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.

INDOOR TRANSMISSION ADJUSTMENT
• Adjust transmission so that the indoor motor consumption reaches its nominal value.
• If consumption is below the nominal value, then the airflow in the unit is too low.
- To change fan speed
1. In order to remove belt, move motor along its track
2. Loosen pulley set screws and rotate, if it is necessary, move flange.
3. Tighten set screws.
4. Replace belt in pulley channel.
5. Tighten belt using tensor screw.

- To align fan and motor pulleys:
1. Loosen fan pulley set screw.
2 Slide fan pulley along the shaft and align with motor using a ruler to be parallel with the belt.
3 Tighten the fan pulley set screw.
COMPRESSOR LUBRICANT
Compressors designed for 410A use POE oils. Each compressor manufacturer is using different oil for its products.
Compressors are designed for 410A use synthetic Each compressor manufacturer is using different oil for
his products. The compressor or system cannot remain open to atmosphere more than 15 minutes. Compared to
the mineral oil used with R22 compressors polyoilester lubricants absorb more than 100 times more the moisture.
Mineral oils or alkylbenzene-type synthetic oils are used for R22. Because R410A is not very soluble with conventional
oils, the latter tend to accumulate in the refrigerator circuit .That is why ester-type synthetic lubricants (POE,polyester)
which are highly soluble with R410A are used. Oils of this type are very hygroscopic, so they need to be handled more
carefully than conventional oils. Also, these synthetic oils deteriorate when they are mixed with mineral or alkylbenzene-
type oils and obstruct the capillaries or cause a breakdown in the compressor. Do not mix them under any circumstance.
