Installation
Hot Water Storage Tank with Coil
WTB 220-400
The storage tanks can be installed in any room protect-
ed against a temperature drop below 0°C, which will
prevent freezing of water in the tanks. It should be in-
stalled in a convenient place for the user (eg basement,
boiler room, etc.), in a way that will enable easy main-
tenance or servicing in the future. However, we recom-
mend installation of the tanks in the immediate vicinity
of the main heat source in order to avoid unnecessary
heat losses. Consider the fi lled tank weight when select-
ing its location. As a rule, select the device location in a
way allowing the rational routing of both the hot water
and the heating lines. To avoid loss of heat energy, all
hydraulic pipes should be thoroughly insulated.
Removable housing with thermal insulation facilitates
transport and installation of the storage tank. Disas-
sembly the housing in the following order (see Fig. 6):
After the installation of the storage tank in its fi nal lo-
cation, reinstall the removed components in the re-
verse order.
The storage tank stands on three feet that can be adju-
sted within the range from 0 to 15 mm to level the tank.
1. Remove the Temperature gauge, plug of the
heating element connector pipe and blanking
plate of the inspection opening.
2. Remove the upper cover of the housing together
with thermal insulation.
3. Remove the plugs from the connector pipes and
black bushings.
4.
Remove the fi xing screws and the strip connect-
ing the housing jacket.
5.
Remove the jacket surrounding the tank (housing
jacket.)
6. Remove the four-piece thermal insulation.
If space for the installation of the magnesium bar an-
ode (used as standard), you can use the appropriate
titanium anode (that should be installed in accordance
with the anode manufacturer’s instructions) or the ap-
propriate magnesium chain anode. For the specifi ca-
tion of the protective anodes available at Nathan Sys-
tems B.V., see Section “Accessories and Spare Parts”.

NOTE
When installing the storage tank, consider
free space above the unit required to ma-
intain/replace the protective magnesium
anode.
Caution
For the minimum clearances to be ob-
served when installing the storage tank,
see Table 5.
NOTE
You can decrease the Amin clearance when
using the magnesium chain anode or tita-
nium anode.
