with a solar heating system, a
15
DHW temperature of over 60 °C can occur
15
at the outlet.

Small children should be kept away from
such outlets.

z
The freestanding DHW cylinder, safety
15
assembly and built-in accessory
components should be checked regularly
15
by your local contractor.

These units are under water mains
pressure. During the heating process,
expansion water will drip from the safety
valve. If water continues to drip when
heating is completed, please inform your
local contractor.
z
Internally the steel cylinder has a
special enamel coating to protect it
from corrosion; it also has a protective
anode with consumption display (display
element). Once the signal anode is used
up, humidity reaches the display element
(14), causing a colour change.

1.3 Unit description
Freestanding DHW cylinders
SBB...WP and SBB...WP SOL are specially
designed for heating DHW with heat pumps.
The heat from the heat pump's heating water
is transferred to the DHW by bare-tube internal
indirect coils in the cylinder.
Refer to the heat pumps' engineering
documents for information on sizing the
freestanding DHW cylinder.
Special features of the SBB 401 WP SOL and
SBB 501 WP SOL
The DHW cylinder is also equipped with a
second internal indirect coil for solar DHW
heating.
1.4 Maintenance and care
!
carried out by a qualified contractor.
z
Almost every type of water deposits lime
at high temperatures. This is deposited
within the cylinder and on the integral
components, affecting their function and
service life. The integral components
should therefore be descaled from time
to time.
Your local contractor will know about the
local water quality and will tell you when
a service is due.
z
A damp cloth is all you need to care for
the plastic parts. Never use abrasive or
corrosive cleaning agents.
