eta eHACK Operating Instructions Manual

Brand: eta

Model: eHACK

Type: Operating Instructions Manual

eta eHACK is a precipitator device meant for installation in conjunction with heating boilers of the same make to enhance their performance and optimize energy consumption. It works by removing dust and other particles from the flue gas, resulting in cleaner emissions and improved efficiency. The device features an automatic cleaning mechanism that ensures continuous operation without the need for manual intervention. Additionally, it has built-in safety features such as sensors and switches to prevent any potential hazards during operation.

Installation

2 Installation

Assembly and installation only by qualified

specialist personnel

The assembly and installation may be performed

by specialist personnel with the corresponding

qualifications only.

Technical illustrations

The following description illustrates the retrofitting of a

precipitator on a size 1 eHACK boiler (20-45 kW) with

the fuel discharge on the left side.

The illustrations are equally representative for eHACK

boilers of size 2 and if the fuel discharge is located on

the right side.

DANGER!

Electric shock

There are live parts on the circuit boards. If

touched, they can cause injury and

property damage.

 Before beginning any work, isolate the system

completely from all power sources, ensure that it

cannot be switched back on, and verify that it is

safely isolated from supply.

Align boiler horizontally

Place a spirit level onto the boiler's panel to check the

horizontal alignment; use shims as needed.

Fig. 2-1: Check alignment

The horizontal alignment of the boiler is important

because the electrode in the precipitator must be

an equal distance away from the inner walls on all

sides.

Installing the sensor for the sliding rake position

Remove the panel from the rear of the boiler.

Fig. 2-2: Panel

Mount the additional sensor from the delivery scope in

the hole. The clearance from the plate should be about

2-3 mm.

Fig. 2-3: Sensor

If the current position of the plate makes it difficult

to adjust the distance, measure the distance from

the shaft to the end of the plate and add an additional

2-3 mm. Then mount the sensor at the correct distance

from the shaft.

Installation

Reattach the panel.

Removing the de-ashing maintenance cover

Remove the maintenance cover for the de-ashing from

the bottom of the boiler.

Installation

Inserting the sliding rake

When the sliding rake is inserted into the boiler, the

alignment of the cam on the bottom must be observed.

This must always be closest to the side of the boiler on

which the conveying system is mounted.

Fig. 2-9: Note the alignment of the cam

The sliding rake is already assembled. If the room

height is not sufficient to insert the entire sliding

rake, the rake can be dismantled in the middle. After

insertion, the sliding rake has to be screwed together

again.

Fig. 2-10: Sliding rake dismantled

Mounting the lever

Mount the lever for operating the cam on the sliding

rake. Install the lever so that it can actuate the cam.

Fig. 2-11: Cam

Fig. 2-12: Lever

Connect the sliding rake with the de-ashing

Attach the connecting rods of the sliding rake to the de-

ashing levers. For this purpose, use the two special

screws (see illustration).

Fig. 2-13: Securing the connecting rod

Installation

Installing the isolator

Remove the blind cover from the top of the ash box.

Fig. 2-14: Blind cover

Insert the isolator from the inside and fasten with the

screws.

Fig. 2-15: Isolator

Mounting the high voltage unit

Mount the support with the high voltage unit on the

boiler.

Fig. 2-16: High voltage unit

When threading in, ensure that the insulator is not

damaged. Fasten the support to the boiler using the

long nuts and screws. Only hand tighten the nuts and

screws.

Installation

Mounting the discharge electrode

Carefully insert the discharge electrode into the flue

duct so that it is not bent.

Fig. 2-18: Discharge electrode

Secure the discharge electrode with a washer and

screw.

Fig. 2-19: Washer and screw

The electrode must be in the centre of the precipitator,

so that the flue gas can be optimally cleaned.

Therefore, check the clearance of the electrodes to the

inner walls.

Fig. 2-20: Electrode

With the long nuts on the support of the high-voltage

unit, the alignment of the electrode can be adapted as

required. Once the alignment is correct, tighten the

screws.

Fig. 2-21: Adjusting the orientation with the long nuts

Installation

Installing the safety switch for the maintenance

cover on top

Install the maintenance cover on top of the flue duct.

Tighten the screws alternately and evenly.

Fig. 2-22: Maintenance cover

Install the safety switch with the screws only hand-tight

initially.

Fig. 2-23: Safety switch

To adjust the switch correctly, slide it upwards until it

touches the pin.

Fig. 2-24: Pin

Then slide the switch a further 2 - 3 mm towards the

pin, so that the switch is actuated and a "click" is

clearly audible.

Fig. 2-25: Switch set correctly

Now carefully tighten the fixing screws of the

safety switch. Do not fasten them too tightly,

because otherwise the switch is strained and does not

trigger correctly.

Installing the safety switch for the maintenance

cover of the de-ashing

Install the maintenance cover for the de-ashing on the

bottom. Tighten the screws alternately and evenly.

Fig. 2-26: Maintenance cover

10 www.eta.co.at

Installation

Thread the safety switch into the holder.

Fig. 2-27: Safety switch

To adjust the switch correctly, slide it towards the

maintenance cover until it touches the maintenance

cover.

Fig. 2-28: Switch touches maintenance cover

Then slide the switch a further 2-3 mm towards the

maintenance cover so that the switch is actuated and

a "click" is clearly audible. Now tighten the adjusting

nuts on the switch.

Fig. 2-29: Switch set correctly

Installing the cover

Mount the cover over the high voltage unit.

Fig. 2-30: Cover

Then attach the sticker with the safety notices to the

cover and the rear panel.

Fig. 2-31: Sticker

Connect boiler to potential equalisation

The boiler must be connected to the potential equaliza-

tion of the boiler room or the building. Country-specific

regulations must be observed.

Installation

The runners of the boiler features holes to

connect the potential equalisation (minimum

cross-section 6 mm²).

Electrical connections

3 Electrical connections

Electrical connection must only be made by

qualified specialist personnel

The electrical installation must only be performed

by specialist personnel with the corresponding

qualifications.

DANGER!

Electric shock

There are live parts on the circuit boards. If

touched, they can cause injury and

property damage.

 Before beginning any work, isolate the system

completely from all power sources, ensure that it

cannot be switched back on, and verify that it is

safely isolated from supply.

DANGER!

Do not carry out work on high voltage units

The housing of the high voltage unit may

not be opened or damaged as there are

parts inside it that are under high voltage.

Non-compliance with the above may

result in serious or fatal injuries.

DANGER!

Earthing of the boiler is required

Separate earthing is required for the boiler.

To do so, a connection must be established

between the boiler and the structural

potential equalisation in the boiler room

(minimum cross-section 6 mm²).

Electrical connections

Connecting the high voltage unit

Mount the circuit board [EM-C] next to the other boards on the electronics carrier. Then clamp the high-voltage unit

to the circuit board [EM-C], see the following diagram. Connect the earthing cable (PE) for the high voltage unit to

the fastening screw of the electronics carrier using the enclosed toothed disc. For the CAN bus connection between

the circuit boards [HA-C] and [EM-C], remove the yellow jumper on the circuit board [HA-C] and position on the [EM-

C] circuit board.

Electrical connections

Clamp the safety switch and the sensor

Clamp the two safety switches and the sensor for position monitoring pursuant to the diagram below. Secure the

wire that is connected to the [EM-C] circuit board on [S103] with a cable strip, so that it does not chafe.
