9Chapter 3 | Accumulator tank designAHP/AHPS

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)
50500
70700
1001000
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.

NOTE
Electrical installation and service must be car-
ried out under the supervision of a qualified
electrician. Electrical installation and wiring
must be carried out in accordance with the
stipulations in force.
Sensors
AHP/AHPS can be supplemented with up to two hot
water sensors. These are placed in the submerged tube
for hot water sensor (UA1) and (UA2).
AHPS can also be supplemented with a solar sensor.
This is placed in the submerged tube for solar sensor
(UA3).
Use the sensors provided with the heat pump (or other
heat source). When no heat sensors have been
provided these must be ordered from the manufacturer
of the heat source.

5 Electrical installation

Filling and venting
Filling the hot water coil (AHPS)
1. Open a hot water tap in the house.
2. Fill the hot water coil through the cold water con-
nection (XL3).
3. When the water that comes out of the hot water
tap it is no longer mixed with air, the hot water coil
is full and the tap can be closed.
Filling the solar coil (AHPS)
Fill the solar coil through the filling connection in the
solar panel unit.
There must be water in the solar coil and the vessel
before the solar panel unit is operated.
Filling the vessel
1. Open the externally mounted vent valve
(CP2-QM60).
2. Fill the vessel in AHPS through the drain valve
(QM1).
3. When the water that exits the vent valve
(CP2-QM60) is not mixed with air, the vessel is full.
4. Close the vent valve (CP2-QM60).
5. AHP filled indirectly when AHPS is filled.
Venting
For installations with several AHP/AHPS it is important
to vent the connection between the tanks.
1. Vent through the externally mounted vent valve
(CP2-QM 60) .
2. Keep topping up and venting until all air has been
removed and the pressure is correct.

Service actions
Safety valve
The hot water coil's externally mounted safety valve
sometimes releases a little water after hot water usage.
This is because the cold water, which enters the hot
water coil, expands when heated causing the pressure
to rise and the safety valve to open.
The function of the safety valve must be checked regu-
larly. Perform checks as follows:
1. Open the valve.
2. Check that water flows through the valve.
3. Close the valve.
TIP
The safety valve is not supplied with the accu-
mulator tank. Contact your installer if you are
unsure how one checks the valve.
Emptying
AHP: The vessel is drained via docking connection
(XL19) in AHP.
AHPS: Empty the vessel via the drain valve (QM1).
AHP and AHPS: The vessel is drained via the drain valve
(QM1) in AHPS, in those cases AHP and AHPS are con-
nected.
The hot water coil in AHPS is emptied through the si-
phon (with hose) in the cold water connection (XL3).
Drain the solar coil through the siphon (with hose) on
the connection, return to solar heating system (XL14).
