4.1 Start-up and operating instructions
The Windhager Customer Service or Partner Customer Service will start up the boiler and will familiarize the
customer with the system operator and cleaning of the boiler. Start-up and maintenance are part of the guarantee
requirements of the “warranty conditions” – see also section 1.4.
We recommend that you obtain a maintenance service contract.
4.2 Service and repair work
Service and repair may be performed only by appropriately qualified technicians.
Attention!
De-energise the boiler before opening the control panel for service or repair purposes. Unplug power plug – Fig. 79.
Switching off the on/off button on the InfoWINplus does not mean the boiler and its accessories are completely
without power! When replacing system components (pumps, mixing valves, etc.) prevent all power input (e.g. by
removing the mains power plug).

4.3 Checking and servicing the thermal process safeguard
(Please inform your customer)
Attention!
The function of the thermal process safeguard must be checked once a year by a technician and the
amount of limescale in the thermal safety device must be checked. If there is limescale in the thermal safety device then it must always be removed.
– Press the red cap against the valve (Fig. 80) > Water must flow out into
the funnel.– Little outflow at funnel > Limescale in thermal safety device (pump limescale remove – e.g. formic acid – through the thermal
safety device).
– Thermal process safeguard dripping > Clean the seal on the piston and
valve seat. If the seal is damaged > Renew the piston.
Note: There is no need to remove the fitting for this purpose!
