CONTENTS
1 - INTRODUCTION
CONDENCIAT®CL2 series air-cooled condensation units are outdoor packaged units equipped as standard with:
-Low-noise scroll compressor.
-Air-cooled condenser.
-Axial fan(s) with variable speed control.
These are factory tested and supplied with a nitrogen charge.
2 - RECEIPT OF GOODS
Check the unit for any damage or missing components upon delivery. Note any damaged or missing parts on the delivery slip.
IMPORTANT: you must notify the carrier of any damage and/or missing parts by registered letter within three days of the
delivery date.
3 - EQUIPMENT IDENTIFICATION
Each unit has a name plate bearing an identication number.
Please state this number in all correspondence.
4 - WARRANTY
The warranty is eective for a period of 12 months from the date the unit is rst commissioned into service, provided said date occurs
within three months of the invoice date.
It is eective for a period of 15 months from the unit invoice date in all other cases.
NOTE: For further information, refer to the application of the CIAT warranty.
5 - SAFETY RECOMMENDATIONS
To protect against accidents while installing, commissioning and adjusting the unit, the following settings must be kept in mind:
-Pressurised refrigeration circuit
-Presence of refrigerant
-Presence of voltage
-Site of installation
-Temperatures up to 150°C
Only experienced and qualied persons may work on this equipment. The recommendations and instructions given in the maintenance
brochures and the special instructions on the labels must be followed.
Always comply with applicable standards and regulations.
IMPORTANT: before carrying out any work on the unit, make sure it is powered o.
6 - UNIT LOCATION
The installer must check the following points before handling, placing or connecting the unit:
-These units are intended for use outdoors, near a building, on a deck/patio or in a garden. Although it is rain resistant, it may be
installed under a shelter with adequate ventilation on all four sides.
-The ground or surface on which the unit is placed must be strong enough to support the weight of the unit.
-Position the unit above the average snow depth for the region where the unit is installed.
-The unit must be perfectly level.
-Leave sucient room around the unit to allow easy access for servicing and maintenance.
Sound level: our units are designed to operate quietly. However, as soon as you begin designing your system, you should take into
consideration the outdoor environment in order to estimate the radiated noise and the building type in order to estimate the noise
transmitted through the air and by solid materials (vibrations).
If in doubt, have an analysis performed by an acoustical engineer.

Now that you have chosen a location for your unit, you may begin installing it. Take into account the weight and dimensions of the unit
(see Technical characteristics table "Dimensions").
Caution: raise the unit carefully and keep it vertical.

13 - ELECTRICAL CONNECTIONS
CONDENCIAT®CL2 units conform to the requirements of the European Low Voltage Directive and, more specically, with those of
international standards EN 60335-1, EN 60335-2-40, EN 61000-6-1, EN 61000-6-2, EN 61000-6-3 and EN 61000-6-4.
Always disconnect the unit before attempting to wire connections.
Open the roof as shown above, make the electrical connections as per the wiring diagram supplied with the unit and tighten the
terminals.
Remove the middle screw (rear section) Unclip at both ends Remove the roof
-The electrical characteristics of the mains supply must be identical to those on the name plate.
-The power supply must meet the requirements: 400 V
+6
-10
% 50 Hz for all models.
-All wiring must be connected in accordance with the regulations that apply to the installation site (e.g. NF C 15100 in France).
-The cable must be carefully chosen based on the maximum current of the unit (see table of electrical characteristics), the distance
of the unit from the main supply point, the upstream protection and the neutral operating conditions.
IMPORTANT: Connect the unit to earth before making any other electrical connections.
A main cut-o switch must be installed on the unit.

-External control input: this potential-free (dry) contact positioned between terminals 1 and 2 is used to start the compressor
• Contact closed = on
• Contact open = o
-To avoid damage to the compressor, the number of on/o cycles must not exceed 10 per hour.
-Information to be taken into account for the contact quality: the current passing through it is 35mA at 230V.
-Fault reporting outputs: they indicate that one of the 2 pressure switches has been deactivated.
-Contact characteristics:
• Minimum current: 10 mA
• Minimum voltage: 10 V
• Charge: 4000 Va for AC1, 750 VA for AC15
14 - SETTING THE CONTROL AND SAFETY DEVICES
High pressure switch with manual reset: deactivated at 41.5 bar
Low pressure switch with automatic reset: deactivated at 2.5 bar/activated at 4.5 bar
Condensation pressure control: 24 bar regulation (factory setting)

15 - REFRIGERANT CONNECTIONS
Once the outdoor and indoor units have been installed, the refrigerant connections must be made to link the units. When doing this,
apply the installation standards and carefully study the pipe diagram, ensuring the shortest distance and the smallest number of
elbows. Likewise, avoid restrictions by ensuring the shallowest possible curves on the elbows (curve radius greater than 3.5 x ∅).

To calculate the equivalent length, take into account the accessories pressure drops.
Equivalent elbow lengths at 90º:
Pipe diameter (inches) 3/8” 1/2” 5/8” 3/4” 7/8”
Equivalent length (m) 0,35 0,45 0,55 0,65 0,70
Preparing the pipes
For refrigerant pipes, only use refrigeration grade copper tubes (Cu-DHP type in accordance with standard ISO 1337), insulated,
degreased and deoxidised, suitable for an operating pressure of at least 4200 kPa and minimum burst pressure of 20,700 kPa. Domestic
water type copper pipes must never be used.
-Smooth the ends of the pipes by inclining them downwards. Make sure there is no contamination inside the pipes.
-Remove the are nuts from the unit and place them on the pipe. Flare the ends of the pipes
-Characteristics of a properly ared pipe:
• Smooth, polished inner surface.
• Polished, even outer edges.
• Conical are, uniform length.
-Insulate the two pipes.
Connecting the units
-Connect the two units.
For the CL2, tighten the are unions using two wrenches.
If these two wrenches are not used, there is a risk of breakage, which will void the warranty.
-Tighten the pipes to the correct torque given in the table below. An insucient tightening torque may result in gas leaks, while an
excessive torque may damage the pipe are and allow gas to escape.
