Warranty
Preface
Products tested and found to be in compliance with the requirements defined
in the EMC standards defined by 89/336/EEC as well as Low Voltage
Directive (LVD) 73/23/EEC can be identified by the CE Mark on the rear of
the unit. The testing has demonstrated compliance with the following directives:
LVD, 73/23/EEC Complies with IEC/EN61010-1
EMC, 89/336/EEC IEC/EN61326-1
For any additional information, refer to the Declaration of Conformity that
shipped with the unit.
Retain all cartons and packing material until the unit is operated and found to
be in good condition. If the unit shows external or internal damage contact
the transportation company and file a damage claim. Under ICC regulations,
this is your responsibility.
The Cole-Parmer circulators distributed by Cole-Parmer, Cole-Parmer
warrants to the direct purchaser that the product will be free from defects in
material or workmanship for a period of two years from the date of delivery.
Cole-Parmer will repair or replace the product or provide credit, as its sole
option, upon prompt notification and compliance with its instructions.
The Distributor warrants to Customer that upon prompt notification and
compliance with Distributor's instructions, that the Distributor will repair or
replace, at Distributor's sole option, any Product which is defective in material or workmanship.
Distributor expressly disclaims all other warranties, whether expressed,
implied or statutory, including the warranties of merchantability, and fitness
for a particular purpose. Distributor's sole responsibility and the Customer's
exclusive remedy for any claim arising out of the purchase of any Product is
repair or replacement, as described above. In no event shall Distributor's
liability exceed the purchase price pain therefor; nor shall Distributor be liable

Warnings
Safety
In addition to the safety warnings listed below, warnings are posted throughout
the manual. These warnings are designated by an exclamation mark inside an
equilateral triangle with text highlighted in bold print. Read and follow these
important instructions. Failure to observe these instructions can result in
permanent damage to the unit, significant property damage, personal injury or
death.
The lightning flash with arrow symbol, within an equilateral triangle, is
intended to alert the user to the presence of non-insulated "dangerous
voltage" within the unit's enclosure. The voltage may be of significant magnitude to constitute a risk of electrical shock.
This label, engraved into the front of the tank lip, indicates the presence of
hot surfaces.
Make sure you read and understand all instructions and safety precautions
listed in this manual before installing or operating your unit. If you have any
questions concerning the operation of your unit or the information in this
manual, contact our Sales Department.
Performance of installation, operation, or maintenance procedures
other than those described in this manual may result in a hazardous
situation and may void the manufacturer's warranty.
Transport the unit with care. Sudden jolts or drops can damage the
unit's components.
Observe all warning labels.
Never remove warning labels.
Never operate damaged or leaking equipment.
Never operate the unit without fluid in the circulator.
Use water unless operating above 80°C or below 7°C. Above 80°C use
Dow 200 silicon oil. For operation below 7°C, a 50/50 mixture, by volume, of filtered tap water and laboratory grade ethylene glycol is
suggested.
Always turn off the unit and disconnect the line cord from the power
source before performing any service or maintenance procedures, or
before moving the unit.
Always empty the circulator before moving the unit.
Never operate equipment with damaged line cords.
Refer service and repairs to a qualified technician.

Site
Installation
Never place the unit in a location where excessive heat, moisture, or
corrosive materials are present.
Locate the unit on a sturdy table or bench top.
Ambient Temperature Range +50°F to +89.6°F (+10°C to +32°C)
Relative Humidity Range 10% to 80% (non-condensing)
Operating Altitiude Sea Level to 2000 meters (6562 feet)
Overvoltage Category II
Pollution Degree 2
The unit has an air-cooled refrigeration system. Air is drawn through the front
panel and discharged through the rear panel. The unit must be positioned so
the air intake and discharge are not impeded. A minimum clearance of
12 inches (30 centimeters) at the front and rear of the unit is necessary for
adequate ventilation. Inadequate ventilation will reduce cooling capacity and,
in extreme cases, can cause compressor failure.
Excessively dusty areas should be avoided and a periodic cleaning schedule
should be instituted, see Cleaning on page 26.

Electrical
Requirements
Line voltage may be easily accessible inside the pump/control box.
Always unplug the unit prior to removing the pump/control box cover.
The unit construction provides protection against the risk of electric
shock by grounding appropriate metal parts. The protection may 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.
Refer to the serial number label on the rear of the unit to identify the specific
electrical requirements of your unit.
Ensure the voltage of the power source meets the specified voltage, ±10%.

Plumbing
Requirements
Ensure the unit is off before connecting tubing to the unit.
To prevent damage to the plumbing lines, always support the ¾"
fittings while installing/removing the pumping caps and lines.
Hose Connections
The pump connections are located at the rear of the pump box and are
labelled
capped with stainless steel serrated plugs.
The pump lines have ¼ inch male pipe threads for mating with standard
plumbing fittings. For your convenience two stainless steel adapters, ¼ inch
female pipe thread to 3/8 inch O.D. serrated fitting, are provided. (To ensure
proper fit, they should be installed using PTFE tape around the threads.)
Flexible tubing, if used, should be of heavy wall or reinforced construction.
Make sure all tubing connections are securely clamped. Avoid running
tubing near radiators, hot water pipes, etc. If substantial lengths of tubing
are necessary, insulation may be required to prevent loss of cooling capacity.
It is important to keep the distance between the unit and the external system
as short as possible, and to use the largest diameter tubing practical. Tubing
should be straight and without bends. If diameter reductions must be made,
make them at the inlet and outlet of the external system, not at the unit.
If substantial lengths of cooling lines are required, they should be pre-filled
with bath fluid before connecting them to the unit. This will ensure that a
adequate amount of fluid will be in the circulator once it is in operation.
(pump outlet) and (pump inlet). The connections are
Pumping
The pump is designed to deliver a flow of 15 liters/minute (4 gallons per
minute) at 0 feet head. To prevent external circulation, the INLET and
OUTLET lines are capped. The caps must be removed when external
circulation is required.
To properly secure the external hose connections to the unit, wrap PTFE
tape around the pipe line threads before installation. Once the hose connec-
tions are made, the pump must be properly plumbed to an external system. It
is important the circulator is not in operation until all plumbing is complete.
If
the circulator is not used for external circulation, make sure the stainless
steel caps are in place prior to operating the circulator.
