1.1 Getting started
Installation
The accumulator tank should stand on a solid surface and be leveled with assistance from the setscrews underneath the tank (not fitted
on all models). The tank models that come without setscrews can be leveled with assistance of a shim. This must be done before the
tank is connected to the pipes and filled with water. The setscrews can be adjusted down to a maximum of 25mm. Connections not in
use must be plugged appropriately. During water filling, condensed water may emerge on the outside of the tank. This will result in
water underneath the tank, on the floor. This will cease when the tank is heated. There must be a floor drain in the same room.
To temporarily remove the insulation, for instance if there is a narrow passage to fit the tank through, see the below instructions (not
applicable to all models). All the screws holding the insulation in place is of Torx 10 type.

2. Maximum length between floor and tank is 39mm, in-
cluding foot.
3. Maximum screw length is 25mm, excluding foot.
Commissioning
Start by filling the tank, then pressurize it. Continue to fill the radiator system (the enclosed water). The working pressure may not ex-
ceed the test pressure (4,3 or 8,6 bars, gauge). A safety valve with releasing pressure of that of the test pressure must always be installed.
Maintenance
Check the safety valve annually by manually opening and closing the valve handle and making sure that water is released. Check annu-
ally all connections for eventual leakage (also peripheral installations, i.e. a heat pump, etc).
