General information
Introduction
General information prior to installation
T
he following documents are supplied with the unit:
• Installation instructions/Software instructions
• User manual
• Wiring diagram
The instructions can be downloaded from the Nilan website: http://www.nilan.dk/en-gb/frontpage/
download
If you have further questions on unit installation after reading the instructions, contact your nearest
Nilan distributor, who can be found on www.nilan.dk/en-gb/frontpage/download/dealers.
The purpose of these instructions is to give the installer advice on correct installation and maintenance
of the unit.
The unit must be started up immediately after installation and connection to the duct system. In
periods where the ventilation system is not in operation, humid air from the rooms may penetrate into
the ducts and form a condensate. The condensate may leak out of the valves and damage furniture and
floors. In addition, condensate may form inside the unit, damaging the unit's electronics and fans.
The unit is supplied fully tested and ready for operation.
Unit type
Product description
C
ompact P AIR is a ventilation unit with an integral heat exchanger that also produces hot water for
domestic use as well as central heating via an air/water heat pump.
Compact P is designed for air flows of up to 275 m 3 /h at 100 Pa external counter-pressure. Compact P
XL can handle air flows up to 430 m 3 /h at 100 Pa external counter-pressure.
The ventilation part draws the humid, vitiated air out of the dwelling via the bathroom, WC, kitchen and
utility room and introduces fresh air into the habitable rooms, i.e. living room, bedrooms and office. The
cold outdoor air is heated up in the heat exchanger (heat recovery) by the warm extract air.
In addition to a (counterflow) heat exchanger, Compact P has an integral heat pump. The heat pump
uses the heat remaining in the extracted air following heat recovery in the heat exchanger to produce
hot water. In case of high hot water consumption, there is a 1.5 kW electric supplement heater in the
hot water tank, which can also be used to heat the water.
In the winter, the heat pump can be used to heat the supply air (inlet air) during periods in which no
domestic hot water is being produced. The supply air can be heated to 34 °C.
As it is a reversible heat pump, it can be used in summer to cool the supply (inlet) air. Compact P is able
to cool the supply air by up to 10 °C. However, it will not function as an air conditioning unit, as it
operates with a relatively low air change rate. Cooling of the supply air removes humidity from the
indoor air, providing good comfort for persons in the dwelling, even if the indoor temperature is high.
Compact P is able both to provide cooling and produce domestic hot water, so it could be said that the
cooling of the supply air is "free of charge".
7
The energy-efficient and low-noise AIR air/water heat pump heats the home via floor heating or low-
emperature radiators. It extracts energy from the outside air and functions at temperatures as low as
t
-22 ºC. The heat pump has an electrical power supply to help it to function during very cold periods. The
AIR unit has a reversible cooling circuit, which means that it can also be used to cool the home during
the summer, using either the floor heating system or fan coils.
The AIR air/water heat pump can also be used to help produce hot water for domestic use, either by
pre-heating the water in a buffer tank, or directly in a Compact P hot water tank, if bought with a solar
coil.

Accessories
E
lectrical preheating element for frost protection
In longer periods of sub-zero temperatures, the high-efficiency counterflow heat
e
xchanger will ice up. To avoid icing, it is recommended that an electrical
preheating element is mounted.
The preheating element uses very little energy, but ensures efficient heat
recovery without de-icing, thus achieving an overall saving in energy
consumption.
Water heating element incl. regulation
A water heating element can be used to increase supply air temperature to the
d
esired level. It is fitted in the supply air duct and must be connected to the
primary heat supply.
Supplied with a two-way regulating valve, temperature sensor and frost
thermostat.
Electrical heating element
An electric heating element allows the supply air temperature to be raised to the
d
esired level. Electric heating elements are supplied for mounting in the supply
air duct, and are provided with the necessary sensors.
Pollen filter
The unit is supplied as standard with filter sheet.
I
f persons in the dwelling suffer from a pollen allergy, there is an option for
mounting a pollen filter in the outdoor air inlet to minimise the pollen in the
indoor air.
EM box
With an EM box it is possible to divide the extract air between the kitchen and
athroom.
b
If the cooker hood is operating via the unit and is switched on, air extraction from
the bathroom reduces slightly to allow sufficient air for the cooker hood to
extract kitchen fumes.
CO2

Safety group
Safety features
Compact P / Compact P Polar - AIR (English)
The safety group consists of:
T
he safety group, which is made of brass, consists of a stop valve with an integral
non-return valve, a safety valve and drain cock. It can be installed directly
beneath the hot water tank.
During periods with cooling ventilation, hot water in the tank can reach very high
t
emperatures - up to 80 ºC.
A maximum temperature of up to 60 ºC can be set in the control system to
prevent scalding, but active cooling is then limited.
To make full use of the cooling function, scalding protection should be fitted that
mixes hot water with cold to bring the temperature down.
BY NILAN
If a solar panel is used to supplement hot water heating, scalding protection must
be fitted.
Flexible silencing
To facilitate later servicing of the unit, we recommend fitting a flexible
connection between the unit and the duct system.
Nilan's sound damping flexi-hose gives good sound damping both to the duct
system and to roof stacks.
Trolley
A trolley makes it possible to lift the unit of the pallet without physical strain.
T
he same trolley can be moved to wheel the unit around.
SHW hot water tank
If there is a large demand for hot water, a 250 litre hot water tank can be
c
onnected.
The hot water tank is heated by the central heating system’s heat pump and/or
via solar panels.
The water runs from the SHW tank, through the DHW tank in Compact P, before
running into the domestic hot water supply.
15
Installation
Installing the internal unit
Transport into the dwelling
Compact P is supplied in one piece on a pallet, packed in cardboard.
It is fitted at the factory with 4 lifting straps, one for each top corner. This makes it possible to lift in the
unit with a crane. When lifting the units with the supplied straps, these must be at an angle of max. 45°
from the vertical.
Nilan also offers a lifting trolley, with which the unit can be lifted directly off the pallet and into the
building. If the filter box is removed, the unit can be manoeuvred through an ordinary door.
Positioning of unit
ATTENTION
When setting up the unit, consideration must always be given to future servicing and
maintenance.
It must be easy to replace filters, and it must be possible to perform tasks such as removing the
heat exchanger, replacing fans and other components.
ATTENTION
A minimum free space in front of the unit of 60 cm is recommended.
It is important that the unit is level in order to achieve proper run-off from the condensate tray.
The unit should be positioned on a level and vibration-free substrate. In itself, the unit is low-noise and
low-vibration, but even so, account must be taken of possible vibrations which could be transferred to
building parts. We recommend maintaining a minimum 10 mm gap from building parts and other fixed
equipment.
ATTENTION
For noise reasons, it is recommended that the unit is positioned with its rear panel against an
outer wall.
At the lower rear and sides there are punched
areas which can be clipped out.
This avoids the necessity of cutting holes
yourself.
The rear angle iron on the base frame can be
removed, allowing the unit to be pushed up
against the wall, thereby concealing the water
connections.
16
ATTENTION
If a screen is mounted over the Compact P, it must be easy to dismantle this.
Compact P / Compact P Polar - AIR (English) BY NILAN
Installing the external unit
Installation transport of external unit
The external AIR unit is supplied film-wrapped and fastened with straps to a transport pallet.
If ground conditions allow, it is recommended that a lifting truck is used to move it.
ATTENTION
If the AIR unit is lifted in using a crane, please notice that the weight is not evenly distributed at
the front and back.
17
Sound data
The sound from the AIR unit's external unit can be propagated depending on where it is sited relative to
the building and the underlying surface, as well as on other surrounding objects and surfaces.

Compact P / Compact P Polar - AIR (English) BY NILAN
Installing the external unit
The external unit must always be installed on a firm, vertical and vibration-free surface and secured to
some solid material if possible. Account must also be taken of the prevailing wind direction during the
heating season, as the performance of the heat pump will be limited if the external unit is exposed to
strong winds.
A windbreak can be installed if required. However, clearance distances as detailed below must be
observed.
The following horizontal minimum distances to building components etc. must be observed in order to
ensure optimum functioning of the heat pump.
L ≥ 50 cm
L ≥ 40 cm
L ≥ 40 cm
L ≥ 35 cm
If it is wished to install the AIR unit against the building, it is important not to install it close to any
bedrooms due to the noise from the fan.
Locate the AIR unit in such a way that the intake air is drawn from the building's surface. This is
because solar heating of the wall during the day and general heat loss from the building supplies
additional energy to the air, which can then improve the efficiency of the heat pump. If the AIR unit is
located with the extract directed at the wall, this will result in cold and damp air being blown against the
building, adding extra energy to the air.

Condensate drain
During operation, condensate will form in the external unit’s evaporator, and which has to be run off to
a drain. There is a tube measuring xx m connected to the evaporator’s condensation surface which
leads to a drain.
The condensate drain must be insulated against frost, although it is supplied with a 1.5 m heating cable,
which also helps to keep the condensate drain frost-free. The heating cable starts operating at outdoor
temperatures of < 2 ºC.
ATTENTION
The condensate must be directed away in a way that avoids damaging the building.
If draining the condensate off into gravel, it must be ensured that it is run off into frost-free subsoil:
If the external unit is located close to the building, the condensate can be drained into a downpipe.
Remember to install a water trap:

1x230V ~ 50 Hz max. 16A
ATTENTION
It is important that the temperature sensor for the heating element is positioned at least 32 cm
after the preheating element in order to achieve correct regulation.
The T8 outdoor air temperature sensor is positioned before the external preheating element and
connected to the Compact P control system, to allow it to perform regulation via the outdoor air
temperature. If it is not wished to regulate the functions via the outdoor air temperature, T8 may be
deactivated in the software under the frost protection section:
The preheating element has a three-stage safety system against overheating.
1. There is a operating thermostat which regulates the heat and ensures that the supply air
temperature does not fall below -1 °C
2. There is a max. thermostat, which shuts down the preheating element if the temperature rises
above 50 °C
3. There is a manual safety thermostat, which shuts down the preheating element if the
temperature rises above 100 °C
ATTENTION
When mounting the electric preheating element, there must be a safety gap of minimum 15 cm
from any flammable material. The heating element must be insulated with a fire retardant
insulation material, but the cover on the connection box must not be insulated.

Cooker hood and EM box
There are several benefits from connecting the cooker hood to the home’s ventilation system. Firstly,
there is full heat recovery of heat from cooking.
Secondly, the unit is able to provide balance in the ventilation. If the cooker hood does not run via the
ventilation and if the house is new and airtight, use of the cooker hood will create a negative pressure
in the home, minimising the suction effect from the cooker hood and also creating smoke problems, for
instance if a wood-burning stove or open fire is installed and in use. By running the cooker hood via the
unit, the unit can increase the supply air as the volume of extract air from cooker hood operation goes
up. In this way, a balance can be maintained in the home, and the cooker hood will retain its full suction
power.
In the case of ventilation of a large home/building, with more than one bathroom, there may be
problems creating sufficient air capacity for the cooker hood. In these cases, an EM box will be an ideal
addition, as it minimises the extract air from the other high-humidity rooms for the short period that
the cooker hood is in use, and in this way ensures sufficient air for extraction via the cooker hood.
ATTENTION
If the cooker hood is connected to the ventilation system, it is important that it is fitted with a
good grease filter and that this can be regularly cleaned.

ser selection 1
It is possible to override the unit's functions via an external signal from a potential free contact
The User selection function can be used for many purposes, e.g. in the case of a wood burning stove or
open fire. Initial settings of the ventilation system should be set up with a slight underpressure, so that
humidity in the air is not forced into the building elements. This is of course a disadvantage when
lighting a wood burning stove, as smoke will enter the room. You can use a dry contact to configure one
of Fan stages (e.g. fan stage 4) to run with a slight over-pressure instead, to push the smoke through
the chimney as intended.

User selection 2 has the higher priority and is therefore used for cooker hood operation if a cooker
hood is connected to the ventilation system. Normally fan speeds 3 or 4 are set for cooker hood
operation. The output signal can be used for connecting an EM box or external damper which is to
assume a particular setting during cooker hood operation.

Connecting EHD damper
To conduct outdoor air down through a geothermal pipe in the ground makes good sense. The air is
heated during the winter and cooled in the summer by the ground.
But passing outdoor air through such a geothermal system may not be the best idea in the spring and
autumn, but taking it directly through a roof vent is recommended.
The CTS700 control system has a built-in function that measures whether the geothermal pipe or roof
vent provides the best option for air intake.
It measures the outdoor temperature during a stabilising period from the geothermal pipe and roof
vent respectively. The measurement indicates where it is best to direct the outdoor air. CTS700 sets
the EHD damper to the best option, and continues ventilation for a set period, referred to in the
program as holding time.
The EHD damper is connected via relay 7 and set on the display menu item: Ventilation / Frost
protection or de-icing / Frost protection.

Active cooling function
he AIR unit has a reversible cold circuit, which means that it can be used to actively cool the home,
T
using either the underfloor heating system or fan coils.
Active cooling using the underfloor heating
There is an external temperature sensor connected to digital input 10. When the contact is closed, the
AIR unit goes into cooling mode and cools the home down to a pre-set value. When the contact is broken
again, the AIR unit returns to normal operation.
The external temperature sensor often has an infra-red sensor, which measures the temperature of
the floor and stops the cooling function before condensation forms on the floor.
Active cooling using fan coils
T
here is an external temperature sensor connected to digital input 10. When the contact is closed, the
AIR unit goes into cooling mode and cools the home down to a pre-set value. At the same time, relay
output 10 is activated, which can control a three-way valve so that the water is directed out to fan coils
instead of going into the floor. When the switch is deactivated, the AIR unit returns to normal
operation.

Plumbing installation
Condensate drain, internal unit
Important information
Compact P is supplied with a reinforced 20 mm condensate drain hose with integral water trap.
ATTENTION
The condensate drain should be installed with an even fall of at least 1 cm per m to the nearest
drain. Similarly, the overflow from the safety valve for the cold water supply must be led to a
prominent drain.
ATTENTION
If the unit is assembled outside the climate screen, it is important to secure the condensate
drain against icing. Frost protection of the unit is the installer's responsibility.
The connection of the water trap must be air-tight, otherwise air will be sucked into the unit and
condensate will remain in the unit. This could lead to water damage if the condensate overflows the
condensate tray and from there out of the unit.
After mounting the water trap, its function is tested as follows: Fill the condensate tray with water and
operate the unit at the highest fan speed. Allow it to run for several minutes. Check that there is no
water in the condensate tray when the test is finished (the unit must be connected to the duct system
and the lid must be closed during the test).
The water trap may dry out and thus prevent water escaping from the condensate tray, as air will blow
into the unit. The water trap should therefore be checked at regular intervals, especially in the
summer, and filled with water as necessary.
Must not be cut
- this is a water trap
The water trap is integrated in the hose running from the condensate tray to the drain, and is fitted by
the factory.

against unnecessary heat loss.
All connection nozzles for water have 3/4" thread and are located in the tank bottom.
The tank is also fitted with an electronically-monitored sacrificial anode that automatically displays a
warning on the display when it needs changing.
44
Compact P / Compact P Polar - AIR (English) BY NILAN
CAUTION
Changing the anode when notified on the display is important. Failure to do so can cancel the
guarantee on the hot water tank.
The tank is fitted with a 1.5 kW supplementary electrical heater deactivated by default and activated
via the control panel if required.
ATTENTION
The supplementary heating must not be activated before the water tank is full of water.
Hot water circulation
If wished, hot water circulation can be established by fitting a non-return valve and a circulation pump
for domestic water to the tank's circulation connector (1).
If hot water circulation is not established, the connector must remain closed with the factory-mounted
shut-off plug.
ATTENTION
Hot water circulation can lead to a significant heat loss in the pipes, diverting a good proportion
of the heat pump's output. To avoid this, circulation pipes and the hot water loop must be
insulated with at least 30 mm mineral wool.
It is advisable to set a timer so that the circulation pump is not running constantly.
Solar coil
All Compact P SOL models have integral supplementary coil, see connections list.
The solar coil with a surface area of 0.6 m

ATTENTION
If a solar collector or other heat source is connected to a Compact P model, it is recommended

Softened water
If it is wished to soften water with salt in a Nilan hot water tank, the following must be observed:
• The hardness of the water must be at least -2° dh (proportion of alkaline earths 0,4 mmol/l)
• The conductivity must be between 13 mS/m og 150 mS/m (millisiemens per m)
• The pH value must be between 6.5 and 9.5
• The chlorine content must be under 250 mg Cl/l
If the above criteria are exceeded, the anode current will be too high, the anode will break down too
quickly and the water will begin to smell bad.
CAUTION
Demineralised water (double ion exchange) must not be used as the tank will corrode very
rapidly. Demineralised water is also called totally desalinated water and deionised water.

Insulation of hoses from the outdoor unit
It is important, that the brine hoses between the inside and outside units is well insulated, according to
current standards. This is done to avoid heat loss and achieve good operation.
A detail that is often forgotten is the schrader valve in the outdoor unit. It is very important that it is
also insulated.
CAUTION
If the brine hoses is not well insulated, the AIR heat pump will use significantly more energy and
in worst case, there will not be enough heat in the house.

Safety group
CAUTION
A safety device must be connected to the hot water tank.
When water is heated to 60 °C, it expands by 2%. A pressure tank could burst without a safety valve
keeping excess water out. The safety valve should therefore drip during warming up.
Installation:
The following should be remembered during installation:
a.
The double nut is attached to the water heater’s cold water
pipe so that the arrows are pointing in towards the water
heater (in the direction of the flow). The joint with the water
heater is sealed using a threaded washer.
b.
The joint between the double nut and the system is sealed
using fibre packing.
c.
The rubber ring seal (the O-ring) is fitted to the unit so that it
can function as a seal between the safety valve and the unit in
such a way that the valve is locked.
The end of the overflow pipe must be visible, and it must be able to run out safely via the drain.
ATTENTION
As water expands as it heats up, the safety valve will drip.
ATTENTION
It is up to the installation engineer to tell the customer where the safety valve is and how it
works, and also that it must be regularly checked at least twice a year in order to prevent
incrustation.
49
Safety group with anti-scald protection
The control system contains as standard a temperature limit for domestic hot water of 65 ºC. This
setting prevents users from scalding themselves when the hot tap is turned on.
It also means that when Compact P is in cooling mode, cooling will stop when the domestic hot water
reaches a temperature of 65 ºC.
If the cooling requirement is higher than this, the temperature limit may be raised to 80 ºC, but in this
case an anti-scald device must be mounted under the hot water tank, to prevent users from scalding
themselves when turning on the hot tap.
The anti-scald device mixes hot water with cold water, thus bringing down the temperature and
avoiding scalding. This will extend the period for which Compact P can perform cooling.
CAUTION
If a solar panel is connected to the hot water tank, an anti-scald device must be mounted.

Ventilation mounting
Duct system
Legislation
ATTENTION
All work must be carried out by qualified personnel and in accordance with applicable legislation
and regulations.
Ducts
There are two systems for transporting air round the building.
Spiral tubes
Spiral tubes are metal ducts which are cut to size with an angle grinder, screwed together with bends
and manifolds and laid out in accordance with the working drawing. The duct pipes are typically laid at
the rafter ends and fixed with perforated band or suspended with suspension band. Avoid unnecessary
bends in the ducting.
To avoid noise transmission, where sound is transmitted from room to room, a sound damper must be
mounted in each room.
The ducts must be insulated to avoid heat loss and condensation. In some cases this can be avoided if
the ducts are led through the ordinary insulation or inside the climate screen.
NilAIR tubes
NilAIR tubes are a flexible system which is easy to mount. The tubes are easily cut to size with a hobby
knife and laid according to the working drawing without use of bends and manifolds. A manifold box is
installed after the unit and the tubes run from this out to the various rooms.
With NilAIR tubes it is unnecessary to mount sound dampers in each room, as there is no risk of noise
transmission.
If the tubes are led outside the climate screen they must be insulated to avoid heat loss and
condensation. This is easier than with spiral tubing, as NilAIR tubes are easier to lead through ordinary
insulation.
NilAIR tubes are more flexible than spiral tubing and can therefore be laid in places where ordinary
spiral tubing would be impossible.
Unit
Nilan recommends mounting a flexible connection between the unit and the duct system.
This is to avoid oscillations from the unit being transmitted to the duct system, but also to ease future
servicing where it is necessary to move the unit.
Nilan offers flexible silicing, which, apart from providing a flexible connection between the unit and the
duct system, also dampen the passage of sound from the unit to the duct system.
Flexible silencing are insulated for condensation, but it may be necessary to insulate them further to
meet local requirements for duct system insulation.

Extract air
xhaust valves are mounted in the moisture-generating rooms and strategically placed where they can
E
extract the moisture air most effectively.
Moisture-generating rooms:
• Bathroom
• Toilet
• Kitchen
• Utility room
Supply air
Supply air valves are mounted in habitable rooms and strategically positioned to give the minimum
annoyance. For example, it is not recommended to mount incoming air valves over areas where people
sit, as the air in some cases can be perceived as a draught.
Habitable rooms:
• Living room
• Kitchen-living room
• Bedroom
• Office
Roof stack
The roof inlet and outlet must be positioned and designed to limit pressure fluctuations in the
ventilation system caused by wind impact, and also to prevent access by birds and other animals, and
to ensure that the inlet and closed duct system are kept free of plant parts and foreign objects.
The air inlet must be located to minimise the risk of short-circuiting from the discharge air, having
regard to the prevailing wind direction.
The air inlet should be placed a minimum of 0.5 m above the roof surface, but a minimum of 1 m over
flat black roofs up to the underside of the inlet, to ensure that warm air is not drawn into the building in
the summer. The air inlet should be located on the north or east sides of pitched roofs.
Sound damping should also be mounted between the unit and roof stacks to avoid noise annoyance to
neighbours.

Important information
ATTENTION
For the ventilation system to operate optimally, it is important that initial regulation is carried
out correctly. We recommend having this done by experts.
It is important to measure the total supply (inlet) air and extract (outlet) air. The system must
have a minimum vacuum, i.e. it must draw in more air out than in, to avoid humidity being
pressed into the building construction.
Initial regulation connectors
The unit has initial regulation connectors for measuring the supply air (inlet air) and extract air (outlet
air) volumes.
The graph can be used for roughly setting the main air volume for dry operation without condensation
precipitation, and with approximately the same temperature for outdoor air and extract air.
On the extract air side (outlet air), the pressure drop dP4-3 [Pa] is measured between the connectors
labelled 3 and 4. The air volume qv [m3/h] is read off on the graph.
On the supply air side (inlet air), the pressure drop dP2-1 [Pa] is measured between the connectors
labelled 1 and 2. The air volume qv [m3/h] is read off on the graph.
ATTENTION
The capacity in the pressure drop diagram is based on a dry heat exchanger.
Pressure fall diagram
The measuring connectors are inside behind the
top front panel.

Startup
Central heating
Filling with water
ATTENTION
Before starting the heat pump and the circulation pumps, the central heating circuit connected
to the external unit must first be filled with water
Fill the central heating circuit with water via the feed cock until the correct water pressure is obtained.
It is important that all circuits in the central heating system are open during filling.
ATTENTION
Ordinary water or all common types of antifreeze can be used
There is an automatic vent fitted to the buffer tank, which is activated when filling with water. Check
that the cover on the vent is loose.
There is a Schrader valve fitted to the external unit's top hose connector for venting the connector
between the internal and external units.
Once the central heating circuit has been filled to the correct water pressure, the circulation and heat
pump can be started.
Topping up water
The water pressure must be carefully checked the first few days, even several times a day. It may be
necessary to top up the water in the central heating circuit if the water pressure has dropped.
ATTENTION
It is important that the circulation and heating pump is switched off while topping up the water
The water pressure will stabilise after a few days, after which the checks can be reduced to once a
month.
ATTENTION
If the central heating circuit requires topping up after the start-up phase, it should be checked
for leaks
Check the particle filter
There may be some particulate matter in the central heating circuit, and the heating pump must be
checked immediately after being put into operation.
The filter must be checked several times a day just after installation until it stays clean. With normal
operation, it is enough to check the filter twice a year.
Cleaning the particle filter:
1. Switch off the heating pump on the control panel (Settings: Central heating / Standby functions /
Turn off central heating)
2. Turn the shut-off valve to close off the circulation
3. Remove the filter and rinse until clean
4. Replace the filter
5. Turn the shut-off valve to open up the circulation
6. Switch the heating pump back on

Troubleshooting
Emergency operation
Emergency operation domestic hot water
If an error occurs in the controller or components in the Compact P, and the unit therefore stops, it will
not be able to produce domestic hot water.
If the installer is not able to come right away or the error happens outside the opening hours, and you
therefore cannot contact the installer, there is a possibility to get hot water by setting the unit into
emergency mode.
The button for the emergency operation are located behind the large door
The emergency operation has three settings:
I - Auto: El-supplementation is controlled by the control in the unit
(standard setting)
0 - Off: El-supplementation is off and cannot be turned on again by
the control in the unit
II - Manuel: El-supplementation is turned on, and cannot be turned
off by the control in the unit (Don´t turn it on if there is no water in
the tank)
60
CAUTION
In manual operation, the water temperature can achieve 75 °C, which can cause scalding, if you
are not careful when you open the hot water.
