4.
Screw a hose onto the drain nozzle (3/8" a). There are three drain
nozzles on the Integral XT with through-flow control.
As far as possible, the following sequence is recommended:
- Constant temperature equipment of expansion vessel
- Flow controller
- Constant temperature equipment of hydraulic circuit
See
Chapter 3.1 “Overall view of Integral (large casing
5.
Place the hose in a suitable container to collect the heat transfer
liquid.
It may be necessary to drain the device several times if the
filling volume is high.
6.
Open the drain tap or taps. To do this, turn the tap counterclockwise.
7.
Allow the device to run empty.
8.
After the device has run empty remove the hoses from the external
consumers. Drain the heat transfer liquid in the hoses into a suitable
container.
9.
After draining close the drain tap or taps.
Observe the regulations for the disposal of used heat transfer liquid.
After the heat transfer liquid has been drained, residues remain in the device.
These residues must be removed to avoid deposits in the device during
storage.
If new heat transfer liquid is added and the device is operated above the
thermal load limit for the old heat transfer liquid, deposits can form, espe-
cially on the heaters. These coatings reduce the performance of the device
and/or reduce the service life of the device.
