compromises on comfort or energy use.
Please read this user guide with care and keep it to obtain
the most benefit of this advanced system. Huge benefit not
only for the climate, but also in your building
For many buildings, heating and cooling the indoor climate
is a huge cost factor. For that reason alone, there is much to
be gained. The TripleAqua climate system enables you to
independently heat and cool different rooms as required, but
using up to 50% less energy. This makes it one of the most
efficient systems in the world. Aim: to bring your building to
energy label + ++
A level!
High quality system, low water temperature
A heating system is, in fact, a huge energy consumer.
TripleAqua utilizes a heat pump combined with high
efficiency indoor units. Thanks to the system’s
unprecedented heat transfer, a much lower water
temperature suffices, with huge savings and minimal losses
as a result.
Smart storage and energy exchange
Cooling with a heat pump during the day creates waste
heat, while heating creates waste cold. Other systems reject
surplus energy immediately. What a waste! TripleAqua
exchanges this energy between rooms and passively stores
the surplus heat and cold and uses them for free heating
and cooling. This results in spectacular energy savings,
particularly during the spring and autumn.

3 Transport, storage, handling
and positioning
from the pallet, to be taken directly to its’ assigned space for
immediate installation.
It is the sole responsibility of the customer to provide the
protection necessary to prevent vandalism and weather
deterioration of the equipment. Under no condition should
the units be left unprotected from the elements. If the
equipment is not needed immediately at the job site, it
should be left in its shipping carton and stored in a clean, dry
area of the building or in a warehouse.
DO NOT place units in corrosive environments or in locations
subject to temperature or humidity extremes (e.g., attics,
garages, rooftops, etc.). Corrosive conditions and high
temperature or humidity can significantly reduce system
performance, reliability and overall life.
The equipment is NOT suitable for outdoor installations.
Before installing any of the system components, be sure
to examine each pipe, fitting and valve, and remove any
dirt or foreign material found in or on these components.
Manufacturer’s warranties are void if foreign material is
allowed to be deposited in the drain pan, valves, pipework,
or on the motor or fan wheels.
3.4 Lifting and Handling
Coils and some parts are sharp. Avoid touching these parts
while handling the unit.
Large units may be heavy. Move them with two persons.
Although TripleAqua is designed for durability and fabricated
with heavy gauge materials and have a robust appearance,
care must be taken to assure that no undue force is applied
to the casework, coil, piping, drain connection or other
components such as control boards during handling.
Wherever possible, all units should be handled by the
cabinet, or as close as possible to the mounting points.
In the case of a fully exposed cabinet unit, the unit must
obviously be handled by the exterior casing. Gloves should
be worn when handling finished, painted units and should
never be set down on unclean, hard surfaces. There is a risk
of scratching the painted or finished surface.
3.5 Anchoring and positioning
Anchoring
In all cases, the steel structure of the unit needs anchoring.
Suitable holes (4 to 6 pcs) are foreseen at both sides and
suitable for this purpose.
Sufficient clearance must be provided for service and
removal of the parts. See 5.2 drawings.
3.1 Transportation
TripleAqua units are supplied fully assembled and tested
(except for accessories supplied loose). They are ready to be
installed, commissioned and operated in the field.
3.2 Storage
If, on site, the unit must be stored out of operation, before
commissioning, the installer is to follow the following
precautions to prevent frost, damage, corrosion and/ or
deterioration:
• Keep the unit packed in the box as long as possible
• Check if all openings, such as for electrics and water
connections, are plugged and sealed.
• Never store the unit where temperature may rise
above 50 °C
• Minimum storage temperature is -25 °C, only if the unit
is properly drained, no water inside
• It is recommended to leave the finned coils covered
with the transportation cover to protect them against
any risk of damage which is likely to occur on
construction sites.
• Never use steam to clean the unit.
• Check the unit on a regular basis for visual damage
• Remove the tools required to access all the panels
and secure them well on site.
3.3 Receiving and Inspecting
Directly upon receipt, the INSTALLER shall immediately
inspect the unit for any damage since it has been delivered
ex works and transported at the customer’s risk. Also, check
if all the goods and parts have arrived as specified on the
delivery note. Check all goods carefully. Damage should
be reported immediately (within 4 hours) in writing to the
carrier and the distributor. Even if the damage is only on the
surface or box, please notify the local TripleAqua dealer as
well.
The manufacturer disclaims all responsibility for the
shipment even if it has organized the transport.
All units are carefully inspected at the factory throughout the
entire fabrication and assembly processes. All components
such as motors, coils, controls, valve packages and more,
are carefully tested for proper operation, visually inspected
and verified for full compliance with factory standards.
Operational testing for all components has been performed.
Units are usually shipped on pallets of up to 5 units. Single
units are packed in boxes. Each unit is factory tagged
according to the label. This allows the unit, upon removal
8
Filters can be removed from the back or bottom on
horizontal mounted units and from the front on vertically
mounted units. Do not handle unit by coil- or piping
connections as damage may occur. Anchoring the
equipment in place is accomplished by using the mounting
points provided, and positioning the unit on a LEVEL
horizontal plane. The positioning is correct if the drain pan
is pitched horizontally to provide proper drainage when the
unit is installed level.
Units can be installed horizontally and vertically.
Units are designed to be bolted to the wall structure through
the slotted wall mounting holes in the chassis, used for
anchoring to pre-installed studs.
Fixing is provided with the identical mounting slots in the
top panels with hanging rod and field supplied rubber-in-
shear insulators. They can be used for proper suspension and
vibration isolation only in very critical applications.
The type of mounting device is a matter of choice, however
the mounting point should always be at the 4 to 6 points of
the cabinet.
Check that your lifting equipment can safely support the unit
assembly and component weights. See technical data for
unit weights.
All supports must be designed to meet applicable local
codes and ordinances. All fastening devices must be
designed to mechanically lock the assembly in place without
the capability of loosening or breaking away due to system
operation and vibration.
After mounting the unit, it is ready for the connections such
as water, drain and electrical.
3.6 About the Installation Site
When installing the unit, make sure that the
building structure and/or the supporting surface
can withstand the weight of the device. The
weights of the units are detailed in the technical data.
These units have been designed to be installed on the
floor, a wall or a ceiling. Normally rubber vibration damping
supports and internal flexible pipe work are not required.
When the unit is to be installed on the ground, provide for
a concrete supporting plate which shall assure a uniform
distribution of the weights. A special subbase / feet is
generally required.
When selecting the installation site, follow these guidelines:
• The unit must not be installed in the proximity of
open fire or greasy environments: the discharge of
boiler flue gases.
• The unit is installed level on an even surface
• The unit is not allowed to be installed near sources
of contaminated air, like chimneys or exhaust pipes
and the outlets of large-kitchen extractors. Grease might
build up on the fins of air exchangers and filter.
• Although the unit is extremely silent, the valves actuators
and fan(s) may generate a few dB(A) more sound than the
background noise level. In very sensitive situations,
please insulate the unit acoustically in the most
beneficial way.
• Contact an acoustical engineer for obtaining the
most beneficial acoustical results.
• The total experienced sound pressure level in a room is
greatly affected by the room merits.
• Never install in areas exposed to flooding or beneath
drip stones, etc.
• The installation site is suitable for the space required
for air circulation and for the performance of
maintenance operations

4.2 Drain pan
The condensate drip tray and the external connection are made of full stainless steel AISI 304
with outer insulation against condensation. In case of cleaning service, the drip tray is easy to
remove.
Due to a POSITIVE discharge pressure in the drain tray section, condensate water is additionally
driven away into the drain pipe. This positive pressure reassures that condensate water cannot
be staggered or sucked inside the drain tray. Also, the positive Pressure in the drain tray makes
it almost impossible that odours of the drain system can enter the TripleAqua unit. This design
is more costly, but avoiding contamination, cleaning, complicated service and hygienic issues
in the life time of the system matter too. Equipped as standard with close cellular expanded
synthetic insulation. The connection from the condensate tray to the external pipework is by a
strong ½”BSP thread. This solid connection avoids any leaks.
11
4.3 Ultra efficient EU5 / M5 air filter
Clean air means healthy air! The most important merit of indoor air quality is the
cleanliness. Air contamination consist of small particles that may reduce the well-
being and health of humans. Unlike other dx-units and fan coils, this is why the
TripleAqua is equipped with special (M5 to EN779) ultra-efficient micro-filtration
cassettes filters, able to filter out these particles, polls and fine dust even as small as
5μ. (0.005mm) throughout the filter’s lifetime ensuring you clean air! Close pleats
ensure lowest energy consumption, an excessive large filter area and high efficien-
cy and life span.
IMPORTANT
• Only the original filters will fit and
may be used.
• Filters cannot be cleaned.
• Filter material is enclosed by a stong,
water-resistant ABS casing.
• It is made of recyclable synthetic material.
• Filters must be replaced by original
TripleAqua spare parts.
Other types are not allowed.
• Used filters shall be disposed according
to local regulations, not in unsorted
municipal waste.
Filter replacement interval : The average usable time is 6 to 12 months. However, if
the white colour of the filter turns dark, please replace.
The filter use is always counted and checked by the controller, both in terms of
running hours as well as air volume filtered. When the FI:LT sign is shown shortly,
it is a pre-warning as it is about time to schedule a filter change soon. Meanwhile,
the unit may operate normally. Due to the extended 60mm thickness, long life and
convenient service intervals are possible. The filters can be replaced without any
tools. Clips on both side of the unit casing provide easy replacement, even in tight
surroundings. Filters come in four standard TripleAqua sizes, suitable to service all
models, limiting the number of service components. If the filter warning is ignored,
FI:LT is to be shown permanent and the unit capacity is reduced significantly, also
internal contamination will occur.

4.4 EC-fan
The Motor-Ventilator is a double suction, dynamically
balanced radial forward curved with direct driven controls.
Only available with the most efficient EC Motors, mainte-
nance free bearings for long life. Unlike other fans using
plastics, our motor, the casing and the fan wheel is fully
made of strong metal parts. EC-Ventilators can operate step-
less with intelligent electronics at the lowest possible speed.
It makes them up to 75% more economic than AC fans. Ultra
low speeds are the best choice in silent applications such
as hotels. Unit may operate even lower than the human ear
threshold value!
A remarkable feature is the intelligent Motor management.
Within the operational range and external pressure, the air
volume of the fan is kept constant, regardless the change
of external pressure or operating condition. The fan just
maintains the air volume as demanded by the 0-10 V signal!
This is an important move towards full thermal control of the
unit output.
An internal thermal overload protection is as standard. These
fans set the new standard in modern fan coil applications!
As a standard, these radial ultra-low noise and low speed EC
fan(s) with extra-large wheel diameter (146mm) and forward
bended shaped blades in full metal. The fans are double
balanced and coupled directly to a very energy efficient
DC single phase electric rotor motor with internal thermal
protection incorporated in version IP 44.
Fans are housed in a metal scroll casing, aerodynamically
shaped to increase aerodynamic efficiency and minimize
noise levels. The fans are produced in best European
factories. The efficiency is by far exceeding criteria as set in
the ErP2015 directive: Even at full power, the fan(s) used in
the TripleAqua consume less than 0,095kW!
Not sensitive to external pressure
Unlike other radial fans, the TripleAqua fans have full internal
compensation for change of external pressure, reassuring
the air volume delivered at the desired level as given by
the 0-10V controls. This feature enables the system to keep
the heat transfer performance independent of external
variations, such as filter contamination, external pressure
and unforeseen conditions. Having total control over
the air volume delivered is an essential to guarantee the
performance of the indoor unit in terms of capacity and
return temperature.
4.5 Room controller
Mostly, in a room, Room Controller(s) (RC) shall be mounted.
The wired RC model is known as 3RC866.
In large (open plan) rooms, more RC of this type may be
present. It facilitates the controls and the room temperature
is measured at more locations. Maximum 6 RC can be
connected to the local bus. Each RC has a local temperature
sensor. TripleAqua calculates the average temperature of all
sensors, which will become the average room temperature.

5.2 Space requirements
For proper operation and maintenance access, a free area
around the unit has to be observed. Do not place any objects
in this area. The area is intended for free air inlet and access
to all internal parts of the unit. In the unlikely event of a se-
rious defect, large components such as air heat exchangers,
compressors or similar, need space to be able to replace.
