Airjet
The residual air in the thermal carrier medium is collected
in the air jet [12] and can be vented manually by means
of the venting nipple [13]. To do this, attach the enclosed
hose to the nozzle of the venting nipple and collect the
escaping medium in a suitable vessel. Remove the hose
after venting.
Venting should only be performed by trained pro-
fessionals. Uncontrolled venting can lead to mal-
function of the solar system due to loss of pressure.
Caution! Risk of scalding!
The air and the thermal carrier medium escaping
while venting the system can reach temperatures of
over 100° C.
Afterwards, firmly close the nipple. Monitor the system
pressure while venting. If necessary, refill the solar sys-
tem with thermal carrier medium.
Controller / electrical connections
Note:
- Work on live parts must be carried out by an authorised
specialist!
- Fusing, wiring and earthing must be executed in accor-
dance with the local regulations.
- The electrical connection to the mains network must be
realised using the clamped power cable.
- The solar controller must be protected from surge dam-
age.
- The controller only needs to be opened for service work.
Ensure that the power supply has been disconnected
before opening the solar controller housing!
Pump cables, power cable and tank sensor are connected
to the solar controller ex-works. The collector sensor
must still be connected to the prepared extension.
Caution!
Do not severely bend or place the cable under tension!
Do not guide the cable over sharp edged components.
The cable must not come into contact with hot parts!
(For functional description and operation see separate
Controller Manual).
