15 - UNIT START-UP CHECKLIST FOR INSTALLERS PRIOR TO
CONTACTING THE MANUFACTURER
Unit start-up
Chilled water pump contactor has been correctly cabled with the chiller
The oil level is correct
The unit has been checked for leaks (including couplings)
Locate, repair, and report any refrigerant leaks

Check voltage imbalance: AB................
Average voltage = ......................... (See installation instructions)
Maximum deviation = .........................
Voltage imbalance = ......................... (See installation instructions)
Voltage imbalance is less than 2%
WARNING
Do not start the chiller if the voltage imbalance is greater than 2%. Contact your local power company for assistance.
All incoming power voltage is within the nominal voltage range
The compressor crankcase heaters have been running for 6 hours
Evaporator water loop check
Water loop volume ................... = ................... (litres)
Calculated volume ................... = ................... (litres)
Correct loop volume established
Correct loop corrosion inhibitor included ....... litres of
Correct loop frost protection included (if required)
Water piping includes electric tape heater up to the evaporator
Return water piping is equipped with a screen filter with a mesh size of 1.2 mm
Checking the pressure drop across the evaporator (without hydraulic module) or ESP
Evaporator inlet = ................................... (kPa)
Evaporator outlet = ................................... (kPa)
Pressure drop (Inlet - Outlet) = .............. (kPa)
(1) ESP: External Static Pressure
WARNING
Plot the pressure drop on the evaporator flow rate/pressure drop curve to determine the flow rate in l/s at the nominal operating
conditions for the system. For units with hydraulic module, an indication of the flow rate is displayed by the unit control
device (see the 30RB/30RQ control manual).
If necessary, use the control valve to adjust the flow rate to the rated value.
Flow rate from the pressure drop curve, l/s = .......................................
Nominal flow rate, l/s = .................................
The flow rate in l/s is higher than the minimum unit flow rate
The flow rate in l/s corresponds to the specification of ......................... (l/s)
