Operation and control<br />
5. Operation and control<br />
5.1 Operating staff<br />
The test chamber may only be operated by persons who are of legal age, and who have received<br />
instructions for the test chamber. Personnel who are to be instructed or who are undergoing<br />
general training may only work with the test chamber under the continuous supervision<br />
of an experienced person.<br />
5.2 General information on operation<br />
The condensation pressure of the cooling unit is controlled by the automatic speed adjustment<br />
of the condenser fan. The fan can therefore automatically run faster or slower in operation,<br />
depending on the thermal energy extracted. The speed of the interior fan can also vary:<br />
At low temperatures the fan speed is automatically reduced. In strong heating operation it is<br />
automatically increased.<br />
5.3 Before starting<br />
1. Empty the condensation water tank. To do<br />
so, pull out the tank drawer from the test<br />
chamber (for CTC climatic test chambers,<br />
see Fig. 15) or open the flap (for TTC<br />
temperature test chambers).<br />
2. Screw open the lids of the condensation<br />
water tanks A1 and A2, remove tanks,<br />
empty and then re-insert them and screw<br />
the lids back on.<br />
Caution:<br />
Do not mix up the lids, otherwise condensation<br />
water may leak. Screw on the lid<br />
with the T-connector onto the tank at the<br />
rear (A1) (Fig. 15), so that condensation<br />
water can flow into tank A2 when tank<br />
A1 is full.<br />
3. For the climatic test chambers CTC, fill<br />
the two fresh water tanks (B1 and B2) as<br />
described on page 22.<br />
4. Check whether the silicone plugs have<br />
been inserted into the feed-through on<br />
the right side of the appliance and if the<br />
seal is tight (see Fig. 17 on page 26 ).<br />
