Temperature Control Units
Installation
The temperature control unit is connected to the bath and cir-
culator placed at disposal (not shown in the picture). The cir-
culator should be equipped with a pressure and suction
pump. Connection OUT/IN 14
!
While fastening the hose connections at the con-
necting nozzles(14) of the temperature control
unit::
- - ensure the correct flow direction (IN/OUT)
- - the connecting nozzles must be held secured
using a wrench.

For the cooling of the temperature control unit hoses (with

 8mm) can be connected to a liquid circulator.
maximum conduction pressure 0.5bar (water circulation).
For the SHRP sensor system and the bath and circulator the
15
required hoses are no standard accessories. They must be
ordered separately.

The ball valve (accessories) is placed at the outlet port of the
bath and circulator. The valve setting is done by means of a
screwdriver to regulate the rate of flow of the bath liquid so
that the liquid level in cup vessel 6 can ascend to the upper
circular ring but not above. When connecting the circulator
first time to the SHRP unit the ball valve must be in the
"closed position" to prevent a sudden overflow in cup vessel
6. The ball valve should be gradually opened to adjust the
proper flow rate. In this phase of the installation valve 8 is
maintained in the open-valve position. For placing new sam-
ple disks into the gap between the parallel plates and for the
removal of these samples at the end of a test, the liquid level
in the cup vessel 6 can be lowered by closing the valve 8: the
liquid in 6 is sucked back to the circulator via hose 11 and cup
vessel 6 is emptied. The inflow and flowing off of the bath liq-
uid is only controlled by valve 8.
Liquids that flow over the cup vessel during the measure-
ment are collected in the underside of the housing and are
led back to the bath and circulator via overflow 16 (for hose
 8mm).
