SAFETY PRECAUTIONS
Installation and maintenance of air conditioning equipment can be dangerous because the system is under pressure,
because some of its elements have high temperatures and include electrical components.
Only qualified and trained service staff should install, commission and carry out maintenance works. Unqualified staff
should only carry out basic tasks such as cleaning and replacement of filters, etc.
In every visit, all precautions should be taken into account: those recommended in the Installation, operation and
maintenance instructions, as well as the ones indicated in labels of the unit. Do not forget to strictly follow any other
safety codes.
Use safety glasses, work gloves and any other safety accessory necessary.
For brazing operations use a quenching cloth and have at close distance a fire extinguisher.
When repairing the unit, use only original spare parts and install them properly in the same position where old parts
were placed.
The equipment is designed to work with 100% recirculated air. For installations with external air supply, consult our
commercial department.
Do not install the unit in explosive atmosphere.
Before starting installation, service or maintenance, turn off the main power switch in
order to avoid electrical shock that may cause personal damages.

DRAINAGE
Indoor drainage (of condensate water) has a 3/4” gas
connection.
Condensate drainage pipe diameter should be equal or
larger than the unit connection depending on line
length and general building configuration.
Drainage line should have a minimum inclination of 2%
for proper water evacuation.
When drainage line is exposed to temperatures below
0ºC, it is necessary to provide thermal insulation or
electrical heating wire to avoid water freezing and tube
damages.
It is advisable to install a trap with proper dimensions.
AIR DUCTS
Air duct dimensions will be determined according to the airflow and available static pressure.
Ducts must be designed by qualified technical people.
Use ducts made of non-inflammable materials in order to avoid any emission of gas in case of fire. It is advisable to
use metal sheet duct with insulation.
Use flexible ducts to connect air ducts on the unit and thus avoid vibration and noise transmission.
COMPRESSOR LUBRICANT
Compressors with R410a refrigerant uses synthetic lubricant with Ester base, each manufacturer uses specific oil for his
product. The system must not remain open to the atmosphere more than 15 minutes.
Due to oil qualities affect directly the correct work of compressor, you must be very careful during manipulation: Do not mix
the oil with other substances.

REFRIGERANT LINES
For more information on the dimensioning of the refrigeration lines, request document with reference 207682 Rev100.
COOLING CIRCUIT
Split systems demand a correct disposition of refrigerant piping and a correct connection between both indoor and outdoor
units.
Pressure drop of the line
Circulation speed of the refrigerant
Refrigerant mass
DISCHARGE LINES
In heat pump operation, the low pressure line works as high pressure line.
LINES POSITION
1. When indoor unit is at a lower level than outdoor unit:
It is not essential to install traps in the vertical line. However, it could be convenient to install some every 6 to 9 meters
in order to help oil return.
When working with the machines in operation, discharge line temperature is
very HIGH and could hurt people.

SPLIT HORIZONTAL INVERTER UNITS

2. When indoor unit is at the same level as outdoor unit:
Rise the suction line to a higher level than the exchanger in order to avoid liquid refrigerant back to the compressor.
3. When indoor unit is at a higher level than outdoor unit.
NOTES:
Refrigerant lines should be as short and straight as possible.
Use recommended diameters to reduce quantity of refrigerant in the system.

Fasten the tubes to fixe elements by means of braces to avoid vibration.
Carry out welding works in drynitrogen atmosphere inside the pipe to be welded -USE A BOTTLEWITH PRESSURE
REGULATOR- to avoid the appearance of oxide and to expel rest of polluting material or humidity. Use rods with a
minimum 15% of silver alloy.
Insulate suction line in order to avoid condensation. Liquid line will be insulated only when exposed to high
temperatures (solar radiation, etc.).
Horizontal segment of suction line: 4% pitch towards the compressor.

In addition to refrigerant, sometimes it’s necessary to add oil. For more than 25 meters, add 30 grams.
If liquid line is descendant andthere is a considerable height difference, you have tocompensate the excess pressure
before the expansion.
If liquid line is ascendant and there is a considerable height difference, the formation of gas refrigerant before the
expansion must be avoided.
If you do not find the right pipe diameter, you can use the immediately lower diameter. The system will function
normally only with a slight capacity reduction.
Units CSTIBA/CCHIBA are supplied with nitrogen charge at a pressure between 5 and 6 bar. Before proceeding
to any welding work, it’s necessary to remove this charge out of the circuit. Once you have finished, only qualified
and trained service staff can make the vacuum and charge with the right amount of refrigerant.
It is forbidden by law to expel refrigerant into the atmosphere; therefore, it is
necessary to recover all the refrigerant and to avoid leaks.
Units without valves come loaded with nitrogen pressure leak test. Drain with
caution previously the realization of unions.

REFRIGERANT CHARGE
Should it be necessary to add or recover refrigerant, do it always in LIQUID phase, never in gas or vapour phase
since this would cause wrong mixing conditions.
Due to its high pressure and quick evaporation, refrigerant R410A cannot be kept in liquid phase inside charge
cylinder because bubbles would form, making reading difficult. Use always a scale to charge the unit with refrigerant.
Repair immediately any refrigerant leak.
Never overcharge the system.
Never use compressor as a vacuum pump.
If symptoms of refrigerant loss appear during operation, it’s necessary to carry out a leak test. Leak detectors usually
employed with CFC and HCFC cannot be used with R410a, due to chlorine in its composition. A leak detector for
R134A can be used but the sensitibity will be lower (when sensitibity is 1 for R134A, it falls to 0,6 for R410A).
To find small leaks, you will need a detector for HCF. Sensitibity for R410A is approx. 23 grams per year.
If a gas leak is found, it will be necessary to remove and completely recover the refrigerant charge. Pressurize the
system with dry nitrogen. If no leakage is detected, then do the vacuum and charge again with refrigerant.
Never use oxygen to carry out leak tests. Oxygen reacts violently when in contact
with oil and could cause an explosion resulting in damage, personal injuries or even
death.
If it’s necessary to make welding operations, you must fill the circuit with dry
nitrogen. Combustion of R410A refrigerant generates toxic gases.
