Cautions/Warnings
1. Power (ALWAYS check the Chiller Parameter tag and verify operational voltage before plugging in chiller)
a. Only connect North Slope Chillers to a properly grounded circuit
b. Never connect your North Slope Chiller to voltage that is outside the acceptable voltage range.
Connecting your chiller to any voltage outside of these ranges will damage the compressor.
i. 110V model will operate on voltages between 100 ~ 130V
ii. 230V model will operate on voltages between 200 ~ 250V
c. Only use power sources that are 60Hz, running the chiller at 50Hz will void the warranty and will
damage the compressor
2. Never run the pump dry, only turn on chiller after the fluid reservoir has been filled. Running the chiller without
fluid will permanently damage the pump and void the warranty
3. This chiller is air cooled and must have good ventilation. For proper function there must be a minimum of 1 foot
clearance on both sides and 2 foot clearance at the back of the chiller
