The add

-on components are packed in the tank mounts:

•

"DV" degassing valve (2) with reducing sleeve

•

"VE" equalisation elbow (1)

•

"LIS" pressure pick-up

For add

-on components, proceed as follows:

. Seal the "DV" degassing valve and the reducing sleeve.

. Connect the degassing valve with the reducing sleeve.

. Install the degassing valve at the connection of the corresponding tank.

. Remove the protective cap from the "DV" degassing valve.

. Use the clamping ring screw connection to install the "VE" equalisation elbow for aeration and

ventilation at the tanks.

The add

-on components are installed.

Note!

Install the "LIS" pressure pick

-up only after finalising the installation of the primary tank.

Note!

Do not seal off the "VE"

aeration and ventilation to ensure fault-free operation.

•

Ensure rectangular and free-standing position of the tanks.

•

Use only tanks of the same type and dimensions when

using secondary tanks.

•

Ensure proper functioning of the "LIS" level sensor.

– Do not attach the tanks to the floor.

•

Install the control unit on the same level as the tanks.

Install the thermal insulation (2) around the primary tank (1)

and close the insulation with the zip fastener.

Note!

For heating system

s, insulate the primary tank and the "EC" expansion lines against heat loss. The cover of the primary

tank does not require insulation, as there is space between the diaphragms and the tank wall.

The secondary tanks do not

require insulation either.

Note!

Condensate formation requires insulation by the user.
