Applications

This owner’s manual is to be used for the following North Slope Chillers:

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

4. Flush chiller prior to use. North Slope Chillers tests every chiller on site prior to shipping. During testing North

Slope Chillers uses a water/glycol mix to test their chillers. There will always be a small amount of water/glycol
remaining in the system. Since not all glycols are compatible with each other and vary by manufacture each
chiller should be flushed with water for 10 minutes prior to use.

Specification sheet

North Slope Chillers tests every chiller on site prior to shipping. During testing North Slope Chillers uses a water/glycol
mix to test their chillers. Since not all glycols are compatible with each other and vary by manufacture each chiller
should be flushed with water for 10 minutes prior to use.

*The mix of Glycol to Water should be proportional to the desired freeze point. Always select a Glycol/Water mix that
will prevent freezing at 25F below your set point. This will prevent freezing from occurring in the heat exchanger and
prevent damaging the system. For example if your setpoint is 10F you should select a glycol percentage that would
prevent freezing at -15F.
