3. 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:
   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.

4. Installation Precautions
   • 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.
   • 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.
   • The fan coil must be installed in a position that allows routine maintenance, suchas filter cleaning.

Positioning the unit

• 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.
• 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 fl
  -the installation wall is preferably an outside perimeter wall to allow the discharge of condensation outside or a condensate pump may be used.
• Minimum clearances ——-floor installation& wall installation, see page 11.
• 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 cacause 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 ooperation.
   • It is important that the electrical installation is compliant with all NEC and local electrical code• 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 othe 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.

3. Wall mounted Installation
   3.1 Removing the side panel (same procedure for both sides)
   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 togglbolts (2 for each bracket) (fig.11 ref. A); attach the bracket (fig.11 ref. B) included with the FCU.

4. Mounting Bar and Water Hole MeaseurementsBefore 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)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).Water Connection floor installation& wall installation
   To connect the inlet and outlet water pipes, refer to the figures below.

5. Water Pipe ConnectionsThe 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.
   Use blue monster 70885 PTFE thread seal tape or equivalent.
   Installation tip for installing the white washers on the G3/4” side of the bellows. Flexible Washer Apply silicone grease to one side of the washerInsert washer into bellows with greased side facing out, install hand tight on fan coil
   The newer style white flexible washers are softer that the previous version hard washers and can be deformed or torn when tightening if you are not careful.
   We highly suggest to use silicone grease (NOT silicone sealer!) as shown above which will prevent deformation and/or tearing when tightening. You still need to be careful, do not over-tighten!

6. Condensation Lines
   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.

7. Ceiling or Horizontal Mounting
   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. Condensation piping

Connect a ½” CPVC elbow to the ceiling mount drain port, then using a ½” piece of CPVC pipe, extend the drain out the rear of the unit through the gap shown in the above picture.

CHAPTER 4 MAINTENANCE AND OPERATION

1. The following steps are taken after commissioning. These steps are for yearly maintenance and are not to be confused with flush/filling the system loop.
   Evacuating air after filling and commissioning the system,
   Use a screwdriver to unscrew the side breather valve (fig. 23 ref. A). When water starts coming out of the breather valve of the appliance, close it 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 once every 1-2 years, also, periodically check the pressure of the system loop on the rear of the CX34. Use a screw driver to loosen the bleed screw (A), and remove the air in the system.

2.  Maintenance
