6510 Water Handling System Operating Instruction Manual
- 5 -
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.
