ambient temperature is again below the permissible temperat-
ure value, the electric emergency/auxiliary heater continues
DHW heating.
Ambient temperatures above the application limit
If the upper application limit is exceeded, the safety equipment
switches the compressor off. The electric emergency/auxiliary
heater takes over the DHW heating for a period of 60minutes.
After this period, the application limit is checked again. If the
ambient temperature is again above the permissible temperat-
ure value, the electric emergency/auxiliary heater continues
DHW heating.
3.4 Safety instructions
Injury
– If the insulation or individual components are damaged,
there is a risk of fatal electrocution. If such damage has oc-
curred, switch off the power supply and arrange a repair.
– The work described in this manual requires specialised
knowledge of electrical engineering and heating techno-
logy. If the work described is carried out without the appro-
priate expertise, this may result in injury. Only qualified
contractors are permitted to work on the appliance.
– The water in the DHW cylinder can be heated to temperat-
ures in excess of 60°C. There is a risk of scalding at outlet
temperatures in excess of 43°C. Ensure you do not come
into direct contact with the outflowing water or components
that have heated up.
– If refrigerant escapes in high concentrations, it can cause
symptoms such as headaches, loss of consciousness or ir-
regular heartbeat. Avoid direct skin contact and do not in-
hale the vapours. Ventilate the rooms affected. Please note
that refrigerants are odourless.
– The refrigerant is highly flammable. Keep the installation
site clear of heat, sparks and other ignition sources, in par-
ticular in the event of a leak. The appliance may only be
stored in rooms without a permanent source of ignition
(e.g. naked flame, switched-on gas appliance, electric
heater).
– In their original condition, electrical components are not
sources of ignition (e.g. hot surface, sparking or arcing) and
cannot ignite the refrigerant in the event of a leak. Only use
the recommended original spare parts.
– Unsuitable spare parts and accessories may jeopardise user
and product safety. Only use original spare parts and ori-
ginal accessories.
– Safe use is not guaranteed if installation of the appliance is
incomplete. Only operate the appliance once installation is
complete. Only operate the appliance with the casing and
cover closed.

– WARNING: If the hot water unit is not used for two or more
weeks, an amount of highly flammable hydrogen gas may
accumulate in the water tank. To dissipate this gas safely, it
is recommended that a hot tap be turned on for several
minutes or until discharge of gas ceases. Use a sink, basin
or bath outlet, but not a dishwasher, clothes washer or
other appliance. During this procedure, there must be no
smoking, open flame or any electrical appliance operating
nearby. If hydrogen is discharged through the tap, it will
probably make an unusual sound as with air escaping.
Property damage, consequential losses, environmental
pollution
– Poor air quality can damage the appliance. Keep the appli-
ance installation site free from air contaminated with oil or
salt (chloride). Keep the installation site free from corrosive
and explosive substances. Avoid contaminating the installa-
tion site with dust, hairspray or substances containing
chlorine or ammonia.
– If the air supply is restricted, the operational reliability of
the appliance cannot be guaranteed. Never cover the appli-
ance.
– The appliance may be damaged if the DHW cylinder is
empty and the appliance is switched on. Only operate the
appliance when the DHW cylinder has been filled.
– Hoses and insulation may be damaged if laid incorrectly.
Avoid kinking or excessively compressing hoses and insula-
tion.

The appliance is designed to supply DHW to multiple draw-off
points.
Function
There is a closed circuit within the heat pump which contains
refrigerant.
– The heat pump extracts heat from the ambient air, which is
transferred to the refrigerant in the refrigerant circuit inside
the evaporator.
– The evaporator heats the refrigerant further so that it
changes from a liquid to a gaseous state.
– The compressor draws in the gaseous refrigerant and com-
presses it. This increase in pressure raises the refrigerant
temperature.
– In the downstream condenser, the refrigerant then transfers
heat to the DHW cylinder. The refrigerant changes to a li-
quid state.
– The liquid refrigerant flows through an expansion valve,
which reduces the pressure and temperature of the refri-
gerant.
– The cycle begins again.
– When a DHW draw-off point is opened, cold incoming water
forces the domestic hot water out of the appliance.

The lower the temperature of the intake air and the higher the
selected set temperature, the longer the heat-up time. The heat-
ing output of the heat pump drops and the demand for electrical
energy increases.
Appliance design
The heat pump unit is located in the upper section of the heat
pump.
The heat pump is controlled electronically.
Subject to the power supply and your draw-off patterns, the
heat pump automatically heats water to the selected set temper-
ature.
The DHW cylinder is located in the lower section of the heat
pump. To protect against corrosion, the DHW cylinder is coated
internally with special enamel and equipped with a protective
anode.

4.3.2 DHW heating
The appliance is equipped with two temperature sensors.
– The cylinder top sensor captures the water temperature in
the upper section of the cylinder.
– The integral sensor determines the average cylinder tem-
perature.
1
2
D0000050335
1 Cylinder top sensor 2 Integral sensor
The MyStiebel app displays the temperature in the upper section
of the cylinder, which is captured by the cylinder top sensor. The
control unit additionally uses the average cylinder temperature
captured by the integral sensor.
DHW heating starts in the following cases:
– The actual temperature determined by the cylinder top
sensor is ≥3K lower than the set temperature.
– The available mixed water amount drops to the percentage
share of the maximum mixed water amount set in the para-
meter "charge level". The available mixed water amount is
calculated on the basis of the average cylinder temperature.
The mixed water amount is only calculated if the water
temperature in the upper and middle section of the cylinder
is higher than 40°C (±0.5K).
4.3.3 Defrost monitoring
The appliance is equipped with an electronic defrost monitor.
Low air intake temperatures may result in the formation of hoar
frost on the evaporator depending on the air humidity and DHW
temperature.
The appliance starts the defrosting process when the air intake
temperature and the evaporator temperature fall below the set
limits.
During the defrosting process, DHW heating with the heat pump
(compressor) is interrupted. If the electric emergency/auxiliary
heater was already activated, it remains active.
In the MyStiebel app, it is possible to activate the electric emer-
gency/auxiliary heater to heat the water.
If it is necessary to defrost the evaporator, the heat-up pro-
cesses will take longer.
The appliance switches off the compressor during the defrosting
process. The fan continues to run.
The defrosting process is shown in the MyStiebel app until it fin-
ishes.
4.3.4 Frost protection/ holiday
The operating modes must be activated in order to use the func-
tions.
The appliance activates a frost protection function if the DHW
temperature is below a limit value (<8°C).
The appliance heats the water with the heat pump. If the tem-
perature falls below the application limit or the temperature in
the DHW cylinder drops, the electric emergency/auxiliary heater
is switched on.
The heat pump and electric emergency/auxiliary heater switch
off once the DHW temperature is above the limit value again.
4.3.5 Electric emergency/auxiliary heater
Water is normally heated by the heat pump of the appliance.
If the temperature falls below or exceeds the application limits,
the electric emergency/auxiliary heater takes over DHW heating
to the set temperature. Heat pump operation is interrupted.
Every hour, the control unit once again checks whether the ap-
plication limits are being adhered to.
Once the appliance is operating within the application limits
again, the electric emergency/auxiliary heater switches off and
DHW heating continues with the heat pump.

1 Electric emergency/auxili-
ary heater
Emergency heating mode
Emergency heating mode can be used to start up the electric
emergency/auxiliary heater (see chapter
Activating/deactivating
emergency heating mode [}18]
).
Rapid/comfort heat-up
If a one-off demand for extra hot water arises, you can activate
this function (see chapter
Activating/deactivating rapid heat-up
[}16]
).
4.3.6 External signal transmitter
External signal transmitters can be integrated via the built-in
contact input, e.g. a photovoltaic system to make use of solar
power generated on site.
4.3.7 External switching device
The device can be operated with an external switching device
that interrupts the power supply to the appliance. This can be,
for example:
– External time switch
– Switched socket
en
Transportation (qualified contractors)
8 | SHP-O Plus www.stiebel-eltron.com
– Energy management system
– Signal from the power supply utility (EVU) that interrupts
the power supply
4.3.8 Runtime-dependent rapid heat-up
Only use the runtime-dependent rapid heat-up function if in-
structed to do so by us. Activating this function is likely to affect
the efficiency of the appliance and can lead to unnecessarily
higher energy consumption and higher operating costs.
The appliance offers the option of runtime-dependent rapid
heat-up. If the selected set temperature is not reached by the
heat pump after a user defined period, the appliance switches
on the electric emergency/auxiliary heater in parallel to back up
the heat pump (subject to this function being enabled).
Once the set temperature has been reached, the electric emer-
gency/auxiliary heater is deactivated until the set runtime has
elapsed again following a heat demand. This function is dis-
abled at the factory.

Efficiency
– To keep the pipe runs as short as possible, install the appli-
ance close to kitchens or bathrooms.
– The appliance performance data is calculated according to
the relevant standards, using the intake temperature spe-
cified in the data table. Below this temperature the appli-
ance efficiency and output decrease. The heat-up time is
extended.
Recirculation air mode
– The appliance must not impair the operation of other appli-
ances in the installation room.
– Other appliances in the installation room must not interfere
with operation of the heat pump.
– You can improve the efficiency of the appliance by utilising
the waste heat from other appliances to heat the domestic
hot water, e.g. boilers, tumble dryers or freezers.
Sound emissions
– The sound emissions are louder on the air intake and air
discharge sides of the appliance than on the closed sides.
Do not direct the air intake or air discharge towards noise-
sensitive rooms of the house, e.g. bedrooms.

SG Ready
"SGReady" is a trademark of the Bundesverband Wärmepumpe
e.V. (German Heat Pump Association) and denotes a property of
heat pumps whose control technology enables them to be integ-
rated into a smart power grid (SG = Smart Grid).
D0000043557
The device has two contact inputs (input 1 = XD14/1, input 2 =
XD14/2) for coupling to an inverter or a ripple control receiver.
This enables you to integrate your connected heat pump into an
intelligent power supply. Alternatively, you can utilise the device
to increase the proportion of self-generated photovoltaic power.
Depending on the switching, your device can execute the follow-
ing operating modes:
SG Ready Status1 (operating state 1)
– Input 1 = XD14/1, input 2 = XD14/2
– Switch input 1 = 0, switch input 2 = 1
– Voltage between XD14/2 and XD14/N
– Standby temperatures as specified in the operating and in-
stallation instructions for the connected heat pump
(standby).
– Frost protection is assured.
– The "Standby" symbol flashes slowly.
SG Ready Status2 (operating state 2)
– Input 1 = XD14/1, input 2 = XD14/2
– Switch input 1 = 0, switch input 2 = 0
– Automatic/ Programmed mode as specified in the operat-
ing and installation instructions for the connected heat
pump.
SG Ready Status3 (operating state 3)
– Input 1 = XD14/1, input 2 = XD14/2
– Switch input 1 = 1, switch input 2 = 0
– Voltage between XD14/1 and XD14/N
– Forced operation with increased value for the DHW temper-
ature (set temperature 2) (configuration in the MyStiebel
app).
SG Ready Status4 (operating state 4)
– Input 1 = XD14/1, input 2 = XD14/2
– Switch input 1 = 1, switch input 2 = 1
– Voltage between XD14/1 and XD14/N and voltage between
XD14/2 and XD14/N
– Immediate control of the maximum value (fixed) for the
DHW temperature (set temperature 2) including operation
of electric emergency/auxiliary heater (configuration in the
MyStiebel app)
An energy management system or the power supply utility (PSU)
can control the cited operating states, e.g.for load redistribu-
tion in the event of a power shortage.
If SG Ready status 1 or 4 is active, the symbol for the "SG Ready"
function flashes on the appliance.
When SG Ready Status 3 is activate, the symbol for the "SG
Ready" function lights up on the appliance.
Connecting an external signal transmitter
In order to control the appliance using an external signal, you
must connect a separate electric cable inside the appliance.

The relay in the inverter or photovoltaic system must meet the
following requirements:
– Potential-free relay (240VAC, 1A) with N/O contact
– Adherence to safety regulations and standards for safety ex-
tra low voltage
– The switching output must be programmed such that the
relay closes or opens if certain limits are exceeded or un-
dershot (e.g.inverter output level, feed-in to the power

The inverter power feed is usually located at a central distribu-
tion point (e.g. in the main fuse box).
Closing and locking the control panel
u Replace the control panel cover.
u Lock the control panel.
8.3 Initial start-up
u Switch the mains power supply on.
u Check whether the heat pump heats the water.
ð During the heat-up process, expansion water will drip
from the safety valve.
8.4 Recommissioning
If the heat pump is switched off by an interruption to the power
supply and the power supply is subsequently restored, no meas-
ures are required to restart it.
Following an interruption to the power supply, compressor op-
eration remains blocked for at least one minute. The control
delays the electrical start-up by one minute, during which the
appliance initialises. If the compressor subsequently fails to
start, it may be locked out by additional safety devices (motor
overload relay and high pressure switch). This block should lift
after 1to 10minutes.
The heat pump will have saved the parameters most recently set
and will continue operating with them.

14.1 Resetting the high limit safety cut-out
If the temperature of the cylinder water exceeds 89°C, the high
limit safety cut-out switches off the electric emergency/auxiliary
heater. These high temperatures can be caused by a defective
heating element or a fault in the electronics, for example.
The high limit safety cut-out also responds in the event of frost.
u Remove the cause of the fault.
u Isolate the appliance from the power supply.

14.2 Safety pressure limiter
If the pressure in the refrigerant circuit is too high, the safety
pressure limiter interrupts the power supply to the compressor
until the pressure in the refrigerant circuit falls below the set
limit value. If the safety pressure limiter responds 5 times in
5hours, compressor operation is blocked.
u Remove the cause of the fault.
ð The appliance carries out pressure equalisation. This
process takes a few seconds.
u When the pressure equalisation process is complete, unlock
the heat pump in the Servicewelt app.

17 Maintenance and inspection (quali-
fied contractors)
The area around the unit should be dry, clean and well ventil-
ated. Clean the heating exchanger regularly to maintain good
heat exchange and conserve energy .
The operation pressure of the refrigerant system should only be
serviced by a certified technician.
You should discharge the water at the bottom of water tank (in-
let nozzle cold water) if the unit will not be used for an extended
period of time.
You should check the unit thoroughly and fill the system with
water fully before using it for the first time after a prolonged
period of no usage.
Checks to the area
Prior to beginning work on systems containing flammable refri-
gerants, safety checks are necessary to ensure that the risk of
ignition is minimised. For repair to the refrigerating system, the
following precautions shall be complied with prior to conduct-
ing work on the system.
Work procedure
Work shall be undertaken under a controlled procedure so as to
minimise the risk of a flammable gas or vapour being present
while the work is being performed.
General work area
All maintenance staff and others working in the local area shall
be instructed on the nature of work being carried out. Work in
confined spaces shall be avoided. The area around the work-
space shall be sectioned off. Ensure that the conditions within
the area have been made safe by control of flammable material.
Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant de-
tector prior to and during work, to ensure the technician is
aware of potentially flammable atmospheres. Ensure that the
leak detection equipment being used is suitable for use with
flammable refrigerants, i.e. non-sparking, adequately sealed or
intrinsically safe.
Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equip-
ment or any associated parts, appropriate fire extinguishing
equipment shall be available to hand. Have a dry powder or CO
2
fire extinguisher adjacent to the charging area.
No ignition sources
No person carrying out work in relation to a refrigeration sys-
tem which involves exposing any pipe work that contains or has
contained flammable refrigerant shall use any sources of igni-
tion in such a manner that it may lead to the risk of fire or ex-
plosion. All possible ignition sources, including cigarette
smoking, should be kept sufficiently far away from the site of in-
stallation, repairing, removing and disposal, during which flam-
mable refrigerant can possibly be released to the surrounding
space. Prior to work taking place, the area around the equip-
ment is to be surveyed to make sure that there are no flam-
mable hazards or ignition risks. No Smoking signs shall be dis-
played.
Ventilated area
Ensure that the area is in the open or that it is adequately vent-
ilated before breaking into the system or conducting any hot
work. A degree of ventilation shall continue during the period
that the work is carried out. The ventilation should safely dis-
perse any released refrigerant and preferably expel it externally
into the atmosphere.
Checks to the area
Prior to beginning work on systems containing flammable refri-
gerants, safety checks are necessary to ensure that the risk of
ignition is minimised. For repair to the hot-water system, the
following precautions shall be complied with prior to conduct-
ing work on the system.
Checks to the refrigeration equipment
Where electrical components are being changed, they shall be
fit for the purpose and to the correct specification. At all times
STIEBEL ELTRON maintenance and service guidelines shall be
followed. If in doubt consult the STIEBEL ELTRON technical de-
partment for assistance. The following checks shall be applied to
installations using flammable refrigerants:
– The charge size is in accordance with the room size within
which the refrigerant containing parts are installed;
– Marking to the equipment continues to be visible and
legible. Markings and signs that are illegible shall be cor-
rected.
Checks to electrical devices
Repair and maintenance to electrical components shall include
initial safety checks and component inspection procedures. If a
fault exists that could compromise safety, then no electrical sup-
ply shall be connected to the circuit until it is satisfactorily dealt
with. If the fault cannot be corrected immediately but it is ne-
cessary to continue operation, an adequate temporary solution
shall be used. This shall be reported to the owner of the equip-
ment so all parties are advised.
Initial safety checks shall include:
– That capacitors are discharged: this shall be done in a safe
manner to avoid possibility of sparking;
– That there no live electrical components and wiring are ex-
posed while charging, recovering or purging the system;
Maintenance and inspection (qualified contractors)
www.stiebel-eltron.com SHP-O Plus | 23
– That there is continuity of earth bonding.
Repairs to sealed components
Sealed electrical components should not be repaired. In the
event of a fault, these components must be replaced with ori-
ginal spare parts from STIEBEL ELTRON.
Repair to intrinsically safe components
Do not apply any permanent inductive or capacitance loads to
the circuit without ensuring that this will not exceed the per-
missible voltage and current permitted for the equipment in
use.
Intrinsically safe components are the only types that can be
worked on while live in the presence of a flammable atmo-
sphere. The test apparatus shall be at the correct rating.
Replace components only with parts specified by STIEBEL EL-
TRON. Other parts may result in the ignition of refrigerant in the
atmosphere from a leak.
Cabling
Check that cabling will not be subject to wear, corrosion, ex-
cessive pressure, vibration, sharp edges or any other adverse
environmental effects. The check shall also take into account the
effects of aging or continual vibration from sources such as
compressors or fans.
Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition be
used in the searching for or detection of refrigerant leaks. A hal-
ide torch (or any other detector using a naked flame) shall not
be used.
Leak detection methods
The following leak detection methods are deemed acceptable
for systems containing flammable refrigerants.
Electronic leak detectors shall be used to detect flammable refri-
gerants, but the sensitivity may not be adequate, or may need
re-calibration. (Detection equipment shall be calibrated in a re-
frigerant-free area.) Ensure that the detector is not a potential
source of ignition and is suitable for the refrigerant used. Leak
detection equipment shall be set at a percentage of the LFL of
the refrigerant and shall be calibrated to the refrigerant em-
ployed and the appropriate percentage of gas (25% maximum)
is confirmed.
Leak detection fluids are suitable for use with most refrigerants
but the use of detergents containing chlorine shall be avoided
as the chlorine may react with the refrigerant and corrode the
copper pipe-work.
If a leak is suspected, all naked flames shall be removed/ extin-
guished.
If a leakage of refrigerant is found which requires brazing, all of
the refrigerant shall be recovered from the system, or isolated
(by means of shut off valves) in a part of the system remote from
the leak. Oxygen free nitrogen (OFN) shall then be purged
through the system both before and during the brazing process.
Removal and evacuation
When breaking into the refrigerant circuit to make repairs or for
any other purpose conventional procedures shall be used. How-
ever, it is important that best practice is followed since flam-
mability is a consideration. The following procedure shall be ad-
hered to:
– Remove refrigerant;
– Purge the circuit with inert gas;
– Evacuate;
– Purge again with inert gas;
– Open the circuit by cutting or brazing.
The refrigerant charge shall be recovered into the correct recov-
ery cylinders. The system shall be "flushed" with OFN to render
the unit safe. This process may need to be repeated several
times. Compressed air or oxygen shall not be used for this task.
Flushing shall be achieved by breaking the vacuum in the sys-
tem with OFN and continuing to fill until the working pressure is
achieved, then venting to atmosphere, and finally pulling down
to a vacuum. This process shall be repeated until no refrigerant
is within the system.
When the final OFN charge is used, the system shall be vented
down to atmospheric pressure to enable work to take place. This
operation is absolutely vital if brazing operations on the pipe-
work are to take place.
Ensure that the outlet of the vacuum pump is not close to any
potential ignition sources and that ventilation is available.
Labelling
Equipment shall be labelled stating that it has been decommis-
sioned and emptied of refrigerant. The label shall be dated and
signed. Ensure that there are labels on the equipment stating
the equipment contains flammable refrigerant.
Recovery
When removing refrigerant from a system, either for servicing
or decommissioning, it is recommended good practice that all
refrigerants are removed safely.
When transferring refrigerant into cylinders, ensure that only
appropriate refrigerant recovery cylinders are employed. Ensure
that the correct number of cylinders for holding the total system
charge is available. All cylinders to be used are designated for
the recovered refrigerant and labelled for that refrigerant (i.e.
special cylinders for the recovery of refrigerant). Cylinders shall
be complete with pressure relief valve and associated shutoff
valves in good working order. Empty recovery cylinders are
evacuated and, if possible, cooled before recovery occurs.
The recovery equipment shall be in good working order with a
set of instructions concerning the equipment that is at hand and
shall be suitable for the recovery of flammable refrigerants. In
addition, a set of calibrated weighing scales shall be available
and in good working order. Hoses shall be complete with leak-
free disconnect couplings and in good condition. Before using
the recovery machine, check that it is in satisfactory working or-
der, has been properly maintained and that any associated elec-
trical components are sealed to prevent ignition in the event of a
refrigerant release. Consult manufacturer if in doubt.
The recovered refrigerant shall be returned to the refrigerant
supplier in the correct recovery cylinder, and the relevant Waste
Transfer Note arranged. Do not mix refrigerants in recovery
units and especially not in cylinders.
If the compressor or compressor oil are to be removed, ensure
that they have been evacuated to an acceptable level to make
certain that flammable refrigerant does not remain within the
lubricant. The evacuation process shall be carried out prior to
returning the compressor to the suppliers. Only electric heating
to the compressor body shall be employed to accelerate this
process. When oil is drained from a system, it shall be carried
out safely.
Decommissioning
Before carrying out this procedure, it is essential that the tech-
nician is completely familiar with the equipment and all its de-
tail. It is recommended good practice that all refrigerants are
en
Maintenance and inspection (qualified contractors)
24 | SHP-O Plus www.stiebel-eltron.com
recovered safely. Prior to the task being carried out, an oil and
refrigerant sample shall be taken in case analysis is required
prior to re-use of reclaimed refrigerant. It is essential that elec-
trical power is available before the task is commenced.
u Become familiar with the equipment and its operation.
u Isolate system electrically.
u Before attempting the procedure ensure that:
– Mechanical handling equipment is available, if required, for
handling refrigerant cylinders;
– All personal protective equipment is available and being
used correctly;
– The recovery process is supervised at all times by a compet-
ent person;
– Recovery equipment and cylinders conform to the appropri-
ate standards.
u Pump down refrigerant system, if possible.
u If a vacuum is not possible, make a manifold so that refri-
gerant can be removed from various parts of the system.
u Make sure that cylinder is situated on the scales before re-
covery takes place.
u Start the recovery machine and operate in accordance with
manufacturer's instructions.
u Do not overfill cylinders. (No more than 80 % volume liquid
charge).
u Do not exceed the maximum working pressure of the cylin-
der, even temporarily.
u When the cylinders have been filled correctly and the pro-
cess completed, make sure that the cylinders and the
equipment are removed from site promptly and all isolation
valves on the equipment are closed off.
Recovered refrigerant shall not be charged into another refri-
geration system unless it has been cleaned and checked.
Charging procedures
In addition to conventional charging procedures, the following
requirements shall be followed.
– Ensure that contamination of different refrigerants does not
occur when using charging equipment. Hoses or lines shall
be as short as possible to minimise the amount of refriger-
ant contained in them.
– Cylinders shall be kept upright.
– Ensure that the refrigeration system is earthed prior to
charging the system with refrigerant.
– Label the system when charging is complete (if not already).
– Extreme care shall be taken not to overfill the refrigeration
system.
– Prior to recharging the system it shall be pressure tested
with OFN. The system shall be leak tested on completion of
charging but prior to commissioning. A follow up leak test
shall be carried out prior to leaving the site.
