3. BRIEF DESCRIPTION OF THE UNIT
• The air handling units are intended for ventilation of small and medium-sized spaces (eg. single family
houses, ofces, etc.), having operating ambient temperature and relative humidity. The unit is intended to
be installed in the domestic or non residential premises. Mineral wool is used for thermal insulation and
sound attenuation. Units cover panels are 25–50 mm thick. As standard, the unit is designed for indoor
placement. In cold, wet rooms possible icing or condensation on the housing inside and outside. The op-
erating temperature range for the unit is -30 °C ... +40 °C, outdoor air temperature. Extracted indoor air
temperature +10 – +40 °C, relative humidity (non-condensing) 20–80 %.
• The air handling unit is not to be used to transport solid particles, even not in areas where there is a risk of
explosive gases.
• The units are equipped with a rotary heat exchanger or with a plate heat exchanger (may be replaced with
summer cassette, when recuperation is needless), air lters, an electric or water heater, fans and automa-
tion control system, to ensure safe and efcient operation of the unit.
• Before you open the door, the unit must be switched off and the fans must have been given time to stop (up
to 3 minutes).
• The unit contains heating elements that must not be touched when they are hot.
• We recommend to leave air handling unit in working mode (minimum 20 percent of power) during the rst
operation year. Due to moisture in building constructions, condensation may occur inside and outside the
air handling unit. Continuous operation of the equipment will signicantly reduce the risk of condensation.

• To maintain a good indoor climate, comply with regulations and, to avoid condensation damage, the unit
must never be stopped apart from during service/maintenance or in connection with an accident.
• If the unit is placed in spaces with high humidity, condensation might occur on the surface of the unit when
outdoor temperatures are very low.
• Under conditions, when the outdoor air temperature is low and humidity is high, risk of heat exchanger
frosting may appear. For this reason anti-frost protection function is foreseen in the controller of the Kom-
fovent air handling units. Depending on the type of the recovery, different methods of anti-frost protection
are available: cold air by-passing, or / and supply air fan speed reducing. For extremely low outdoor air
temperature the duct mounted preheater is recommended. Counter cross ow heat exchanger is the mostly
sensitive for low outside air temperatures, as the risk of frosting appears in the temperature range from
0 to -5 °C and below. Standard aluminium cross-ow plate heat exchanger has better features, as the risk
of freezing appears only at -10 °C. The lowest risk and the highest resistance to cold outside air is a com-
petitive feature of the rotary heat exchanger, as it is not freezing even at the temperatures of -30 °C if the
humidity level of the air is appropriate.
• Selecting the management without pre-heater, but with cold air bypass the unit must be additionally
equipped with a secondary duct mounted heater.
During air handling unit operation the process of condensation could be caused because of cold outdoor air
or due to high ambient air humidity (3 picture).

Suppose that supply air temperature is -25°C. Ambient air temperature, where air handling unit is installed,
is +20°C. In this case, condensate may appear on the outer surfaces of the air handling unit when relative hu-
midity in room is in range from 23% up to 100% (from point where curves of outside and inside air temperatures
crosses till the maximum value).
In other case, suppose that supply air temperature is 0°C. Indoor air temperature where air handling unit
is installed is +20°C. In this case, condensate may appear on the outer surfaces of the air handling unit when
relative humidity in room is in range from 43% up to 100% (from point where curves of outside and inside air
temperatures crosses till the maximum value).
To avoid condensation on unit outer surface use following solutions:
1) There should be maintained a lower relative humidity in the room where air handling unit is installed;
2) Preheater should be installed to increase the supply air temperature

4. INSTALLATION
It is recommended to install the air handling unit in a separate room or in the attic on a hard smooth surface
insulated with a rubber mat. The minimum free space in front of the control panel should be not less than
700 mm. The free space over the top of the unit should be at least 300 mm (4 a, b Picture). Rubber vibration
absorbers must be used when unit is going to be mounted on the wall or ceiling.
The place for the unit must be selected with allowance for minimum access to the unit for maintenance or
service and must comply with safety requirements. Opening for inspection can not be smaller than dimensions
of the unit and unit itself must be mounted in a way, that if needed (for example in case of complicated repair)
it can be easily dismounted.

4.1. Condensate Drain Connections
All condensate drain connections must be correctly trapped. Incorrect trapping can result in ooding within the
unit and consequent ooding of the immediate area. Fill the drain trap with water before starting up the unit.
All drain lines should be insulated where passing through any space where damage from condensation
drip might occur. If the unit is installed in unheated premises the condensate pipe should be heat-insulated and
heated with heating cable.

The bend of the water trap can be repositioned by turning it to the right or the left. The drain line from the
water trap must be arranged so that it will not damage adjacent unit sections or building elements. If the drain
line is run through cold spaces, it should be insulated to prevent freezing. A heating cable may be required.

4.1.1. Water trap installation for a unit section mounted on the suction side
Since the fans in most air handling units are last in the chain of functions and generate sub-atmospheric pres-
sure inside the unit,it is very important to correctly install the water trap. Because of that reason condensate
can be hardly eliminated from the air handling unit and the technical premise may get covered with condensate.
Height H1must be at least equivalent in mm to half of the negative pressure inside the unit in mm water gauge.
Height H2must be at least equivalent in mm to the negative pressure inside the unit in mm water gauge.

Precaution: The drainage siphon should be mounted on the outlet t-
ting pipe of every drip tray for complete condensate drainage from the air
handling unit and prevention of penetration of offensive odours from an
efuent into the ventilation system.
In case of the outdoor operation of the air handling unit, the siphon and
the bleeders should be heated with an electric thermal cable (if ambient
air temperature tamb < 0 °C). The siphon and the bleeders should be heat-
insulated with an insulating material.
4.1.2. Water trap installation for a unit section mounted on the pressure side
Since the fans in most air handling units are not last in the chain of functions and generate over-atmospheric
pressure inside the cooling section. In such case the consisted condensate can be easily removed from AHU
and there will be no strict requirements for siphon‘s installation. A drainage siphon is enough with a minimum
rake.
RECOMMENDATION: The drainage siphon must be installed in connection with not less size pipe diameter.
Any drainage systems must not be connected directly to the municipal sewage system. The condensate tray
shall be easily accessible for cleaning and disinfection.
