Connection to the heat source

Check whether the wall is strong and thick enough and that

the PrimoBox ACB 910 mixing unit will fit in the place you choose.

To install the PrimoBox AZB mixing unit in the wall, breach the fins

placed in the housing and bend them with pliers so that they are

outside

create

in the wall, at least 2 cm larger

than the external dimensions

of the housing of the ACB 910

mixing unit. Fasten the module

the

hole

with plaster or other suitable

compound. Remember to level

it carefully using a spirit level.

After

drying,

make an aesthetic finish of the

wall.

Before connecting the PrimoBox ACB mixing unit, flush the system

thoroughly, paying special attention to removing residue from solder-

components

neces-sary

You should also check on the basis of flow charts whether the required

flow on individual heating circuits will be guaranteed. We recommend

installing strainers before inlet connections. The heating installation

should also contain dirt separators or other similar filter elements.

Make sure you can use the PrimoBox ACB mixing unit for the circuits

connected to it. Remember that the ACB unit is intended for the distri-

bution of the medium into the radiator installation (without mixing)

and the underfloor heating installation (with qualitative temperature

regulation by mixing).

The connection between the ACB unit and the heat source is made

via supply and return connections with G¾" male threads located

in the upper part of the ACB unit.
