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
Compressor crankcase heaters have been activated 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 piping includes electric tape heater 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 hydronic module) or ESP* (with hydronic 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 hydronic 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)
