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 local power company for assistance.
All incoming power voltage is within rated voltage range
Check evaporator water loop
Water loop volume
Calculated volume
3.25 litres/nominal kW capacity for air conditioning
6.5 litres/nominal kW capacity for process cooling
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 filter with a mesh size of 1.2 mm
Check pressure drop across the evaporator
Entering evaporator = ............................ (kPa)
Leaving evaporator = ............................. (kPa)
Pressure drop (entering - leaving) = ..... (kPa)
WARNINg: Plot the pressure drop on the evaporator flow/pressure drop curve to determine the flow rate in l/s at the
nominal operating conditions for the installation.
If necessary use the control valve to impose the flow rate on the nominal 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)
= ................... (litres)
= ................... (litres)
