3. GENERAL INFORMATION

HEATER heating and ventilation devices are manufactured in compliance with standards concerning quality, ecology, utility and

work comfort.

HEATER devices are delivered ready-to-use in a cardboard package that is to protect from mechanical damages. The package

consists of: the device, the Manual (Operation and Maintenance Documentation) and Guarantee. If the optional automatic

control ordered, it shall be delivered in a separate package. Make sure all the aforementioned elements are in the package

immediately after the delivery. In the absence of any element, please fill in the suitable carrier document.

4. ASSEMBLY

Prior to any installation procedures, take the following aspects into consideration: easy access for maintenance works, access to

water and electrical installation, appropriate air distribution in a room.

Every HEATER unit is equipped with a set of 3 interchangeable color inserts; in order 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

designed 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 advisable

to place 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 bracket

holder is made of curved profile. It has two holes for vertical assembly. Assembly to the wall and/or to the ceiling is possible at

different angles but it requires making necessary holes in the holder.



ATTENTION !

!Przed Before mounting read the manual carefully and adhere to the rules concerning the mounting procedures. Not

applying may result in inappropriate functioning of the device and the loss of the guarantee rights.

!Pay special attention when working with electrical elements of the device.

!Any installation operations must be carried out by qualified persons with appropriate authorizations

NOTICE !

!To sustain proper functioning of the device keep a safe distance– 200mm from its sides and 300 mm from its

backside (from the fan)



Mounting bracket to the heater

The bracket set consist of: a holder, two

sleeves, two M8 screws and washers. In

order 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 HEATERMIX air mixer

To mount HEATERMIX air mixer 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 the maximum depth of

20mm. Mounting pins and connecting

elements are not included with the unit.

5. ELECTRICAL INSTALLATION

The electrical installation and connection to power supply must be done in compliance with the existing regulations and

standards for building industry.

The fan’s engine is equipped with the internal temperature limit fuse protecting the engine from its overheating.

The unit set does not consist of: a feeding cable, 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 electrical diagram (with or without the automatic control, depending

on the option chosen). Any and all 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 in accordance with 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 in order to cut off the device. Feeding cables of the heater shall be connected in accordance with the

symbols/marking on the casing (inlet/outlet). In case of electromagnetic valve (with the option of the automatic control) it should

be installed 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.

7. AUTOMATIC CONTROL – INSTALLATION

A set of automatic control may be used (powered 230V) that consists of the following:

COMFORT panel – including room thermostat and switch for regulation of 3 speeds of fan. One

COMFORT panel may regulate up to 3 pcs of HEATER units

2-way water valve with actuator; valve should be installed on a return stub of the heater

INTELLIGENT electronic control panel with an automatic speed controller, weekly program and BMS

communication. One INTELLIGENT panel may regulate up to 2 pcs of HEATER units

Splitter MULTI 6 - control up to 6 pcs of HEATER units from one COMFORT or INTELLIGENT Panel

The system is ready to start once the connections between the thermostat and the valve actuator are done, 230V power is

supplied to the thermostat and the fan’s motor is powered by the revs controller.

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 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 78°

to both sides. Figure shows maximum angle to

one side and 50° to the other with minimal

distance left for connections.

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:

1. Switch on the mains,

2. Set requested speed of fan on revs controller,

3. Set requested temperature on 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:

1. Set minimum temperature on thermostat – after 7 seconds valve will be closed and heating switched off.

2. Set main switch to the “0” position (off); fan will be switched off and the thermostat will be off the power.

10. OPERATION

The engine and fan used in HEATER 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 all dirts /impurities off. 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 of the

device. Pay special attention when cleaning the exchanger’s fin due to 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 period of 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

temperature 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.

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
