1564 Water Recirculation System Operating Instruction Manual
- 4 -
Description
The system consists of a 1.5 gallon reservoir to receive the overflow from the 6300
Calorimeter, a recirculation pump, and a power supply. As the calorimeter flushes and
cools the bomb, the overflow water drains freely into the reservoir. The recirculation
pump then pumps water back to the calorimeter on demand.
Required Accessories and Utilities
A separate water cooler must be used with the 1564 system to remove the heat
introduced by each calorimeter test. A Parr 1552 Water Cooler is recommended for this
purpose. The cooler must be placed between the 1564 system and the 6300
Calorimeter. The circulating pump in the 1564 system provides enough pressure for
both the cooler and the calorimeter.
Approximately 4 L of water with a total hardness of less than 85 ppm is required for
filling the tank of the system.
Installation
Install the 1564 system below and near the calorimeter so that the cooling and overflow
water can drain freely from the calorimeter. This instrument is to be used indoors and
requires 3 square feet of space below the calorimeter in a well-ventilated area with
convenient access to an electric outlet. The supply voltage must be within ± 10% of
marked nominal voltage on the instrument. The supply voltage receptacle must have an
earth ground connection.
The water cooler can be installed in any convenient location however care should be
taken that heat from the compressor not reach the calorimeter. Additionally, air must be
allowed to move freely from the cooling fan into the cooler.
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.
Connect the A1336DD drain tube assembly from the 412VB union bulkhead, labeled
Drain, on the back panel of the calorimeter to the 271HWHJ hose barb on the top of the
1564 Water Recirculation System. The A1336DD drain tube assembly is supplied in the
A1267DD accessory and installation kit of the 6300.
Connect the supplied ¼” tubing from the female connector (P/N 526VBAD) labeled
“Water Outlet” on the back panel of the Water Recirculation System to the union elbow
(P/N 496VB) labeled “Water In” on the top of the water cooler.
Connect the supplied ¼” tubing from the union elbow (P/N 496VB) labeled “Water Out”
on the top of the water cooler to the female connector (P/N 477VB) labeled “Water” on
the back panel of the calorimeter.
