Polystat 3-1
Cole Parmer
Section 3
Installation
The desk-top chiller is designed for continuous operation and for indoor use.
Never place the chiller in a location where excessive heat, moisture,
inadequate ventilation, or corrosive materials are present.
NOTE
Refer to the nameplate information on the rear of the chiller.
Chillers retain their full rated capacity at 20°C setpoint in ambient
temperatures up to 25°C (77°F). For ambient temperatures above 25°C
please de-rate the cooling capacity 3% for every 1°C above 25°C (77°F), up
to a maximum ambient temperature of 35°C (95°F). Please note that when
operating at a process temperature lower than 20°C the de-rate percentage
may increase due to additional losses to ambient.
NOTE
Depending on the setpoint and ambient temperatures, there may be
a heat gain or loss through the plumbing resulting in a variation from setpoint
temperature at the application inlet. Applications with large temperature
variations between ambient and setpoint temperatures, and/or long plumbing
lengths, may require additional insulation.
The front of the chiller needs a minimum clearance of 24". The rear and
sides should also be clear of obstructions. Air will enter the front of the
system and exit through the sides and rear.

CAUTION
Electrical
Requirements
The chiller construction provides protection against the risk of
electrical shock by grounding appropriate metal parts. The protection
will not function unless the power cord is connected to a properly
grounded outlet. It is the user's responsibility to assure a proper
ground connection is provided.
Locate the chiller so it is near, and has easy access to, its disconnecting
device.
The user is responsible to ensure that the line cord provided meets local
electrical codes. If not, contact qualified installation personnel.
The chiller is intended for use on a dedicated outlet. The Polystat has an
internal circuit protection that is equivalent (approximately) to the branch
circuit rating. This is to protect the Polystat, and is not intended as a
substitute for branch circuit protection.
