Installation

DANGER

Danger of death! Gases are generated during the storage of slurry which remain partly dissolved in the liquid. If the slurry is strongly agitated during mixing and purging, poisonous, explosive gases

such as hydrogen sulphide and methane are released. If an ignition source is present, the released gas can explode.

To avoid damage during operation, please observe

the following:

– Switch off the heater before mixing and purging

the slurry.

– Close the slide valves when storing slurry out-

side.

– The fan for the air supply must not be part of a

closed pipe system.

– Respect the safety distance of the heater to

inﬂammable materials, see “Installation position”.

– Consult your ﬁre insurance provider and/or local

ﬁre protection engineer to assess the foresee-

able, general risk of ﬁre.

– For cleaning, care and maintenance, note the

applicable national regulations and directives.

– No condensation permitted. Comply with am-

bient temperature, see page27 (Technical data).

Siphon connection

DANGER

Risk of poisoning!

– If the TR is operated without a siphon or with

an empty siphon, toxic ﬂue gases may escape.

▷

A siphon must be connected before commissioning. This prevents the escape of toxic ﬂue gases and will also collect any condensate contained in the ﬂue gas.

▷

The siphon is not included in the delivery and

must be ordered separately for the nominal size of DN40.

▷

Fill the siphon with water before commissioning.

▷ If large volumes of condensate are discharged,

we recommend that an additional drain pipe is connected to the siphon.

▷

If the heater has not been used for a lengthy period, the siphon must be checked, cleaned and ﬁlled with water before commissioning.

• Unscrew the siphon, remove it and ﬁll it until

water ﬂows out of the side drain.

• Secure the siphon again and ensure that the seal

is correctly positioned.

unit, the heaterTR will be non-functional.

▷ In the event of faults which cannot be rectiﬁed

by authorized trained personnel, contact the supplier.

▷

The BCC can be removed from the burner control

unit and submitted for diagnostic purposes by agreement with the supplier.

ay l e

▷ If no other fault is active, the TR can be readied

for use again by inserting a new BCC. The BCC must be compatible with the TR75 and the gas type used.

Setting the switch-on delay

▷

If multiple heaters switch on at the same time, there can be a gas and/or power shortage on individual devices. To avoid this happening, adjust the switch-on delay using the potentiometer on the burner control unit.

▷ The potentiometer is set to 0s at the factory.

– +

▷ If necessary, a switch-on delay of 5 to 10s can

be set between the devices.

7 After completing the wiring, close the cover

and the housing cover on the burner control unit again.

8 Switch on the power supply.

▷

A circulating dash will be displayed when the voltage supply is switched on to indicate that the switch-on delay is running.

9 Release the gas supply. 0 Commission the heater.

Commissioning

CAUTION

To avoid damage to the heater TR, please observe

the following:

– The heater may only be commissioned once

it has been ensured that the heater, gas pipes, mains voltage supply and room thermostat have been installed by authorized trained personnel according to the regulations.

– During the initial commissioning procedure, the

direction of rotation of the main fan must be checked ﬁrst, see page 9 (Checking the direction of rotation of the main fan).

Cleaning

CAUTION

To ensure that no damage occurs during operation

and cleaning, please observe the following instructions. Otherwise, injuries or damage to the device may occur and/or the function of the device may be impaired, and the manufacturer’s warranty will be cancelled.

– Sharp-edged metal sheets. Always wear protec-

tive gloves.

– After cleaning, check that the components on

and in the heater are in good condition. The device may only be restarted if all safety devices have been installed and the safety functions have been checked.

– Clean the heater once a year when used in

horticulture and at regular intervals as well as after each fattening period when used in agriculture, as described below. Inadequate or irregular cleaning can cause the device to overheat and can thus lead to ﬁre damage or damage to the device. For example, dirt particles can catch

ﬁre and can be blown out of the device.

▷

The TR is made of high-quality stainless steel

and is resistant to external influences such as dirt and moisture.

▷ It is designed so that it can be cleaned carefully

both inside and outside with a high-pressure cleaner.

▷

The housing cover and cable glands on the

burner control unit must be closed during the cleaning process.

▷

The electrical components are protected from

moisture by additional water drip edges on the housing cover. Nevertheless, direct water inﬂuence on the edges of the housing cover should be avoided.

▷

A downward slope inside the device ensures that dirty water drains out.

▷

Never direct the high-pressure cleaner at the heater when it is set to water jet. Always use the spray setting.

▷

The distance between the nozzle and the surface

to be cleaned must always be at least 50cm. Too short a water jet from the high-pressure cleaner can cause serious damage to the device.

 Switch off the burner control unit.  Disconnect the system from the electrical power

supply.

GB-11

▷ The heater may only be disconnected from the

electrical power supply once the device has been switched off and post-cooling is complete.

 Shut off the gas supply. 4 Check the cover on the burner control unit and

the housing cover to ensure they are both tightly closed

> 50 cm

▷

The rubber seals between the electrodes and

electrode plugs may be displaced by the water

jet.

6 After cleaning, check that all the parts on and

in the heater are in the correct positions, for example whether the rubber seals between the electrodes and electrode plugs are ﬁtted correctly.

7 Remove the air ﬁlter and check it for dirt.

8 Tap the air ﬁlter. 9 The air ﬁlter can be rinsed under running water

if it contains stubborn dirt particles.

0 Chemical cleaning agents, disinfectants and/or

pesticides contain corrosive substances which can even corrode stainless steel. Always rinse the devices with water after cleaning using such agents to remove any residue of these agents from the surface.

 After cleaning, select operating mode 3 Con-

trolled air ﬂow so that the interior of the device can dry properly.

 After cleaning the heater, check it is functioning

faultlessly in normal operation, see page19 (Checking the safety functions and burner operation).

 When operating with LPG, check and clean the

breather oriﬁce of the pressure reducer.

Assistance in the event of malfunction

WARNING

To avoid harm to persons and animals or damage

to the heater, please observe the following:

– Electric shocks can be fatal! Before working

on possible live components, ensure the unit is disconnected from the power supply.

– Fault-clearance must only be undertaken by

authorized trained personnel!

– Repairs to components, e.g. the burner control

unit or the combination control, may only be carried out by the manufacturer. Otherwise, the

warranty will be voided. Unauthorized repairs or

incorrect electrical connections, e.g. the connection of power to outputs, can cause gas

valves to open and the burner control unit to

become defective. In this case, fail-safe opera-

tion can no longer be guaranteed.

– (Remote) resets may only be conducted by au-

thorized personnel with continuous monitoring

of the devices concerned.

▷

In the event of an installation fault, the burner control unit closes the gas valves and the status indicator light will be red at the latest after a restart has been unsuccessful.

▷

The 7-segment display will show a fault code

in the form of a letter with a decimal point and a number alternately indicating a warning. Together with the red status indicator light, this then constitutes a fault.

▷ Warnings and faults may be cleared only using

the remedies described below.

Internal wiring

▷

To rectify a fault, it is sometimes necessary to

check the internal wiring.

 Open the housing cover of the burner control

unit.

 Undo the two screws (M3) using a Phillips screw-

driver and remove the complete plastic cover from the burner control unit.

Chimney

Double-walled coaxial chimney with integrated ﬂue gas and air supply route, category C33.

▷ Internal/External diameter: 100/150 mm, maxi-

mum length: 5m.

CAUTION

To avoid damage during operation, please observe

the following instructions.

– The TR is only CE tested and approved with

the coaxial chimney described below.

– Do not exceed the maximum length of the

chimney. Otherwise the CE approval will be voided and the function of the device may be impaired. The supplier/manufacturer cannot accept liability for damage resulting thereof.

– Check the applicable building regulations,

standards and the relevant accident prevention regulations before installation. The same applies to the erection and maintenance of a scaffold.

▷

The design of the chimney depends on the prem-

ises and the roof construction.

▷

Before installation, the site and any wall mounting which may be required for a chimney length in excess of 2m must be deﬁned.

▷ The elements are sealed and connected using

clamp strips. Each chimney element is supplied with a clamp strip. A seal is provided for each clamp strip which is either integrated or supplied loose.

▷

The clamp strips are only designed for sealing

and connection purposes, not for absorbing axial forces.

▷ Any roof bushing depends on the roof construc-

tion and must be ordered separately.

Examples of application

This example of application shows the chimney as

a standard kit.

▷

The telescopic pipe is adjusted to minimum

length (maximum length) to match the wall height.

In this example of application, the chimney is routed sideways along the exterior wall rather than on the roof. Additional elbows from the accessories range are used for this purpose. Here, too, the maximum installation length is 5m.

If the chimney only has to bypass a single ob-

▷

stacle in the roof construction, its vertical installation position can also be compensated using a 45° elbow.
