4 Installation
4.1 Installation location
 Condensate drainage (with a siphon) must be provided.
 The condensate must be discharged without frost.
 The air taken in may not be excessively contaminated or
contain large amounts of dust.
 The load-bearing capacity of the foundation must be suffi-
cient (the weight of the domestic hot water heat pump is ap-
prox. 440 kg!).
For fault-free operation and for any maintenance and repair
work, minimum clearances of 0.6m are required on all sides of
the device. If the BWP is installed in any kind of enclosure, the
clearances set out in the figure must be maintained
ATTENTION!
If devices are installed in locations with a risk of frost and are no longer
operated or will not be connected to the power for a long period (several
hours), the water must be drained from the cylinder. If this is not done,
frost may destroy the device.
4.2 Installation
 Remove the three transport restraint screws (M12 - fixing
the device to the pallet) from the bottom of the pallet.
 Remove the pallet and mount the three M12 supporting feet
(in the plastic bag attached to the nipple of the cylinder pipe).
 Position the domestic hot water heat pump and align it verti-
cally by adjusting the device feet. Then tighten the counter
nuts on the device feet.
5 Assembly
5.1 Connecting the water pipes
The water connections (see Cap. 1 on pag. II) are located on the
rear of the unit.
Important information:
Circulation pipe
For energy efficiency reasons, a circulation pipe should not be
used if this can be avoided. If a circulation pipe is installed in the
domestic hot water distribution system, a valve or a similar de-
vice must be provided as shut-off facility to avoid unnecessary
energy losses. Circulation is enabled according to use (time or
requirement control).
The nominal pipe widths for the on-site sanitary installation must
be determined by taking into account the available water pres-
sure and any pressure drops expected to occur in the pipework.
Water installations must be executed according to the Australian
standard AS 3500.4, also observe local regulations for domestic
water installations!
The heat pump must be permanently connected to the water
mains! Both rigid and flexible water pipes may be used.
Install a
5
00 kPa pressure and temperature relief valve
(PTRV)(see Cap. 2.3 on pag. IV)
Observe the corrosion behaviour of the pipework materials used
in order to avoid corrosion damage (see section "Commission-
ing").
Pipe nipples (on the cylinder) and water pipes must be protected
from frost!
The pipe nipples are protected from corrosion with a heat shrink-
able tubing. In the connection thread area, the heat shrinkable
tubing should only be removed as far as necessary. The transi-
tion or interface area should be protected (e.g. with silicon) to
provide corrosion protection.
A safety valve (PTR valve) must be mounted on-site by the in-
staller. This valve must not be lockable and must not have a shut-
off device.
NOTE
Domestic hot water, cold water, circulation connections:
These pipe nipples contain plastic inserts, the purpose of which is to
protect against corrosion (in particular to the pipe nipple flange
surfaces). These plastic inserts remain in their positions after installation.
NOTE
When installing the on-site pipework, ensure that the pipes are not
contaminated (flush pipes before connecting the domestic hot water heat
pump if necessary)!
NOTE
The PTR Valve must be installed as per the Hydraulic
Drawing on page A-IV. Both the PTR Valve and Pressure
Reduction Valve must comply with AS1357.1
