Buffer storage tank installation
The buffer storage tank should be installed on a flat floor surface. Ensure
that the bottom of the tank is fully in contact with the floor. Care should
be taken not to damage the metal casing of the tank.
Ensure that the floor is dry and the outside of the storage tank cannot get
wet during its lifetime. The insulation will be damaged if left in contact
with water.
If the buffer storage tank cannot be mounted on a flat floor surface (for
example if the tank is mounted on a wall frame) the tank must first be
placed on top of a suitable metal plate. The bottom of the tank must be
fully in contact with the metal plate and completely cover the tank
bottom.

4.2
Industrial location
▶ Observe minimum clearances.
▶ Place storage tank on an even and load-bearing ground.
▶ In damp rooms: put storage tank on a platform.
▶ Recommend minimum clearance of 25mm around the tank.
▶ Ensure you have adequate access to the drain valve.
DANGER:
Risk of injury from carrying heavy weights!
▶ Do not try to lift or carry the storage tank alone.
CAUTION:
Damage from inappropriate protection
during transport!
▶ For transport, use appropriate means, e. g. a sack
truck or pump truck with a tension belt.
NOTICE:
Protect from freezing!
▶ Place storage tank in a frost-proof room.
▶ Ensure the tank is frost protected.
▶ Insulate pipes with class O insulation.
NOTICE:
Damage from corrosion!
▶ Use the storage tank in sealed systems only.
