Identification of the delivered model
The entire fan coil series is manufactured in different models,
ranging from devices for installation in false ceilings and floors
(horizontal model) to devices with a device casing for installa-
tion in open space (horizontal and vertical models).
Register group (a) : It consists either of a single register for cooling
or heating (connection to two pipelines) or of 2 registers of 3 + 1
pipe rows (connection to 4 pipelines). The registers contain copper
pipes, aluminium ribs, a draining or ventilation system and a galva-
nised steel frame. The water connections are located on the right-
hand or left-hand register side. Optionally, an electric heating reg-
ister can be used to support the heating mode.
Housing (b) : Galvanised sheet steel 1 mm in thickness and heat or
sound insulation 6 mm in thickness with fire classification M1.
Motorised fan (c):1 The motorised fan consists of 1, 2 or 3 dou-
ble-sided intake-operated radial blowers with forward curved
blades and direct drive. The fan motors are designed as 230V AC
or highly efficient EC motors and are equipped with mainte-
nance-free friction bearings for a long service life. For the AC fan
motor, 6 steps are made available by a step transformer. The EC
fan can be activated by 0-10 V and is almost infinitely variable.
The housing and the fan wheel are made of plastic and are opti-
mised for the lowest possible sound pressure.
Filters (d): Their efficiency class is G2 and G3 and they consist
of synthetic fabric on a plastic frame.

fully checked, in order to guarantee that no transport damage
has taken place. Moreover, the dimensions, composition and
number of the identification plate must be checked as to wheth-
er they are as ordered. To prevent possible damage during
transport, the devices will be delivered ex works on pallets (that
correspond to the particular weight and dimensions). When
several units are stacked on top of each other, boards are used.
The entire delivery is then wrapped with transparent plastic film
and secured with tape. It is recommended leaving this protec-
tion in place until the device is commissioned.

Installation site
The Aquaris Silent units are available as horizontal model (for in-
stallation of the device unit in false ceilings and floors or free-
standing with device casing) and as vertical model (for installa-
tion on walls, in niches, with or without device casing). The de-
vices must not be installed in places with extreme moisture (e.g.
laundries or swimming pools), with high dust formation, out-
doors or in places subject to explosion hazards.
For correct mounting, the following instructions must be fol-
lowed:
Horizontal mounting
When mounting the fan coil in a false ceiling, the device is fixed
at a load-bearing ceiling using threaded bars or other fastening
material approved by the building supervisory authorities.
To reduce the noise generated by the fan coil unit, it is recom-
mended fastening the device and the connections of the pipe-
lines by means of sound-insulating elements or vibration
dampers.
When the device is installed in false ceilings, the device unit is at-
tached using the anchoring elements of the fan coil. When in-
stalled in open space, the device is suspended using additional
brackets enclosed with the device housing. This is followed by in-
serting the device enclosure, which is supported by the housing.
In any form of horizontal installation, the device is mounted at
an inclination of 10 - 15 mm to ensure draining of the water of
condensation.
Vertical mounting
The fan coil is mounted
vertically on the lateral
sheet metal frame using
fastening material ap-
proved by the building su-
pervisory authorities. If
the fan coil has a device
enclosure, the latter is
fastened to the sheet met-
al frame of the fan coil by
means of the fishplates.
To ensure correct air
flow, devices with device
enclosure or without return air grilles must be installed at a min-
imum distance of 100 mm from the wall (horizontal installation)
or from the floor (vertical installation).
To avoid damage to the device enclosure, it is recommended
first installing only the device unit and to insert the device enclo-
sure not until these activities have been completed.
- Make sure that places that are intended as openings for air
admission and air discharge are free of pipes, electric cables,
crossbeams, stands, etc.
- Install the unit at a site that has good air quality.
- Make sure that wall and ceiling correspond to the weight of
the device and also allow correct mounting of the fastening
elements.
- Make sure that no obstacles are present on the outside of the
wall that could impair optimum air circulation (plants, furni-
ture, curtains, etc.). No objects must be placed on the vertical
models of the device. Nor must they be used as seat.
- Install the device such that the air flow is not directed directly
at persons staying there.
- The installation site must have sufficient space and the nec-
essary resources for carrying out mounting and maintenance
activities of all device components.
min. 100 mm
min. 100 mm
For maintenance and inspection purposes, a suffi-
cient number of openings with an appropriate size
must be provided to ensure access to all compo-
nents (see also VDI 6022).

Mounting and connections
The work or support surface used for assembling the device
must be smooth and level, to ensure that damaging tensions are
avoided when the sub-assemblies are attached.
Connecting the sub-assemblies
The fan coil base unit (register, filter and motorised fan) is de-
livered completely mounted ex works. The only connecting work
to be done by the installer is attaching the fan coil to the availa-
ble air ducts or fastening the plenum boxes to the main unit.
Connecting the air ducts
The fan coil is provided with a flange (-FL) (if indicated in the or-
der) on the supply air side for attaching the air duct. For the re-
turn air, the fan coil unit has openings in the return air
connection piece, which can be screwed to the air duct. For ple-
num boxes with connection pipe, the air ducts are attached by
means of clamps, fishplates or the like.
If on-site components are used, a seal with a thickness of 2 mm
between the suction flange and the plenum box is required for
the filter change.
Plenum boxes
The plenum boxes for supply and secondary air are mounted to the
main unit using optionally available flexible connection pieces.
Flexible connections
Flexible connections that prevent
a transmission of vibrations to
the system can be additionally
delivered as an option.
They are assembled by screwing
the flexible connections to the
device unit.
Before making electric or hydraulic connections,
the power supply must be disconnected.
Non-observance of the device inclination may re-
sult in serious damage to the device and cause wa-
ter to enter the air ducts.
For installation of the device, use adequate tools,
devices and materials and observe the safety reg-
ulations and other current regulations.
SCHAKO cannot be held liable for damage result-
ing from faulty installation or the use of unsuitable
fastening devices.
Before connecting the plenum boxes, make sure that
the insulation at the plenum box frame is in good
condition.

05.04.2013Version:
Hydraulic connections
Upon customer request, the water connection to the registers
can be established either on the left-hand or right-hand side of
the unit. The pipe for the supply of liquids is attached below the
collector, and the return flow above the same. The registers are
equipped ex works with a manual bleed valve. Any further devic-
es for ventilation must be provided on-site.
If the unit is to be installed at a location having temperatures be-
low zero degrees, glycol must be admixed to the coolant in a
suitable ratio, to ensure that the freezing point of this liquid al-
ways stays below the minimum temperature of the operating
site. Please note that the use of an antifreeze results in a loss in
efficiency of the device.
For the mounting of flexible hoses, the current installation
guidelines of the manufacturer are valid.
Electric connections
Prior to the electrical installation, you have to make sure that the
rated mains voltage is 230 V, 50/60 Hz and is single-phase. The
delivered motors have insulation of type B and protection class
IP21 (
SP series ) or IP20 ( EC series ). The electric connections
must be made by qualified electricians only, observing current
regulations and the low-voltage directive.
SCHAKO recommends using exclusively copper cables, since
the device connections have not been designed for accommo-
dating other types of cables. If they are used nevertheless, gal-
vanic corrosion or generation of heat could take place at the
connection point.

Venting device
When making the hydraulic connections, suitable
tools must be used, to avoid a rotation or other
movements of the collector and excessive tighten-
ing of the connections.
Avoid putting the register connections under
stress as a result of the weight of the connection
pipes.
If flexible hoses are to be used, observe the bend
radius specified by the manufacturer or the current
specifications.
For all accessories, the specifications of the re-
spective manufacturer must be observed.
Ensure that no air remains in the hydraulic circuit
by providing venting devices.
Connect the fan coil unit via an earthing cable.
Interrupt the power supply, before carrying out any
electrical connection work.

Mounting accessories
Temperature controls
The temperature controls are mounted in accordance with the
selected model. This is why the instructions enclosed with each
model must be followed. However, in order to achieve optimum
measurement by the sensors, the following basic information
should be observed:
Actuators
The installation of the actuators depends on the selected model.
Please follow the instructions enclosed with each model.
Valves
The valves are already mounted ex works, no further installation
being required. Upon customer request, the device can also be
delivered without valves, in which case the instructions of the
valve manufacturer have to be followed.
Condensate pump
Installing a condensate pump allows the condensate produced
by the Aquaris Silent to be removed, even if the water discharge
is higher than the condensate discharge.
If the main water drain is above the level of the Aquaris Silent
drain, such a pump has to be mounted. The condensate pump
prevents a water overflow of the Aquaris Silent.
The condensate pump delivered ex works is equipped as stand-
ard with a potential-free NC contact acting as a safety switch. If
draining is impossible (clogging, excessive formation of con-
densate, pump failure, etc.), it is possible to trigger a fault mes-
sage via the safety switch or interrupting the device or the
supply of the control valve. This function must be set ex works.
The diagram shows the capacity of the condensate pump as a
function of the vertical distance (V) and the horizontal distance
H (relative to the latent cooling capacity).
Electric connections of the condensate pump
- Do not mount the temperature control close to or above a
heat source (direct sunlight, lamps, television sets, radia-
tors, etc.), in places with draught air or directly opposite
to an air diffuser grille.
- Temperature controls must be mounted at least 1.5 me-
tres above the floor.
- Mounting temperature controls on walls toward the out-
doors should be avoided.
Faulty mounting of the sub-assemblies and of the
Accessories of the unit can result in a substantial
power loss of the unit.
Before drilling, make sure that no power, water or
gas lines are present where the temperature con-
trols are to be mounted.

Checks
Prior to commissioning, the following items must be checked or
guaranteed:
During commissioning itself, the following items must be guar-
anteed:
Maintenance
For reasons of safety, the power supply and hydraulic circuit
must be disconnected prior to any maintenance activity.
If the unit was operated in heating mode, you have to wait until
the register has cooled down.
Disassembling the units
Access to the device for carrying out maintenance activities is
made available by unscrewing and taking off the appropriate
metal sheets.
In doing so, the following instructions must be followed:
Dismounting the condensate pan
Dismounting the additional condensate pan
Motorised fan
The motorised fan does not require any special maintenance, as
it is equipped with self-lubricating bearings. However, the
blades and the rotor of the motor must be checked at regular in-
tervals as to whether they are free of dirt.
If required, it is cleaned with compressed air or by carefully
brushing the motor surface or the housing.
- The air flow through the filters is not impaired by foreign ma-
terial (paper, packaging residues, etc.).
- The current consumption of the device is not higher than the
power of the electric circuit it is connected to.
- The electrical properties of the device correspond to those of
the electrical connection circuit.
- Hydraulic connections were tightened properly and exhibit
no leaks.
- Electrical connections were made in compliance with the cur-
rent regulations.
- Connecting and fastening elements have been sufficiently
tightened.
- The drain pipe of the condensate pan is not clogged.
- There is a sufficient gradient for the condensate pan to be
emptied correctly. (Check whether it is completely emptied
by partly filling it.)
- The insulation kit was attached correctly to the pipes of the
condensate pan.
- Adequate access for carrying out the maintenance activities
has been provided.
- The motorised fan does not exhibit any vibrations or exces-
sive noise.
- The connecting and fastening elements have been sufficiently
tightened.
- The condensate pan is emptied correctly.
- In heating mode, the temperature of the discharged supply air
is not above 40°C.
After carrying out the activities described above,
the correct installation of the unit must be checked.
When performing maintenance activities, it is rec-
ommended wearing personal protective equipment,
in order to avoid cuts and other injuries produced by
sharp and pointed parts.
- Take out the filter by
folding it downward
- Unscrew the lateral
screws (2x) and the
screws on the connect-
ing pipes
- Removing the metal
sheet
- Disconnect the electrical
connections (boxes) and
unscrew the screws (4x)
of the fan unit
When the metal sheets are removed, the unit must
not be in operation.

Registers
To guarantee the technical characteristics of the device, the reg-
isters and heat exchangers must be kept in good clean condi-
tion. To ensure this, the following maintenance activities must
be carried out:
Filter
Filter maintenance is limited to cleaning or replacing it as soon
as a certain pressure drop value is reached. The service life of
the filter depends on its efficiency and on the degree of soiling
of the air arriving there. This is why it is recommended to check
it once every three months. In the absence of a recommendation
on the part of the manufacturer, the maximum pressure drop
value must conform to current regulations (see UNE EN 779).
The reconditioning and replace-
ment of the filters are described in
chapter "Removing the filters". In
doing so, make sure that the dust
is not distributed in the surround-
ings.
The filter is cleaned with com-
pressed air or by washing it with
warm water and a mild detergent.
Before mounting it again, the filter must be dried completely.
Removing the filters
- Check the condition of the register at least each time the filter
is changed.
- Should the register be soiled, clean it by spraying it with wa-
ter or with compressed air or by suction.
- If there are larger differences in distance between the ribs,
they must be "combed".
-
Once a year, the condensate pan must be checked for formation
of algae, to prevent possible clogging of the drain pipe. Check
whether the pan is completely emptied by partly filling it.
- Ventilate the hydraulic circuits of the register. In doing so,
watch out for possible leaks of the hydraulic system.
If you want to change the operating conditions of
the fan (speed, pressure, temperature, etc.), first
contact your local SCHAKO sales partner, in order
to find out whether the unit can be safely operated
under the changed conditions.
When decommissioning the unit or shutting it
down for a longer period in winter, the water must
be drained from the unit, in order to avoid damage
to the register due to the formation of ice. If you
want to use antifreezes, you must first determine
the freezing point.
The maintenance activities must be carried out ac-
cording to current standards, for example: VDI
To precisely monitoring the pressure loss of the fil-
ter, it is recommended using differential manome-
ters or pressure monitors.
If there are any devices in the surroundings that
exhibit high dust formation, a monthly check and
cleaning must be carried out (smoking rooms,
kitchens, etc.).
