SAFETY P ECAUTIONS
•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. nqualified 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.
•se 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.
WA NING!
Before starting installation, service or maintenance, turn off the main power switch in order to
avoid electrical shock that may cause personal damages.
•When repairing the unit, use only original spare parts and install them properly in the same
position where old parts were placed.
•These units are designed to work with 100% recirculated air. The installation with 100%
outdoor air is prohibited. See application limits.
•Do not install the unit in explosive atmosphere.

D AINAGE
•Indoor drainage (of condensate water) has a 3/4” MPT connection.
•Condensate drain line diameter should be equal or larger than the unit connection depending
on pipe 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.
AI DUCTS
-Air duct dimensions will be determined according to the airflow and available static pressure.
-Ducts must be designed by qualified technical people.
-se ducts made of non-inflammable materials in order to avoid any emission of gas in case of
fire. It is advisable to use metal plate duct with insulation.
-se flexible ducts to connect air ducts into the unit and thus avoid vibration and noise
transmission.

ADJUSTMENT OF FAN T ANSMISSION
-Adjust transmission so that indoor fan-motor reaches its nominal value..
- If consumption is lower than the nominal value, the airflow is insufficient.
To change fan speed:
1. Remove the belt and slide the motor over the channel.
2. Loosen setscrews and turn the mobile flap around, depending on your needs.
3. Tight setscrews.
4. Put the belt back in the pulley’s channel.
5. Tight the belt using a tension adjuster screw.

To line up motor and fan pulleys:
1. Loosen setscrews from the fan pulley.
2. Slide the fan pulley down the axe and line up with the motor, using a ruler to make sure
that it’s in parallel with the belt.
3. Tight the fan pulley using a tension adjuster crew.
COMP ESSO LUB ICANT
-Compressors with R410a refrigerant use synthetic polyester oil, each manufacturer using a
specific oil for his product.
-The system must not remain open to the atmosphere more than 15 minutes.
-Due to its hygroscopic qualities, you must be very careful during manipulation: when synthetic
oils mix up with mineral oil, they deteriorate causing obstructions and even the breakdown of
the compressor. Do not mix them under any circumstance.

EF IGE ANT LINES
EF IGE ANT CI CUIT
Split systems demand a correct disposition of refrigerant piping and a correct connection between
both indoor and outdoor units.
Line selection should be done according to the following criteria:
-Pressure drop of the line
-Circulation speed of the refrigerant
-Refrigerant mass
DISCHA GE LINE
In heat pump operation, the gas line works as discharge line.
WA NING!!!
When working with the machines in operation, discharge line temperature is very HIGH and
could result in burns.
