DRAINAGE
• The Kubic units are factory equipped with a condensate drain water pan tilted as recommended by ASHRAE (11mm /
m) to prevent excessive water accumulation and subsequent bacteria flourishing.
• Additionally, Kubic models ranging from 1402.2 up to 3002.2 have drains built into each battery in order to avoid excess
condensate
accumulation in the zone where the unit’s compressors are located. A siphon should be used on both drains
to aid the flow of liquid. However, total evacuation of condensates through these drains is not guaranteed. In order to
obtain the best possible drainage conditions, we strongly recommend the unit be fitted with the external condensate tray
accessory.
• Kubic series models 3502.2 up to 4502.2 the aforementioned drains are only installed when the condensate tray
accessory option is requested.
• All drains are fitted with 3/4" gas connections.
•The indoor drain (of condensate water) has an MPT 3/4” pipe
connection. The outdoor recovery drain (of condensate water) has MPT
3/4” pipe connection.
• Condensate evacuation line diameter should be equal or larger
than unit drain connection depending on line length and general
building configuration.
• The condensate line should be pitched a minimum 2% for proper water
evacuation.
• If the drain line is at below 0 temperatures, then is necessary to install thermal insulation or an electric wire heater to
prevent freezing which would damage the tube
• It is convenient to install trap with proper dimensions.
• With the condensate tray option, 2 drains are added in the outdoor section with a 3/4” male MPT connection.
AIR DUCTWORK
• Air duct dimensions are determined in function of air flow and available external static pressure.
• A qualified technician should design air ductwork layout.
• Use air ducts made of nonflammable materials, which in the case of fire will not emit toxic gases. It is advisable
to use insulated sheet metal ducts.
• Use flexible connections between air ducts and the unit to avoid vibrations and noise transmission.
