7 COMMISSIONING
7.1 Preliminary operations
Make sure the main disconnect switch is in the OFF position.
Before filling the hydraulic system, check that the drain valve is closed and that all the air valves are open.
Open the shut-off devices of the system and start to fill it by slowly opening the water filling valve.
When water begins to come out through the air valves, close them and continue filling until the pressure value envisaged
for the system is reached.
The unit should only be started up by qualified personnel authorised by the manufacturer.
All the units are pre-charged with refrigerant gas, so the refrigerant circuit is pressurised.
Check:
- that the electrical connection has been made correctly and that all terminals are properly tightened;
-
that the voltage on the RST terminals is 400 V ± 10% (or the rated voltage of the unit if there are special voltages). If the
voltage fluctuates frequently, contact our technical department to choose suitable protective devices;
-
that the gas pressure in the refrigerant circuits is shown on the pressure gauges (if present) or on the control display;
-
that there are no refrigerant fluid leaks, using a leak detector, if necessary (the presence of oil stains may be a sign of
refrigerant leaks);
Be careful with the electrical checks and use only suitable tools.
Position the master switch of the unit to ON and check on the display of the control that the unit is OFF in order to prevent
it from starting.
Check that the crankcase heaters are powered correctly.
