SPLIT HORIZONTAL INVERTER UNITS
PACKAGED AIR-AIR
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.
