12 - START-UP CHECKLIST FOR 30XW-VZE LIQUID CHILLERS (USE FOR

JOB FILE)

Unit start-up

Oil level is correct

All discharge and liquid line valves are open

Locate, repair and mark all refrigerant leaks

All suction valves are open, if used

All oil line valves and economizer valves (if used) are open

Checks have been carried out for any possible leaks. Unit has been leak checked (including fittings)

on the whole unit

at all connections

Locate, repair, and report any refrigerant leaks .............................................................................................................................

......................................................................................................................................................................................................

Check that control box is vented – Fan on electrical box must be on before compressor start-up and during operation.

Check voltage imbalance: AB ................ AC .................. BC ..................

Average voltage = ............................. V

Maximum deviation = ........................ V

Voltage imbalance = .......................... %

Voltage imbalance is less than 2%

WARNING: Operation of the chiller with an improper supply voltage or excessive phase imbalance constitutes abuse which will

invalidate the Carrier warranty. If the phase imbalance exceeds 2% for voltage, or 10% for current, contact your local electricity

supplier 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 temperatures below 0°C

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 SmartVu

Note all alarms: ....................................................................................................................................................................................

...............................................................................................................................................................................................................

Control IOM for the alarm menu).
