INSTALLATION
Tools required
Pencil Drill Screwdriver Dowel (2 pcs.) Screws (2 pcs.)
Sucient service access to the unit for maintenance or repair operations must be provided.
The recommended minimum distances from the unit to the walls are shown below.
Make sure the unit has no foreign objects inside before starting it up.
The unit is designed for mounting to a horizontal surface adjacent to the wall with the ready-made holes for the air ducts. The xing brackets with a fastening hole enable xation of
the unit to the wall. The xing brackets are not included in the delivery set.

* the dimension may be increased during adjustment of the unit by means of the
levelling feet
The levelling feet on the bottom of the unit ensure exact alignment of the unit during
mounting.
For alignment of the unit loosen the nuts and adjust position of the support disc manually
using a wrench.Then tighten the upper and the lower nut.
To attain the best performance of the unit and to minimise turbulence-induced air
pressure losses while mounting connect straight air duct sections to the unit spigots.
Minimum straight air duct length:
• equal to 1 air duct diameter on outside side
• equal to 3 air duct diameters on outlet side
If the air ducts are too short or not connected at any unit spigot, protect the unit inner
parts from ingress of foreign objects by installing a protecting grille or other protecting
device with mesh side width not more than 1/2 inch to prevent uncontrollable access to
the fans.
Fasteners for the unit mounting are not included into delivery set and should be ordered separately.
While selecting appropriate fasteners consider material of the mounting surface as well as the weigh of the unit, refer to the technical data. For selection of the fasteners for unit
mounting please refer to a service technician.

The drain pan in the heat recovery section is equipped with a drain pipe for condensate removal.
Connect the pipe, the U-trap or U-trap of the other type (hydraulic lock) that is not included in the delivery set and a sewage system with metal, plastic or rubber connecting hoses.
Install the hoses with the minimum slope 3°.
Before starting operation of the unit make sure that the water ows freely into the sewage collection system, otherwise condensed water may build up in the unit during heat recovery,
which , in turn, may cause equipment failure and water ingress into the premises. Fill up the U-trap with water before using it. When using other U-trap systems read the installation
instruction to prepare the condensate drain system for operation.
For the units with a drain pump make sure that the exible hose from the pump must is connected to the sewage system.
The drain pump provides timely pumping of the condensed water from the unit.
to sewage system
MOUNTING OF HUMIDITY SENSOR NOT INCLUDED IN THE DELIVERY SET
The humidity sensor must be attached inside of the return air duct.
Open the unit, take o the upper part of the protecting housing and attach the humidity sensor to the holder located on the return air duct wall. Connect the humidity sensor
sockets to a respective plug on the control unit.
Update the control conguration after connection of the humidity sensor. Contact the product Seller for doing that.

MOUNTING OF RH, CO2OR VOC SENSOR FOR THE UNITS WITH S17 AND S18 AUTOMATION
The RH, CO2or VOC sensor must be installed in the return air duct.
Open the unit, disconnect the upper part of the protective housing and unscrew the holder that retains the inner partition box for the RH/CO2/VOC sensor. Disconnect the socket
using a screwdriver. Disassemble the RH/CO2/VOC sensor as described in the installation instruction and wire it according to the wiring diagram. Assemble the RH/CO2/VOC sensor
in the reverse order and install it on the holder inside of the unit. Update the control conguration after connection of the RH/CO2/VOC sensor. Contact the product Seller for doing
that.

Route the cables to the control unit through the sealed cabled glands in the unit.
All the electric connections must be performed in compliance with external wiring diagram and wired through the terminal block X1 in the control unit. Extra control units may
be optionally connected to the unit. Extra connected control units are not included in the delivery set and must be ordered separately. Extra connections are shown in dotted
lines in the wiring diagram.
EXTERNAL WIRING DIAGRAM FOR THE UNITS WITH S14 AUTOMATION
Connection of the re alarm panel (PK) contact
While connecting the re alarm panel contact remove the jumper between the terminals 4 and 5. In this case
the connection relies on a normally closed dry contact. In case of re the normally closed dry contact opens the
control circuit from the central re alarm panel and cuts o power supply to the unit.
Connecting of the external control unit contact, such as RH/CO2/VOC sensor
(NO, C).
Connect the CO2sensor to the terminals 6 and 7. In this case connection relies on a normally open dry contact.
Once the contact is closed, the unit starts to run with the maximum speed.
The cable for connection of the control panel to the air handling unit must be of 4xAWG30 type and have the
maximum length 39 3/8inch.

• The unit is rated for connection to 120V / 60 Hz power mains.
• The unit must be connected to power mains using insulated electric conductors (cables, wires). The actual
wire cross section selection must be based on the maximum load current, maximum conductor temperature
depending in the wire type, insulation, length and installation method.
• The external power input must be equipped with an automatic circuit breaker built into the stationary wiring
to open the electric circuit in case of overload or short-circuit.The circuit breaker installation place must provide
quick access for emergency shutdown of the unit. The trip current of the automatic circuit breaker QF must
exceed the maximum current consumption of the unit (refer to the technical data table). The recommended trip
current of the circuit breaker is the next current in the standard trip current row following the maximum current
of the connected unit. Automatic circuit breaker is not included in the delivery set.
