Fig. 3-13 Connection of flexible hoses in the internal unit
Connect the thermistor cable to the switch box in the
internal unit. Make sure that the power supply is switched
off. See the electrical circuit diagram supplied with the
internal unit for this.
The distance between the thermistor cable and the mains
cable must always be at least 50 mm, so that the thermistor
cable is not subjected to any electromagnetic interference.
Plug the connector on the thermistor cable into socket X11A
on the PCB.
For strain relief, fasten the cable to the corresponding anchor
points with cable ties.
When laying the cables, take care that the cables do not
obstruct the attachment of the internal unit covers.
Note: Only the relevant on-site cabling is shown.
Insert the thermistor to a depth of 80 cm in the probe tube
(see EKSRPS3 operating and installation instructions).
