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.

2 Safety

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

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 Unit structure

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.

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.

Consumption: 7mA Max. 0.31 VA

Internal sensor: 5 .. 40 °C

Quick Time constant: 15 s

Protection class: IP30 (to EN60529)

Weight: 108 g

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.
