AHP/AHPS/AHPHChapter 3 | Accumulator tank design8

General
Pipe installation must be carried out in accordance with
current norms and directives.
Internal support bushes must 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 appro-
priate 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
When installing in a pressurised system, the system must
be equipped with a pressure expansion vessel pre-pres-
surised to 0.5 bar (5 mvp).
Internal volume in AHP/AHPS/AHPH for calculating ex-
pansion 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 ves-
sel
Total volume (l) (accumu-
lator tank and radiator
system)
50500
70700
1001000
NOTE
Expansion vessel not supplied with the product.
The pre-pressure of the pressure expansion vessel must
be dimensioned according to the maximum height (H)
between the vessel and the highest positioned 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 5.
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
is connected to AHPS / AHPH.
AHPS
AHPS consists of a vessel with a number of connections,
which make 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 retrieve 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.
AHPH
AHPH consists of an accumulator tank with integrated
tap coil for hot water. AHPH can be docked to an external
heat source, for example heat pump.

NOTE
Electrical installation and service must be carried
out under the supervision of a qualified electri-
cian. Electrical installation and wiring must be
carried out in accordance with the stipulations
in force.
Sensors
AHP/AHPS/AHPH 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/AHPH)
1. Open a hot water tap in the house.
2. Fill the hot water coil through the cold water connec-
tion (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 be-
fore 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 exiting 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.
6. AHPH is filled through connection XL9, when water
runs out of the XL8 connection, the reservoir is full.
Venting
For installations with several AHP/AHPS/AHPH it is im-
portant 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 accumu-
lator tank. Contact your installer if you are un-
sure how one checks the valve.
Emptying
AHP and AHPH: The vessel is drained via docking connec-
tion (XL19).
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 connec-
ted.
The hot water coil in AHPS and AHPH is emptied through
the siphon (with hose) in the cold water connection
(XL3).
Drain the solar coil in AHPS through the siphon (with
hose) on the connection, return to solar heating system
(XL14).
