Bleeding the brine circuit.
To bleed the brine circuit, activate the "Brine bleeding"
menu point in Menu A7. The brine pump now alternates
between 50 minutes operation and 10 minutes standstill.
Check whether the fluid level in the brine expansion
tank has stabilised.
• Let the brine pump continue to run, so that the air
trapped in the system can be collected in the expan-
sion tank. The level of the fluid in the expansion tank
falls as a result of the discharge of air and must be
topped up again as described in Chap. 5.2.
• Open the expansion relief valve to allow any possible
overpressure to discharge. The tank must be filled to
2/3 full with fluid.

Bleeding the heating circuit
• If manual switching of the heating circuit pump and
the 3-way valve is necessary to bleed the heating cir-
cuit, perform this via Menu A5/A6 (see Table 8.4).

for the appliance to the operator for safe keeping.
• Tell the operator to keep the manuals nearby the con-
troller. Inform the owner of the need for regular in-
spection of the system.
