.
This refrigerant belongs to group I ( no toxic - no
dangerous) according to EN Norm 378 and according
the specification contained into CEE law n° 2037/00.
•
Install the unit in the computer room. Make sure that
the air inlet grilles have more than 0,3 m free space
around. [ left - right side ]
•
The condensate discharge lines can suitably pass in
pre-sheared holes on the unit basament.
Electrical connections:
•
Open electrical panel.
•
Disconnect the main switch.
•
Inlet cables holes are positioned on the bottom side
of the unit
•
Connect the power supply and the earth connection
to the main switch and to the main earth connection.
•
3 phase versions only. In case of wrong phase
sequence, the compressor will start in the opposite
direction: scroll compressors have to turn in one only
direction. The phase sequence relay is connected in
series with the air flow switch, so that if wrong R-S-T
occurs an “FL” alarm on mP will appear. In this case
disconnect the power supply, reverse two phases
before the main switch and restart. NB: the R-S-T
phase sequence device is positioned in the left part
of the E-Panel: green light means power presence
and the yellow light means correct phase sequence;
if the yellow light doesn’t shine, switch of the main
switch and reverse two cables before the main switch.
•
Close the panel.
•
Press button “ON” on the microprocessor keyboard.
Start Up
•
Make sure that the air flows normally and the flow
switch alarm is not present.
•
Press the “ON” button on the mP keyboard:
o
The indoor fan will start immediately
o
After 20 second and if no alarm are
present, the compressor will start up. NB:
the compressor will start if the indoor
conditions are according the set point
presetted in the mP.
•
Check the air Delta T: it has to be between 7 and
10 °C.
•
Check for refrigerant leakage.
Operation
•
Use the microprocessor and the unit manuals
