7.4

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 expansi-

on 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.

7.5

• 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).

7.6

• Instruct the operator of the system in the handling

and function of all the equipment.

• Hand over all the instruction manuals and documents

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.
