CAUTION:

 The chiller is specific to one input voltage. Supply only the 

proper input voltage, as labeled above the power terminals on the rear 
of the unit. Supplying the improper voltage can damage the unit and 
is not covered by the product warranty.

!

CAUTION:

 Always keep the chiller upright during operation. Additionally, 

THE UNIT MUST BE KEPT UPRIGHT FOR AT LEAST 24 HOURS 
BEFORE POWERING ON. This is to allow enough oil to reach the 
compressor. Powering-on the unit too early can permanently damage 
the compressor and is not covered by the product warranty.

!

CAUTION:

 

 This cooling system can chill liquid below the ambient air 

temperature, which may cause condensation to form on tubing and cold 
plates. It is highly recommended to keep the temperature at or above 
the ambient temperature. (See “TEMP SET” for details.)

!

CAUTION:

 Do not use a temperature set-point that is below the 

coolant’s freezing point. This may damage the cooling unit and is not 
covered by the product warranty. It is recommended to always keep 
the temperature set-point at or above ambient temperature.
