4.3 Checking and servicing the thermal discharge safeguard
(Please inform your customer)
Attention!
The function of the thermal discharge 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, it must always be removed.
– Press the red cap against the valve (Fig. 116) > Water must flow out
into the funnel.
– Little outflow at funnel > Limescale in thermal safety device (pump
limescale remover, e.g. formic acid, through the thermal safety device).
– Thermal discharge safeguard dripping > Clean the seal on the
piston and valve seat. If the seal is damaged > Replace the piston.
Note!
There is no need to remove the fitting for this purpose!
