Congratulations
Congratulations on the purchase of your new CTC
domestic hot water heat pump. You will with no doubt
be pleased with this quality product.To ensure the
best performance and safety from this product, we
recommend you to read the instructions carefully. These
instructions contain the information you need to install
and use your new heat pump.
The heat pump normally covers a family’s need for hot
water throughout the year. CTC EcoWater is equipped
with a built in coil for additional heat from an external
boiler, solar panels, etc.
Information for the installer
This manual should be read carefully before installation.
It contains all information needed for the installation.
Consider standards and local regulations regarding
water installation before taking the product into use.
Special consideration must be taken to water qualities
with larger amounts of for example; limestone, ochre
and dirt particles.
Before the first start check that the system is filled
with water and has been vented. Confirm that all
connections are screwed tight.
At the first start, or when the tank has been emptied,
there must be an operating time of 8 to 10 hours at an
air temperature of 15 °C to reach a water temperature
of 45-55 °C.
Basic heating principle
The heat pump operates on the air to water principal;
i.e. the air is drawn through an evaporator and cooled.
In the compressor the thermal energy of the air is
transformed to a higher temperature and through a heat
exchanger transferred to the water in the boiler.

1.4 Heat pump principle
The picture below describes the heat pump principle.

9CTC EcoWater
English
2. Installation
The heat pump is delivered complete and preset from factory (electrical
connection may be adjusted to fit local standards). The heat pump should
be installed as close as possible to the existing hot water conduit to minimize
the energy losses.
The place of installation must be in level. Small irregularities can be adjusted
by the feet. When filled the heat pump weighs approx. 465 kg. The place for
the installation must stand a corresponding load.
NOTE: Complementary rules in the building regulations must be observed.
2.1 Air ducts
The air can be taken from the room where the heat pump is placed, or
from another room, or from outside. In these cases the heat pump can be
equipped with duct connections, both at the air inlet and the air outlet. The
air pipe must be insulated to avoid condensation. The air inlet (2) and the air
outlet (1) are located at the top of the heat pump. No connections for the air
are needed if air from the room where the heat pump is placed will be used.
The duct connections are intended for ø160 mm ducts.
If ducts are used pressure losses has to be considered. Fan speed has
to be set on high speed (for fan settings see chapter 4 - control system).
If ø160 mm ducts are used the maximum length is approximately 3 meter
(2 x 90°-bends included). If longer ducts are needed a ø200 mm duct
can be used to reach distances up to 7 meters (2 x 90°-bends included).
If more bends are needed the maximum distance has to be reduced by
approximately 500 mm per 90°-bend.

2.2 Domestic hot water
When connecting the hot water please consider the piping material and
water quality to avoid problems with corrosion.
Pipes of Galvanized Steel
One of the major causes of damage to the water system is internal corrosion
of hot water pipes in galvanized steel systems. Normally fittings are most
vulnerable to internal corrosion. Dissolved copper in the water from copper
pipes in the system, increases the risk of corrosion. Considering the rule that
copper should follow galvanized steel in the water flow direction will reduce
the risk. In some installations reflux can occur and thus increasing the risk of
corrosion due to higher copper content in the water.
Pipes of Copper
Copper is usually fully resistant to corrosion in water, but as all other
materials, it has its limitations. Internal corrosion of copper due to turbulence
corrosion is a frequent cause of damages. This applies particularly in bends.
Turbulence corrosion occurs when the speed of the water is between 1,2 to
1,5 m/s and the quality of the water is adverse.
2.3 Circulation connection
Circulation of hot water will increase energy losses and installed piping and
connections must be well insulated. Circulating pump must not be too large,
use any variable pump type or a flow control valve.
2.4 Insulating the connections
All pipes must be insulated to prevent heat loss. If the heating coil is not
used it must be blinded and insulated.
2.5 Connection example for boiler/
solar
Heat pump status: “HP+Boil”.
When the temperature is below Tmin -1 °C the supplementary heating starts.
The supplementary heating stops when the temperature is above Tmin +1°C
Tmin 35 °C ensures 35 °C domestic water, even if the heat pump cannot
provide enough energy.

2.6 System installation
Installations of water should be carried out in accordance with the present
standards concerning installation of water. In accordance with the present !Never start the
heat pump unless it
is filled with water.
rules the coldwater connection should be provided with a drain valve, a
safety valve and an adjustable retaining valve. The valves are not standard
equipment.
Safety valve, check valve, drain
The heat pump installation must be equipped with a double check valve
and safety valve on the cold water supply line. This is to ensure that hot
water from the tank is not leaking into the cold water system and to release
pressure when the tank is heated. From the evaporator in the heat pump
there will be condensation water. The amount is depending on air humidity.
The safety valve and the condensation connection should be connected to a
drain to avoid leakage. For the specification of pipe connections - please see
the dimensional sketch ”Technical data”.
To maintain your cylinder for safety there is a requirement to check the
pressure relief valve 2-3 times yearly. To do this, the valve needs to be
turned clock wise half a turn until the valve clicks and closes. It is normal for
water to be released when this action is carried out” If water continues to
release after this test has been carried out the valve is faulty and requires
replacement.
To avoid injuries (scalding) from high water temperatures it is recommended
to install a thermostatic mixing valve on the hot water outlet. At normal
operation the temperature will not reach levels where scalding is a risk. If a
failure occurs during normal heating temperatures up to 70 °C is possible
before the safety thermostat will stop the immersion heater, otherwise the
immersion heater cuts out at 80 °C. If the safety thermostat cuts, it has to be
reset manually.
In order to avoid noise in the piping system it is recommended to use
approved couplings when connecting the heat pump. The heat pump can be
installed both stand alone and as a part of an existing system. When the tank
is filled during the startup it is necessary to bleed in order to get it filled.
The time needed to raise the water temperature from 10 °C to 45-55 °C is
between 8 and 10 hours at an ambient temperature of 15 °C.

2.7 Supplementary heating
If the performance of the heat pump is not sufficient due to high hot water
use or low ambient temperatures supplementary heating can be used. An
immersion heater is integrated in the product and can be activated in the
control system by choosing HP+EL in the menu "Heat pump". Also external
boilers or solar can be connected to the product (model 301 and 302) via
the internal coil. For this alternative HP+Boil is set in the menu. For electrical
connections and relay outputs see the wiring diagram. The immersion heater
has a built is operational and safety thermostat set at 75/85 °C. With an
external boiler or solar consider the maximum allowed temperature of 75 °C.
When activated, the control system will start the supplementary heating when
the water temperature is 1 degree below Tmin or lower and close it when the
temperature is 1 degree above Tmin.
2.8 Hot water production
Heating of domestic water can be made using the heat pump, immersion
heater and/or boiler/solar. Immersion heater, boiler and solar are described as
supplementary heating. Energy sources are selected in the control system.
They can be selected individually or together (boiler and immersion heater
cannot be chosen at the same time).
Temperature setting range: from 5 °C to Tmax °C. Tmin and Setpoint can be set
independently. A normal setting would be Tmin = 35 °C and setpoint 45 °C to 55
°C. Setpoint is achieved with the heat pump if allowed. If no heat pump is
selected it is achieved with the supplementary heating. Tmin is achieved with
heat pump and supplementary heating, if selected.
The heat pump runs with a hysteresis of (+)1 – (-)3 K for the setpoint. The
supplementary heating runs with a hysteresis of (±) 1 K. The heat pump stops
when the evaporator temperature gets too low. The temperature limit for defrost
is -18 °C.
Chosen operating settings are indicated by lamps in the front panel (25, 26).
The upper (25) is for the heat pump and the lower (26) is for supplementary
heating.
2.9 Heating coil
CTC EcoWater (model 301) is equipped with a heating coil with 1 m2heat
surface. When using the coil, thermostats must always be mounted on the
primary flow and the storage to ensure the correct temperature. To ensure
the water capacity the storage temperature must always have the 1st priority.
Additional heat may not exceed 65 °C, higher temperatures can damage the
heat pump circuit.
2.10 Fan control
The fan has 2 speeds which can be adjusted in the menu “FanOper”. Normally,
the highest speed should be used (Option 2 in the menu “FanOper” is the high
speed). The noise level can be reduced by decreasing the fan speed. Lower
speed setting can be selected with minor influence of the heat pump efficiency.
With air duct connections the highest speed always must be used. The fan
can, in the ”FanCon” always be connected so that a constant ventilation can
be made. The fan will in the setup 0 be disconnected with heat pump. In
setup 1 it runs on low speed and in setup 2 it runs high-speed with heat pump
disconnected.
Off: Inactive.
Orange: Activated but in standby
mode.
Green: Activated.

"FanPause" is a function for preventing the overflow of condensation water
if the heat pump is placed in a room with high air humidity. When activated,
the fan will stop either for 15 or 30 seconds per hour unless the heat pump
has reached its set point and the compressor and fan stops automatically.
If "FanCon" is activated, then the "FanPause" function still works. When the
set point has decreased enough, the compressor and fan start again and
the "FanPause" function is automatically activated from the moment the
compressor and fan start. If "FanPause" is set to "Off", then the function is
deactivated.
2.11 Electrical installation
The heat pump is to be used on 230V, 1N~ (single phase). The product is
equipped with a 2 m power supply cord, 3 x 1.5 mm2and a European socket.
The power supply shall be connected to a socket with a security breaker. For

3.2 Anode
The storage tank is corrosion protected internally with enamel. To prevent corrosion in the small defect that can
appear with enameled corrosion protection an automatic sacrificial anode is placed in the storage. The anode menu
will show "Auto", and alarm no. 9 will light up if the anode is worn and has to be replaced.
Defrosting
If the temperature at the evaporator is -2 °C or less, defrosting is activated. The time interval between the defrosting
periods is 2 hours. This means that a defrost sequence is started every 2 hours as long as the evaporator
temperature is below -2 °C. During the defrost sequence the bypass valve opens, the compressor will run and the
fan is switched off. When the evaporator temperature reaches +5 °C, the defrost cycle is stopped and the bypass
valve closes, and the fan starts. If the temperature for the evaporator does not reach +5 °C within 20 minutes, the
defrosting will stop and the normal operation is continued anyway. If the evaporator temperature reaches -18 °C or
less the heat pump will stop. The supplementary heating source (if activated) will be used.
3.3 Legionella
The legionella function can be activated in the control system. If the function is activated the sequence will start
immediately. After 7 days (168 hours) a new legionella sequence will start. During the legionella sequence the water
temperature is raised to 65 °C using the heat pump and the additional heating source. This temperature is held for
1hour before switching back to normal mode. If the temperature is not reached in 12 hours the function will timeout.
An alarm will be presented in the display. The alarm will be reset as soon as a successful sequence is made (or if the
alarm is confirmed by user). Reasons for a timeout; too low air temperature and/or water use is higher than the power
input and/or supplementary heating is blocked.
!For best performance, the Legionella function shall be activated when the
domestic hot water demand is low. for example at 22.00.

4. Alarm handling
There are three different alarm levels; information
alarms, heat pump circuit alarm and system alarm.
Three different alarms can be stored at the same time.
Each alarm must be reset by pressing the control button
at the control panel.
The information alarms do not stop the heat pump, but
informs the user that there is a disturbance that has to
be solved as soon as possible (Alarm no: 8, 9 and 10).
The heat pump circuit alarms stop the hot water
production with the compressor and switches to
100 % supplementary heating sources (immersion
heater or external boiler). (Alarm No: 3, 4, 5 and 6).
System alarms blocks the whole product. (Alarm no: 1
and 2).
The alarms are presented in the alarm menu, where
also the alarms are confirmed. Each alarm must be
confirmed before normal operation is possible. If no
action is taken before an alarm is confirmed the alarm
will still be on. In the case several simultaneous alarms,
they are placed in a row. The alarms will be presented in
order of importance.
Pressure switch alarms
Pressure switch alarm (5, 6) will be handled in the
following way;
At the first break, alarm no. 5 will show in the display
and lamp (25) flashes. The heat pump will stop and
automatically restart. If the error is eliminated, the lamp
(25) will switch to flash orange, and after the alarm is
confirmed constant orange or green.
If a second alarm occurs less than 6 hours after the
first alarm, alarm no. 6 will show in the display and the
heat pump will stop. The heat pump can now only be
restarted by confirming the alarm. With alarm no. 6 the
lamp (25) will flash red. When the pressure switch is
controlled and repaired the alarm can be confirmed and
the product restarted.

5. Maintenance
5.1 Replacing the anode
The anode has to be replaced when the alarm no. 9 is presented in the
display. The anode (7) is situated behind the front cover. Before the anode is
replaced the storage has to be emptied. This is made by turning off the cold
water supply and then open the drain valve (on the cold water inlet). At the
same time the hotwater tap has to be turned on to avoid negative pressure
inside the tank.
5.2 Maintenance of the evaporator
Once or twice a year the evaporator should be examined and cleaned
if necessary. To reach the evaporator the air inlet/outlet ducts has to
be removed. If not cleaned the heat pump capacity will decrease. The
evaporator is preferably cleaned with water and a brush. Avoid any water
on electrical parts! The evaporator fins must not be damaged. The intervals
needed for cleaning is depending on the air quality. If the air used for the
heat pump contains a lot of particles, a more frequent cleaning may be
necessary.
Maintenance of the drain
The condensation water outlet must be connected to a drain in accordance
with the present regulations. The defrost/condensed water outlet of the
heat pump must always be kept free from dirt. How frequent this has to
be done depends on the local conditions concerning dirt, humidity and air
temperature. A blocked outlet causes the defrost/condensed water tray to
flood and the fault circuit breaker may cut if electrical parts are exposed to
water.
The warranty does not cover damages caused by lack of maintenance.

6. Troubleshooting
Information / Failure Action / Cause
There is water on the floor around
the product
Check that the heat pump is standing horizontally
Check the connection of the drain tube
Check if there is any dirt in the drain tube
The compressor does not start even
though the water temperature is
below setpoint
If the compressor recently has been running there is a start delay for 5
minutes
The water is not hot enough Increase the set point to a higher value
Adjust the mixing valve for hot water
The compressor runs constantly but
still there is no hot water
If a lot of hot water has been consumed it can take a long time for the
heat pump to reach the set point
Is the evaporator is blocked by ice or dust? Clean and restart.
If there is a small radiator system connected this might take too much
energy. If so install a thermostat to let hot water production be first
priority.
If there is hot water circulation installed this must be controlled by timer to
make it possible for the heat pump to produce enough hot water.
There might be a leakage in the refrigerant circuit. Contact service.
High pressure alarm (Alarm 5) The air through the evaporator is too low. Clean and reset the alarm.
The temperature in the tank is too high. Change the tank sensor and reset
the alarm
The temperature in to the heat pump is higher than +35 °C
The temperature on the evaporator is
below -19 °C. (Alarm 4)
Wait until the temperature rises to more than -10 °C.
If the alarm repeats contact service.

Félicitations
Nous vous félicitons pour l’acquisition de votre nouvelle
pompe à chaleur pour eau chaude sanitaire. Nous sommes
certains que vous serez pleinement satisfait de la qualité
de ce produit. Nous vous recommandons de lire
attentivement ces instructions avant de la mettre en service.
Cesinstructions renferment les informations nécessaires
pour installer et utiliser votre nouvelle pompe à chaleur.
La pompe à chaleur couvre normalement les besoins
d’une famille en eau chaude sanitaire tout au long de
l’année. Selon les modèles CTC EcoWater est équipé
d’un serpentin incorporé comme chauffage d’appoint à
partir
d’une chaudière externe, de panneaux solaires, etc.
Information destinée à l’installateur
Il est nécessaire de lire soigneusement ce manuel
avant de procéder à l’installation; il comprend toutes
les informations nécessaires pour l’installation.
Tenez compte des normes et réglementations locales
relatives à l’eau avant de mettre le produit en service.
Il faut particulièrement prendre en compte les qualités
de l’eau dans le cas de teneurs importantes en,
par exemple, calcaire et impuretés.
Avant la première mise en marche, vérifiez que le
système est rempli d’eau et qu'il a été purgé. Assurez-
vous que tous les raccordements sont serrés.
A la première mise en marche, ou lorsque le ballon a été
vidé, il faut de 8 à 10 heures de marche à une température
d'air de 15 °C pour atteindre une température d’eau de
45-55 °C.
Principes de base du chauffage
La pompe à chaleur fonctionne sur le principe air/eau;
c’est-à-dire que l’air est aspiré à travers un évaporateur
et refroidi. L’énergie thermique de l’air est transformée
dans le compresseur à une température supérieure,
puis transférée à l’eau dans la chaudière au moyen
d’un échangeur de chaleur.
