1. OVERALL INFORMATION
HEATER CONDENS heating and ventilation devices are designed to be applied in buildings of small and medium capacity, espe-
cially as production and warehouse halls, car showrooms and service stations, sports halls and stadiums, sacral buildings and
churches, retail stores and wholesale outlets, agricultural facilities, exhibition surfaces. HEATER CONDENS is a special, dedicat-
ed solution to be connected to low water temperature sources (for ex. condensing boilers, industrial heat pumps). The main
advantages of HEATER CONDENS are the high temperature of exhaust air generated by the low temperature of water
supplied to a unit, maximum use of water coil surface – new geometry of coil construction (enhanced fins size, lower space
between fins), optimized airflow exhaust – in effect high air exhaust temperature generated on each speed of the fan.

3. GENERAL INFORMATION
HEATER CONDENS heating and ventilation devices are manufactured in compliance with standards concerning quality, ecology,
utility and work comfort. HEATER CONDENS devices are delivered ready-to-use in a cardboard package that is to protect from
mechanical damage. The package consists of: the device, the Manual (Operation and Maintenance Documentation) and the
Guarantee. If the optional automatic control in ordered, it shall be delivered in a separate package. Make sure all the aforemen-
tioned elements are in the package immediately after delivery. In the absence of any element, please fill in the suitable carrier
document.
4. ASSEMBLY
Before any installation procedures, consider the following aspects: easy access for maintenance works, access to water and
electrical installation, and appropriate air distribution in a room.
Each HEATER unit is equipped with a set of 2 interchangeable color inserts; to change the color, remove the insert from the
front panel and place the desired one back in place.
It is advisable to mount the device to the wall or the ceiling on original mounting brackets, supporting mount pins (not delivered
with the device), or supporting constructions (shapes and dimensions of the supporting construction may be individually de-
signed in compliance with durability and strength requirements).
In case of mounting to the ceiling, pay attention to the fact that air-release/venting of the device may be difficult so it is advis-
able to place the vent at the highest point of the pipework.
The device may be mounted to the wall with the use of a mounting bracket at the angle of 0°, 30°, or 60 °. A mounting brack-
et holder is made of a curved profile. It has two holes for vertical assembly. Assembly to the wall and/or to the ceiling is possi-
ble at different angles but it requires making necessary holes in the holder.

Operation and maintenance documentation HEATER CONDENS EC v202301
NOTICE !
To sustain proper functioning of the device keep a safe distance– 200 mm from its sides and 300 mm from its
backside (from the fan)
ATTENTION !
While drilling the holes in marked places be careful not to damage the coil by going deeper than 20mm!
Mounting bracket to the heater
The bracket set consists of a holder, two sleeves, two
M8 screws, and washers. To mount the bracket, drill
two Ø12-13mm holes in places visibly marked on the
casing. Insert sleeves into drilled holes and place the
bracket in. The included holder must be screwed with
M8 screws with washers.
Installation of mounting pins
To mount the heater to the ceiling, use M8 mounting
pins. Drill two Ø8-9mm holes in places visibly marked on
the casing. Mounting pins may be screwed into the
frame not deeper than 20 mm
Assembly of HEATER MIX air mixer
To mount the HEATER MIX air destratifier to the ceiling,
use M8 mounting pins. Drill two Ø8-9mm holes in places
visibly marked on the casing. Mounting pins may be
screwed into the frame of a heat exchanger to a maxi-
mum depth of 20 mm. Mounting pins and connecting el-
ements are not included in the unit

Operation and maintenance documentation HEATER CONDENS EC v202301
5. ELECTRICAL INSTALLATION
The electrical installation and connection to the power supply must be done in compliance with the existing regulations and
standards for the building industry.
The fan’s engine is equipped with an internal temperature limit fuse protecting the engine from overheating.
The unit set does not consist of: a feeding cable, or a master switch (see diagram)
The electrical installation must be done by an authorized person, acquainted with the Manual. The connection of the feeding
cable and master switch must be done in compliance with the electrical diagram (with or without the automatic control, de-
pending on the option chosen). Any damages incurred as a result of the aforementioned causes are not provided with the
Guarantee and the user will be charged with any costs of the device exchange. The connection of the automatic control should
be carried out following the electrical diagram.
In case of any doubts or problems, unplug the device and contact the device’s installer or SONNIGER Authorized Service.
6. WATER INSTALLATION
The installation of the unit should be done in a way enabling maintenance service; on both stub pipes, manual closing valves
should be installed to cut off the device. The feeding cables of the heater shall be connected following the symbols/marking on
the casing (inlet/outlet). In the case of an electromagnetic valve (with the option of the automatic control), it should be in-
stalled on the outlet as it may be damaged otherwise. When the pipework is being connected to the exchanger, secure the
connections of the heater from oscillating torque (see figure) that may cause leakage in the exchanger.
Heating medium
The connector pipes are at the back of the
device. When connecting the hydraulic
pipes/connections, make sure you secure
the connector pipes against rotational
torque. Notice that the connector pipes are
not strained by the pipes. The valve of the
heating medium is on the supply pipe and
the vent is on the return pipe.
Use flexible connections to allow the heater
to be turned to the sides. Depending on the
flexible connections, the maximum turn
is 70° - for HEATER CONDENS MAX,
78° - for HEATER CONDENS CR1, CR2,
CR3,
68° - for HEATER CONDENS ONE , to both
sides. The figure shows the maximum
angle to one side and 50° to the other with
minimal distance left for connections.

Operation and maintenance documentation HEATER CONDENS EC v202301
NOTICE !
 In case of any metallic knocks, vibration or increase in sound level check if the fan mounting/fixing does not work
loose contact the installer or SONNIGER Authorized Service
 If it is planed the operation of devices in a humid environment, it is necessary to secure electrical connections by
building a connection block in a special box that meets the appropriate IP class.
7. AUTOMATIC CONTROL - INSTALLATION
A set of automatic control may be used (powered 230V) that consists of the following:
INTELLIGENT electronic control panel with an automatic speed controller, weekly program, and BMS communication.
2-way water valve with actuator; valve should be installed on a return stub of the heater.
8. FIRST START
Do all the connections (electrical, water, and automatic control), check for tightness of all connections done by an installer, and
air-release/vent the device then start the device in the following sequence:
8.1 Switch on the mains,
8.2 Set the requested speed of the fan on the revs controller,
8.3 Set the requested temperature on the thermostat,
The fan operates continuously irrespective of whether the heater’s valve is opened or not.
9. TURNING OFF
To switch the device off do the following:
9.1 Set minimum temperature on the thermostat – after 7 seconds valve will be closed and the heating switched off.
9.2 Set the main switch to the “0” position (off); the fan the thermostat will be switched off)
10. OPERATION
The engine and fan used in HEATER CONDENS units are maintenance-free devices but regular check-ups are advised, especially
motor and bearing (fan’s rotor should rotate freely, free from any axial and radial throws and undesired knocks/rattles).
11. MAINTENANCE
The heat exchanger requires systematical cleaning of all specks of dirt/impurities. Before the start of the heating period, the
heat exchanger is advised to be cleaned with compressed air directed to the air outlets; there is no need for dismantling the
device. Pay special attention when cleaning the exchanger’s fin due to the high possibility of damaging them. If fins are bent
use a tool specifically designated to carry out such repairs. If the device has not been used for a longer time, unplug it before
the next use.
The heat exchanger is not equipped with any fire protection device. The heat exchanger may be damaged if the room tempera-
ture goes below 0 C.
Anti-freeze liquid must be added to the water circulation/system. Anti-freeze liquid must be appropriate for the material the
exchanger is made of (copper) as well as other elements of the hydraulic system/circulation. The liquid must be diluted with
water according to the solution recommended by the anti-freeze manufacturer.
