Warnings
Section I Safety
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 (see After-sale Support).
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.
Observe all warning labels.
Never remove warning labels.
Never operate damaged or leaking equipment.
Never operate the unit without cooling fluid in the reservoir.
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 reservoir before moving the unit.
Never operate equipment with damaged line cords.
Refer service and repairs to a qualified technician.
In addition to the safety warnings listed above, 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 instruction
can result in permanent damage to the unit, significant property damage, or
personal injury or death.

Facility Water
Requirements
Section III Installation
The unit should be placed in a laboratory or clean industrial environment with
easy access to a facility cooling water and a drain.
Limit the facility water inlet pressure to less than 150 psi (10,2 Bar) and
limit the facility water inlet pressure to outlet pressure differential
across the System IV to less than 35 psid (2,4 Bar).
Refer to the Cooling Capacity chart in Section II, Specifications. The flow rate
of the cooling water supply must meet or exceed these requirements for the
unit to operate at its full rated capacity. If the cooling water does meet these
standards, the cooling capacity will be derated. The chart is based on a 10°C
difference between the temperature of the cooling water supply and the process fluid entering the instrument being cooled.
As the heat load increases, the required flow rate of the cooling water supply
increases. For example, if the heat load is 60 kilowatts, only 20 gallons per
minute is required to remove the heat. However, if the heat load is 80
kilowatts, 26 gallons per minute is required.
The flow meter on the front of the unit does not measure the flow rate of the
cooling water supply. The flow meter measures the flow rate of the cooling
fluid returning to the instrument being cooled.

on the graph below.
