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 cooler water loop
Water loop volume = .............................. (litres)
Calculated volume = ............................... (litres)
3.5 liters/nominal kW capacity for air conditioning (units 30RW/30RWA 020-045)
2.5 liters/nominal kW capacity for air conditioning (units 30RW/30RWA 060-300)
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 (unit without pump)
Check pressure drop across the evaporator
Entering evaporator = ............................ (kPa)
Leaving evaporator = ............................. (kPa)
(Leaving - entering) = ............................ (kPa)
WARNINg: Plot cooler pressure drop on performance data chart (in product data literature) to determine total liters
per second (l/s) and find unit’s minimum flow rate.
Total l/s = .................................................
l/s / nominal kW = ...................................
Total l/s is greater than unit’s minimum flow rate
Total l/s meets job specified requirement of ...................................... (l/s)
