Check voltage imbalance: AB ................ AC ................. BC..................
Average voltage = .................................................... (see installation instructions)
Maximum deviation = ............................................. (see installation instructions)
Voltage imbalance = ................................................ (see installation instructions)
Voltage imbalance is less than 2%
WARNING: Do not start chiller if voltage imbalance is greater than 2%. Contact your local power company for assistance.
All incoming power voltage is within nominal voltage range
The compressor crankcase heaters have been running for 6 hours
Check evaporator water loop
Water loop volume = ................... (litres)
Calculated volume = ................... (litres)
Proper loop volume established
Proper loop corrosion inhibitor included .....................................litres of ............................
Proper loop freeze protection included (if required) ................. litres of .............................
Water pipes have been tted with trace heating up to the evaporator
Return water piping is equipped with a screen lter with a mesh size of 1.2 mm
Check pressure drop on the evaporator (without hydraulic module) or ESP* (with hydraulic module)
Entering evaporator = ................................................................ (kPa)
Leaving evaporator = ................................................................. (kPa)
Pressure drop (Inlet - Outlet) = ................................................ (kPa)
* ESP : External Static Pressure
WARNING: plot the pressure drop on the evaporator ow/pressure drop curve to determine the ow rate in l/s at the
nominal operating conditions for the system. For units with hydraulic module, an indication of the ow is displayed by the
unit control device (see the 30RBM/30RBP control manual).
If necessary use the control valve to adjust the ow rate to the desired value.
Flow rate from the pressure drop curve, l/s = ..................................................
Nominal ow rate, l/s = ......................................................................................
The ow rate in l/s is higher than the minimum unit ow rate
The ow rate in l/s corresponds to the specication of ............................(l/s)
