13 - START-UP CHECKLIST FOR LX LIQUID CHILLERS (USE FOR JOB FILE)
Unit start-up
a. The oil heaters have been powered up for at least 24 hours.
b. Oil level is correct
c. All discharge and liquid valves are open
d. All suction valves are open, if equipped
e. All the oil line valves and economiser ball valves (if installed) are open.
f. The contactor
g. Checks have been carried out for any possible leaks. Unit has been leak checked (including fittings)
g1 - on the whole unit
g2 - at all connections
Locate, repair, and report any refrigerant leaks ................................................................................................................................................................................
..........................................................................................................................................................................................................................................................
..........................................................................................................................................................................................................................................................
h. Check voltage imbalance: AB ................................... AC ........................... BC ..............................
Average voltage = .............................................. V
Maximum deviation = ......................................... V
Voltage imbalance = .......................................... %
i. Voltage imbalance less than 2 %
WARNING: operating the chiller with an incorrect supply voltage or excessive phase imbalance constitutes improper use and will invalidate the CIAT warranty. If the
phase imbalance exceeds 2% for voltage, or 10% for current, contact your local electricity supply at once and ensure that the chiller is not switched on until corrective
measures have been taken.
Check cooler water loop
Water loop volume = ............................................... litres
Calculated volume = ............................................... litres
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 ...............................
Piping includes electric heater tape, if exposed to the outside
Inlet piping to cooler includes a 20 mesh strainer with a mesh size of 1.2 mm
Check pressure drop across the cooler
Entering cooler = ..................................................... kPa
Leaving cooler = ...................................................... kPa
Leaving - entering = ................................................ kPa
WARNING: Plot cooler pressure drop on performance data chart (in product data literature) to determine total litres per second (l/s) and find unit’s minimum flow rate.
Total = ...................................................................... l/s
Nominal kW = .......................................................... l/s
Total l/s is greater than unit’s minimum flow rate
Total l/s meets job specified requirement of
.................................................................................. l/s
WARNING: Once power is supplied to the unit, check for any alarms. Refer to the POWERCIAT Connect’Touch control manual for the menu of alarms.
Note all alarms: ...........................................................................................................................................................................................................................................
