1 Operation and control
The WWK 300 domestic hot water (DHW) heat
pump from STIEBEL ELTRON is an automatic
DHW heater offering a capacity of approx. 300
l. The required DHW temperature can be pre-
selected.
Your local contractor will install, connect and
commission your WWK. Nevertheless, you
should familiarise yourself with the most
important aspects of this equipment.
1.1 Equipment description
The WWK 300 contains two heat sources
within the cylinder; both heat the water to the
required temperature:
– Heat pump
– Electrical supplementary heater
The WWK 300, with suffix SOL, not only
contains a heat pump and an electrical
supplementary heater, but also a heat
exchanger permanently fitted inside the
cylinder, which can be supplied with energy
from a boiler or solar heating system.
The WWK 300 extracts energy from the air
which can be utilised to heat the water
contained inside the cylinder. This energy
extraction leads to a cooling of the installation
room by approx. 1-3 °C. The WWK can also
be operated with a connection to an air duct
(for part no., see page 2). However, such air
channels must not be smaller than Ø 160 mm;
their length should not exceed a maximum of
approx. 5 m.
The WWK 300 also extracts moisture from the
air, which turns into condensate and must be
drained off. A hose connection is provided for
that purpose.
1.2 Correct operation
This DHW heat pump is designed to extract
energy from the air inside the equipment
installation room or from a room, to the
ambient air of which it is connected, via air
ducts. With that energy it heats domestic hot
water (DHW).
1.3 Incorrect operation
Never
– use greasy exhaust air
– heat liquids other than potable water
– install the equipment
a) outside
b) in rooms at risk from frost
c) in rooms at risk from dust, gases
or vapours liable to explode
– operate the equipment with an empty
cylinder
– operate the integral heat exchanger
inside the equipment cylinder with
liquids other than heating water.
1.4 Description of functions
1.4.1 Heat pump operation
This is the standard operating mode, to which
the limits of scope of the heat pump apply
(see: specification). To heat the cylinder
content of approx. 300 litres of water to 55 °C,
the WWK 300 (to EN 255 part 3) requires:
ϑ Space H rel ϑ Cold water τ Heat-up COP(t)
6 °C 70 % 15 °C 11.5 h 3.3
15 °C 70 % 15 °C 9.0 h 4.2
35 °C 47 % 15 °C 6.4 h 5.2
The water inside the cylinder will be heated to
55 °C by the electrical supplementary heater,
which is controlled by the programmable
time switch, subject to the heating period
being long enough. This enables the option
of making greater mixing water volumes
available at certain times. At all other times,
the water will be heated to the temperature
selected on the controller (see page 4, Fig. 1,
item 3).
If the heat pump was manually swit-
ched OFF and ON again after a power
failure, the compressor will only
re-start (after approx. 15 minutes) when the
pressure inside the refrigerant circuit has
normalised again.
1.4.2 Electrical supplementary heater
You can accelerate the heating-up process
with the electrical supplementary heater, if the
DHW demand increases or if the WWK 300 has
previously been switched OFF and you require
hot water as quickly as possible. For reasons
of saving energy, the electrical supplementary
heater only heats the top third of the cylinder
capacity (approx. 100 litres). This takes approx.
2 hours.
In SOL versions, approx. 50 litres are heated
up due to the flange being positioned higher
up on the cylinder.
The electrical supplementary heater is
switched ON when the actual temperature falls
below 58 °C and is switched OFF when 65 °C
are exceeded.
Press the push button only once if you want to
activate the electrical supplementary heater
only to cover a peak demand.
1.4.3 Boiler operation via heat exchanger
(only for SOL version)
A heat exchanger, which is generally
connected to a central heating system, is
integrated into the cylinder. Subject to the
heating water flow temperature, the entire
cylinder capacity should be heated up by the
heat exchanger in between 3 and 4 hours.
Never exceed the maximum inlet tem-
perature of 65 °C into the heat pump
heat exchanger.
1.5 Operation outside the limits of use below
6 °C to 4 °C
Subject to the relative humidity and the
DHW temperature inside the cylinder, the
evaporator begins to ice up below a room
temperature of 6 °C. When the evaporator
is covered in hoarfrost, the frost stat N2 (see
wiring diagram) shuts down the compressor,
whilst the fan continues to operate, thereby
defrosting the compressor. The compressor
starts again automatically after the defrosting
process has been completed, and the heat
pump operation continues.
The minimum temperature required for the
heat pump operation is +4 °C. The evaporator
is defrosted upon demand at operating
temperatures between +4 and
+6 °C. This increases the heat-up time.
Room temperature higher than 35 °C
The heat pump will be switched OFF by safety
equipment at room temperatures above
approx. 35 °C. The heat pump will be re-
started automatically after a brief cooling
down period. The heat pump will be switched
OFF again if the room temperature is still
higher than 35 °C.
Take appropriate steps to prevent
the ambient temperature rising
above 35 °C.
1.6 Maintenance and cleaning
The WWK 300 is largely maintenance free.
Maintenance must only be carried out by
qualified contractors.
Have the protective anode checked regularly.
Your contractor, who will be familiar with
your local water quality, will advise you of the
optimum timing for such maintenance. The
first inspection of the protective anode is due
after two years.

1.7.2 Description of functions
– Switch (1) switches the entire heat pump
ON (I) or OFF (0).
– Using push button (2), you can activate
a single quick heat-up of the cylinder via
the electrical supplementary heater. After
the top third of the cylinder capacity has
reached a DHW temperature of 65 °C, the
electrical supplementary heater is switched
OFF, but is not automatically switched ON
again.
– An indicator lamp is integrated into push
button (2), which lights up when the
electrical supplementary heater is switched
ON.
– Select the DHW temperature with the rotary
selector (3) of the thermostat,
Fully clockwise approx. 55 °C
ECO approx. 40 °C
(frost protect. stage) approx. 25 °C
In position ECO, the heat pump operates more
efficiently than at the r.h. end stop. You will
need to establish the DHW temperature you
require, because a higher temperature would
result in a larger volume of DHW at approx.
40 °C (temperatures for baths and showers are
generally around 40 °C).

temperature inside the upper third of the
cylinder (approx. 100 litres).
1.8 Troubleshooting by the user
1.8.1 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. Notify your local contractor, if the
MCB trips/fuse blows again when you insert
the mains plug into the socket again.
Still no hot water, even though power is
available
Check, whether the air inlet/outlet is
unobstructed.
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 extract temperature
(>35 °C), or because of a fault in the
refrigerant circuit. Ask your local contractor to
remove the relevant fault.
The thermoswitch automatically switches itself
ON again.
The high limit safety pressure limiter
must only be reset by your contrac-
tor after he has removed the cause of the
relevant fault.
1.8.2 Other faults
Safety valve of the cold water supply line drips
This may occur during the heat-up phase and
is completely normal.
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.
DHW heating can be maintained in most
fault conditions by switching the electrical
supplementary heater ON.

Installation instructions for contractors
2 Safety equipment and
maintenance
2.1 On the equipment
In case of a fault, the safety equipment of the
WWK 300 interrupts the relevant power circuit.
Such faults can, for example, be
caused by a faulty DHW priority
setting on a connected boiler.
Pull the mains plug out its socket before
commencing any work on the equipment.
High limit safety cut-out (STB)
This will shut the equipment down if the
DHW temperature exceeds 95 °C. Reset the
high limit safety cut-out by pressing the reset
button (item 2, Fig. 3), after the cause of the
fault has been removed. For this, open the
equipment as shown in Fig. 2a.
Safety high pressure limiter (SDBK)
The safety high pressure limiter shuts down
the compressor, if the pressure inside the
refrigerant circuit exceeds the permissble
maximum value. The safety high pressure
limiter may also respond, if the WWK 300 is
operated above its permissible limit (>35 °C
exhaust temperature). Reset the safety high
pressure limiter by pressing the reset button
(item 1, Fig. 3), after the cause of the fault has
been removed. For this, open the equipment
as shown in Fig. 2a.
Protective motor switch
The protective motor switch will shut down
the compressor if it is overloaded because of
excessive thermal load. Remove the relevant
fault. After a short while, the protective
motor switch will restart the compressor
automatically.
Protective anode
A protective anode is integrated into the DHW
cylinder to protect it against corrosion.
The protective anode is pushed through the
flange from inside out and secured. For
inspections, the flange will be removed to
enable the simultaneous inspection of the
electrode, the heater rod and the internal
enamel coating. When replacing the anode,
ensure a perfect contact with a metallic,
conductive surface during assembly. The
timing of the inspection is subject to the local
water quality and is determined by your local
contractor (Stiebel Eltron recommends that the
first inspection takes place no later than after
two years).
The protective anode is located behind the
front fascia. When removing the fascia, please
note that the earth strap to the fascia is not
pulled off (Fig. 2b). If required, remove the
strap from the push-on connector.
When replacing the front facia en-
sure that the earth cable is correctly
connected.
Cleaning the evaporator
Maintaining the full output of the WWK 300
requires an occasional professional cleaning of
the evaporator. Your contractor will determine
the timing for this operation.
2.2 On the system
Safety valve (on-site provision)
This valve opens when the water pressure
exceeds the preset value of 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 necessary.
Regular valve maintenance
Safety requires that valves are regularly
checked for perfect function. 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.

The available floor area in the installation
room must be at least 6 m². Never install
this equipment in rooms with a volume of
less than 13 m³.
Never restrict the ambience around the
WWK 300 through walls or ceilings closer
than shown in Fig. 4.
The room temperature must never fall
below +6 °C, as the ambient temperature
will be reduced by approx. 1-3 °C through
the heat pump operation. The initial
temperature level will be re-established
approx. ½ hour after the heat pump has
been switched OFF.
When installing the heat pump in a boiler
room, ensure that the boiler will not be
impaired.
3.3 DHW connection
Observe the regulations imposed by your local
water board. Install the cold water supply line
in accordance with Fig. 5.
To facilitate an easy connection to the water
system, the equipment will be supplied (in a
separate pack) with angled plug-in fittings,
pipe connectors with union nuts and flat
gaskets.
Fitting the plug-in connector (see page 9.)
To protect against the risk of cor-
rosion, make the connection as flat
packing seal. The use of hemp on connec-
tions is not acceptable.

safety assembly
We recommend the following combinations
when using metal pipework for the
installation:
Cold water line DHW line
Copper pipe Copper pipe
Steel pipe Steel or copper pipe
Insulate the DHW line in accordance with local
regulations.
Please adhere to the order of fittings on the
cold water side precisely (see Fig. 5). Prior to
installation: Flush out the line.
Install the safety valve into the cold water line.
The expansion water must be able to be seen
to drip into a basin or funnel. 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
outlet must not be able to be blocked/closed
off. The safety valve must open at 6+1 bar.
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 5 bar. Special
measures are required at water pressure
above 10 bar (see Fig. 5).
Condensate drain
The condensate from the WWK 300 is
channelled to a drain via a hose (½” dia.).
Where necessary, install a condensate pump
(for part no., see page 2).
Connecting a circulation line to the cylinder
The heat losses incurred in the circulation
line and the electrical power consumption of
the circulation pump, reduce the efficiency
of the system. The cooled down water in
the circulation line mixes with the cylinder
content. Where possible, avoid installing a
circulation line. Where that is not possible,
control the circulation pump thermally or by a
time switch.
3.4 Boiler connection
(WWK 300 SOL)
Pipe bends with union nuts are supplied
with equipment which has heat exchangers
installed, to enable easy connection to a
boiler.
Such connection is only permitted with boilers
providing DHW priority and in conjunction
with an electronic temperature sensor
operating with low voltage (capturing the
cylinder temperature of the heat pump).
The sensor well is located on the front of the
heat pump behind the lower door. The DHW

4 Commissioning
Your local contractor must implement the
commissioning: Fill the cylinder to prevent
damage to the compressor and radiators. For
filling, open the water valve, until water flows
out.
Open the safety valve, until water flows out
free of bubbles. Then close the safety valve.
– Starting the WWK 300:
Set switch 1 to ON.
– Supplementary heater: Press push button
2; the indicator lamp inside the push but-
ton lights up
– Set the temperature selector 3
Fully clockwise.
– Set the time at clock 4.
Inform the user that water may drip from the
safety valve whilst the water is being heated
up.
5 Shutting the equipment down
Puul the mains plug
for reasons of frost protection and good hygi-
ene, drain the cylinder if it is taken out of use
for longer periods
Fitting the plug-in connector
The plug-in connectors are equipped with a
retainer with stainless steel serrations and
an O-ring for sealing. In addition, they are
designed with the "Twist and secure" function.
By simply turning the screw cap manually, the
pipe is secured in the connector, and the O-
ring is pushed against the pipe to seal it.
Releasing the connection
Turn the screw cap back until a small gap
appears. Turn the retainer back by hand and
hold it in position. The pipe can now be pulled
out again.
Making the connection
The fitting must be in its released state before
inserting the pipe. In this position, there is a
small gap between the screw cap and fitting
body.
Push the pipe past the O-ring until it bottoms
out inside the connector. Tighten the screw
cap unit it meets the casing. This presses
the O-ring against the pipe and secures the
connector.
Gap between the screw
cap and the casing
