PrimoBox ACB 910 mixing unit for condensing boilers
6.2
Flush mounting
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
the unit
housing.
Then
create
a
space
in the wall, at least 2 cm larger
than the external dimensions
of the housing of the ACB 910
mixing unit. Fasten the module
in the hole in the wall
with plaster or other suitable
compound. Remember to level
it carefully using a spirit level.
After
drying,
if necessary,
make an aesthetic finish of the
wall.

Hydraulic connections
Before connecting the PrimoBox ACB mixing unit, flush the system
thoroughly, paying special attention to removing residue from solder-
ing, cutting pipes, etc. Make sure that the installation contains safety
components
neces-sary
for
proper
and
safe
functioning.
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).
6.3.1
Connection to the heat source
The connection between the ACB unit and the heat source is made
via supply and return connections with G
¾" male threads located
in the upper part of the ACB unit.
