Operating Instructions
For the 6510 Water Handling System
Purpose
The 6510 Water Handling System acts as a cooling and circulating water source for
maintaining a constant jacket temperature in the 6200 Isoperibol Calorimeter. It also
provides a convenient and consistent means for filling the bucket in a Parr 6200 or 6100
Compensated Jacket Calorimeter. Either one or two 6200 Calorimeters can be served
from a single 6510 System.

Safety Information
To avoid electrical shock, always:
1. Use a properly grounded electrical outlet of correct voltage and current handling
capability.
2. Ensure that the equipment is connected to electrical service according to local
national electrical codes. Failure to properly connect may create a fire or shock
hazard.
3. For continued protection against possible hazard, replace fuses with same type
and rating of fuse.
4. Disconnect from the power supply before maintenance or servicing.
To avoid personal injury:
1. Do not use in the presence of flammable or combustible materials; fire or
explosion may result. This device contains components which may ignite such
material.
2. Refer servicing to qualified personnel.
Intended Usage
If the instrument is used in a manner not specified by Parr Instrument Company, the
protection provided by the equipment may be impaired.

Before connecting the water handling system to an electrical outlet, the user must be
certain that the electrical outlet has an earth ground connection and that the line, load
and other characteristics of the installation do not exceed the following limits:
Voltage: Fluctuations in the line voltage should not exceed 10% of the rated nominal
voltage shown on the data plate.
Frequency: Water handling systems can be operated from either a 50 or 60 Hertz
power supply without affecting their operation or calibration.
Current: The total current drawn should not exceed the rating shown on the data plate
on the water handling system by more than 10 percent.
Environmental Conditions
Operating: 15 ºC to 30 ºC; maximum relative humidity of 80% non-condensing.
Installation Category II (overvoltage) in accordance with IEC 664.
Pollution degree 2 in accordance with IEC 664.
Altitude Limit: 2,000 meters.
Storage: -25 ºC and 65 ºC; 10% to 85% relative humidity.

6510 Water Handling System Operating Instruction Manual
Description
The system consists of a 20 liter, temperature controlled, tank with a built in circulating
pump, an attached glass delivery pipet and provision for continuous filtration of all water
in the system. This is a closed circuit system in which water is re-used continuously.
When the 6510 System is used with a 6200 Calorimeter, water from the tank is
delivered to the temperature control manifold at the rear of the calorimeter and returned
in a closed loop, thereby maintaining a constant temperature in the calorimeter.
The water handling system can be used to supply water not only to the calorimeter
jacket but also to the bucket through an attached delivery pipet. The choice of oxygen
bomb size will dictate the pipet choice as follows:
Oxygen Bomb Pipet Volume Pipet Part Number Support Assembly
1108 2000 mL 167HW A335HW
1104 1850 mL 167HW2 A335HW
1109 450 mL 167HW3 A335HW2
A maximum of two pipets may be installed on the water handler. Only one pipet may be
filling the bucket at any one time.
Temperature controlled water flows continuously through the glass delivery pipet and
back to the tank to maintain a constant water temperature in the pipet for filling the
calorimeter bucket with repeatable volumes. Flow through the pipet stops when the
stopcock is opened to fill the calorimeter bucket. The pipet refills automatically when
the stopcock is turned back to a closed position. At the end of each test, the user will
empty the bucket water into the reservoir where it is released slowly into the tank so as
not to cause a sudden change in temperature.
NOTE: Do not leave the stopcock dry as the Teflon will seize in the glass.
Incorporated in the system is a solid-state water chiller that is capable of removing and
dissipating the heat in the returned bucket water produced during calorimetric testing,
thus maintaining the water at a constant temperature for repeatable test temperatures.
Required Accessories and Utilities
Approximately 15 L of water with a total hardness of less than 85 ppm is required for
filling the tank of the system.

6510 Water Handling System Operating Instruction Manual
Installation
Install the 6510 System near the calorimeter so that the water connections are kept
short. The water system can be installed in any convenient location however care
should be taken that heat from the compressor on the left side of the Water Handling
System not reach the calorimeter. Additionally, air must be allowed to move freely
around the cooling fan on the back of the 6510 System. The supply voltage must be
within ± 10% of marked nominal voltage on the instrument. The supply voltage
receptacle must have an earth ground connection.
Make the tubing connections as illustrated in Figure-1.
Note: It is critical to keep the tubing between the calorimeter and the water
system as short as possible and eliminate any uphill runs or kinks. This
will impede the free flow of water from the calorimeter.
Pipet Installation
The A335HW pipet support brackets can be installed on either side of the water
handling system. There are four mounting screws (TA1632PP06) located on each side
of the water handler. The pipet is installed by slightly tilting and inserting the round top
portion of the pipet into the hole in the pipet support. The lower support bracket holds
the pipet from underneath by inserting the pipet into the slotted end of the bracket.
Insert the 148C, 3-way PTFE stopcock plug into the pipet and secure it using only
enough tension on the spring loaded retaining nut to prevent leakage. Insert the short
3
/8” OD Nylon tube into a three-inch length of black latex tubing furnished with the
system. Attach the tubing to the discharge tube that extends downward from the
stopcock. This provides a flexible tip to prevent breakage if the bucket were to strike
the discharge tube during the filling operation. Extending the discharge tube into the
bucket also minimizes splashing of the water while the bucket is filling.
3
The pipet outlet on the back panel is a
/8” tube connection. A 219HW barb connector is
provided to install the JR0056TB125A tubing. Install a 6” piece of JR0056TB125A
tubing on the barb connector. Install the 149C in-line filter; make sure the arrow on the
filter is pointing towards the pipet. Install JR0056TB125A tubing from the 149C filter to
the bottom port of the pipet. The pipet return on the back panel is a ½” tube connection.
A 309HW barb connector is provided to install the JR0056TB125A tubing. Install tubing
from the 309HW barb connector to the top port on the pipet.
Note: It is critical to keep the tubing from the pipet to the water handler as
short as possible. Any extra tubing can create a downward loop in the tube
and potentially back up the water, restricting the flow.
