2 - HANDLING
For your safety, wear protective gloves
The unit must be handled with care and kept at. Impacts may cause damage to the frame or the
body of the unit and adversely a󰀨ect its main functions and its appearance.
The unit should preferably be lifted by its mounting holes (Fig.1, m) and never by the condensate pan or the collars.
It is possible to carry out the installation using a fork-lift truck, as long as care is taken not to damage the unit.
The unit is placed inside the suspended ceiling. If the return has no duct, ensure that the rear of the unit is at a
su󰀩cient distance from the wall (X = min. 250 mm).

LEC declaration number
This device may be used by children aged eight and over, and by persons with limited physical,
sensory or mental capabilities, or by persons with insu󰀩cient experience or knowledge, provided
that they are being correctly supervised or provided they have received instructions on how to
use the device in complete safety, ensuring that they have a full understanding of any risks
involved. Children must not play with the unit. User cleaning and maintenance must not be
performed by children.
During normal use, this unit is intended to operate under the following conditions:
■Maximum altitude: 2000 m,
■Minimum and maximum storage temperatures: -20 °C/+65 °C,
■Minimum and maximum operating temperatures: 0 °C/+ 40 °C,
■Indoor return air maximum humidity level: 27°C DB (dry bulb) at 65% RH (Relative Humidity),
■Clean interior environment (no corrosive substances present).
The device is designed for indoor use, and requires protection from any form of impact. Protection
rating IP 20 IK02.
This device is designed to operate in an over-voltage category II and pollution degree 2 environment,
in accordance with IEC standard 664-1.
To ensure a pollution degree 2 environment, the device must be protected from water and oil
splashes, and the dust allowed to settle on it must be limited.

EN-19 COMFORT LINETM

4 - NSTALLATION AND CONNECTIONS
To prevent injury or damage to the unit or room, work must only be carried out by qualied
personnel.
4.1 - Mechanical connections
Ensure that the suspended ceiling panels can be
easily removed and that there is enough space to
carry out maintenance and servicing operations.
The COMFORT LINETM must be suspended from the
ceiling using 4 or 6 threaded rods either 6 mm or 8 mm
in diameter (not supplied), which are xed to the unit's
4 or 6 oblong holes using anti-vibration resilient mounts
(optional, g.3, a) or a nut/washer assembly positioned
on either side of the mounting bracket (g.3, b).
Note: CIAT strongly recommends the use of anti-
vibration resilient mounts when securing the unit,
in order to reduce the transmission of vibrations
through the building structure during operation.
For LI, LIk, LY and LYk models, the unit should ideally
be positioned inside the suspended ceiling in the
entrance corridor of rooms, with the supply air opposite
the window. The unit must never be placed in the centre
of the room.
■The unit must be perfectly level in
relation to the suspended ceiling to
prevent condensate draining problems
(see procedure for removing the
condensate pan on page 10.)
■If a room thermostat is tted, place it on
an inside wall (not behind a door) and at
a height of 1,50 m from the oor. Keep it
away from sunlight and all sources of
heat.
4.2 - Air connections
4.2.1 - Air quality
Comfort units are not designed to control the humidity
of outside air. Fresh air handling must be provided by
an independent system in accordance with accepted
engineering practice (see CIAT air handling unit ranges).
All collars must be connected, whatever
the model. None must be capped, either for
the supply or return air.
4.2.2 - Fresh air knockout
If the fresh air return leads directly outside, the duct must
not exceed 5 metres in length. The fresh air temperature
must not be below -10 °C. A rain guard grille and a lter
must be tted (at the installer's expense) to prevent water
or other material entering the duct from outside. If an
auxiliary fan is being used (supplied by the installer), the
ow of fresh air must be limited to 10% of the unit's
nominal ow rate to prevent noise, coil frosting or air
lter bypass problems.
4.2.3 - Adjusting the fresh air collars
(Fig.4):
Either remove or leave on the shims needed to obtain
the desired ow rate. The ow rate ranges are given on
the label on the casing. 2 shims for minimum ow, 1 shim
for medium ow, no shims for maximum ow.
The pressure di󰀨erence must be between 50 and 100
Pa in order to obtain the desired ow rate.
Maintain the controller in the "BAS" (down) position.
4.2.4 - Fitting and adjusting the return air
grille for assembly versions LI/LY (Fig.5).
The return air grille is tted using 11 screws (a).
To adjust the height of the grille, remove the 4 panel
screws (b) and adjust to the required height (max.
clearance 40 mm). Secure the 4 screws once more (c).
4.3 - Hydraulic connections
Water always ows into the bottom of the coil and exits
at the top.
For size 0, the pipes are positioned in the suspended
ceiling as shown in Fig. 6, a. For sizes 1 to 6, the pipes
are positioned in the suspended ceiling or raised oor
as shown in Fig. 6, b.
The coils are equipped (g.7) with a header coupling
with at face swivel nuts with a female thread, diameter
G ½˝ or G ¾˝ depending on the size of the unit, and an
O-ring (supplied by CIAT).
The header coupling is equipped with an air bleed valve
(g. 8, a) at the high point with partial draining at the low
points (g. 8, b) that can be manoeuvred using a 7 mm
Allen key or a at-blade screwdriver.
