The working principle of CXI units
This Water Fan Coil is a terminal which uses water to provide heated air in winter
and fresh cooled, dehumidified air in the summer.
Compared with the traditional fan coil, the newly designed Water Fan Coil is thinner,
and quieter. It can be installed in various ways such as floor installation, wall
installation, or ceiling installation, reducing the installation cost.
NOTE:
CXI units do not ship with a valve, it is not required to install zone valves with our fan coils, the fan will simply
shut off when the room reaches its set point. A valve (24vac) can be added if needed. Also the valve control
output can be used to operate a relay to stop/start a pump.
5. Installation Precautions
5.1 To ensure that the installation is performed correctly and that the Fan coil will
perform perfectly, carefully follow the instructions indicated in this manual. Failure to follow
the instructions will not only can cause a malfunction of the Fan coil but also invalidate the
warranty and hence the manufacturer shall not be responsible for any damage to people,
animals, or property.
5.2 It is important that the electrical installation is performed according to national electric code,
And the instructions in this manual are followed and the unit is correctly grounded.
5.3 The fan coil must be installed in a position that allows routine maintenance, such
as filter cleaning.
5.4 Positioning the unit
5.5 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.
5.6 Make sure that:
-the wall on which the unit is to be installed is strong enough to support the weight;
-the section of the wall chosen does not have pipes or electric wires passing through;
-the selected 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 or a condensate pump may be used.
5.7 Minimum clearances -------floor installation& wall installation, see page 11.
5.8 Figure 1 indicates the minimum mounting distances between the wall-mounted
cooler-convector and furniture present in the room. See page 11.

CHAPTER 3 INSTALLATION
1. Installation precaution
•To ensure that the installation is performed correctly and the unit operates at optimum
performance, carefully follow the instructions in this manual. Not following the instructions can
cause malfunctions of the appliance and also invalidate the warranty. Chiltrix will not be
responsible for any damage to persons, animals or property caused by improper installation or
operation.
•It is important that the electrical installation is compliant with all NEC and local electrical codes.
•The appliance must be installed in a suitable position for easy access when cleaning the filter and
general maintenance.
2. Installation position
The minimum distance from the floor to the lower line must be 3.25”. The minimum distance of
the air outlet grill from any possible obstacle must be 5.5”. The minimum distance between side
and side wall must be at least 1”, to allow you to remove the cover.
Figure 1
3. Wall mounted Installation
3.1 Removing the side panel (same procedure for both sides)

12
First remove the top grill (A), by removing the screws. Next take out the small rubber plug (B),
and unscrew the holding screw (C). Then move the side (E), to the left, and lift the side
upwards.
Wall installation or vertical floor mounts
Using the paper template, trace the position of the wall (fig.10). Drill the holes and insert the toggle
bolts (2 for each bracket) (fig.11 ref. A); attach the bracket (fig.11 ref. B) included with the FCU.

15
Before you install the unit on the floor, the feet should be mounted: First, lay down the
unit, take out the screws and two feet from accessories bag, then line up the screw holes, and attach
the feet with the screws. (See fig.12 and fig.13)

16
Figure 12 Installing the Feet
Figure 13
Do not over-tighten the screws so that the bracket can be adjusted with a spirit level (fig. 14).
Then fully tighten the four screws to block the bracket.
Mount the unit, checking that it fits correctly onto the bracket and that it is stable. (fig. 15).

17
Water Connection floor installation& wall installation
To connect the inlet and outlet water pipes, refer to the figures below.

18
The bellows shown are examples only, the bellows shipped are approximately 8” long.
Bellows NPT ¾ to fitting connection Bellows G3/4 fitting to CXI port, use the
white washer from the bag on this end.
NOTE* The bellows also serve as an adapter from the European thread on
the unit to NPT thread on the end you will connect to.
DO NOT REMOVE THE BELLOWS
Use blue monster 70885 PTFE thread seal tape or equivalent.

19
Condensate discharge
The condensate discharge network must be properly sized, (minimum inside pipe diameter 1/2
inches) and the piping must be positioned in such a way as to keep an inclination, of at least 1%.
The drain pipe (C) is connected to the pan (B), positioned under the heat exchanger coil (A). If
the condensate is discharged into the drainage system, it is recommended to install a p-trap to
prevent any pipe smell from entering the rooms. The p-trap must be lower than the pan.

20
Minimum Installation Distances-----Horizontal Installation
Figure 24 indicates the minimum mounting distances between the wall-mounted
Fan coil and furniture present in the room.
Side Opening
Lift the cover that protects the screw and remove the screw.
Move the side panel slightly and lift it out.
Ceiling of Horizontal Installation
Ensure that there is enough clearance around the unit,
according to installation dimension chart (fig. 5 or fig.6). Mark the relative screw holes
on the installation wall (fig. 26), then drill the holes, and then mount the unit.
Adjust the unit so it is 1-2° tilts towards the condensation drain-pipe port for better
condensation water draining.
Mount the unit, checking that it fits correctly on the bracket and it is stable.
