3.Specification
3.4 The working principle of units
This Vertical Water Fan Coil is a terminal which uses water to provide heated air in winter
and fresh cooled, dehumidified air in summer (fig.4).
Compared with the traditional fan coil, the newly designed Water Fan Coil is thinner,
quieter and nicer and can be installed in various ways such as floor installation, wall
installation, ceiling installation and concealed installation, thus the installation cost is
reduced.
3.5 Unit characteristics
(1) Super quiet
The use of cross-flow fan combined with newly wind-guiding technology makes lower noise
and you can enjoy a healthier and more comfortable sleep.
(2) Ultra-thin
Compact structure and thin casing (only 130mm thickness, the traditional fan coil is always
with the thickness of 250mm) leave more space for your room.
(3) Fashionable shape
With module-noble & fashion arc frame and color, it will be wherever it is
in your room.
elegant inviting
(4)Humanistic controlling
The ultra-thin fan coil applies the newly built controller which is with the super quiet airflow
design and the running modes of heating and cooling. Remote controller can be also used
to manage the unit.

4.1 Installation precautions
4.1.1 To ensures that the installation is performed correctly and that the appliance will
perform perfectly carefully follow the instructions indicated in this manual. Failure to respect
the rules indicated not only can cause malfunctions of the appliance but also invalidate the
warranty and hence the manufacturer shall not respond for any damage to persons, animals
or property.
4.1.2 It is important that the electrical installation is made according to the laws in force,
respects the data indicated in the technical sheet and is correctly earthed.
4.1.3 The appliance must be installed in a position that allows the routine maintenance, such
as filter cleaning.
4.2 Positioning the unit
4.2.1 Avoid installing the unit in proximity to:
-positions subject to exposure to direct sunlight;
-in proximity to sources of heat;
-in damp areas or places with probable contact with water;
-in places with oil fumes
-places subject to high frequencies.
4.2.2 Make sure that:
-the wall on which the unit is to be installed is strong enough to support the weight;
-the part of the wall interested does not have pipes or electric wires passing through;
-the interested wall is perfectly flat;
-there is an area free of obstacles which could interfere with the inlet and outlet air flow;
-the installation wall is preferably an outside perimeter wall to allow the discharge of
condensation outside;
4.3 Minimum installation distances

Before you installed the unit on the floor,the feeting should be mounted: First, lay down the
unit, next take out screws and two feet from accessories bag,then make the feet are match up
with screw holes A/B/C/D, finally apply four screws to each side to fix the feet.(See Fig.9 and

Do not over-tighten the screws so that the brackets can be adjusted with a spirit level (Fig.12).
Then fully tighten the four screws to block the two brackets.
Mount the unit, checking that it fits correctly onto the brackets and checking that it is stable
(Fig. 13).
Attention:
The hydraulic lines should be with the least resistance.
Piping system should be clean, no rust slag and jam in the pipeline. There will be no
leakage in the hydraulic lines and insult the lines after finish the connection.
The hydraulic lines should be connect to the water tank and the height of the water
should be 0.5 m higher.
Y type filter should be installed in the water inlet of the unit.
Air release valve should be arranged on top of the hydraulic lines to avoid air
retention.
Waterway system should be conducted the pressure test separately and not together
with the Vertical Water Fan Coil.

4.4.4 Evacuating air while filling the system
If there is no electric power and the thermo-valve has already been powered use the special
cap to press the valve stopper to open it.
Start the filling by slowly opening the system water filling tap. Use a screwdriver to
unscrew the side battery breather (fig. 20 ref. A). When water starts coming out of the breather
valves of the appliance, close them and continue filling until reaching the nominal value for the
system. Check the hydraulic seal of the gaskets.
It is advisable to repeat these operations after the appliance has been running for a few hours
and periodically check the pressure of the system.
Attention :
-When discharging directly into the main
drains, it is advisable to make a siphon to
prevent bad smells returning up the pipe
towards the room. The curve of the
siphon must be lower than the
condensation collection bowl.
-If the condensation needs to be
discharged into a container, it must be
open to the atmosphere and the tube
must not be immerged in water to avoid
problems of adhesiveness and
counter-pressure that would interfere
with the normal outflow.
4.4.3 Condensation discharge
When mounting the condensation discharge device in the vertical version, connect to the
condensation collection tray discharge union (fig.19 ref. C) a pipe for the outflow of the liquid
(fig. 19 ref. B) blocking it adequately. The condensation discharge network must be suitably
sized (minimum inside pipe diameter 16 mm).
