1.1 Prerequisites

Getinge has ESD protection integrated into the production and testing of electronic equipment, and also requires ESD protection to be used after delivery for the warranty to apply.

It is important to reduce the likelihood of ESD to avoid damage to sensitive electronic components. As a basic precaution, it is recommended to wear ESD wrist strap, sole grounders or conductive shoes when preforming maintenance on the unit. Keep electronic components in the anti-static bag until you are ready to install them in order to prevent charge from building up.

Requirements when performing maintenance to avoid ESD:

 Use ESD pads connected to the earth in accordance with the manufacturer’s

instructions to hold disassembled or new electronic boards during assembly work.

 Do not touch electronic boards with tools that may be charged, like

screwdrivers with a plastic or wooden handle.

 Use grounded tools, if necessary.  Always use an ESD wrist strap connected to the earth in accordance with the

manufacturer’s instructions when working in the electronic enclosure or when handling boards.

 Do not keep any foreign objects, such as drawings or plastic pockets, inside

the electronic box.

 Test the ESD protective equipment on a regular basis. To start with the maintenance/repair inspection the following steps should always be followed first:

 Check whether the mains plug of the unit has been pulled out.

  Attention! To avoid damage caused by electrostatic charging.

1.2 Danger of injury

 During troubleshooting, calibrating or validation of the unit it may be necessary

to turn on the unit with an open housing. You should do this with extreme care

1.2.1 Risk of electric shock

 Operating a running unit with open housing can result in an electric shock.

The areas marked in Pic 1 use mains voltage.

1.2.2 Risk of burning

 During operation, the heat elements can reach temperatures to 200°C.

Touching these parts or parts around them can result in severe burning.

1.2.3 Risk of Entrapment

 In standby mode, the sealer transport belt can start to move to avoid radiant

heat on the transport belt.



1.2.4 Tools

Tools needed to service and repair the unit are:

 Allen key 

 Circlip pliers

 ESD protection

 Knife

 Non aggressive solvent and degreasing agent

 Pinch pliers

 3M VHB cleaner

2 Preventive maintenance plan

In order to avoid damage or a failure of the unit as a result of insufficient maintenance we recommend servicing the unit at least once every year or after 100,000 seals. During maintenance the above-mentioned precautions should be followed. The sealing result should be checked after each maintenance.

2.3 Replacing the PTFE material

The belt guides and the heating rails are lined with a non-stick strip (PTFE tape). It is non-stick so your pouches will not stick on the heating rails. It is also on the belt guides which expands the life of the transportation belts. For preventive maintenance the PTFE material on the heating rails and belt guides must be replaced.

2.3.1 The belt guides

 The base frame has been removed from the housing.  Unscrew the belt guides (Pic 8)

Pic 8

 Press the upper belt guide down. The top of the upper belt guide can now move forward and the whole upper belt guide can be removed.(Pic 9)

Pic 9

 When the upper belt guide is loose, the lower belt guide can be pulled out.

SERVICE MANUAL ProSeal Classic/Plus/Premium

 Remove the press plate and the guide plate of the upper belt guide assembly

(Pic 10)

Pic 10

 Remove the worn PTFE strips on the guide plate and press plates.

 Clean off the bonding agent residues with a solvent and degrease the bonding

surface with a non-aggressive degreasing agent.

 Stick the new PTFE tape on the guide plate and press plate; do not touch the

cleaned bonding surface and press the tape over the complete area thoroughly.

 Reinstall the belt guide assembly. Make sure that the press plate moves

freely.

 See paragraph 4.3.2 for the mounting instruction of the belt guide assembly to

the base frame; for preventive maintenance, see paragraph 2.3.2.

2.3.2 The heating elements

 Disconnect the ground wire of the upper and lower heating element with a

plier.

  Attention! Do not pull the cables; this could damage the heating

elements! Use a plier on the connector.

 Remove the upper pressure roller (Pic 11) by releasing the pressure with

screw (1). After releasing the pressure remove the screws (2) to dismount the suspension of the upper pressure roller.
