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.

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.

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.

The pipet outlet on the back panel is a 3/8” 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.
