4. COMMISSIONING
26
4.4 XWPS section
To commission the XWPS section for the first time, the following actions have to be taken:
•
Check if the drop bridge between the two modules has been installed (see 3.3.1)
•
Check if the drain pipes have been installed correctly (see 3.3.2) and if the drip trays
inside the unit are clean.
•
Check that all loss parts/accessories have been removed from the inside of the unit.
•
Check the control panel if all the right set points are set in the controller (see separate
instruction manual controls)
4.4.1 Cooling circuit
When starting up the compressor of the cooling circuit for the first time it is very important to
check if the rotation direction of the compressor is correct!
Check this in the following way:
•
Start up the compressor and watch the HP gauge. If there is no pressure rise shown
on the HP gauge stop the compressor at once.
•
Change the two phases of the compressor on the terminal strip.
•
Start up the compressor again and check if the HP and LP gauge now are showing
reasonable temperatures.
•
Check the sight glass of the cooling circuit if there is enough refrigerant in the unit. If
refrigerant is missing stop the compressor at once and check for a leakage.
NB!
If the compressor runs with the wrong rotation direction for a longer time, this will damage
the compressor!
