7.6 Filling, venting and degassing
Your Integral XT has no bath which actively takes part in the temperature stabilization. There is however
an expansion vessel which is filled with the liquid. The liquid passes to the external loads via the internal
piping and the connected hoses.
+ −
The devices are rated for use with non-flammable and flammable liquids according
to DIN EN 61010-2-010. The temperature in the expansion tank must not rise
more than 25 °C below the flash point (
þ
1.2).
−
With the use of heat transfer oils note that they expand on heating (approx.
10%/ 100 K).
−
Set the lower and upper temperature limits (
þ
7.10.2) such that the limits for the
heat transfer liquid are not infringed.
+ −
Close the drain taps.
1 tap for XT 150, XT 250W ... up to max.
4 taps with XT 750 H and larger.
−
Check whether the sealing caps on the
drains (1 to 4 depending on the thermo-
stat) are tight. Tighten only slightly with an
open-ended wrench (AF19).
−
Before filling, remove all the residue of the
previous liquid (
þ
7.8).
7.6.1
Filling
−
Switch on the thermostat.
−
The filling with the filling program starts automatically if a low level
is found when the device is switched on.
−
With Tmax enter the maximum permissible liquid temperature
(
þ
7.16.1).
−
Start filling. When Level 1 is reached, the display changes to
F
and shows the corresponding level indication.
−
Minimum device filling volume (
þ
11).
−
Alternatively, watch the level indication as displayed on both, the
Master or Command control head.
+ −
Fill the heat transfer liquid at room temperature up to Level 4.
−
Only operate the thermostat when flow in the load system is possible. Open
any shut-off taps in the load.
−
During filling, the device can overflow if the load is located higher than the de-
vice and the filling is interrupted (e.g. mains failure). There may still be large
quantities of air in the load which allows a return flow of the filled liquid. In case
of doubt a shut-off tap should be fitted on the lower load connection.
