Pipe installation
GENERAL
NOTE
Pipe installation must be carried out in accord-
ance with current norms and directives
An internal support bush must be fitted when a plastic
or annealed copper pipe is used.
Water may drip from the safety valve’s overflow pipe.
The entire length of the overflow water pipe must be
routed to a suitable drain and be inclined to prevent
water pockets, and must also be frost-proof. The over-
flow pipe must be at least the same size as the safety
valve. The overflow pipe must be visible and its mouth
must be open and not located close to electrical com-
ponents.
Caution
Ensure that incoming water is clean. When
using a private well, it may be necessary to
supplement with an extra water filter.
SYSTEM DIAGRAM
VPB S/ VPBS S is a series of water heaters that are
suitable for connection to e.g. a heat pump.
VPB S/ VPBS S consists of a hot water tank with internal
anti-corrosion protection made of copper, stainless steel
or enamel, as well as a charge coil
The charge coil heats the domestic water, resulting in
excellent properties for hot water charging.
VPBS S300 has an additional coil, which is used for an
external heat source, e.g. thermal solar panels or a stove
with a back boiler.
