1.1 Operation and control
The Stiebel Eltron domestic hot water
heat pump WWK 300 A/AP/AH/AHP
(DHW) is a DHW generator that operates
automatically and has a capacity of
approx. 300 L. The water temperature is
permanently set to 60 °C.
The device is installed, connected and
handed over ready for use by a qualified
contractor. Nevertheless, you should
familiarise yourself with the most
important technical features of your heat
pump.
1.2 Device description
The device extracts heat from the ambient
air.
This energy is used to heat the water
inside the cylinder. Where the device is
installed inside a room, this is cooled
down through the heat extraction by
approx. 1 to 3 °C. The device also extracts
moisture from the ambient air that creates
condensate, which must be drained off.
For this purpose, a condensate drain with
closure incl. a strainer is integrated in the
floor of the device.
Special features of the WWK 300 AH and
WWK 300 AHP
An electric booster heater is integrated for
heating approx. 100 litres of water in the
upper sector of the DHW cylinder.
1.3 Correct operation
The DHW heat pump is designed for
extracting heat from the ambient air and
the utilisation of that energy for heating
domestic hot water. The DHW heat pump
can be installed in the open as well as in
enclosed spaces.
1.4 Incorrect operation
The following are not permitted:
The utilisation of greasy extract air.—
The heating of liquids other than—
domestic hot water.
The installation of the equipment:—
in rooms where the temperature isa)
below the freezing point.
in rooms where the device is at riskb)
from explosions as a result of dust,
gases or vapours.
Operation of the device with an empty—
cylinder.
1.5 Function description
Heat pump operation
This is the standard operating mode,
to which the limits of scope of the heat
pump apply (see: Specification). To heat
up the cylinder capacity of approx. 300
litres of water in accordance with EN 255
part 3 to 60 °C, the WWK 300 requires ... :
τHeat-up ϑRoom Frel ϑCold water COP (t)
WWK 300 A/AP
10.1 h 15 °C 70 % 15 °C 3.19/3.3
5 h 42 °C 70 % 15 °C 5.61
!
If the heat pump is switched OFF
and ON again, for instance after a
power failure, the compressor will only
re-start (after approx. 3 minutes), when
the pressure inside the refrigerant
circuit has normalised again.
Electric booster heater (only for the WWK
300 AH and WWK 300 AHP)
If there is a higher DHW demand or
the WWK was switched OFF because
you require hot water quickly, you can
accelerate the heat-up process by means
of the electric booster heater. For reasons
of saving energy, the electric booster
heater will only heat up approx. 100 litres
of water in the upper section of the
cylinder.
The control thermostat of the electric
booster heater is preset to 60 °C and will
be restarted when the DHW temperature
falls below 45 °C. This safeguards not only
that primarily the heat pump provides hot
water, but also that you enjoy a high level
of DHW convenience when large amounts
of hot water are drawn.
1.6 Operation with
active defrost feature
WWK 300 A and WWK 300 AH
Subject to the relative humidity and the
DHW temperature, the evaporator begins
to build up hoar frost at an ambient
temperature of below 6 °C.
If the evaporator is covered in hoar frost,
the frost monitor N2 (see wiring diagram
Fig. 6 and 7) switches the fan OFF, whilst
the compressor continues to run, and the
changeover valve V2 routes the hot gas
directly to the evaporator. For this, the
condenser is shut off by changeover valve
V1 (see Fig. 4) When the temperature at
the evaporator fins rises above 3 °C, the
fan is started again, and DHW heating
continues.
The DHW heat pump can be operated at
ambient temperatures as low as 0 °C.
The evaporator is defrosted according to
demand in the temperature range 0 °C to
+6 °C. This extends the heat-up time.
Ambient temperature
!
The heat pump must not be
installed in areas where ambient
temperatures frequently exceed 42 °C
or areas where temperatures frequently
drop below 0 °C
1.7 Operation with
passive defrost feature
WWK 300 AP and WWK 300 AHP
The limit of application of the WWK AP /
AHP (without hot gas defrost feature) is
set to 6 °C.
However, with this limit of application,
the evaporator may build up hoar frost
subject to air temperature and relative
humidity, particularly when the DHW
temperature is low. The compressor
will be switched OFF as soon as the
evaporation temperature lies below -
7 °C for any length of time. When the
temperature at the evaporator fins rises
above 3 °C, the compressor are started
again, and the DHW heating continues.
Ambient temperature
!
The heat pump must not be
installed in areas where ambient
temperatures frequently exceed 42 °C
or areas where temperatures frequently
drop below 6 °C
1.8 Maintenance and cleaning
The device is generally maintenance free,
with the exception of cleaning the strainer
in the condensate drain.
Sand and dust can result in sludge
building up inside the strainer. Therefore,
clean the strainer at least twice per
annum or in accordance with demand.
A damp cloth is sufficient for cleaning
all plastic parts. Never use scouring or
solvent-based cleaning agents.
!
Please note: Maintenance work,
e.g. checking the electrical safety,
must only be carried out by a qualified
contractor.
Check the condensate drain at leastz
monthly at the bottom strainer outlet
and at the top condensate pan drain
(visual check, see Fig. 4, pos 16).
1. Operating instructions for users and contractors

Remove contaminants and blockages
immediately.
For the WWK300 AH and WWK300z
AHP, it is recommended that the
electric booster heater be descaled
from time to time. this will result in
prolonged life fo the electric booster.
Your local contractor, who is familiarz
with the local water quality, should
identify for you the timing of the next
service.
Ask your local contractor to regularlyz
check the safety assembly and the
electric booster heater.
The device is subject to mains waterz
pressure. The expansion water drips
from the safety valve during heat-up.
Inform your local contractor of water
drips from the system after the heat-
up process has ended.
To protect the steel cylinder againstz
corrosion, the interior is coated with
a special enamel and is furthermore
equipped with a protective anode.
Ask your local contractor to check the
protective anode regularly.
1.9 Troubleshooting by the user
No hot water
Should you fail to obtain hot water at any
time, you can take the following steps to
remedy that situation.
No electrical power
Check the fuse/circuit breaker in your fuse
box. If it has blown/tripped, replace/reset
the fuse/MCB. If it should blow/trigger
repeatedly, notify your local contractor.
Still no hot water, even though power is
available
Check, whether the air inlet/outlet is
blocked.
The thermoswitch trips out or the high
limit safety pressure limiter switches
the compressor OFF if the compressor
is overloaded due to excessive ambient
temperature or excessive air temperature
(>42 °C), or because of a fault in the
refrigerant circuit. Ask your local
contractor to remove the fault.
The thermoswitch automatically switches
itself ON again.
!
The high limit safety pressure
limiter must only be reset by your
contractor after he has removed the
cause of the relevant fault.
Other issues
Safety valve of the cold water supply line
drips
This may occur during the heat-up phase
and is completely normal.
The condensate drain drips
This always happens when the surface
temperature of the evaporator is lower
than the ambient dew point temperature.
For all other faults, consult your
contractor.

External installation
The location where the WWK is to be
installed must meet the following
conditions:
Load-bearing floor (wet weight of the—
WWK approx. 430 kg).
Never operate the WWK in rooms at a—
risk from explosion due to dust, gases
or vapours.
It is prefferred that the location of—
the unit is not near a bedroom or
a neighbour´s bedroom. Ideally a
unit may mounted near a kitchen or
laundry. Opposite a neighbours gara-
ge is always prefferred.
The water heater should be located—
as close as possible to the most fre-
quently used hot water tap connec-
tion.
Ensure that the data plate is clearly—
visible.
Internal installation
The room where the WWK is to be
installed must meet the following
conditions:
Load-bearing floor (wet weight of the—
WWK approx. 430 kg).
Never operate the WWK in rooms at a—
risk from explosion due to dust, gases
or vapours.
Include in your considerations the—
utilisation of waste heat, for example
from a boiler, tumble drier or refrige-
rator/freezer.
The available floor area in the instal-—
lation room must be at least 6 m².
Never install this equipment in rooms
with a volume of less than 13 m³.
Never restrict the clearances of the—
WWK through walls and ceilings fur-
ther than illustrated in Fig. 2.
The room temperature must never fall—
below 0 °C, as the ambient tempera-
ture will be reduced by approx. 1-3 °C
through the heat pump operation. The
initial temperature is reached again
approx. ½ h after the heat pump has
been switched OFF.
When installing the heat pump in a boiler
room, ensure that the boiler operation
will not be impaired.
2.3 Water connection
Remove the protective caps from the—
connectors.
With a sharp knife, cut a hole into the—
protective caps and invert over the
pipe to be connected.
Connect the pipe and refit the—
protective caps.
!
Please note: To protect against
the risk of corrosion, make
the connection as flat packing seal.
The use of hemp on connections is
not acceptable.
Insulate the DHW line in accordance with
local regulations.
Accurately maintain the order of fittings
on the cold water side (see Fig. 1).
Air Air
Dimensions in mm
Flush the line prior to installation.
Install a drain valve at the lowest point of
the cold water supply line.
Install a pressure reduction valve when
the water pressure is higher than 500 kPa
(5 bar).
Special measures are required at a water
pressure in excess of 10 bar (see DIN
1988).
Expansion control valve (Fig. 1, pos. 7)
Observe the local requirements for an ECV
(optional)
The diameter of the connecting pipe—
must not be larger than the safety
valve diameter.
Size the drain so that water can drain—
off, even if the safety valve has been
fully opened.
The drain outlet must not be able to be—
closed and must always remain open to
atmosphere.
The safety valve must open at 475 kPa—.
P&T relief valve (Fig. 1, pos. 4)
Atsite: Install the provided P&T relief
valve.
The P&T relief valve must open at 600 kPa.
Condensate drain
The device is designed so that, if it is
installed externally, the condensate
can freely drain away. However, the
condensate can also (in case of internal
installation) be routed into a drain in
the floor or into a wall drain connection
located at a higher point.
Fig. 2
Positioning
C26_03_01_0739

If the condensate is to be routed through
a higher wall outlet, position the heat
pump on a plinth (see Fig. 2), and route a
suitable drain hose on site.
i
Note: Never kink the hose, to
ensure the condensate drains
perfectly.
If required install a condensate pump
(part no. see page 13).
2.4 Power supply
Only qualified electricians must carry out
the installation in accordance with these
instructions.
!
Please note: Before any work,
isolate the equipment from the
power supply at the control panel.
Observe VDE 0100 [or local regulations]
and the regulations of your local power
supply utility.
The appliance is intended to be
permanently connected to fixed wiring.
For the connection to the power supply
the fitted supply cord has to be used. (Fig.
3, pos. 19)”
The DHW heat pump must be able to
be separated from the mains power
supply by an additional isolator, which
disconnects all poles with at least 3 mm
contact separation. For this purpose, use
contactors, mains isolators, fuses, etc. on
site.
Terminals are located inside the control
panel and become accessible by removing
the equipment lid and the cover of the
wiring chamber (Fig. 3).

2.5 Commissioning
Only approved contractors may
commission this equipment and instruct
the owner in its use.
Commissioning
Fill, vent and thoroughly flush the—
device.
Check the safety assembly.—
Inform the user that water may drip
from the safety valve whilst the water
is being heated up.
Switch ON the power supply—
Note:
Never operate the equipment outside—
the temperature range 0 °C to + 42 °C.
At temperatures below - 15 °C
(e.g. transport/storage), the safety
temperature cut-out may respond.
Press the reset button after the
temperature is much higher than
-15 °C (Fig. 3, pos. 3).
2.6 Safety equipment and
maintenance
Only qualified contractors must carry out
the installation in accordance with these
instructions.
On the equipment
In case of a fault, the safety equipment
of the WWK 300 interrupts the relevant
power circuit.
!
Please note: Before any work on
the equipment, disconnect all
poles from the mains.
High limit safety cut-out (STB) electric
booster heater
Equipment with electric booster heater is
stopped if the DHW temperature exceeds
95 °C.
When the source of the fault has been
removed, reset the high limit safety cut-
out by pressing the reset button (pos 2,
Fig. 3).
The heat pump top cover should be
opened for access to this device as shown
in fig. 3.
Safety high pressure limiter (SDBK) Fig 3
The safety high pressure limiter shuts
down the compressor, if the pressure
inside the refrigerant circuit exceeds the
permissible maximum value. The safety
high pressure limiter may also respond,
if the WWK 300 is operated above its
permissible limit (>42 °C air temperature)
or the control thermostat of the heat
pump fails to respond. Reset the high
pressure limit safety cut-out by pressing
the reset button (pos 3, Fig. 3), after the
cause of the fault has been removed.
Protective motor thermoswitch
The protective motor switch will shut
down the compressor, if it is overloaded
because of excessive thermal load.
Remove the relevant fault. The protective
motor switch restarts the compressor
automatically after 5 - 15 seconds.
Protective anode
An anode for the protection of the DHW
cylinder is inserted right in the center of
the heat pump cylinder (item 17, fig.3).
Replace the anode with a new one if
the installed one has been consumed.
When installing the anode, ensure that
the metallic conductor connection is
correctly made. It’s recommended for first
anode inspection to happen after 2 years
after installation. Unless in areas where
total dissolved solids exceeds 400 mg/L
the magnesium alloy anode should be
replaced with an aluminium anode.
Inspections should be more frequent.
Your contractor, who will be familiar with
your water quality, will advise you of the
optimum timing for inspection thereafter.
Should it be impossible to insert a rod
anode, part no. 143496 from above, you
may have a sectional anode installed
instead.
Cleaning the evaporator
Maintaining the full output of the WWK
300 requires an occasional professional
cleaning of the evaporator. Clean the
evaporator only with water and a brush.
Never use acidic or alkaline cleaning
solutions.
Further information regarding the
equipment:
Cleaning and descalingz
After removing the plug or the electric
booster heater (if installed), clean
the cylinder through the inspection
aperture.
Use a descaling pump to descale the
cylinder. Connect the pump between
the cold water connection and the
inspection aperture. Ensure that the
protective anode is removed prior to
descaling. When installing the anode,
ensure that the metallic conductor
connection is correctly made.
zDraining the cylinder:
Close the shut-off valve in the cold—
water supply.
Fully open the hot taps at all draw-—
off points.
The cylinder is drained via the cold—
water inlet line. Residual water
remains in the lower part of the
cylinder.
i
Note: Hot water can be expelled
during draining.
On the system
Safety valve (on-site)
This valve opens when the water pressure
exceeds the preset value of 600 kPa
(6 bar) thereby relieving the pressure. It is
adjusted so that no water will be expelled
when heating is switched OFF. Should it
continue to drip excessively, either the
valve seat has become contaminated, the
water pressure is too high or the pressure
reducing valve has become faulty.
Pressure reducing valve (on-site
provision)
Check the valve for perfect function.
Replace it, if required.
Regular valve maintenance
Safety requires that valves are regularly
checked for perfect function. For this,
regularly vent the safety valve until a full
stream of water flows from it. Close the
safety valve after checking.
How quickly limescale builds up depends
on the local water quality.
As your local contractor is familiar
with your local water quality, let him
determine the timing of this check.

WARRANTY - Australia only
Stiebel Eltron (Aust) Pty Ltd warrants the domestic range of heat pump
water heaters (WWK300 and WWK300 A) to be free from defects in mate-
rial and workmanship under normal use and service in accordance with
the following terms:
1. Repair or if necessary replace the water heater, or
2. Replace any component which falls within the warranty period as
specified below (subject to the conditions and exclusions thereafter
referred to)
~ 5 years for the cylinder and condenser
~ 2 years for the sealed refrigeration system, including compres-
sor, evaporator, valves and associated pipe work.
~ 1 year for all other componentry (electrical)
The above shall not apply to such water heaters or part thereof which,
in our opinion, have been subject to any accident, alteration, abuse or
misuse or have suffered any damage by flood, fire or act of God, or if
any repairs have been made or attempted to be made by any person or
persons not approved by us. The warranties shall not extend to any loss
suffered by, or resulting from, the non-operation of the water heater or
part thereof.
We will not incur any obligation or liability whatsoever under the war-
ranties for any damage or harm which may arise directly or indirectly
as a result of the water heater being installed by other than registered
qualified plumbers or being connected to a water or power supply not
in accordance with the regulations of the relevant electric, water and
health authorities.
The following items 1-5 are specifically excluded from the normal
terms of warranty.
1. Damage as the result of transportation, removal, or storage.
2. Damage due to connection to incorrect water supply, incorrect in-
stallation or faulty valve.
3. Damage or faulty operation due to foreign matter in the water sup-
ply.
4. Damage or faulty operation due to the corrosive elements in the
water supply and proper precautions not having been followed (eg,
anode inspection & change). Void of warranty can be even if anode
is changed with high minerals in the water or total dissolved sol-
ids exceeds 400 mg/L. Warranty void with use with bore, dams or
swimming pool water.
5. Damage or faulty operation due to incorrect installation where the
air flow, to and/or from the unit, is restricted or impeded
Not withstanding anything contained herein, the units shall continue to
be subject to any implied warranty provided by the Trade Practices Act
1974 (as amended) if and to the extent that the said Act is applicable
and prevents the exclusion, restriction or modification of that warranty.
This free service will apply, in principle, to metropolitan and other ac-
cessible areas. If the unit is located in a remote area an extra service
charge may be applicable due to travel.
Service costs by others are not covered by the Warranty and are at the
user's expense. In the event of any claim being made under the war-
ranty, it is the original purchaser's responsibility to provide evidence of
purchase and date of purchase.
A nominal service charge may be made should the appliance be found
to be in normal working condition and the problem located elsewhere.
