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 su󰀩cient 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.

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 ∅).

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 insu󰀩cient tightening torque may result in gas leaks, while an
excessive torque may damage the pipe are and allow gas to escape.

16 - PRESSURE AND CHARGE TEST
Since it is forbidden to discharge R410A into the atmosphere
(standard NF EN 378-2 paragraph 6.3.4.1), R410A may not be
used in pressure tests on the refrigerant connections.
-Remove the plugs from the CL2 shut-o󰀨 valves and open the
valves (anticlockwise).
Shut-o󰀨 valve plugs
-Ret the plugs on the shut-o󰀨 valves.
-Use the charging valve (Schrader) on the CL2 to ll the outdoor
module, two refrigerant pipes and evaporator with nitrogen and
helium (if you have a helium detector) up to a pressure of 10
bar.
-Check all the connections for leaks
R410A evacuation and charging
-Evacuate the pressure from the circuit.
-Connect the manifold to the gas charging valve (Schrader) on
the CL2. Connect the vacuum pump.
-Evacuate the CL2, the two pipes and the evaporator to obtain
a value of -0.1 Mpa (-76 cm Hg).
-Turn o󰀨 the vacuum pump and make sure the pressure remains
stable for ve minutes.
-Disconnect the vacuum pump.
-Connect the R410A canister to the manifold, without tightening
it.
-Open the valve on the R410A canister momentarily to drain the
hose.
-Tighten the union on the manifold.
-Open the tap on the R410A canister to break the vacuum in
the installation.
-Disconnect one of the wires from the low-pressure pressostat.
-Before starting up the compressor, check that the operations
below have been carried out:
• Electrical connection (check that all the connections are
correctly tightened and that the voltage is stable and in
accordance with the data on the manufacturer's data plate).
• Connecting the refrigeration lines.
• Pressure test.
• Evacuation.
-To charge with R410A uid, if it is not possible to ll the unit
with all of the charge with the compressor o󰀨, power up and
start the compressor (close the contact on the external control
input):

Example: for 3 metres of pipes between the CL2 50 and the indoor
unit, the additional charge will be 3x61g.
For other congurations:
Top up the charge by checking the overheating and the subcooling.
Values normally used:
-Overheating: 5 to 6K
-Subcooling:
• 3 to 4K for an evaporation temperature of 10°C
• 6 to 9K for an evaporation temperature of 0°C
-Once charging is complete, close the tap on the R410A canister.
-Stop the compressor and power o󰀨. Rewire the low pressure

18 - SERVICING AND MAINTENANCE
Before working on the unit, disconnect it from its electrical power source. For units equipped with orange terminals, raise all the orange
breaking devices and cut the 2 circuit breakers.
Working on the compressor:
-The compressor is fastened to the platform by four dia. 8 mm screws.
Warning: Do not tighten these screws to a torque of more than 13 Nm.
If you do not have a torque wrench, tighten them until they are snug then tighten a further ¾ turn.
Recommendations:
Take the operating readings and perform the checks listed in the table on the previous page at least once a year.
To ensure your unit runs smoothly and to obtain service under the warranty, take out a maintenance contract with your installer or an
approved maintenance company.
With the unit running, check it thoroughly for any abnormal visual signs or noises.
Make sure there are no traces of oil around the unit.
Specic details and mandatory checks relating to the use of refrigerant uid
In accordance with Regulation (EC) No. 842/2006 on certain greenhouse gases.
R410A refrigerant uid is a gas which has the following impact on the environment:
1. No impact on the OZONE layer: ODP (Ozone Depletion Potential) rating = 0.
2. Impact on the greenhouse e󰀨ect: GWP (Global Warming Potential) = 2088.
-Users must have units containing over 3 kg of refrigerant periodically checked for leaks by qualied personnel (2 kg in France,
decree and order of 7 May 2007). Regardless of the refrigerant charge in your system, CIAT requires that this check be carried out
in order to keep your system in good working order.
-Users of any system containing over 3 kg of refrigerant (2 kg in France) are required to keep a log of the quantities and types of
refrigerants used, added or recovered, and to include the dates and results of leak checks. The name of the technician and his
company must also be recorded. CIAT strongly recommends keeping such a log even if the refrigerant load of your system does
not require one.
-A leak check must be carried out one month after any leak repairs.
-System users are responsible for collecting used refrigerant and having it recycled, regenerated or destroyed.
Mandatory check each year
Detection of leaks on the refrigerating circuit.
