General
Pipe installation must be carried out in accordance with
current norms and directives.
Internal support bushes should be fitted when a plastic
or annealed copper pipe is used. The accumulator tank
must be fitted with the requisite valves, such as a safety
valve, shut-off valve and non-return valve. An overflow
pipe should be routed from the safety valve to an ap-
propriate drain. The overflow pipe must be the same
size as the safety valve. Route the overflow pipe from
the safety valve enclosed along its entire length and
ensure that it is frost proof. The mouth of the overflow
pipe must be visible and not placed close to electrical
components.
Maximum boiler and radiator volumes
For installation in pressurized systems, the system must
be equipped with a pressure expansion vessel pre-
pressurised to 0.5 bar (5 mvp).
Internal volume in AHPS for calculating expansion
vessel is 270 l. The expansion vessel's volume must be
at least 10 % of the system's total volume.
Example table
Volume (l) expansion
vessel Total volume (l) (accumu-
lator tank and radiator
system)
50 500
70 700
100 1000
NOTE
Expansion vessel not supplied with the
product. Equip the product with an expansion
vessel.
The initial pressure of the pressure expansion vessel
must be dimensioned according to the maximum
height (H) between the vessel and the highest posi-
tioned radiator. A pre-pressure of 0.5 bar (5 mvp)
means a maximum permitted height difference of 5
m.
If the pre-pressure in the pressure vessel is not high
enough it can be increased by adding air via the valve
in the expansion vessel. The expansion vessel's pre-
pressure must be entered in the check list on page 4.
Any change in the pre-pressure affects the ability of
the expansion vessel to handle the expansion of the
water.

AHP
AHP consists of a vessel with accumulated volume. AHP
connected to AHPS.
AHPS
AHPS consists of a vessel with a number of connections,
which makes it possible to dock the accumulator tank
to external units. By using the different levels in the
tank, heat can be retrieved and supplied to the tank in
several versions. Use for example level 2 and 3 to re-
trieve solar heat to heat a pool. The heat between level
2 and the top of the tank is then intended to preheat
the hot water to the heat pump.
